Drugs for Osteoarthritis, Drugs used for Rheumatoid Arthritis, Non-steroidal Anti-inflammatory Drugs (NSAIDs)

Dexibuprofen (S (+)-ibuprofen) is considered as the pharmacologically active enantiomer of racemic ibuprofen. Like racemic ibuprofen, Dexibuprofen is a non-steroidal anti-inflammatory drug with analgesic action. Like ibuprofen, Dexibuprofen acts by inhibiting prostaglandin synthesis.

Pharmacokinetics: Dexibuprofen is absorbed primarily from the small intestine. After metabolic transformation in the liver (hydroxylation, carboxylation) the pharmacologically inactive metabolites are completely excreted, mainly by the kidneys (90%), but also in the bile. The elimination half-life is 1.8-3.5 hours; the plasma protein binding is about 99%. Maximum plasma levels are reached about 2 hours after oral administration. The administration of dexibuprofen with a meal delays the time to reach maximum concentrations (from 2.1 hours after fasting conditions to 2.8 hours after non-fasting conditions) and decreases the maximum plasma concentrations (from 20.6 to 18.1 mcg/ml, which is of no clinical relevance), but has no effect on the extent of absorption.

The dosage must be adjusted to the seriousness of the syndrome and the complaints of the patient. During chronic pain, the dosage must be adapted to the lowest effective dose.

The recommended dosage: 600-900 mg Dexibuprofen per day, at 2-3 divided doses. The dosage can be raised temporarily up to 1200 mg Dexibuprofen per day in patients with acute disorders or exacerbations. The maximum daily dose is 1200 mg.

At dysmenorrhea: A dosage of 600 up to 900 mg Dexibuprofen per day, at a divided dose.

Clinical experience has shown that adverse effects of Dexibuprofen are similar to those of racemic ibuprofen. Common side-effects are dyspepsia, diarrhea, fatigue, and headache, nausea, vomiting, abdominal pain, hypersensitivity reactions - bleeding, ulcer.

Dexibuprofen is contraindicated in patients with previous history of hypersensitivity to Dexibuprofen, or another NSAID, or any other component of the product. Patients, who experience attack of asthma, arouse bronchospasm, acute rhinitis, urticaria or edema after use of similar drugs (e.g. aspirin or other NSAID's). It is also contraindicated in patients with active or suspected hemorrhage, Crohn's disease or ulcerative colitis, patients with serious heart diseases, kidney function impairment (GFR <30ml/min), and liver function impairment.

Dexibuprofen should be used with particular caution in patients with bronchial asthma or other chronic diseases of the pulmonary tract as well as in persons prone to allergy. The drug should be used in patients with hepatic, renal or cardiac insufficiency and with hypertension not responding to any treatment. Consultation with a doctor is recommended for patients with systemic lupus or with other autoimmunological disease before beginning therapy using the drug. Dexibuprofen should be used with extreme cautions in active and suspected hemorrhagic conditions such as gastro-duodenal ulcers, ulcerative colitis, Crohn's disease, alcoholism. Allergic reactions to the drug may appear even for the first-time user and in such case, it should immediately be stopped.

The reported drug interactions of Dexibuprofen are similar to that of racemic mixture of ibuprofen. Drug interactions is noticed with simultaneous use of anticoagulant, hydantoine and sulfonamide, ticlopidine, lithium, other NSAID's, ACE inhibitors, beta blockers, cyclosporine, tacrolimus, corticosteroids, digoxin, methotrexate, pentoxyfiline, phenytoine, probenecid, sulfinpyrazon, sulfonylurea, thiazide and thiazide type diuretics, and zidovudine.

Pregnancy: Although no teratogennic impact has been observed in the animal-experimental research with dexibuprofen or ibuprofen, the use should be avoided during the pregnancy. However, animal reproduction studies are not always predictive of human response. Because of the known effects of nonsteroidal anti-inflammatory drugs on the fetal cardiovascular system (closure of ductus arteriosus), use during late pregnancy should be avoided.

Lactation: Studies at people have shown that racimic ibuprofen proceed in small to negligible degree in mother milk. So, Dexibuprofen should be used with cautions in nursing mothers.

Hepatic impairment: Patients with mild to moderate liver function impairments must start with low amounts, and must closely be monitored. Dexibuprofen should not be used in patients with serious liver function impairments.

