Sitrim
Sulphamethoxazole + Trimethoprim
Indications
Urinary tract infection
Indication detailsView
Cotrimoxazole is bactericidal in vitro to a wide range of Gram-positive and Gram-negative organisms, including Streptococcus, Staphylococcus, Pneumococcus, Neisseria, B. catarrhalis, Escherichia coli, Klebsiella, Proteus spp., Haemophilus, Salmonella, Shigella, Vibrio cholerae, Brucella, Pneumocystis carinii, Nocardia and Bordetella. A particularly high degree of activity is exhibited against Haemophilus influenzae, E. coli and Proteus spp., making Cotrimoxazole particularly suitable for the treatment of chronic bronchitis and urinary tract infections. Cotrimoxazole exerts its bactericidal action by the sequential blockade of two bacterial enzyme systems in the biosynthesis of Folinic acid in the micro-organisms. The synergy thus produced accounts for the high degree of bactericidal activity.
Indications are :
Indications are :
- Respiratory tract infections, including acute and chronic bronchitis (treatment and prophylaxis), bronchiectasis, lung abscess, lobar and broncho-pneumonia, Pneumocystis carinii pneumonitis, sinusitis and otitis media.
- Genito-urinary tract infections, including urethritis, acute and chronic cystitis, pyelonephritis, prostatitis and gonorrhoea.
- Gastro-intestinal tract infections, caused by Salmonella typhi and Salmonella paratyphi, including the chronic carrier state.
- Other infections, caused by a wide range of organisms confirmed to be susceptible to Cotrimoxazole and where the therapeutic benefits are considered to outweigh the possible occurrence of adverse events.
- Such infections include acute and chronic osteomyelitis, acute brucellosis, skin infections including pyoderma, abscesses and wound infections, septicaemia, bacillary dysentery and cholera (as an adjuvant to fluid and electrolyte replacement), nocardiosis and mycetoma.
Therapeutic classView
Anti-diarrhoeal Antimicrobial drugs, Sulphonamides & Trimethoprim
PharmacologyView
Cotrimoxazole having broad spectrum bactericidal activity against a wide range of gram-positive & gram-negative bacteria and some protozoa. Co-trimoxazole containing Trimethoprim and Sulphamethoxazole in a 1:5 combination exerts its bactericidal action by the sequential blockade of two bacterial enzyme systems in the biosynthesis of folinic acid in the microorganism.
DosageView
Cotrimoxazole double strength tablet: Over 12 years
- For mild to moderate infections: 1 tablet twice daily.
- For severe infections: 1.5 tablets twice daily.
- Long term therapy (>14 days): 0.5 tablet twice daily.
- Gonorrhoea: 2 tablets every 12 hours for two days or 2.5 tablets followed by a further dose of 2.5 tablets after 8 hours.
- For mild to moderate infections: 2 tablets twice daily.
- For severe infections: 2 tablets thrice daily.
- Long term therapy: (>14 days): 1 tablet twice daily.
- 6-12 years: 2 teaspoonful twice daily.
- 6 month-5 years: 1 teaspoonful twice daily.
- 6 weeks-6 months: 0.5 teaspoonful twice daily.
Side effectsView
The side effects like crystalluria, allergic reactions, haemolysis, thrombocytopenia, neutropenia, agranulocytosis etc. have been reported rarely with Sulphamethoxazole-Trimethoprim combination. Other side effects are less serious in nature such as malaise, headache, nausea and vomiting. These are normally transient and do not require withdrawal of treatment.
ContraindicationsView
- Hypersensitivity to trimethoprim or sulphonamides.
- Patients with documented megaloblastic anaemia due to folate deficiency.
- Patients showing marked liver parenchymal damage, blood dyscrasia, severe renal insufficiency, glucose 6-phosphate dehydrogenase deficiency.
PrecautionsView
Prolonged full dose treatment with sulfamethoxazole-trimethoprim combination is associated with the risk of macrocytic anaemia due to the drug’s interference in the conversion of Folic acid into Folinic acid. If this occurs, it can be reversed by giving Folinic acid. Care should be taken when giving this combination to diabetic patients receiving sulphonylurea drug for possible potentiation of action of sulphonylurea.
Pregnancy & lactationView
Pregnancy and during the nursing period, because sulphonamides pass the placenta and are excreted in the breast milk and may cause kernicterus.
StorageView
Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.
Sivicaine Heavy
Bupivacaine Hydrochloride + Dextrose
Sivicaine Heavy
Bupivacaine Hydrochloride + Dextrose
Indications
Subarachnoid anesthesia
Indication detailsView
Bupivacaine Hydrochloride & Dextrose is indicated for-
- Bupivacaine is indicated for lower abdominal surgery (including Caesarean section), urological and lower limb, including hip surgery, lasting 1.5 to 3 hours.
- Bupivacaine are indicated for intrathecal (subarachnoid, spinal) anesthesia for surgical and obstetrical procedures.
- Bupivacaine produces motor blockade of the abdominal muscles makes the solution suitable for performance of abdominal surgery lasting 1.5-2 hours. The duration of motor blockade does not exceed the duration of analgesia.
Therapeutic classView
Regional anesthesia
PharmacologyView
Bupivacaineis a long acting anaesthetic agent of the amide type. Bupivacaine & Dextrosehas a rapid onset of action and long duration. The duration of analgesia in the T10-T12 segments is 2-3 hours. Bupivacaine Hydrochloride produces a moderate muscular relaxation of the lower extremities lasting 2-2.5 hours. The motor blockade of the abdominal muscles makes the solution suitable for performance of abdominal surgery lasting 45-60 minutes.
DosageView
The doses recommended below should be regarded as a guide for use in the average adult. Spinal anaesthesia for surgery: 2-4 ml (10-20 mg Bupivacaine hydrochloride). The spread of anaesthesia obtained with Bupivacaine depends on several factors including the volume of the solutions and the position if the patients during and following the injection. When injected in the L3-L4 intervertebral space with the patient in the sitting position, 3 ml of Bupivacaine spreads to the T7- T10 spinal segments. With the patient receiving the injection in the horizontal position and then turned supine, the blockade spine spreads to T4-T7 spinal segments. It should be understood that the level of spinal anaesthetic can be unpredictable in a given patient.
Side effectsView
The adverse reaction profile for Bupivacaine is similar to those for other long acting local anesthetics administered intrathecally. Adverse reactions caused by the drug are difficult to distinguish from the physiological effects of the nerve block (e.g. decrease in blood pressure, bradycardia, temporary urinary retention), events caused directly (e.g. nerve trauma) or indirectly (e.g. epidural abscess) by the needle puncture or events associated to cerebrospinal leakage (eg. postdural puncture headache).
ContraindicationsView
Bupivacaine in Dextrose is contraindicated in patients with a known hypersensitivity to it or to any local anaesthetic agent of the amide type. The following conditions preclude the use of spinal anaesthesia: Severe hemorrhage, severe hypotension or shock and arrhythmias, such as complete heart block, which severely restrict cardiac output,Local infection at the site of proposed lumbar puncture ,Septicemia.
PrecautionsView
Bupivacaine should be given cautiously to the elderly, the debilitated patients and to children, to patients with epilepsy, respiratory impairment, impaired cardiac conduction, bradycardia, severe shock; porphyria; myasthenia gravis. Myocardial depression may be more severe and more resistant to treatment.
InteractionsView
Bupivacaine should be used with care in patients receiving antiarrhythmic drugs with local anaesthetic activity, as their toxic effects may be additive. Phenothiazines and Butyrophenones may reduce or reverse the pressor effect of epinephrine.
Pregnancy & lactationView
It is reasonable to assume that a large number of pregnant women and women of child-bearing age have been given Bupivacaine. No specific disturbances to the reproductive process have so far been reported, e.g. no increased incidence of malformations. It should be noted that the dose should be reduced in patients in the late stages of pregnancy
With recommended doses, Bupivacaine enters breast milk in such small quantities that there is generally no risk of affecting the breast feed child. At maternal serum levels of up to 0.45 µg/ml produced by the epidural use of Bupivacaine for vaginal delivery, Bupivacaine could not be detected in breast milk during the first 24 hours after delivery (detection limit 0.02 µg/ml).

