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.

Brivaracetam is indicated for the treatment of partial-onset seizures in patients 4 years of age and older. As the safety of Brivaracetam injection in pediatric patients has not been established, Brivaracetam injection is indicated for the treatment of partial-onset seizures only in adult patients (16 years of age and older).

Adjunct anti-epileptic drugs

The precise mechanism by which Brivaracetam exerts its anticonvulsant activity is not known. Brivaracetam displays a high and selective affinity for synaptic vesicle protein 2A (SV2A) in the brain, which may contribute to the anticonvulsant effect.

Brivaracetam binds SV2A with high affinity. SV2A is known to play a role in epileptogenesis through modulation of synaptic GABA release. It is thought that brivaracetam exerts its anti-epileptogenic effects through its binding to SV2A. Brivaracetam is also known to inhibit Na⁺ channels which may also contribute to its anti-epileptogenic action

Adults (16 Years and older): The recommended starting dosage for monotherapy or adjunctive therapy is 50 mg twice daily (100 mg per day).

Based on individual patient tolerability and therapeutic response, the dosage may be adjusted down to 25 mg twice daily (50 mg per day) or up to 100 mg twice daily (200 mg per day).

Pediatric Patients (4 Years to less than 16 Years): The recommended dosage is based on body weight and is administered orally twice daily

Injection: for intravenous and adult use only when oral administration is temporarily not feasible; dosing is the same as oral regimen.

Brivaracetam injection should be administered intravenously over 2 to 15 minutes. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Product with particulate matter or discoloration should not be used. Brivaracetam injection is for single dose only.

Most common adverse reactions (at least 5% for Brivaracetam and at least 2% more frequently than placebo) are somnolence/sedation, dizziness, fatigue, and nausea or vomiting.

Hypersensitivity to brivaracetam or any of the inactive ingredients in Brivaracetam

Suicidal Behavior and Ideation: Monitor patients for suicidal behavior and ideation.

Neurological Adverse Reactions: Monitor for somnolence and fatigue, and advise patients not to drive or operate machinery until they have gained sufficient experience on Brivaracetam.

Psychiatric Adverse Reactions: Behavioral reactions including psychotic symptoms, irritability, depression, aggressive behavior, and anxiety; monitor patients for symptoms.

Hypersensitivity: Bronchospasm and Angioedema: Advise patients to seek immediate medical care. Discontinue and do not restart Brivaracetam if hypersensitivity occurs. 

Withdrawal of Antiepileptic Drugs: Brivaracetam should be gradually withdrawn.

Rifampin: Because of decreased concentrations, increasing Brivaracetam dosage in patients on concomitant rifampin is recommended.

Carbamazepine: Because of increased exposure to carbamazepine metabolite, if tolerability issues arise, consider reducing carbamazepine dosage in patients on concomitant Brivaracetam.

Phenytoin: Because phenytoin concentrations can increase, phenytoin levels should be monitored in patients on concomitant Brivaracetam.

Levetiracetam: Brivaracetam had no added therapeutic benefit when co-administered with levetiracetam.

There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antiepileptic drugs (AEDs), such as Brivaracetam, during pregnancy. No data are available regarding the presence of brivaracetam in human milk, the effects on the breastfed infant, or the effects of the drug on milk production. Studies in lactating rats have shown excretion of brivaracetam or metabolites in milk

Hepatic Impairment: Dose adjustment is recommended for all stages of hepatic impairment.

Renal Impairment: Dose adjustments are not required for patients with impaired renal function.

Drugs for miotics and glaucoma

Brimonidine is an α-2 adrenoreceptor agonist that is more selective for the α-2 adrenoreceptor than α-1. Topical administration of Brimonidine Tartrate eye drops decreases intraocular pressure (IOP) in humans. When used as directed Brimonidine Tartrate have the action of reducing elevated IOP with minimal effect on cardiovascular parametres. Brimonidine Tartrate eye drops have a rapid onset of action with the peak ocular hypotensive effect occurring at two hours post-dosing. The duration of effect is 12 hours or greater. Fluorophotometric studies in animals and humans suggest that Brimonidine Tartrate has a dual mechanism of action. Brimonidine Tartrate eye drops lower IOP by reducing aqueous humor production and enhancing uveoscleral outflow.

