Apraclonidine hydrochloride (ALO 2145) is more commonly used topically for glaucoma, as it penetrates the cornea and blood-brain barrier to a lesser extent and, thus, has fewer adverse systemic effects.
体内研究
Apraclonidine hydrochloride (ALO 2145) is effective in animal models of elevated IOP as well as glaucoma in humans. The ocular hypotensive effects of Apraclonidine are usually attributed to reduced aqueous humor synthesis and vasoconstrictor actions at the anterior segment branches of the ophthalmic artery.
