Concise Prescribing Info
Contents
Timolol maleate
Indications/Uses
Reduction of elevated IOP in conditions eg, ocular HTN, chronic open-angle glaucoma (including aphakic patients), some cases of secondary glaucoma.
Dosage/Direction for Use
Adult & childn >12 yr Instill 1 drop bid in the affected eye/s.
Contraindications
Hypersensitivity to timolol maleate or other β-blocking agents. Cardiogenic shock; overt cardiac failure; 2nd & 3rd degree AV block; sinus bradycardia; presence or history of bronchial asthma or of severe COPD; severe peripheral circulatory disturbances (Raynaud disease).
Special Precautions
History of atopy or severe anaphylactic reaction to a variety of allergens. May be systemically absorbed & adverse reactions seen w/ oral β-blockers may occur. Reports of resp & cardiac reactions including death due to bronchospasm in patients w/ asthma, & rarely, death associated w/ cardiac failure; choroidal detachment w/ aq suppressant therapy (eg, acetazolamide) after filtration procedures; bacterial keratitis. β-adrenergic blockade has been reported to potentiate muscle weakness consistent w/ certain myasthenic symptoms eg, diplopia, ptosis, & generalized weakness. Development of intercurrent ocular condition eg, trauma, ocular surgery or infection. Patients w/ sick sinus syndrome, Prinzmetal's angina, untreated phaechromocytoma, metabolic acidosis, HTN, & diabetes. Adequately control cardiac failure prior to therapy. Watch for signs of cardiac failure in patients w/ history of severe cardiac disease. Remove soft contact lenses prior to instillation & do not re-insert earlier than 15 min after use. Avoid allowing of container tip to contact the eye-surrounding structures. Prolonged therapy. Not to be concurrently used w/ another topical ophth β-adrenergic blocking agents. Use w/ miotic & not alone when used to reduce IOP in angle-closure glaucoma. At least 10-min interval between each application is recommended when additional ophth medication is used. Dizziness, fatigue, transient ocular irritation, blurred vision & lacrimation may occasionally occur & may affect ability to drive & use machines. Not to be used during pregnancy. Not recommended during lactation. Not recommended in childn <12 yr.
Adverse Reactions
Urination difficulties; mesenteric arterial thrombosis, ischaemic colitis; agranulocytosis, thrombocytopenic purpura; reversible mental depression progressing to catatonia, short-term memory loss, emotional lability, slightly clouded sensorium & decreased performance on neuropsychometrics; erythematous rash, fever combined w/ aching & sore throat, laryngospasm w/ resp distress; Peyronie's disease.
Drug Interactions
Occasional reports of mydriasis w/ adrenaline. Effects of IOP or known effects of systemic β-blockade (eg, hypotension or bradycardia) may be exaggerated w/ oral β-blocking agent. -ve effect on contractility & AV conduction w/ Ca channel blockers eg, verapamil & diltiazem. May increase AV conduction time w/ digitalis glycosides in association w/ Ca channel blockers. Potentiation of hypotension &/or marked bradycardia w/ catecholamine-depleting drugs eg, rauwolfia alkaloids, reserpine. Increased risk of rebound HTN w/ clonidine discontinuation. Potentiation of bradycardia, sinus arrest & AV block w/ class I antiarrhythmic drugs eg, disopyramide, quinidine & amiodarone. Increased risk of myocardial depression & hypotension w/ anaesth drugs. Plasma level may be increased w/ cimetidine, hydralazine, phenothiazines & alcohol.
