-selective (cardioselective) adrenergic receptor blocking
agent available as 10-mg and 20-mg tablets for oral administration.

[4-[2-(cyclopropylmethoxy)
ethyl] phenoxy]-3-[(1-methylethyl) amino]-, hydrochloride, (±)-. It

chemical structure:
Each tablet for oral administration contains 10 mg or 20 mg of

H
NO
•HCl and a molecular weight of 343.9. It is freely soluble in

CLINICAL PHARMACOLOGY:
Betaxolol is a ß
-selective (cardioselective) adrenergic receptor blocking agent that
has
weak membrane-stabilizing activity and no intrinsic sympathomimetic
(partial agonist)
activity. The preferential effect on ß
receptors is not absolute, however, and some
inhibitory effects on ß
receptors (found chiefly in the bronchial and vascular
musculature) can be expected at higher doses.
PHARMACOKINETICS AND METABOLISM: In man, absorption of an oral dose is
complete.
There is a small and consistent first-pass effect resulting in an
absolute bioavailability of
89% ± 5% that is unaffected by the concomitant ingestion of food or
alcohol. Mean
peak blood concentrations of 21.6 ng/ml (range 16.3 to 27.9 ng/ml) are
reached
between 1.5 and 6 (mean about 3) hours after a single oral dose, in
healthy volunteers,
of 10 mg of betaxolol. Peak concentrations for 20-mg and 40-mg doses
are 2 and 4
times t