Pediatric usageView
Use in children: Bupivacaine Hydrochloride is not recommended in patients younger than 18 years of age.
Use in elderly and renal impairment: Patients in poor general condition due to ageing or other compromising factors such as partial or complete heart conduction block, advanced liver or renal dysfunction require special attention, although regional anesthesia may be the optimal choice for surgery in these patients.

Overdose effectsView
Acute emergencies from local anaesthetics are generally related to high plasma levels encountered during therapeutic use or to underventilation (and perhaps apnea) secondary to upward extension of spinal anaesthesia. Hypotension is commonly encountered during the conduct of spinal anaesthesia due to relaxation of sympathetic tone, and sometimes, contributory mechanical obstruction of venous return.
StorageView
Store in a cool and dry place. Protect from light.

Lactulose
Indications
Osmotic laxative
Indication detailsView
Constipation (Chronic Constipation): In every case of chronic constipation, initial treatment should consist of a diet rich in fiber (vegetables, salads, fruits etc.) a generous amount of liquids and much physical exercise. Lactulose is only to be taken when these measures prove insufficient.
Intestinal flora disturbances:
Intestinal flora disturbances:
- In damaged to intestinal flora (e.g. following long-term antibiotic treatment)
- gall bladder diseases
- intestinal diseases ( Colitis, Diverticulosis, Megacolon)
Therapeutic classView
Osmotic purgatives
PharmacologyView
Lactulose is a synthetic disaccharide. Lactulose is metabolized in the colon by the saccharolytic bacteria, producing low molecular weight organic acids (mainly lactic acid), which lowers the pH of the colon contents, promote the retention of water by an osmotic effect; thus increasing peristaltic activity. Lactulose is minimally absorbed; therefore, the pharmacokinetics of the absorbed material are not relevant to the principal therapeutic action.
DosageView
In constipation ( chronic constipation):
- Adults: Initially 3-6 tea-spoons daily, In long-term therapy 1½-6 tea-spoons daily
- Children up to 14 years: Initially 3 tea-spoons daily, In long-term therapy 1-2 tea-spoons daily
- Infants and toddlers: Initially 1-2 tea-spoons daily, In long-term therapy 1 tea-spoon daily
- Adults: 1-2 tea-spoons daily
- Children: 1 tea-spoon daily
- Hyper-ammoniemia in hepatopathy: a maximum of 18-30 tea-spoons daily.
- In portal systemic encephalopathy: hourly doses of 6-9 tea-spoons of Lactulose solution may be used to induce the rapid laxation. When the laxative effect has been achieved, the dose may then be reduced.
Side effectsView
Occasionally flatulence, cramp and abdominal discomfort can occur at the beginning of treatment; this is rapidly eliminated by reducing the dose. Overdose can result in diarrhoea. In abuse, loss of electrolytes (primarily potassium).
ContraindicationsView
Hypersensitivity to either galactose and or lactose; galactose-free diet, gastro-cardial symptom complex, suspected intestinal obstruction.
PrecautionsView
Lactulose should be administered with care to patients who are intolerant to lactulose. The dose used in the treatment of (pre) coma hepaticum is usually much higher and may need to be taken into consideration for diabetics.
InteractionsView
There is no significant drug interactions with lactulose. The glycosidic effect of cardiac glycosides can be intensified by potassium deficiency in abuse.
Pregnancy & lactationView
US FDA Pregnancy Category of Lactulose is B. Studies show that Lactulose has no adverse effects. Decisions regarding use during pregnancy and lactation must be made by registered physician.
Overdose effectsView
There have been no reports of accidental overdosage. In the event of acute overdosage it is expected that diarrhoea and abdominal cramps would be the major symptoms.
StorageView
Keep in a dry place away from light and heat. Keep out of the reach of children.

Therapeutic classView
Dipeptidyl Peptidase-4 (DPP-4) inhibitor
PharmacologyView
Saxagliptin inhibits dipeptidyl peptidase IV (DPP-IV) enzyme resulting in prolonged active incretin levels. It elevates the circulating levels of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) which stimulates insulin secretion in pancreatic β-cells in a glucose dependent manner. It improves glycaemic control by reducing fasting and postprandial plasma glucose concentration in patients w/ type 2 DM.
DosageView
Recommended Dosage: The recommended dosage of Saxagliptin is 2.5 mg or 5 mg once daily taken regardless of meals. Saxagliptin tablets must not be split or cut.
Dosage In Patients With Renal Impairment: No dosage adjustment for Saxagliptin is recommended for patients with mild renal impairment (CrCl >50 mL/min).
The dosage of Saxagliptin is 2.5 mg once daily (regardless of meals) for patients with moderate or severe renal impairment, or with end-stage renal disease (ESRD) requiring hemodialysis (CrCl ≤ 50 mL/min). Saxagliptin should be administered following hemodialysis. Saxagliptin has not been studied in patients undergoing peritoneal dialysis.
Because the dosage of Saxagliptin should be limited to 2.5 mg based upon renal function, assessment of renal function is recommended prior to initiation of Saxagliptin and periodically thereafter. Renal function can be estimated from serum creatinine using the Cockcroft-Gault formula or Modification of Diet in Renal Disease formula.