Renal impairment: The start amount must be reduced at patients with mild to moderate kidney function impairments. Dexibuprofen cannot be used patients with serious kidney function impairments.

Children Dose: Although Dexibuprofen is not licensed for use in children under 18 years of age in the UK, some countries permit such use. For example, in Switzerland, Dexibuprofen has been given to children aged 6 years and over at a dose of 10 to 15 mg/kg daily in 2-4 divided doses.

For elderly people: Lowest effective dose is recommended. The dosage can be raised to adult dosage if well tolerated.

Dexibuprofen has low acute toxicities. Symptoms of toxicity occur at doses between 80 and 100 mg/kg body weight. Mild symptoms are abdominal pain, nausea, vomiting, lethargy, headache, tinnitus and ataxia. Moderate to serious symptoms, such as flatulence, hypotension, hypothermia, metabolic acidosis, reduced kidney function, coma, and apnoea. The treatment must be symptomatic: there is no specific antidote. In case of large quantities of Dexibuprofen, activated charcoal should be administered. Vomiting can be induced only when life-threatening quantities of the substance ingested and the procedure can be carried out within 60 minutes after ingestion. Dialysis and hemodialysis are of little value as Dexibuprofen binds strongly to plasma protein.

Do not store above 30°C. Keep away from light and out of the reach of children

Etoricoxib is indicated for the symptomatic relief of-

• Osteoarthritis (OA)
• Rheumatoid arthritis (RA)
• Ankylosing spondylitis, and
• The pain and signs of inflammation associated with acute gouty arthritis.
• For the short-term treatment of moderate pain associated with dental surgery.

Non-steroidal Anti-inflammatory Drugs (NSAIDs)

Etoricoxib is a potent, orally active cyclooxygenase-2 (COX-2) specific inhibitor within, and significantly above, the clinical dose range. Two isoforms of cyclooxygenase have been identified: cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2). COX-1 is responsible for prostaglandin-mediated normal physiologic functions such as gastric cytoprotection and platelet aggregation. Inhibition of COX-1 by nonselective NSAIDs has been associated with gastric damage and inhibition of platelet aggregation. COX-2 has been shown to be primarily responsible for the synthesis of prostanoid mediators of pain, inflammation, and fever. Selective inhibition of COX-2 by etoricoxib (within the clinical dose range) decreases these clinical signs and symptoms with decreased potential for Gl toxicity and effects on platelet aggregation. Etoricoxib produced dose-dependent inhibition of COX-2 without inhibition of COX-1 at doses up to 150 mg daily. Etoricoxib did not inhibit gastric prostaglandin synthesis.

Adult and adolescent over 16 years:

• Osteoarthritis: The recommended dose is 30 mg once daily. In some patients with insufficient relief from symptoms, an increased dose of 60 mg once daily may increase efficacy.
• Rheumatoid arthritis: The recommended dose is 90 mg once daily.
• Ankylosing spondylitis: The recommended dose is 90 mg once daily.
• Acute gouty arthritis: The recommended dose is 120 mg once daily. In clinical trials for acute gouty arthritis, Etoricoxib was given for 8 days.
• Postoperative dental surgery pain: The recommended dose is 90 mg once daily, limited to a maximum of 3 days.

Some patients may require additional postoperative analgesia. As the cardiovascular risks of Etoricoxib may increase with dose and duration of exposure, the shortest duration possible and the lowest effective daily dose should be used. The patient's need for symptomatic relief and response to therapy should be re-evaluated periodically, especially in patients with osteoarthritis.

Side-effects may include palpitation, fatigue, influenza-like symptoms, ecchymosis; less commonly dry mouth, taste disturbance, mouth ulcer, appetite and weight change, atrial fibrillation, transient ischaemic attack, chest pain, flushing, cough, dyspnoea, epistaxis, anxiety, mental acuity impaired, paraesthesia, electrolyte disturbance, myalgia and arthralgia; very rarely confusion and hallucinations.

