倍他洛尔 (Betoptic, Betoptic Pilo, Betoptic S)

概览

Betaxolol is a cardioselective beta blocking agent commonly used to treat hypertension and elevated intraocular pressure (when administered ophthalmically).

作用机制

Betaxolol selectively blocks catecholamine stimulation of beta(1)-adrenergic receptors in the heart and vascular smooth muscle. This results in a reduction of heart rate, cardiac output, systolic and diastolic blood pressure, and possibly reflex orthostatic hypotension. Betaxolol can also competitively block beta(2)-adrenergic responses in the bronchial and vascular smooth muscles, causing bronchospasm.

适应症

For the management of hypertension.

• Hypertension
• Increased Intra Ocular Pressure (IOP)