Sixvit
Pyridoxine Hydrochloride
Indications
Vitamin B6 deficiency
Indication detailsView
Pyridoxine (vitamin B6) is used to prevent or treat low levels of vitamin B6 in people who do not get enough of the vitamin from their diets. Most people who eat a normal diet do not need extra vitamin B6. However, some conditions (such as alcoholism, liver disease, overactive thyroid, heart failure) or medications (such as isoniazid, cycloserine, hydralazine, penicillamine) can cause low levels of vitamin B6. Vitamin B6 plays an important role in the body. It is needed to maintain the health of nerves, skin, and red blood cells.
Pyridoxine has been used to prevent or treat a certain nerve disorder (peripheral neuropathy) caused by certain medications (such as isoniazid). It has also been used to treat certain hereditary disorders (such as xanthurenic aciduria, hyperoxaluria, homocystinuria).

Pregnancy & lactationView
Category A: Controlled studies in women fail to demonstrate a risk to the foetus in the 1st trimester (and there is no evidence of a risk in later trimesters), and the possibility of foetal harm remains remote.
Sizatoin
Phenytoin Sodium
Sizatoin
Phenytoin Sodium
Indications
Tonic-clonic status epilepticus
Indication detailsView
Parenteral Phenytoin is indicated for the treatment of generalized tonic-clonic status epilepticus, and prevention and treatment of seizures occurring during neurosurgery. Intravenous Phenytoin can also be substituted, as short-term use, for oral phenytoin. Parenteral Phenytoin should be used only when oral Phenytoin administration is not possible
Therapeutic classView
Adjunct anti-epileptic drugs
PharmacologyView
Phenytoin acts as an anticonvulsant by increasing efflux or decreasing influx of sodium ions across cell membranes in the motor cortex during generation of nerve impulses; thus stabilising neuronal membranes and decreasing seizure activity. It acts as an antiarrhythmic by extending the effective refractory period and suppressing ventricular pacemaker automaticity, shortening action potential in the heart.
DosageView
Oral: Epilepsy:
- Adult: Initially, 3-4 mg/kg daily as single dose or in divided doses. Alternatively, 150-300 mg daily increased gradually to 600 mg daily if necessary. Maintenance: 200-500 mg daily.
- Child: Initially, 5 mg/kg daily in 2-3 divided doses. Maintenance: 4-8 mg/kg daily in divided doses. Max dose: 300 mg daily.
- Adult: Adjunctive therapy with a benzodiazepine (e.g. diazepam): 10-15 mg/kg by slow inj or intermittent infusion at a max rate of 50 mg/min. Maintenance: 100 mg IV (or orally) given every 6-8 hr.
- Child: Neonates: 20 mg/kg as a loading dose, then 2.5-5 mg/kg bid; 1 mth-12 yr: 18 mg/kg as a loading dose, then 2.5-5 mg/kg bid; >12 yr: 18 mg/kg as a loading dose, then up to 100 mg 3-4 times daily.
AdministrationView
Should be taken with food. When administering to patients on nasogastric or other enteral feeds, do not administer feeds 2 hr before or after a dose. Be consistent throughout therapy in relation to feed times. Do not switch dosage forms/brands w/o prior consideration.
Side effectsView
Hypersensitivity, lack of appetite, headache, dizziness, tremor, transient nervousness, insomnia, GI disturbances (e.g. nausea, vomiting, constipation), tenderness and hyperplasia of the gums, acne, hirsutism, coarsening of the facial features, rashes, osteomalacia. Phenytoin toxicity as manifested as a syndrome of cerebellar, vestibular, ocular effects, notably nystagmus, diplopia, slurred speech, and ataxia; also with mental confusion, dyskinesias, exacerbations of seizure frequency, hyperglycaemia. Solutions for inj may cause local irritation or phlebitis. Prolonged use may produce subtle effects on mental function and cognition, especially in children.
ContraindicationsView
Phenytoin Sodium is contraindicated in patients with:
- A history of hypersensitivity to phenytoin, its inactive ingredients, or other hydantoins
- Sinus bradycardia, sino-atrial block, second and third degree A-V block, and Adams-Stokes syndrome because of the effect of parenteral phenytoin on ventricular automaticity.
- A history of prior acute hepatotoxicity attributable to phenytoin
- Coadministration with delavirdine because of the potential for loss of virologic response and possible resistance to delavirdine or to the class of non-nucleoside reverse transcriptase inhibitors.
PrecautionsView
Cardiovascular disease, e.g. sinus bradycardia, heart blocks; DM; hepatic impairment; hypoalbuminemia; porphyria; seizures (may increase frequency of petit mal seizures); debilitated patients; elderly. Caution in IV admin in hypotension, heart failure or MI, monitor BP and ECG during therapy. IV must be given slowly (too rapid admin may cause hypotension, CNS depression, cardiac arrhythmias and impaired heart conduction). Extravasation and intra-arterial admin must be avoided. Do not discontinue abruptly (may increase seizure frequency), unless safety concerns require a more rapid withdrawal. May impair ability to drive or operate machinery.
InteractionsView
Effects with other sedative drugs or ethanol may be potentiated. Enhances toxic effects of paracetamol, lithium. Increased risk of osteomalacia with acetazolamide. Decreased serum levels/effects with acyclovir, antineoplastics, benzodiazeines, ciprofloxacin, CYP2C9 inducers (e.g. carbamazepine), CYP2C19 inducers (e.g. rifampin), folic acid, vigabatrin. Increased serum concentrations with allopurinol, capecitabine, cimetidine, CYP2C9 inhibitors (e.g. fluconazole), CYP2C19 inhibitors (e.g. delavirdine), disulfiram, methylphenidate, metronidazole, omeprazole, SSRI, trazodone, trimethoprim. Increases metabolism of antiarrhythmics, anticonvulsants, antipsychotics, beta-blockers, calcium channel blockers, chloramphenicol, corticosteroids, doxycycline, oestrogens, HMG-CoA reductase inhibitors, methadone, theophylline, TCAs. Decreases levels/effects of clozapine, ciclosporin, tacrolimus, CYP2B6 substrates (e.g. bupropion, selegiline), CYP2C8 substrates (e.g. amiodarone), CYP2C9 substrates (e.g. celecoxib), CYP2C19 substrates (e.g. citalopram), CYP3A4 substrates (e.g. benzodiazepines), digoxin, itraconazole, levodopa, neuromuscular-blocking agents, thyroid hormones, topiramate. Increases levels/effect of dopamine, ticlopidine. Valproic acid may displace phenytoin from binding sites; and affect phenytoin serum concentrations. Transiently increases the hypothrombinaemia response to warfarin initially, followed by an inhibition of the response.
Pregnancy & lactationView
Category D: There is positive evidence of human foetal risk, but the benefits from use in pregnant women may be acceptable despite the risk (e.g., if the drug is needed in a life-threatening situation or for a serious disease for which safer drugs cannot be used or are ineffective).
Pediatric usageView
Pediatric Use: A loading dose of 15 to 20 mg/kg of Phenytoin intravenously will usually produce serum concentrations of phenytoin within the generally accepted serum total concentrations between 10 and 20 mcg/mL (unbound phenytoin concentrations of 1 to 2 mcg/mL). Because of the increased risk of adverse cardiovascular reactions associated with rapid administration Phenytoin should be injected slowly intravenously at a rate not exceeding 1 to 3 mg/kg/min or 50 mg per minute, whichever is slower
Geriatric Use: Phenytoin clearance tends to decrease with increasing age. Lower or less frequent dosing may be required
Renal and Hepatic Impairment Or Hypoalbuminemia: The liver is the site of biotransformation. Patients with impaired liver function, elderly patients, or those who are gravely ill may show early toxicity. Because the fraction of unbound phenytoin is increased in patients with renal or hepatic disease, or in those with hypoalbuminemia, the monitoring of phenytoin serum levels should be based on the unbound fraction in those patients.