With medicine:

• Oral anticoagulants: In subjects stabilized on chronic warfarin therapy, the administration of Etoricoxib was associated with an increase in prothrombin time.
• Diuretics, ACE inhibitors and Angiotensin II Antagonists: NSAIDs may reduce the effect of diuretics and other antihypertensive drugs.
• Acetylsalicylic Acid: Etoricoxib can be used concomitantly with acetylsalicylic acid at doses used for cardiovascular prophylaxis (low-dose acetylsalicylic acid).
• Ciclosporin and tacrolimus: Although this interaction has not been studied with Etoricoxib, coadministration of ciclosporin or tacrolimus with any NSAID may increase the nephrotoxic effect of ciclosporin or tacrolimus.
• Lithium: NSAIDs decrease lithium renal excretion and therefore increase lithium plasma levels.

With food & others: Take without regards to meals.

The use of Etoricoxib, as with any drug substance known to inhibit COX-2, is not recommended in women attempting to conceive. It is not known whether Etoricoxib is excreted in human milk. Etoricoxib is excreted in the milk of lactating rats. Women who use Etoricoxib must not breastfeed.

Administration of single doses of Etoricoxib up to 500 mg and multiple doses up to 150 mg/day for 21 days did not result in significant toxicity. In the event of overdose, it is reasonable to employ the usual supportive measures, e.g., remove unabsorbed material from the Gl tract, employ clinical monitoring, and institute supportive therapy, if required.

Store at a temperature of below 30°C, protect from light & moisture. Keep out of reach of children.

Spirulina is used for the treatment and prevention of malnutrition, diabetes, arthritis, asthma, hyperglycemia, anemia, allergic rhinitis and to enhance immunity. Spirulina helps to maintain healthy eyes and skin.

Herbal and Nutraceuticals

Spirulina has such positive TTutritionafcontent that it is called the world's richest whole-food which can be found naturally. It is very high in protein with low calorie content (only coming in at 2.9 calories per gram) using this as a supplement for protein specifically this is less than % the amount of calories in protein per gram, Spirulina is the highest source of B-12, essential for healthy nerves and tissue, especially for vegetarians. Due to large amount of iron in spirulina, it helps to promote the creation of new red blood cells too. Not only does spirulina contain high protein content within it, but it also has nutrients in it which increase the body's ability to absorb protein, This means that it even makes any other protein being consumed by the person more effective than if they had just consumed the protein alone. ln this way, spirulina may even be a better source of protein than most meal. Spirulina contains a concentration of very single amino acid as well. These are amino acids that the body cannot survive without, but we cannot produce ourselves which means we have to get them through other dietary means. Spirulina contains approximately 100 nutrients and minerals. Furthermore it has fatty acids that help reduce bad cholesterol in our body and antioxidants that help strengthen our immune system, fight free radicals and slow down the aging process. It is recommended to people whose intake of nutritious food is anadequate.

How does it work-

• About 60% of spirulina dry weight is protein which is essential for growth and cell regeneration. Besides this it had sufficient vitamins and minerals within, With its high digestibility, spirulina has proven to fight malnutrition in impoverished communities by helping the body absorb nutrients when it has lost its ability to absorb normal forms of food.
• Every 10 grams of spirulina can supply up to 70% of the minimum daily requirements for iron. Being rich in iron, magnesium and trace minerals spirulina is easier to absorb than iron supplements to fight anemia effectively.
• Spirulina is rich in gamma-linolenic acid or GLA, a compound found in breast milk that helps develop healthier babies.
• Another health benefit of spirulina is that it stimulates beneficial flora like lactobacillus and bifidobacterial in our digestive tract to promote healthy digestion and proper bowel function. It acts as a natural cleanser by eliminating mercury and other deadly toxins commonly ingested by the body.

2 to 4 capsules daily or as advised by the physician.

Spirulina is generally well tolerated. Occasional diarrhea, gastrointestinal discomfort, such as nausea have been reported. Also there are few reports of allergic reactions to spirulina containing supplements.

Spirulina is contraindicated in those who are hypersensitive to any component of this product.

Before taking spirulina pregnant or breast-feeding women should talk to the physician.

There are no reports suggesting that spirulina interacts with any conventional medication.

Before taking spirulina pregnant or breast-feeding women should talk to the physician.

Store in a cool and dry place. Keep away from direct sunlight. Keep out of reach of the children.

