🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
This medicine lowers intraocular pressure by reducing the production of aqueous humour through two complementary mechanisms. Dorzolamide inhibits carbonic anhydrase II in the ciliary body, which decreases bicarbonate and fluid secretion. Timolol blocks beta-adrenergic receptors on the ciliary epithelium, which reduces cyclic AMP and further decreases aqueous humour formation. The combined effect is greater than either agent alone.