Overdose effectsView
The lethal dose in pediatric patients is not known. The lethal dose in adults is estimated to be 2 to 5 grams. The initial symptoms are nystagmus, ataxia, and dysarthria. Other signs are tremor, hyperreflexia, lethargy, slurred speech, blurred vision, nausea, and vomiting. The patient may become comatose and hypotensive. Death is caused by respiratory and circulatory depression.
There are marked variations among individuals with respect to phenytoin serum levels where toxicity may occur. Nystagmus, on lateral gaze, usually appears at 20 mcg/mL, ataxia at 30 mcg/mL, dysarthria and lethargy appear when the serum concentration is over 40 mcg/mL, but as high a concentration as 50 mcg/mL has been reported without evidence of toxicity. As much as 25 times the therapeutic dose has been taken to result in a serum concentration over 100 mcg/mL with complete recovery. Irreversible cerebellar dysfunction and atrophy have been reported.
Treatment: Treatment is nonspecific since there is no known antidote. The adequacy of the respiratory and circulatory systems should be carefully observed and appropriate supportive measures employed. Hemodialysis can be considered since phenytoin is not completely bound to plasma proteins. Total exchange transfusion has been used in the treatment of severe intoxication in pediatric patients. In acute overdosage the possibility of other CNS depressants, including alcohol, should be borne in mind.

Indications
Schizophrenia
Indication detailsView
Aripiprazole is indicated for-
- Schizophrenia
- Schizoaffective disorder
- Acute manic and mixed episodes associated with Bipolar I Disorder
- Maintaining efficacy in patients with Bipolar I Disorder who are stabilized
Therapeutic classView
Atypical neuroleptic drugs
PharmacologyView
Aripiprazole is an atypical antipsychotic that has both dopamine and serotonin receptors activity. It is a partial agonist of dopamine D2 receptors that relieves the symptoms of schizophrenia. It is characterized as a dopamine system stabilizer. It is a potent partial agonist at serotonin 5-HT1A receptors and antagonist at 5-HT2A receptors. This is associated with improvement of depressive, cognitive and negative symptoms.
DosageView
For Schizophrenia: 10 to 15 mg, once daily, without regard to food. Dose increment should not be made before 2 weeks, the time needed to achieve steady state.
For Bipolar mania: 30 mg, once daily, without regard to food.
For Bipolar mania: 30 mg, once daily, without regard to food.
Side effectsView
Headache, constipation, asthenia, nausea, dyspepsia, vomiting, coughing, abdominal pain.
ContraindicationsView
Aripiprazole is contraindicated in patients who are hypersensitive to it or to any component of this product.
PrecautionsView
Aripiprazole may be associated with orthostatic hypotension (orthostatic lightheadedness).
Aripiprazole should be used with caution in patients with known cardiovascular disease (myocardial infarction or ischaemic heart disease, heart failure or conduction abnormalities), cerebrovascular disease, or conditions that would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medications).
Seizures occurred in aripiprazole-treated patients. As with other antipsychotic drugs, aripiprazole should be used cautiously in patients with Alzheimer's dementia.
Aripiprazole is not approved for the treatment of patients with dementia-related psychosis.

Aripiprazole is not approved for the treatment of patients with dementia-related psychosis.
InteractionsView
Caution should be exercised when aripipazole is taken in combination with other centrally acting drugs and alcohol. Carbamazepine could cause an increase in aripiprazole clearance and lower blood levels. Ketoconazole, quinidine, fluoxetine or paroxetine can inhibit aripiprazole elimination and cause increased blood levels.
Pregnancy & lactationView
Aripiprazole should not be used in pregnancy as no human trial is performed. Patients should be advised not to breast feed an infant if they are taking aripiprazole.
Overdose effectsView
Aripiprazole at doses up to 1080 mg causes no fatalities. The signs and symptoms observed with aripiprazole overdose included nausea, vomiting, asthenia, diarrhea, and somnolence.