0.2% ophthalmic solution: The recommended dose is one drop of 0.2% ophthalmic solution in the affected eye(s) three times daily, approximately 8 hours apart. This ophthalmic solution may be used concomitantly with other topical ophthalmic drug products to lower intraocular pressure. If more than one topical ophthalmic product is being used, the products should be administered at least 5 minutes apart.

0.15% ophthalmic solution: The recommended dose is one drop of 0.15% ophthalmic solution in the affected eye(s) three times daily, approximately 8 hours apart.

0.025% ophthalmic solution: Instill 1 drop in the affected eye(s) every 6-8 hours. Do not use it more than 4 times daily. If more than one topical ophthalmic product is being used, the products should be administered at least 5 minutes apart.

Adverse events occurring in approximately 10-30% of the subjects, in descending order of incidence, included oral dryness, ocular hyperemia, burning and stinging, headache, blurring, foreign body sensation, fatigue/drowsiness, conjunctival follicles, ocular allergic reactions, and ocular pruritus. Events occurring in approximately 3-9% of the subjects, in descending order included corneal staining/erosion, photophobia, eyelid erythema, ocular ache/pain, ocular dryness, tearing, upper respiratory symptoms, eyelid edema, conjunctival edema, dizziness, blepharitis, ocular irritation, gastrointestinal symptoms, asthenia, conjunctival blanching, abnormal vision and muscular pain. The following adverse reactions were reported in less than 3% of the patients: lid crusting, conjunctival hemorrhage, abnormal taste, insomnia, conjunctival discharge, depression, hypertension, anxiety, palpitations/arrhythmias, nasal dryness and syncope.

Brimonidine Tartrate ophthalmic solution is contraindicated in patients with hypersensitivity to Brimonidine Tartrate. It is also contraindicated in patients receiving monoamine oxidase (MAO) inhibitor therapy.

Although Brimonidine Tartrate ophthalmic solution had minimal effect on the blood pressure of patients in clinical studies, caution should be exercised in treating patients with severe cardiovascular disease. Brimonidine Tartrate ophthalmic solution should be used with caution in patients with depression, cerebral or coronary insufficiency, Raynaud's phenomenon, orthostatic hypotension or thromboangiitis obliterans.

Although specific drug interaction studies have not been conducted with Brimonidine Tartrate ophthalmic solution, the possibility of an additive or potentiating effect with CNS depressants (alcohol, barbiturates, opiates, sedatives, or anesthetics) should be considered. Alpha-agonists, as a class, may reduce pulse and blood pressure. Caution in using concomitant drugs such as beta-blockers (ophthalmic and systemic), antihypertensives and/or cardiac glycosides is advised. Tricyclic antidepressants have been reported to blunt the hypotensive effect of systemic clonidine. It is not known whether the concurrent use of these agents with Brimonidine Tartrate ophthalmic solution in humans can lead to resulting interference with the IOP lowering effect. No data on the level of circulating catecholamines after administration of Brimonidine Tartrate ophthalmic solution are available. Caution, however, is advised in patients taking Tricyclic antidepressants which can affect the metabolism and uptake of circulating amines.

There are no adequate and well-controlled studies in pregnant women. In animal studies, Brimonidine crossed the placenta and entered into the fetal circulation to a limited extent. Brimonidine Tartrate ophthalmic solution 0.2% should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus. It is not known whether this drug is excreted in human milk; in animal studies Brimonidine Tartrate was excreted in breast milk. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Store below 30°C in a cool and dry place protected from light. Keep out of reach of children. Do not touch the dropper tip to surfaces since this may contaminate the solution. Do not use after 30 days of first opening.

Caution, however, is advised in patients taking Tricyclic antidepressants which can affect the metabolism and uptake of circulating amines.

