ACTION AND CLINICAL PHARMACOLOGY
Betaxolol is a cardioselective (beta-1-adrenergic) receptor blocking
agent. It does not have significant
membrane-stabilizing (local anesthetic) activity and is devoid of
intrinsic sympathomimetic action.
OCULAR:
When instilled in the eye, betaxolol reduces elevated as well as
normal intraocular pressure, whether or
not accompanied by glaucoma. When used as a solution, the onset of
action occurs within 30 minutes
and the maximal effect is usually attained approximately two hours
after instillation. Although the time
of onset of action, and time of maximal effect for the suspension have
not been determined, controlled
double masked studies show that the magnitude and duration of the
ocular hypotensive effect of betaxolol
0.5% solution and BETOPTIC
*
S 0.25% suspension were clinically equivalent.
A single dose provides a 12-hour reduction in intraocular pressure and
twice daily administration
maintains the IOP below 22 mmHg in most patients. Betaxolol has no
effect on pupil size or
accommodation.

metabolized mainly