Risperidone (Oral)
Indications
Unipolar and bipolar depression
Indication detailsView
Risperidone tablet is indicated for the treatment of-
- Acute and chronic psychoses
- Mania
- Schizophrenia
Therapeutic classView
Atypical neuroleptic drugs
PharmacologyView
Risperidone is a selective monoaminergic antagonist having a high affinity for serotoninergic 5-HT2 and dopaminergic D2 receptors. Risperidone binds also to alpha1 adrenergic receptors and with lower affinity, to H1 histamine and alpha2 adrenergic receptors. Risperidone has no affinity for 8 cholinergic receptors. Risperidone, as a potent D2 antagonist, improves the positive symptoms of schizophrenia but causes less depression of motor activity. Balanced central serotonin and dopamine antagonism may reduce extrapyramidal side effect liability and extend the therapeutic activity to the negative and affective symptoms of schizophrenia.
DosageView
Psychoses:
- 2 mg in 1-2 divided doses on 1st day then 4 mg in 1-2 divided doses on second day (Slower titration appropriate in some patients);
- Usual dose range 4-6 mg daily; doses above 10 mg daily only if benefit considered to outweigh risk (max. 16 mg daily).
- Elderly (or in hepatic or renal impairment) initially 1 mg daily in two divided doses increased in steps of 1-2 mg twice daily.
- Child under 15 years not recommended.
- Initially, 2 mg once daily increased if necessary in step of 1 mg daily; usual dose range 1-6 mg daily;
- Elderly (or in hepatic or renal impairment) initially 1 mg daily in two divided doses increased in steps of 1-2 mg twice daily.
- Risperidone should be generally administered at 1 mg BID initially, with increases in increments of 1 mg BID on the second and third day, as tolerated, to a target dose of 3 mg BID by the third day.
- Further dosage adjustments, if indicated, should generally occur at intervals of not less than 1 week. When dosage adjustments are necessary, small dose increments/decrements of 1-2 mg are recommended.
Side effectsView
Insomnia, agitation, anxiety, headache, less commonly drowsiness, impaired concentration, fatigue, blurred vision, constipation, nausea and vomiting, dyspepsia, abdominal pain, hyperprolactinaemia, urine incontinence, tachycardia, hypertension, edema, rash, rhinitis, cerebrovascular accident, neurtropenia and thrombocytopenia have been reported.
ContraindicationsView
Risperidone is contraindicated in patients with a known hypersensitivity to the product.
PrecautionsView
Special precaution should be taken in case of preexisting cardiovascular diseases, discontinue use if signs and symptoms of tardive dyskinesia occur, renal and hepatic impairment, elderly epilepsy, Parkinson's disease and in pregnancy.
InteractionsView
Risperidone May antagonize the effects of levodopa and dopamine agonists. Chronic administration with Carbamazepine reduces plasma clearance of Risperidone. Chronic administration with Clozapine may decrease the clearance of Risperidone. Risperidone may enhance the effects of certain antihypertensives.
Pregnancy & lactationView
Although, in experimental animals, Risperidone did not show direct reproductive toxicity, some indirect, prolactin- and CNS-mediated effects were observed, No teratogenicity effect of Risperidone was noted in any study. The safety of Risperidone for use during human pregnancy has not been established. In animal studies, Risperidone and 9-hydroxyrisperidone are excreted in the milk. It has been demonstrated that Risperidone and 9-hydroxyrisperidone are also excreted in human breast milk. Therefore, women receiving Risperidone should not breastfeed.

Risperidone binds also to alpha1 adrenergic receptors and with lower affinity, to H1 histamine and alpha2 adrenergic receptors. Risperidone has no affinity for 8 cholinergic receptors. Risperidone, as a potent D2 antagonist, improves the positive symptoms of schizophrenia but causes less depression of motor activity. Balanced central serotonin and dopamine antagonism may reduce extrapyramidal side effect liability and extend the therapeutic activity to the negative and affective symptoms of schizophrenia.
DosageView
Psychoses:
- 2 mg in 1-2 divided doses on 1st day then 4 mg in 1-2 divided doses on second day (Slower titration appropriate in some patients);
- Usual dose range 4-6 mg daily; doses above 10 mg daily only if benefit considered to outweigh risk (max. 16 mg daily).
- Elderly (or in hepatic or renal impairment) initially 1 mg daily in two divided doses increased in steps of 1-2 mg twice daily.
- Child under 15 years not recommended.
- Initially, 2 mg once daily increased if necessary in step of 1 mg daily; usual dose range 1-6 mg daily;
- Elderly (or in hepatic or renal impairment) initially 1 mg daily in two divided doses increased in steps of 1-2 mg twice daily.
- Risperidone should be generally administered at 1 mg BID initially, with increases in increments of 1 mg BID on the second and third day, as tolerated, to a target dose of 3 mg BID by the third day.
- Further dosage adjustments, if indicated, should generally occur at intervals of not less than 1 week. When dosage adjustments are necessary, small dose increments/decrements of 1-2 mg are recommended.
Side effectsView
Insomnia, agitation, anxiety, headache, less commonly drowsiness, impaired concentration, fatigue, blurred vision, constipation, nausea and vomiting, dyspepsia, abdominal pain, hyperprolactinaemia, urine incontinence, tachycardia, hypertension, edema, rash, rhinitis, cerebrovascular accident, neurtropenia and thrombocytopenia have been reported.
ContraindicationsView
Risperidone is contraindicated in patients with a known hypersensitivity to the product.
PrecautionsView
Special precaution should be taken in case of preexisting cardiovascular diseases, discontinue use if signs and symptoms of tardive dyskinesia occur, renal and hepatic impairment, elderly epilepsy, Parkinson's disease and in pregnancy.
InteractionsView
Risperidone May antagonize the effects of levodopa and dopamine agonists. Chronic administration with Carbamazepine reduces plasma clearance of Risperidone. Chronic administration with Clozapine may decrease the clearance of Risperidone. Risperidone may enhance the effects of certain antihypertensives.
Pregnancy & lactationView
Although, in experimental animals, Risperidone did not show direct reproductive toxicity, some indirect, prolactin- and CNS-mediated effects were observed, No teratogenicity effect of Risperidone was noted in any study. The safety of Risperidone for use during human pregnancy has not been established. In animal studies, Risperidone and 9-hydroxyrisperidone are excreted in the milk. It has been demonstrated that Risperidone and 9-hydroxyrisperidone are also excreted in human breast milk. Therefore, women receiving Risperidone should not breastfeed.