There are no adequate and well-controlled studies in pregnant women. In animal studies, Brimonidine crossed the placenta and entered into the fetal circulation to a limited extent. Brimonidine Tartrate ophthalmic solution 0.2% should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus. It is not known whether this drug is excreted in human milk; in animal studies Brimonidine Tartrate was excreted in breast milk. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Store below 30°C in a cool and dry place protected from light. Keep out of reach of children. Do not touch the dropper tip to surfaces since this may contaminate the solution. Do not use after 30 days of first opening.

Brigatinib is indicated for the treatment of patients with anaplastic lymphoma kinase (ALK)-positive metastatic Non-small cell lung cancer (NSCLC) who have progressed on or are intolerant to Crizotinib.

Cytotoxic Chemotherapy

Brigatinib is a tyrosine kinase inhibitor with in vitro activity at clinically achievable concentrations against multiple kinases including ALK, ROS1, insulin-like growth factor-1 receptor (IGF-1R), and FLT-3 as well as EGFR deletion and point mutations. Brigatinib inhibited autophosphorylation of ALK and ALK-mediated phosphorylation of the downstream signaling proteins STAT3, AKT, ERK1/2, and S6 in in-vitro and in vivo assays. Brigatinib also inhibited the in vitro proliferation of cell lines expressing EML4-ALK and NPM ALK fusion proteins and demonstrated dose-dependent inhibition of EML4-ALK-positive NSCLC xenograft growth in mice. Brigatinib exposure-response relationships and the time course of the pharmacodynamic response are unknown.

Absorption: Following administration of single oral doses of Brigatinib of 30 to 240 mg, the median time to peak concentration (Tmax) ranged from 1 to 4 hours.

Distribution: Brigatinib is 66% bound to human plasma proteins and the binding is not concentration-dependent in vitro. The blood to plasma concentration ratio is 0.69. Following oral administration of Brigatinib 180 mg once daily, the mean apparent volume of distribution (Vz/F) of Brigatinib at steady-state was 153 L.

Elimination: Following oral administration of Brigatinib 180 mg once daily, the mean apparent oral clearance (CL/F) of Brigatinib at steady-state is 12.7 L/h and the mean plasma elimination half-life is 25 hours.

Metabolism: Brigatinib is primarily metabolized by CYP2C8 and CYP3A4 in vitro. Following oral administration of a single 180 mg dose of radiolabeled Brigatinib to healthy subjects, N-demethylation and cysteine conjugation were the two major metabolic pathways. Unchanged Brigatinib (92%) and its primary metabolite, AP26123 (3.5%), were the major circulating radioactive components. The steady-state AUC of AP26123 was less than 10% of AUC of Brigatinib exposure in patients. The metabolite, AP26123, inhibited ALK with approximately 3-fold lower potency than Brigatinib in vitro.

Excretion: Following oral administration of a single 180 mg dose of radiolabeled Brigatinib to healthy subjects, 65% of the administered dose was recovered in feces and 25% of the administered dose was recovered in urine. Unchanged Brigatinib represented 41% and 86% of the total radioactivity in feces and urine, respectively.

The recommended dosing regimen for Brigatinib is:

• 90 mg orally once daily for the first 7 days;
• If 90 mg is tolerated during the first 7 days, the dose should be increased to 180 mg orally once daily.

Brigatinib should be administered until disease progression or unacceptable toxicity. If Brigatinib is interrupted for 14 days or longer for reasons other than adverse reactions, treatment should be resumed at 90 mg once daily for 7 days before increasing to the previously tolerated dose. Brigatinib may be taken with or without food. Patients should be instructed to swallow tablets whole. Tablets should not be crushed or chewed. If a dose of Brigatinib is missed or vomiting occurs after taking a dose, an additional dose should not be administered and take the next dose of Brigatinib should be taken at the scheduled time.

Pediatric Use: The safety and efficacy of Brigatinib in pediatric patients have not been established.

It is contraindicated in patients with known hypersensitivity to Brigatinib or any other components of this product.