This tablet is indicated for-

• Reduction of neurological damage & accelerates recovery after cerebral stroke
• Minor age-related neurological disorders
• Some visual disorders related to the circulation
• Some disorders of the inner ear related to circulation (hearing loss, dizziness, buzzing sounds in the ear).

Cerebral vasodilator & Neurosensory oxygenator drugs

Almitrine Bismesylate & Raubasine combines raubasine, a vasodilator; and almitrine, a respiratory stimulant. Raubasine has a adrenolytic activity which is predominantly related to a post-synaptic blocking effect. Furthermore, under conditions of cerebral hypoxia, almitrine causes an increase in the partial pressure of oxygen in arterial blood (Pa0₂); almitrine causes an increase in the Pa0₂ and an increase in the oxygen saturation in arterial blood (Sa0₂), without modifying ventilatory parameters.

1 tablet once or twice daily (taken separately, several hours apart), without exceeding 2 tablets per day. Or, as directed by the registered physicians.

Weight loss, nausea, sensations of heaviness or burning in the stomach, gastrointestinal disorders, diarrhoea or constipation, insomnia, drowsiness, agitation, anxiety, dizziness, palpitations.

This tablet is contraindicated in patients with hypersensitivity to any of the ingredients of it or severe hepatic impairment.

Due to the presence of lactose, this drug should not be used in the case of galactosemia, of glucose and galactose malabsorption syndrome or of lactose deficiency (rare metabolic diseases). Do not exceed the recommended dose.

Do not associate with MAO-l (monoamine oxidase inhibitor), Not to be used concurrently with other almitrine-containing preparations.

It is not recommended in pregnancy. It should be used with caution only when the expected benefit to the mother is greater than the possible risk to the fetus.

Signs include tachycardia, arterial hypotension, polypnoea and respiratory alkalosis.

Store at a cool and dry place, protected from light and moisture. Keep out of reach of children.

Benzyl Benzoate is indicated for scabies

Parasiticidal preparations, Topical Antifungal preparations

Benzyl benzoate is an acaricide that is used in the treatment of scabies. Benzyl benzoate exerts toxic effects on the nervous system of the parasite, resulting in its death. It is also toxic to mite ova, though its exact mechanism of action is unknown. In vitro, benzyl benzoate has been found to kill the Sarcoptes mite within 5 minutes.

Adult: Apply 3 times at 12 hourly intervals over the whole body, wash-off 12 hr after the last application.

Irritant to eyes and mucous membranes, allergic dermatitis reactions, drying effects in the elderly.

Broken or irritated skin; neonates; pregnancy.

Anti-platelet drugs

Clopidogrel is a prodrug. It inhibits platelet activation and aggregation through the irreversible binding of its active metabolite to the P2Y12 class of ADP receptors on platelets. Dose-dependent inhibition of platelet aggregation can be seen at 2 hours after single oral doses. Repeated doses of 75 mg per day inhibit ADP-induced platelet aggregation on the first day, and inhibition reaches steady state between Day 3 and Day 7.

Aspirin inhibits platelet aggregation by irreversible inhibition of platelet cyclooxygenase and thus inhibiting the generation of thromboxane A2 a powerful inducer of platelet aggregation and vasoconstriction.

The recommended oral dose is one tablet daily.

This combination is generally well tolerated.

This combination is contraindicated in the following conditions: Hypersensitivity to the drug substance or any component of the product. Active pathological bleeding such as peptic ulcer or intracranial hemorrhage.

Oral anticoagulants, NSAIDs, Metamizole, SSRIs, CYP2C19 inhibitors increase the risk of bleeding. It shows interaction with Tonofovir, Valproic acid, Varicella vaccine, Acetazolamide and Nicorandil.

There are no adequate and well-controlled studies in pregnant women. It should be used during first and second trimesters of pregnancy only if clearly needed. It is contraindicated during the third trimester of pregnancy. It is unknown whether Clopidogrel is excreted in human breast milk but Aspirin is known to be excreted in human milk. This Drug should be discontinued during the breast feeding.

It should not be given to children, particularly those under 12 years, unless the expected benefits outweight the possible risks. Aspirin may be a contributory factor in the causation of Reye’s syndrome in some children.