Trifluoperazine
Indications
Schizophrenia
Indication detailsView
Anxiety states: It controls excessive anxiety, tension, and agitation seen in neuroses or associated with somatic conditions. The treatment or prevention of nausea and vomiting of various causes. The management of psychotic disorders, such as acute or chronic catatonic, hebephrenic and paranoid schizophrenia; psychosis due to organic brain damage, toxic psychosis, and the manic phase of manic-depressive illness.
Therapeutic classView
Phenothiazine drugs
PharmacologyView
Trifluoperazine is one of the phenothiazine class of compounds and as such has many pharmacodynamic effects which relate to its therapeutic actions and side effects. The most notable action of phenothiazines is antagonism at dopamine receptors in the CNS. It is hypothesised that this action in the limbic system and associated areas of cerebral cortex is the basis of the antipsychotic action of phenothiazines, whilst in the medullary chemoreceptor trigger zone it appears to be responsible for the antiemetic effect of these agents.
DosageView
Schizophrenia and other psychoses:
- Adults and child over 12 years: Recommended starting dose is 2-5 mg b.i.d, increased by 5 mg daily after 1 week then at interval of 3 days, according to response.
- Children (6-12 years): Dosage should be adjusted to the weight of the child and severity of the symptoms. The starting dosage is 1 mg b.i.d. Dosage may be increased gradually until symptoms are controlled or until side effects become troublesome. While it is usually not necessary to exceed dosages of 15 mg daily.
- Elderly: Reduce initial dose by at least half
- Adult and child over 12 years: 1-2 mg b.i.d, increased if necessary to 6 mg daily.
- Child (3-5 years): 1 mg daily
- Child (6-12 years): Up to 4 mg daily in divided dose.
- Elderly: Reduce initial dose by at least half
- Adult: 2-4 mg daily in divided doses; max. 6 mg daily;
- Child 3-5 years: up to 1 mg daily, 6-12 years up to 4 mg daily.
Side effectsView
Common side effects are transient restlessness, dystonias or may resemble parkinsonism. Other CNS Reactions are drowsiness, dizziness, fatigue, blurred vision, seizures. Without these Peripheral oedema, blood dyscrasias, jaundice may occasionally occur. Tachycardia, constipation, urinary hesitancy and retention and hyperpyrexia have been reported very rarely.
ContraindicationsView
Do not use Trifluoperazine in comatose patients, or in those with existing blood dyscrasias or known liver damage, or in those hypersensitive to the active ingredient or related compounds.
PrecautionsView
Care should be taken when treating elderly patients, and initial dosage should be reduced. Such patients can be specially sensitive, particularly to extra pyramidal and hypotensive effects. Patients with cardiovascular disease including arrhythmias should also be treated with caution. Care should be taken in patients with angina pectoris.
InteractionsView
Trifluoperazine may diminish the effect of oral anticoagulants. Concomitant administration of propranolol with trifluoperazine results in increased plasma levels of both drugs. Antihypertensive effects of guanethidine and related compounds may be counteracted when phenothiazines are used concurrently. Potentiation may occur if antipsychotic drugs are combined with CNS depressants such as alcohol. hypnotics and anticonvulsant.
Pregnancy & lactationView
Pregnancy: Safety for the use of trifluoperazine during pregnancy has not been established. Therefore, it is not recommended that the drug be given to pregnant patients except when, in the judgement of the physician, it is essential. The potential benefits should clearly outweigh possible hazards. There are reported instances of prolonged jaundices, extrapyramidal signs, hyperreflexia or hypoflexia in newborn infants whose mother received phenothiazines.
Lactation: Adequate human data are not available in case of lactation.
Lactation: Adequate human data are not available in case of lactation.
Overdose effectsView
Signs and symptoms will be predominantly extrapyramidal; hypotension may occur. Treatment consists of gastric lavage together with supportive and symptomatic measures. Do not induce vomiting. Extra pyramidal symptoms may be treated with an anticholinergic, antiparkinsonism drug. Treat hypotension with fluid replacement; if severe or persistent. nor adrenaline may be considered. Adrenaline is contraindicated.