Interstitial Lung Disease (ILD)/Pneumonitis: Severe, life-threatening, and fatal pulmonary adverse reactions consistent with interstitial lung disease (ILD)/pneumonitis have occurred with Brigatinib. It should be withheld in any patient with new or worsening respiratory symptoms, and promptly evaluate for ILD/pneumonitis or other causes of respiratory symptoms (e.g., pulmonary embolism, tumor progression, and infectious pneumonia). Brigatinib should be discontinued permanently for Grade 3 or 4 ILD/pneumonitis or recurrence of Grade 1 or 2 ILD/pneumonitis.

Hypertension: Hypertension was reported in 11% of patients in the 90 mg group who received Brigatinib and 21% of patients in the 90-180 mg group. Grade 3 hypertension occurred in 5.9% of patients overall. Blood pressure should be controlled prior to treatment with Brigatinib. Blood pressure should be monitored after 2 weeks and at least monthly thereafter during treatment with Brigatinib. It should be withheld for Grade 3 hypertension despite optimal antihypertensive therapy. Permanent discontinuation of treatment should be considered with Brigatinib for Grade 4 hypertension or recurrence of Grade 3 hypertension. Caution should be used when administering Brigatinib in combination with antihypertensive agents that cause bradycardia.

Bradycardia: Bradycardia can occur with Brigatinib. Heart rate and blood pressure should be monitored during treatment with Brigatinib. Patients should be monitored more frequently if concomitant use of drug known to cause bradycardia cannot be avoided.

Visual Disturbance: Adverse reactions leading to visual disturbance including blurred vision, diplopia, and reduced visual acuity, were reported in 7.3% of patients receiving Brigatinib in the 90 mg group and 10% of patients in the 90-180 mg group. Patients should be advised to report any visual symptoms. Brigatinib should be withheld and obtained an ophthalmologic evaluation in patients with new or worsening visual symptoms of Grade 2 or greater severity. Upon recovery of Grade 2 or Grade 3 visual disturbances to Grade 1 severity or baseline, Brigatinib should be resumed at a reduced dose. Treatment with Brigatinib should be permanently discontinued for Grade 4 visual disturbances.

Creatine Phosphokinase (CPK) Elevation: Creatine phosphokinase (CPK) elevation occurred in 27% of patients receiving Brigatinib in the 90 mg group and 48% of patients in the 90 mg-180 mg group. Patients should be advised to report any unexplained muscle pain, tenderness, or weakness. CPK levels should be monitored during Brigatinib treatment. Brigatinib should be withheld for Grade 3 or 4 CPK elevation.

Pancreatic Enzyme Elevation: Amylase elevation occurred in 27% of patients in the 90 mg group and 39% of patients in the 90→180 mg group. Lipase elevations occurred in 21% of patients in the 90 mg group and 45% of patients in the 90→180 mg group. Lipase and amylase should be monitored during treatment with Brigatinib. Brigatinib should be withheld for Grade 3 or 4 pancreatic enzyme elevation. 

Hyperglycemia: 43% of patients who received Brigatinib experienced new or worsening hyperglycemia. Grade 3 hyperglycemia, based on laboratory assessment of serum fasting glucose levels, occurred in 3.7% of patients. Two of 20 (10%) patients with diabetes Brigatinib or glucose intolerance at baseline required initiation of insulin while receiving Brigatinib. Fasting serum glucose should be assessed prior to initiation of Brigatinib and monitored periodically thereafter. Antihyperglycemic medications should be initiated or optimized as needed. If adequate hyperglycemic control cannot be achieved with optimal medical management, Brigatinib should be withheld until adequate hyperglycemic control is achieved and considered reducing the dose of Brigatinib.

Drugs that may Increase Brigatinib Plasma Concentrations: Strong CYP3A Inhibitors: Coadministration of Itraconazole, a strong CYP3A inhibitor, increased Brigatinib plasma concentrations and may result in increased adverse reactions. Concomitant use of strong CYP3A inhibitors with Brigatinib, including but not limited to certain Antivirals (e.g., Boceprevir, Cobicistat, Indinavir, Lopinavir, Nelfinavir, Ritonavir, Saquinavir), Macrolide antibiotics (e.g., Clarithromycin), Antifungals (e.g., Itraconazole, Ketoconazole, Posaconazole, Voriconazole), and Conivaptan should be avoided. Grapefruit or grapefruit juice should be avoided as it may also increase plasma concentrations of Brigatinib. If concomitant use of a strong CYP3A inhibitor cannot be avoided, the dose of Brigatinib should be reduced by approximately 50%.