Clopidogrel overdose may lead to bleeding complications. Based on biological plausibility, platelet transfusion may restore clotting ability. In moderate aspirin intoxication dizziness, headache, tinnitus, confusion, and gastrointestinal symptoms may occur which can be treated by inducing vomiting followed by gastric lavage if needed. In severe Aspirin intoxication respiratory alkalosis respiratory acidosis, metabolic acidosis, hyperthermia, perspiration, dehydration can occur. It can be treated with haemodialysis and other symptomatic treatment.

Keep in a cool & dry place (below 30o C), protected from light & moisture. Keep out of the reach of children.

Vitamin-C Preparations

vitamin C, the water-soluble vitamin, is readily absorbed from the gastrointestinal tract and is widely distributed in the body tissues. It is believed to be involved in biological oxidations and reductions used in cellular respiration. It is essential for the synthesis of collagen and intracellular material. Vitamin C deficiency develops when the dietary intake is inadequate and when increased demand is not fulfilled. Deficiency leads to the development of well defined syndrome known as scurvy, which is characterized by capillary fragility, bleeding (especially from small blood vessels and the gums), anaemia, cartilage and bone lesions and slow healing of wounds.

Oral administration-

• For the prevention of scurvy: 1 tablet daily
• For the treatment of scurvy: 1-2 tablets daily; but dose may be increased depending on the severity of the condition.
• For the reduction of risk of stroke in the elderly: 1-2 tablets daily.
• In other cases: 1 tablet daily or as directed by the physician.
• Maximum safe dose is 2000 mg daily in divided doses.

Parenteral administration-

• Vitamin C is usually administered orally. When oral administration is not feasible or when malabsorption is suspected, the drug may be administered IM, IV, or subcutaneously. When given parenterally, utilization of the vitamin reportedly is best after IM administration and that is the preferred parenteral route.
• For intravenous injection, dilution into a large volume parenteral such as Normal Saline, Water for Injection, or Glucose is recommended to minimize the adverse reactions associated with intravenous injection.
• The average protective dose of vitamin C for adults is 70 to 150 mg daily. In the presence of scurvy, doses of 300 mg to 1 g daily are recommended. However, as much as 6 g has been administered parenterally to normal adults without evidence of toxicity.
• To enhance wound healing, doses of 300 to 500 mg daily for a week or ten days both preoperatively and postoperatively are generally considered adequate, although considerably larger amounts have been recommended. In the treatment of burns, doses are governed by the extent of tissue injury. For severe burns, daily doses of 1 to 2 g are recommended. In other conditions in which the need for vitamin C is increased, three to five times the daily optimum allowances appear to be adequate.
• Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever the solution and container permit.

Vitamin C has little toxicity and only mega-doses of vitamin C may cause diarrhoea, abdominal bloating, iron over-absorption that is harmful in patients with thalassaemia, sideroblastic anemia, and haemochromatosis; hyperoxaluria, hyperuricosuria, and hemolysis in patients with glucose-6 phosphate dehydrogenase deficiency. A pregnant woman taking more than 5 gm/day may suffer fetal abortion.

Ingestion of megadose (more than 1000 mg daily) of vitamin C during pregnancy has resulted in scurvy in neonates. Vitamin C in mega-doses has been contraindicated for patients with hyperoxaluria. Vitamin C itself is a reactive substance in the redox system and can give rise to false positive reactions in certain analytical tests for glucose, uric acid, creatine and occult blood.

Potentially hazardous interactions: Ascorbic acid is incompatible in solution with aminophylline, bleomycin, erythromycin, lactobionate, nafcillin, nitrofurantoin sodium, conjugated oestrogen, sodium bicarbonate, sulphafurazole diethanolamine, chloramphenicol sodium succinate, chlorthiazide sodium and hydrocortisone sodium succinate.

Useful interactions: Ascorbic acid increases the apparent half-life of paracetamol and enhances iron absorption from the gastrointestinal tract.

The drug is safe in normal doses in pregnant women, but a daily intake of 5 gm or more is reported to have caused abortion. The drug may be taken safely during lactation.

Should be stored in a dry place below 30˚C.

Ferrous Sulfate is indicated in the treatment and prevention of iron deficiency anaemia and anaemia of pregnancy where routine administration of iron is necessary.