Indications
Severe anxiety disorders
Indication detailsView
Clozapine is indicated in-
- Schizophrenia in patients unresponsive to, or intolerant of, conventional antipsychotic drugs.
- Psychosis in Parkinson's disease.
Therapeutic classView
Atypical neuroleptic drugs
PharmacologyView
Clozapine is classified as an 'atypical' antipsychotic drug because of its profile of binding to dopamine receptors and its effects on various dopamine-mediated behaviors differ from those exhibited by other typical antipsychotic drug products. In particular, although Clozapine does interfere with the binding of dopamine at D1, D2, D3 and D5 receptors, and has a high affinity for the D4 receptor. This evidence, consistent with the view that Clozapine is preferentially more active at limbic than at striatal dopamine receptors. This may explain the relative freedom of Clozapine from extrapyramidal side effects. Clozapine also acts as an antagonist at adrenergic, cholinergic, histaminergic and serotonergic receptors.
DosageView
Schizophrenia: Adult over 16 years, 12.5 mg once or twice (elderly 12.5 mg once) on first day then 25-50 mg (elderly 25-37.5 mg) on second day then increased gradually (if well tolerated) in steps of 25-50 mg daily (elderly max. increment 25 mg daily) over 14-21 days up to 300 mg daily in divided doses (larger dose at night, up to 200 mg daily may be taken as a single dose at bedtime); if necessary may be further increased in steps of 50-100 mg once (preferably) or twice weekly; usual dose 200-450 mg daily (max. 900 mg daily)
Psychosis in Parkinson's disease: Adult over 16 years, 12.5 mg at bedtime then increased according to response in steps of 12.5 mg up to twice weekly; usual dose range 25-37.5 mg at bedtime, usual maximum 50 mg daily; exceptionally, dose may be increased further in steps of 12.5 mg weekly to maximum 100 mg daily in 1-2 divided doses.
Psychosis in Parkinson's disease: Adult over 16 years, 12.5 mg at bedtime then increased according to response in steps of 12.5 mg up to twice weekly; usual dose range 25-37.5 mg at bedtime, usual maximum 50 mg daily; exceptionally, dose may be increased further in steps of 12.5 mg weekly to maximum 100 mg daily in 1-2 divided doses.
Side effectsView
Common side effects are constipation, dizziness or lightheadedness (mild), drowsiness, headache (mild), increased watering of mouth, nausea or vomiting, unusual weight gain. Less common side effects include abdominal discomfort or heartburn, dryness of mouth.
ContraindicationsView
Severe cardiac disorders (e.g. myocarditis); renal impairment (avoid if creatinine clearance less than 10 ml/minute); history of neutropenia or agranulocytosis; bone-marrow disorders; paralytic ileus; alcoholic and toxic psychoses; history of circulatory collapse; drug intoxication; coma or severe CNS depression; uncontrolled epilepsy; breast-feeding.
PrecautionsView
Medication should not be stopped abruptly; should be tapered off over 1-2 weeks. If conditions warrant abrupt discontinuation (leukopenia, myocarditis, cardiomyopathy), monitor patient for psychosis and cholinergic rebound (headache, nausea, vomiting, diarrhea). Elderly patients are more susceptible to adverse effects (including agranulocytosis, cardiovascular, anticholinergic, and tardive dyskinesia). Significant risk of agranulocytosis, potentially life-threatening. WBC testing should occur weekly for the first 6 months of therapy; thereafter, if acceptable WBC counts are maintained (WBC 3000/mm3, ANC 1500/mm3) then WBC counts can be monitored every other week. WBCs must be monitored weekly for the first 4 weeks after therapy discontinuation. Use with caution in patients receiving other marrow suppressive agents. Eosinophilia has been reported to occur with Clozapine and may require temporary or permanent interruption of therapy.
Cognitive and/or motor impairment (sedation) is common with Clozapine, resulting in impaired performance of tasks requiring alertness (eg, operating machinery or driving). Use with caution in patients at risk of seizures, including those with a history of seizures, head trauma, brain damage, alcoholism, or concurrent therapy with medications which may lower seizure threshold. Has been associated with benign, self-limiting fever (<100.4°F, usually within first 3 weeks). However, dozapine may also be associated with severe febrile reactions, including neuroleptic malignant syndrome (NMS). Clozapine's potential for extrapyramidal symptoms appear to be extremely low.
May cause anticholinergic effects; should be used with caution in patients with urinary retention, benign prostatic hyperplasia, narrow-angle glaucoma, xerostomia, visual problems, constipation, or history of bowel obstruction. May cause hyperglycemia; in some cases may be extreme and associated with ketoacidosis, hyperosmolar coma, or death. Use with caution in patients with diabetes or other disorders of glucose regulation; monitor for worsening of glucose control. Use with caution in patients with hepatic disease or impairment; hepatitis has been reported as a consequence of therapy.
May cause orthostatic hypotension and tachycardia; should be used with caution in patients at risk of hypotension or in patients where transient hypotensive episodes would be poorly tolerated (cardiovascular disease or cerebrovascular disease). Concurrent use of psychotropics and benzodiazepines may increase the risk of severe cardiopulmonary reactions.
Myocarditis, pericarditis, pericardial effusion, cardiomyopathy, and CHF have also been associated with clozapine. Fatalities due to myocarditis have been reported; highest risk in the first month of therapy, however, later cases also reported. Myocarditis or cardiomyopathy should be considered in patients who present with signs/symptoms of heart failure (dyspnea, fatigue, orthopnea, paroxysmal nocturnal dyspnea, peripheral edema), chest pain, palpitations, new electrocardiographic abnormalities (arrhythmias, ST-T wave abnormalities), or unexplained fever. Patients with tachycardia during the first month of therapy should be closely monitored for other signs of myocarditis. Discontinue clozapine if myocarditis is suspected; do not rechallenge in patients with clozapine-related myocarditis. The reported rate of cardiomyopathy in clozapine treated patients is similar to that in the general population. The majority of patients were over 50 years of age and were taking clozapine for >6 months. Clozapine should be discontinued in patients with confirmed cardiomyopathy unless benefit clearly outweighs risk. Rare cases of thromboembolism, including pulmonary embolism and stroke resulting in fatalities, have been associated with clozapine.

InteractionsView
Myelosuppression may be aggravated with concomitant use of myelosuppressants. Clozapine may interact with other CNS active drugs or alcohol. Orthostatic hypotension may occur with benzodiazepine usage or other psychotropics. Since Clozapine is highly bound to proteins. It may be displaced by other drugs, which are also highly protein bound. Conversely, Clozapine may also displace protein bound drugs (e.g. warfarin, digoxin). Cimetidine may decrease plasma Clozapine levels.
Although concomitant administration of Carbamazepine and Clozapine is not recommended, it should be noted that discontinuation of concomitant Carbamazepine may result in an increase in plasma Clozapine levels. A reduced Clozapine dosage should be used when it is combined with drugs like fluvoxamine, paroxetine and sertraline. The action of hypotensive drugs may be potentiated. Other anticholinergic drug action may also be increased. Administration of adrenaline should generally be avoided due to possibility of reversal of adrenaline effect due to alpha adrenergic blockade by Clozapine. Concomitant use of Clozapine with other drugs metabolized by cytochrome P450 2D6 (such as phenothiazines, antidepressants, propafenone, flecainide and encainide) or those that inhibit this enzyme such as quinidine; require lower doses of either Clozapine or the other drugs.

Pregnancy & lactationView
There are no adequate studies of Clozapine in pregnant women. Studies in animals suggest no important effects on the fetus. Clozapine can be used in pregnancy if the physician feels that it is necessary. Animal studies suggest that Clozapine is secreted in breast milk. Therefore, women taking Clozapine should not nurse their infants.
Overdose effectsView
The most commonly reported signs and symptoms associated with Clozapine overdose are: altered states of consciousness, including drowsiness, delirium and coma; tachycardia; hypotension; respiratory depression or failure; hypersalivation. Aspiration pneumonia and cardiac arrhythmias have also been reported. Seizures have occurred in a minority of reported cases. Fatal overdoses have been reported with Clozapine, generally at doses above 2500 mg. There have also been reports of patients recovering from overdoses well in excess of 4 gm.
Management of Overdose: Should be established and maintained an airway; should be ensured adequate oxygenation and ventilation. Activated charcoal, which may be used with sorbitol, may be as or more effective than emesis or lavage, and should be considered in treating overdosage. Cardiac and vital signs monitoring is recommended along with general symptomatic and supportive measures. Additional surveillance should be continued for several days because of the risk of delayed effects. Avoid epinephrine and derivatives when treating hypotension, and quinidine and procainamide when treating cardiac arrhythmia. There are no specific antidotes for Clozapine. Forced diuresis, dialysis, hemoperfusion and exchange transfusion are unlikely to be of benefit. ln managing overdosage, the physician should consider the possibility of multiple drug involvement.

