Mode of Action

Timolol maleate, a nonselective beta-adrenergic blocker, reduces aqueous humor formation. 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.

Interaction

Additive hypotension and bradycardia with oral calcium channel blockers, catecholamine-depleting drugs or beta-blockers, antiarrhythmics (e.g. amiodarone), digitalis glycosides, parasympathomimetics, narcotics and MAOIs. Additive systemic side effects with oral carbonic anhydrase or beta-blockers; avoid concurrent use. Additive systemic beta-blockade with CYP2D6 inhibitors (e.g. quinidine, SSRIs) and timolol.