Oral Iron preparations

Adult-

• Initial therapeutic dose: 3-4½ teaspoonful daily in divided doses or as prescribed by the physician.
• Maintenance dose: 1½ teaspoonful daily, but if needed up to 1.8g (9 teaspoonful) daily can be given.

Children-

• Under 1 year: ¼ th teaspoonful thrice daily or as directed by physician
• 1-5 years: 1 teaspoonful thrice daily

Mix with water or fruit juice to avoid temporary staining of teeth. Do not mix with milk.

Therapeutic doses of iron may cause gastrointestinal symptoms like diarrhoea, nausea and vomiting. Although iron is better absorbed between meals, side effects can be reduced by taking it with or immediately after food. Continuous administration may sometimes cause constipation. Iron containing liquid medication may cause temporary staining of teeth (this is less likely when diluted).

Iron therapy is contraindicated in haemachromatosis and haemosiderosis.It should not be given to patients receiving repeated blood transfusion or with anaemia not produced by iron deficiency.

Should be administered with caution when given to patients with iron storage or iron absorption disease, haemoglobinopathies or existing gastrointestinal disease.

Absorption of iron salt and Tetracycline is diminished when taken concomitantly by mouth. If treatment with both drugs is required iron salt should be given 3 hours before or 2 hours after Tetracycline. Absorption of iron is also decreased in the presence of antacids or when taken with tea.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.

Respiratory corticosteroids

Beclomethasone dipropionate given by inhalation at recommended doses has a glucocorticoid antiinflammatory action within the lungs, resulting in reduced symptoms and exacerbations of asthma with less adverse effects than when corticosteroids are administered systemically.

Formoterol is a selective β2-adrenergic agonist that produces relaxation of bronchial smooth muscle in patients with reversible airways obstruction. The bronchodilating effect sets in rapidly, within 1-3 minutes after inhalation, and has a duration of 12 hours after a single dose.

Adults 18 years and above: One or two inhalations twice daily. The maximum daily dose is 4 inhalations.

Children and adolescents under 18 years: The safety and efficacy in children and adolescents under 18 years of age have not been established yet. No data are available with the drug in children under 12 years of age. Therefore the drug is not recommended for children and adolescents under 18 years until further data become available.

Using an Inhaler seems simple, but most patients do not know how to use it in the right way. If the Inhaler is used in the wrong way, less medicine can reach the lungs. Correct and regular use of the Inhaler will prevent or lessen the severity of asthma attacks.

Following simple steps can help to use Inhaler effectively (According to "National Asthma Guidelines for Medical Practitioners" published by Asthma Association):

1. Take off the cap.
2. Shake the inhaler (at least six times) vigorously before each use.
3. If the inhaler is new or if it has not been used for a week or more, shake it well and release one puff into the air to make sure that it works.
4. Breathe out as full as comfortably possible & hold the inhaler upright.
5. Place the actuator into mouth between the teeth and close lips around the mouthpiece.
6. While breathing deeply and slowly through the mouth, press down firmly add fully on the canister to release medicine.
7. Remove the inhaler from mouth. Continue holding breath for at least for 10 seconds or as long as it is comfortable.
8. If doctor has prescribed more than one inhalation per treatment, wait 1 minute between puffs (inhalations). Shake the inhaler well and repeat steps 4 to 7.
9. After use, replace the cap on the mouthpiece. After each treatment, rinse mouth with water.
10. Check your technique in front of a mirror from time to time, if you see a white mist during the inhalation, you may not have closed your lips properly around mouthpiece, or you may not be breathing in as you press the can. This indicates failure of technique. If this happens, repeat the procedure from step 4 carefully.

Instructions for Cleaning Inhaler: Clean your Inhaler at least once a week. Remove canister and rinse the plastic actuator and cap in warm water but do not put the metal canister into water. Dry the actuator and cap thoroughly and gently replace the metal canister into the actuator with a twisting motion. Put the cap on the mouthpiece.

As the drug contains beclometasone dipropionate and formoterol fumarate dihydrate, the type and severity of adverse reactions associated with each of the compounds may be expected. Common side effects are pharyngitis, oral candidiasis, headache, dysphonia.

Contraindicated in patients with hypersensitivity to any component of this product.

