Description
Generics:
Dorzolamide + Timolol
Dosage Form: Opthalmic solution.
Indications:
This Eye Drops is indicated for the treatment of elevated intraocular pressure in patients with open angle glaucoma or ocular hypertension who are insufficiently responsive to topical beta blockers.
Pharmacology:
Dorzolamide, a carbonic anhydrase inhibitor, has actions similar to acetazolamide. By inhibiting carbonic anhydrase in the ciliary processes of the eye, dorzolamide decreases aqueous humor secretion. Used together, there is additional intraocular pressure reduction compared to using either component alone, but the reduction is not as much as concomitant admin of dorzolamide tid and timolol bid.
Timolol maleate, a nonselective β-adrenergic blocker, reduces aqueous humor formation.
Dosage guideline:
Twice daily.
Instill one drop in the conjunctival sac of the affected eye(s) twice daily.
Route of administration: Intra ocular.
Interaction:
Oral calcium channel blockers, catecholamine-depleting medicines or -blockers, antiarrhythmics (e.g. amiodarone), digitalis glycosides, parasympathomimetics, opioids, and MAOIs cause additive hypotension and bradycardia.