Drugs that may Decrease Brigatinib Plasma Concentrations: Strong CYP3A Inducers: Coadministration of Brigatinib with Rifampin, a strong CYP3A inducer, decreased Brigatinib plasma concentrations and may result in decreased efficacy. Concomitant use of strong CYP3A inducers with Brigatinib should be avoided, including but not limited to Rifampin, Carbamazepine, Phenytoin, and St. John's Wort.

Drugs that may have their Plasma Concentrations altered by Brigatinib: CYP3A Substrates: Brigatinib induces CYP3A in vitro and may decrease concentrations of CYP3A substrates. Coadministration of ALUNBRIG with CYP3A substrates, including hormonal contraceptives, can result in decreased concentrations and loss of efficacy of CYP3A substrates.

Pregnancy: There are no clinical data on the use of Brigatinib in pregnant women. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, advise the patient of the potential risk to a fetus.

Lactation: There are no data regarding the secretion of Brigatinib in human milk or its effects on the breastfed infant or milk production. Because of the potential for adverse reactions in breastfed infants, lactating women should be advised not to breastfeed during treatment with Brigatinib and for 1 week following the final dose.

Females Reproductive Potential: Females of reproductive potential should be advised to use effective non-hormonal contraception during treatment with Brigatinib and for at least 4 months after the final dose. Patients should be counseled to use a non-hormonal method of contraception since Brigatinib can render some hormonal contraceptives ineffective.

Males Reproductive Potential: Because of the potential for genotoxicity, males with female partners of reproductive potential should be advised to use effective contraception during treatment with Brigatinib and for at least 3 months after the final dose.

Infertility: Based on findings in male reproductive organs in animals, Brigatinib may cause reduced fertility in males.

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

Drugs for miotics and glaucoma

Brimonidine is an α-2 adrenoreceptor agonist that is more selective for the α-2 adrenoreceptor than α-1. Topical administration of Brimonidine Tartrate eye drops decreases intraocular pressure (IOP) in humans. When used as directed Brimonidine Tartrate have the action of reducing elevated IOP with minimal effect on cardiovascular parametres. Brimonidine Tartrate eye drops have a rapid onset of action with the peak ocular hypotensive effect occurring at two hours post-dosing. The duration of effect is 12 hours or greater. Fluorophotometric studies in animals and humans suggest that Brimonidine Tartrate has a dual mechanism of action. Brimonidine Tartrate eye drops lower IOP by reducing aqueous humor production and enhancing uveoscleral outflow.

0.2% ophthalmic solution: The recommended dose is one drop of 0.2% ophthalmic solution in the affected eye(s) three times daily, approximately 8 hours apart. This ophthalmic solution may be used concomitantly with other topical ophthalmic drug products to lower intraocular pressure. If more than one topical ophthalmic product is being used, the products should be administered at least 5 minutes apart.

0.15% ophthalmic solution: The recommended dose is one drop of 0.15% ophthalmic solution in the affected eye(s) three times daily, approximately 8 hours apart.

0.025% ophthalmic solution: Instill 1 drop in the affected eye(s) every 6-8 hours. Do not use it more than 4 times daily. If more than one topical ophthalmic product is being used, the products should be administered at least 5 minutes apart.

Adverse events occurring in approximately 10-30% of the subjects, in descending order of incidence, included oral dryness, ocular hyperemia, burning and stinging, headache, blurring, foreign body sensation, fatigue/drowsiness, conjunctival follicles, ocular allergic reactions, and ocular pruritus. Events occurring in approximately 3-9% of the subjects, in descending order included corneal staining/erosion, photophobia, eyelid erythema, ocular ache/pain, ocular dryness, tearing, upper respiratory symptoms, eyelid edema, conjunctival edema, dizziness, blepharitis, ocular irritation, gastrointestinal symptoms, asthenia, conjunctival blanching, abnormal vision and muscular pain. The following adverse reactions were reported in less than 3% of the patients: lid crusting, conjunctival hemorrhage, abnormal taste, insomnia, conjunctival discharge, depression, hypertension, anxiety, palpitations/arrhythmias, nasal dryness and syncope.

