Tương tác
Concurrent use with oral carbonic anhydrase inhibitors (e.g. acetazolamide, methazolamide) may lead to additive systemic effects. CYP3A4 inhibitors (e.g. ketoconazole, itraconazole, clotrimazole, ritonavir, troleandomycin) may inhibit the metabolism of brinzolamide. Concurrent use with high-dose salicylates may lead to toxicity.
Tác dụng
Description: Mechanism of Action: Brinzolamide is an inhibitor of carbonic anhydrase II (CAII), the main isoenzyme involved in aqueous humour secretion. It inhibits carbonic anhydrase in the ciliary processes of the eye, presumably by slowing bicarbonate formation and reducing Na and fluid transport, thus reducing aqueous humour secretion and subsequently decreasing intraocular pressure (IOP). Pharmacokinetics: Absorption: Absorbed into systemic circulation. Distribution: Accumulates in RBCs. Plasma protein binding: Approx 60%. Metabolism: Metabolised to N-desethyl brinzolamide, which also binds to carbonic anhydrase and accumulates in RBCs. Excretion: Mainly via urine (as unchanged drug and metabolites).
