安普乐定 (Iopidine)

概览

Apraclonidine is an alpha adrenergic agonist used to treat raised intraocular pressure.

作用机制

Apraclonidine is a relatively selective alpha2 adrenergic receptor agonist that stimulates alpha1 receptors to a lesser extent. It has a peak ocular hypotensive effect occurring at two hours post-dosing. The exact mechanism of action is unknown, but fluorophotometric studies in animals and humans suggest that Apraclonidine has a dual mechanism of action by reducing aqueous humor production through the constriction of afferent ciliary process vessels, and increasing uveoscleral outflow.

适应症

For prevention or reduction of intraoperative and postoperative increases in intraocular pressure (IOP) before and after ocular laser surgery when used prophylactically. Also used as a short-term adjunctive therapy in patients with open-angle glaucoma who are on maximally tolerated medical therapy requiring additional IOP reduction.