Brimonidine Tartrate ophthalmic solution is contraindicated in patients with hypersensitivity to Brimonidine Tartrate. It is also contraindicated in patients receiving monoamine oxidase (MAO) inhibitor therapy.

Although Brimonidine Tartrate ophthalmic solution had minimal effect on the blood pressure of patients in clinical studies, caution should be exercised in treating patients with severe cardiovascular disease. Brimonidine Tartrate ophthalmic solution should be used with caution in patients with depression, cerebral or coronary insufficiency, Raynaud's phenomenon, orthostatic hypotension or thromboangiitis obliterans.

Although specific drug interaction studies have not been conducted with Brimonidine Tartrate ophthalmic solution, the possibility of an additive or potentiating effect with CNS depressants (alcohol, barbiturates, opiates, sedatives, or anesthetics) should be considered. Alpha-agonists, as a class, may reduce pulse and blood pressure. Caution in using concomitant drugs such as beta-blockers (ophthalmic and systemic), antihypertensives and/or cardiac glycosides is advised. Tricyclic antidepressants have been reported to blunt the hypotensive effect of systemic clonidine. It is not known whether the concurrent use of these agents with Brimonidine Tartrate ophthalmic solution in humans can lead to resulting interference with the IOP lowering effect. No data on the level of circulating catecholamines after administration of Brimonidine Tartrate ophthalmic solution are available. Caution, however, is advised in patients taking Tricyclic antidepressants which can affect the metabolism and uptake of circulating amines.

There are no adequate and well-controlled studies in pregnant women. In animal studies, Brimonidine crossed the placenta and entered into the fetal circulation to a limited extent. Brimonidine Tartrate ophthalmic solution 0.2% should be used during pregnancy only if the potential benefit to the mother justifies the potential risk to the fetus.

This eye drop is indicated for the reduction of elevated intraocular pressure (IOP) in patients with glaucoma or ocular hypertension.

Drugs for miotics and glaucoma

This eye drops is comprised of two components: Brimonidine Tartrate & Timolol Maleate. Brimonidine Tartrate is a selective alpha-2 adrenergic receptor agonist having a dual mechanism of action. It decreases aqueous humor production and increases nonpressure dependent uveoscleral outflow. Timolol Maleate is a β-adrenergic receptor antagonist that does not have significant intrinsic sympathomimetic, direct myocardial depressant, or local anesthetic (membrane-stabilizing) activity. It lowers IOP by reducing aqueous humor production. Therefore the combination of both drugs gives a rapid onset of action, with peak ocular hypotensive effect seen within two hours of administration.

Instill 1 drop in the affected eye(s) twice daily.

The most common side effects are allergic conjunctivitis, conjunctival folliculosis, conjunctival hyperaemia, eye pruritus and ocular burning or stinging.

Contraindicated in patients with hypersensitivity to any component of this product. Also contraindicated in bronchial asthma, severe chronic obstructive pulmonary disease, sinus bradycardia, second or third-degree atrioventricular block, overt cardiac failure and cardiogenic shock.

Like other topically applied ophthalmic agents, it may be absorbed systemically. Due to the presence of Timolol, the same types of cardiovascular and pulmonary adverse reactions as seen with systemic beta-blockers may occur. Cautions should be exercised in treating patients with severe or unstable and uncontrolled cardiovascular or pulmonary diseases.

Specific drug interaction studies have not been conducted.

There are no adequate and well-controlled studies in pregnant women. Combipres should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Timolol has been detected in human milk but it is not known whether Brimonidine Tartrate is excreted in human milk. A decision should be made whether to discontinue nursing or to discontinue taking into account the importance of the drug to the mother.

Use in children: Safety and effectiveness in children below the age of 2 years have not been established.

Use in elderly patients: No overall differences in safety or effectiveness have been observed between elderly and other adult patients.