Myocarditis or cardiomyopathy should be considered in patients who present with signs/symptoms of heart failure (dyspnea, fatigue, orthopnea, paroxysmal nocturnal dyspnea, peripheral edema), chest pain, palpitations, new electrocardiographic abnormalities (arrhythmias, ST-T wave abnormalities), or unexplained fever. Patients with tachycardia during the first month of therapy should be closely monitored for other signs of myocarditis. Discontinue clozapine if myocarditis is suspected; do not rechallenge in patients with clozapine-related myocarditis. The reported rate of cardiomyopathy in clozapine treated patients is similar to that in the general population. The majority of patients were over 50 years of age and were taking clozapine for >6 months. Clozapine should be discontinued in patients with confirmed cardiomyopathy unless benefit clearly outweighs risk. Rare cases of thromboembolism, including pulmonary embolism and stroke resulting in fatalities, have been associated with clozapine.
InteractionsView
Myelosuppression may be aggravated with concomitant use of myelosuppressants. Clozapine may interact with other CNS active drugs or alcohol. Orthostatic hypotension may occur with benzodiazepine usage or other psychotropics. Since Clozapine is highly bound to proteins. It may be displaced by other drugs, which are also highly protein bound. Conversely, Clozapine may also displace protein bound drugs (e.g. warfarin, digoxin). Cimetidine may decrease plasma Clozapine levels.
Although concomitant administration of Carbamazepine and Clozapine is not recommended, it should be noted that discontinuation of concomitant Carbamazepine may result in an increase in plasma Clozapine levels. A reduced Clozapine dosage should be used when it is combined with drugs like fluvoxamine, paroxetine and sertraline. The action of hypotensive drugs may be potentiated. Other anticholinergic drug action may also be increased. Administration of adrenaline should generally be avoided due to possibility of reversal of adrenaline effect due to alpha adrenergic blockade by Clozapine. Concomitant use of Clozapine with other drugs metabolized by cytochrome P450 2D6 (such as phenothiazines, antidepressants, propafenone, flecainide and encainide) or those that inhibit this enzyme such as quinidine; require lower doses of either Clozapine or the other drugs.

Pregnancy & lactationView
There are no adequate studies of Clozapine in pregnant women. Studies in animals suggest no important effects on the fetus. Clozapine can be used in pregnancy if the physician feels that it is necessary. Animal studies suggest that Clozapine is secreted in breast milk. Therefore, women taking Clozapine should not nurse their infants.
Overdose effectsView
The most commonly reported signs and symptoms associated with Clozapine overdose are: altered states of consciousness, including drowsiness, delirium and coma; tachycardia; hypotension; respiratory depression or failure; hypersalivation. Aspiration pneumonia and cardiac arrhythmias have also been reported. Seizures have occurred in a minority of reported cases. Fatal overdoses have been reported with Clozapine, generally at doses above 2500 mg. There have also been reports of patients recovering from overdoses well in excess of 4 gm.
Management of Overdose: Should be established and maintained an airway; should be ensured adequate oxygenation and ventilation. Activated charcoal, which may be used with sorbitol, may be as or more effective than emesis or lavage, and should be considered in treating overdosage. Cardiac and vital signs monitoring is recommended along with general symptomatic and supportive measures. Additional surveillance should be continued for several days because of the risk of delayed effects. Avoid epinephrine and derivatives when treating hypotension, and quinidine and procainamide when treating cardiac arrhythmia. There are no specific antidotes for Clozapine. Forced diuresis, dialysis, hemoperfusion and exchange transfusion are unlikely to be of benefit. ln managing overdosage, the physician should consider the possibility of multiple drug involvement.

Aripiprazole
Sizopra
Aripiprazole
Indications
Schizophrenia
Indication detailsView
Aripiprazole is indicated for-
- Schizophrenia
- Schizoaffective disorder
- Acute manic and mixed episodes associated with Bipolar I Disorder
- Maintaining efficacy in patients with Bipolar I Disorder who are stabilized
Therapeutic classView
Atypical neuroleptic drugs
PharmacologyView
Aripiprazole is an atypical antipsychotic that has both dopamine and serotonin receptors activity. It is a partial agonist of dopamine D2 receptors that relieves the symptoms of schizophrenia. It is characterized as a dopamine system stabilizer. It is a potent partial agonist at serotonin 5-HT1A receptors and antagonist at 5-HT2A receptors. This is associated with improvement of depressive, cognitive and negative symptoms.
DosageView
For Schizophrenia: 10 to 15 mg, once daily, without regard to food. Dose increment should not be made before 2 weeks, the time needed to achieve steady state.
For Bipolar mania: 30 mg, once daily, without regard to food.
For Bipolar mania: 30 mg, once daily, without regard to food.
Side effectsView
Headache, constipation, asthenia, nausea, dyspepsia, vomiting, coughing, abdominal pain.
ContraindicationsView
Aripiprazole is contraindicated in patients who are hypersensitive to it or to any component of this product.
PrecautionsView
Aripiprazole may be associated with orthostatic hypotension (orthostatic lightheadedness).
Aripiprazole should be used with caution in patients with known cardiovascular disease (myocardial infarction or ischaemic heart disease, heart failure or conduction abnormalities), cerebrovascular disease, or conditions that would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medications).
Seizures occurred in aripiprazole-treated patients. As with other antipsychotic drugs, aripiprazole should be used cautiously in patients with Alzheimer's dementia.
Aripiprazole is not approved for the treatment of patients with dementia-related psychosis.

Aripiprazole is not approved for the treatment of patients with dementia-related psychosis.
InteractionsView
Caution should be exercised when aripipazole is taken in combination with other centrally acting drugs and alcohol. Carbamazepine could cause an increase in aripiprazole clearance and lower blood levels. Ketoconazole, quinidine, fluoxetine or paroxetine can inhibit aripiprazole elimination and cause increased blood levels.
Pregnancy & lactationView
Aripiprazole should not be used in pregnancy as no human trial is performed. Patients should be advised not to breast feed an infant if they are taking aripiprazole.
Overdose effectsView
Aripiprazole at doses up to 1080 mg causes no fatalities. The signs and symptoms observed with aripiprazole overdose included nausea, vomiting, asthenia, diarrhea, and somnolence.
