A hypeensive patient presented with open-angle glaucoma. Drug of choice is to decrease the IOP is:
Timolol is a potent, non-selective beta receptor antagonist. It has no intrinsic sympathomimetic or membrane-stabilizing activity. It is used for hypeension, congestive hea failure, acute MI, and migraine prophylaxis. It is used in the treatment of open-angle glaucoma and intraocular hypeension. Its mechanism of action in treating open angle glaucoma is not precisely known; but the drug appears to reduce aqueous humour production through blockade of beta receptors on the ciliary epithelium.