Store at a cool & dry place, protect from light. Do not use longer than 30 days after the first opening of the bottle. Keep out of the reach of children.

Cautions should be exercised in treating patients with severe or unstable and uncontrolled cardiovascular or pulmonary diseases.

Specific drug interaction studies have not been conducted.

There are no adequate and well-controlled studies in pregnant women. Combipres should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. Timolol has been detected in human milk but it is not known whether Brimonidine Tartrate is excreted in human milk. A decision should be made whether to discontinue nursing or to discontinue taking into account the importance of the drug to the mother.

Use in children: Safety and effectiveness in children below the age of 2 years have not been established.

Use in elderly patients: No overall differences in safety or effectiveness have been observed between elderly and other adult patients.

Store at a cool & dry place, protect from light. Do not use longer than 30 days after the first opening of the bottle. Keep out of the reach of children.

Drugs for miotics and glaucoma

This eye drops is comprised of two components: Brimonidine Tartrate & Timolol Maleate. Brimonidine Tartrate is a selective alpha-2 adrenergic receptor agonist having a dual mechanism of action. It decreases aqueous humor production and increases nonpressure dependent uveoscleral outflow. Timolol Maleate is a β-adrenergic receptor antagonist that does not have significant intrinsic sympathomimetic, direct myocardial depressant, or local anesthetic (membrane-stabilizing) activity. It lowers IOP by reducing aqueous humor production. Therefore the combination of both drugs gives a rapid onset of action, with peak ocular hypotensive effect seen within two hours of administration.

Instill 1 drop in the affected eye(s) twice daily.

The most common side effects are allergic conjunctivitis, conjunctival folliculosis, conjunctival hyperaemia, eye pruritus and ocular burning or stinging.

Brinzolamide is a carbonic anhydrase inhibitor which reduce intraocular pressure (IOP) by decreasing aqueous humor secretion in the ciliary processes of the eye.

Brimonidine Tartrate is an alpha 2 adrenergic receptor agonist which reduces IOP by decreasing aqueous humor production and increasing uveoscleral outflow.

Instill one drop in the affected eye(s) three times daily. If more than one topical ophthalmic drug is being used, the drugs should be administered at least five minutes apart. Shake well before use.

The most commonly reported side effects include blurred vision, eye irritation, bad taste and dry mouth.

It is contraindicated in patients who are hypersensitivity to Brinzolamide, Brimonidine Tartrate, or to any ingredient in the formulation and Neonates and Infants (under the age of 2 years).

Shake well before use. For ophthalmic use only. Contact lenses should be removed during instillation of Brinzolamide and Brimonidine Tartrate ophthalmic suspension, but may be reinserted 15 minutes after instillation.

In patients treated with this drop rare instances to drug interactions have occurred with high-dose salicylate therapy, CNS Depressants, Antihypertensives/ Cardiac Glycosides, Tricyclic Antidepressants, Monoamine Oxidase Inhibitors. Therefore, the potential for such drug interactions should be considered in patients receiving Brinzolamide + Brimonidine Tartrate .

Pregnancy category C. There are no adequate and well-controlled studies in pregnant women. Brinzolamide and Brimonidine Tartrate ophthalmic suspension should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

It is not known whether Brinzolamide or Brimonidine Tartrate are excreted in human milk. Caution should be exercised while giving this ophthalmic suspension to a nursing mother.

Use in children: Safety & effectiveness in children below the age of 2 years have not been established.

Use in elderly patients: No overall differences in safety and effectiveness have been observed between elderly and other adult patients.

Although no human data are available, electrolyte imbalance, development of an acidotic state, and possible nervous system effects may occur following an oral overdose of Brinzolamide. Serum electrolyte levels (particularly potassium) and blood pH levels should be monitored. Very limited information exists on accidental ingestion of Brimonidine Tartrate in adults; the only adverse event reported to date has been hypotension. Symptoms of Brimonidine Tartrate overdose have been reported in neonates, infants, and children receiving Brimonidine Tartrate as part of medical treatment of congenital glaucoma or by accidental oral ingestion. Treatment of an oral overdose includes supportive and symptomatic therapy; a patent airway should be maintained.