The drug should be used with caution (which may include monitoring) in patients with cardiac arrhythmias, especially third degree atrioventricular block and tachyarrhythmias (accelerated and/or irregular heart beat), idiopathic subvalvular aortic stenosis, hypertrophic obstructive cardiomyopathy, severe heart disease, particularly acute myocardial infarction, ischaemic heart disease, congestive heart failure, occlusive vascular diseases, particularly arteriosclerosis, arterial hypertension and aneurysm. Caution should also be observed when treating patients with known or suspected prolongation of the QTc interval, either congenital or drug induced (QTc >0.44 seconds). Formoterol itself may induce prolongation of the QTc interval.

Beta-blockers (including eye drops) should be avoided in asthmatic patients. If beta-blockers are administered for compelling reasons, the effect of formoterol will be reduced or abolished. On the other hand, concomitant use of other beta adrenergic drugs can have potentially additive effects, therefore caution is required when theophylline or other beta adrenergic drugs are prescribed concomitantly with formoterol. Concomitant treatment with quinidine, disopyramide, procainamide, phenothiazines, antihistamines, monoamine oxidase inhibitors and tricyclic antidepressants can prolong the QTc-interval and increase the risk of ventricular arrhythmias.

There are no relevant clinical data on the use of the drug in pregnant women. Animal studies using beclometasone dipropionate and formoterol combination showed evidence of toxicity to reproduction after high systemic exposure. There are no relevant clinical data on the use of the drug in lactation in humans. Although no data from animal experiments are available, it is reasonable to assume that beclometasone dipropionate is secreted in milk, like other corticosteroids.

Prior to dispensing to the patient: Store in a refrigerator (2-8°C) (for a maximum of 15 months). After dispensing: Store at temperatures not exceeding 30°C (for a maximum of 2 months).

Vitamin-C Preparations

vitamin C, the water-soluble vitamin, is readily absorbed from the gastrointestinal tract and is widely distributed in the body tissues. It is believed to be involved in biological oxidations and reductions used in cellular respiration. It is essential for the synthesis of collagen and intracellular material. Vitamin C deficiency develops when the dietary intake is inadequate and when increased demand is not fulfilled. Deficiency leads to the development of well defined syndrome known as scurvy, which is characterized by capillary fragility, bleeding (especially from small blood vessels and the gums), anaemia, cartilage and bone lesions and slow healing of wounds.

Oral administration-

• For the prevention of scurvy: 1 tablet daily
• For the treatment of scurvy: 1-2 tablets daily; but dose may be increased depending on the severity of the condition.
• For the reduction of risk of stroke in the elderly: 1-2 tablets daily.
• In other cases: 1 tablet daily or as directed by the physician.
• Maximum safe dose is 2000 mg daily in divided doses.

Parenteral administration-

• Vitamin C is usually administered orally. When oral administration is not feasible or when malabsorption is suspected, the drug may be administered IM, IV, or subcutaneously. When given parenterally, utilization of the vitamin reportedly is best after IM administration and that is the preferred parenteral route.
• For intravenous injection, dilution into a large volume parenteral such as Normal Saline, Water for Injection, or Glucose is recommended to minimize the adverse reactions associated with intravenous injection.
• The average protective dose of vitamin C for adults is 70 to 150 mg daily. In the presence of scurvy, doses of 300 mg to 1 g daily are recommended. However, as much as 6 g has been administered parenterally to normal adults without evidence of toxicity.
• To enhance wound healing, doses of 300 to 500 mg daily for a week or ten days both preoperatively and postoperatively are generally considered adequate, although considerably larger amounts have been recommended. In the treatment of burns, doses are governed by the extent of tissue injury. For severe burns, daily doses of 1 to 2 g are recommended. In other conditions in which the need for vitamin C is increased, three to five times the daily optimum allowances appear to be adequate.
• Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever the solution and container permit.

Vitamin C has little toxicity and only mega-doses of vitamin C may cause diarrhoea, abdominal bloating, iron over-absorption that is harmful in patients with thalassaemia, sideroblastic anemia, and haemochromatosis; hyperoxaluria, hyperuricosuria, and hemolysis in patients with glucose-6 phosphate dehydrogenase deficiency. A pregnant woman taking more than 5 gm/day may suffer fetal abortion.