Store at room temperature & protect from light. Do not touch dropper tip to any surface. It is desirable that the contents should not be used more than one month after first opening of the bottle. Shake well before use & do not freeze.

Brinzolamide Ophthalmic Suspension is indicated as monotherapy, or as adjunctive therapy to beta-blockers in the treatment of elevated intraocular pressure in ocular hypertension, or open-angle glaucoma.

Drugs for miotics and glaucoma

Carbonic anhydrase (CA) is an enzyme found in many tissues of the body including the eye. It catalyses the reversible reaction involving the hydration of carbon dioxide and the dehydration of carbonic acid. It exists as a number of isoenzymes, the most active being carbonic anhydrase II (CA-II), found primarily in red blood cells, but also in other tissues. Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion, presumably by slowing the formation of bicarbonate ions with subsequent reduction in sodium and fuid transport.

Following topical ocular administration, brinzolamide inhibits aqueous humor formation and reduces elevated intraocular pressure. Elevated intraocular pressure is a major risk factor in the pathogenesis of optic nerve damage and glaucomatous visual feld loss.

The recommended dose is one drops of this eye drop in the conjunctival sac of the affected eye(s) twice daily. Some patients may have a better response with one drop three times a day. Shake well before use.

Reported side effects are blurred vision and bitter, sour or unusual taste. Other side effects are blepharitis, dermatitis, dry eye, foreign body sensation, headache, hyperemia, ocular discharge, ocular discomfort, ocular keratitis, ocular pain, ocular pruritus and rhinitis.

It is contraindicated in patients who are hypersensitive to any component of this product.

In patients treated with oral carbonic anhydrase inhibitors, rare instances to drug interactions have occurred with high-dose salicylate therapy. Therefore, the potential for such drug interactions should be considered in patients receiving Brinzolamide.

Pregnancy category C. There are no adequate and well-controlled studies in pregnant women. Brinzolamide 1% ophthalmic suspension should be used during pregnancy only if the benefit justifies the potential risk to the fetus.

Use in lactation: It is not known whether Brinzolamide 1% ophthalmic suspension is excreted in human milk. So, lactating mother should discontinue nursing or to discontinue the drug, depending upon the importance of the drug to the mother.

Although no human data are available, electrolyte imbalance, development of an acidosis state, and possible nervous system effects may occur following oral administration of an overdose. Serum electrolyte levels (particularly potassium) and blood pH levels should be monitored.

Store at room temperature & protect from light. Do not touch dropper tip to any surface. It is desirable that the contents should not be used more than four weeks after first opening of the bottle. Protect from freezing.

Brinzolamide is a highly specific inhibitor of CA-II, which is the main CA isoenzyme involved in the secretion of aqueous humor. Inhibition of CA in the ciliary process of the eye slows the formation of bicarbonate, and reduces sodium and fluid transport. This results in a reduction in the rate of aqueous humor secretion and the intraocular pressure. Brinzolamide is absorbed systemically following topical ocular administration. Since it has a high affinity for CA-II, brinzolamide binds extensively to red blood cells, where CA-II is primarily found. As sufficient CA-II activity remains, adverse effects resulting from the systemic inhibition of CA by brinzolamide are not observed. The metabolite N-desethyl brinzolamide is also formed. This metabolite binds to CA and accumulates in red blood cells as well. In the presence of brinzolamide, the metabolite binds mainly to carbonic anhydrase I (CA-I).

Like propranolol and nadolol, timolol competes with adrenergic neurotransmitters such as catecholamines for binding at beta(1)-adrenergic receptors in the heart and vascular smooth muscle and beta(2)-receptors in the bronchial and vascular smooth muscle. Beta(1)-receptor blockade results in a decrease in resting and exercise heart rate and cardiac output, a decrease in both systolic and diastolic blood pressure, and, possibly, a reduction in reflex orthostatic hypotension. Beta(2)-blockade results in an increase in peripheral vascular resistance. The exact mechanism whereby timolol reduces ocular pressure is still not known. The most likely action is by decreasing the secretion of aqueous humor.