Ingestion of megadose (more than 1000 mg daily) of vitamin C during pregnancy has resulted in scurvy in neonates. Vitamin C in mega-doses has been contraindicated for patients with hyperoxaluria. Vitamin C itself is a reactive substance in the redox system and can give rise to false positive reactions in certain analytical tests for glucose, uric acid, creatine and occult blood.

Potentially hazardous interactions: Ascorbic acid is incompatible in solution with aminophylline, bleomycin, erythromycin, lactobionate, nafcillin, nitrofurantoin sodium, conjugated oestrogen, sodium bicarbonate, sulphafurazole diethanolamine, chloramphenicol sodium succinate, chlorthiazide sodium and hydrocortisone sodium succinate.

Useful interactions: Ascorbic acid increases the apparent half-life of paracetamol and enhances iron absorption from the gastrointestinal tract.

The drug is safe in normal doses in pregnant women, but a daily intake of 5 gm or more is reported to have caused abortion. The drug may be taken safely during lactation.

Should be stored in a dry place below 30˚C.

Doxophylline is used to treat in following indications:

• Bronchial asthma
• Bronchospasm
• Chronic obstructive pulmonary disease (COPD)
• Pulmonary disease with spastic bronchial component.

Bronchodilator, Methyl xanthine derivatives

Doxophylline is a novel bronchodilator. It structurally differs from Theophylline due to the presence of a dioxolane group in position 7. Doxophylline selectively inhibits phosphodiesterase 4 thereby relaxes bronchial smooth muscle. However, differently from Theophylline, Doxophylline appears to have decreased affinities toward adenosine A1 and A2 receptors, which may account for the better safety profile of the drug. Doxophylline is reported to inhibit platelet activating factor (PAF) and generation of leukotriene production.

Elderly: 200 mg tablet two or three times daily.

Adults: 400 mg tablet two or three times daily or as prescribed by the physician.

Children:

• >12 years of age: 10 ml syrup or 200 mg tablet two or three times daily.
• 6-12 years of age: 6-9 mg/kg body weight two times daily, i.e. if body weight is 10 kg, 3 ml (60 mg) two times daily or as prescribed by the physician.

If required daily dose of Doxophylline is 400 mg then Doxophylline SR tablet to be taken once daily or as prescribed by the physician

Doxophylline rarely causes serious side effects, however possible side effects are similar for taking excess amount of caffeine. These include: nausea, vomiting, headache, upset stomach and heartburn.

Doxophylline is contraindicated in acute myocardial infarction. It is also contraindicated in patients with hypotension, in lactating women & patients who have shown hypersensitivity to its components.

The half-life of xanthine derivatives is influenced by a number of known variables. It may be prolonged in patients with liver disease, in patients with congestive heart failure and in those patients taking certain other drugs like erythromycin, troleandomycin, lincomycin, allopurinol, cimetidine, propanolol and anti-flu vaccine. In these cases, a lower dose of Doxophylline may be needed. Phenytoin, other anticonvulsants and smoking may cause an increase in clearance with a shorter mean half-life. In these cases higher doses of Doxophylline may be needed.

Doxophylline should not be administered together with other xanthine derivatives. Toxic synergism with ephedrine has been documented for xanthines. Like other xanthines, concomitant therapy with troleandomycin, lincomycin, clindamycin, allopurinol, cimetidine, ranitidine, propranolol and anti-flu vaccine may decrease the hepatic clearance of xanthines causing an increase in blood levels. No evidence of a relationship between Doxophylline serum concentrations and toxic events have been reported.

Animal reproduction studies indicate that, Doxophylline does not cause fetal harm when administered to pregnant animals or can not affect reproduction capacity. However, since there is limited experience in human during pregnancy, xanthines should be given to pregnant women only if clearly needed. Doxophylline is contraindicated in nursing mothers.

In case of overdose severe cardiac arrhythmias and tonic-clonic seizure may occur. These effects may represent the first signs of intoxication. The appearance of side effects may require discontinuation of the treatment which, if necessary, at the physician’s discretion, may be resumed at lower doses after all signs and symptoms of toxicity have subsided.

As there is no specific antidote, in case of overdose a symptomatic treatment of cardiovascular collapse should be instituted.

Keep in a dry place away from light and heat. Keep out of the reach of children. Doxophylline should be used only on prescription of specialist physician.
