DESCRIPTION
Triamterene and hydrochlorothiazide tablets combine triamterene, a
potassium-conserving diuretic with
the natriuretic agent hydrochlorothiazide. Each tablet for oral
administration contains 37.5 mg
triamterene and 25 mg hydrochlorothiazide or 75 mg triamterene and 50
mg hydrochlorothiazide.
Inactive ingredients include croscarmellose sodium, D & C Yellow #10
Aluminum Lake,
hydroxypropyl methylcellulose, magnesium stearate, microcrystalline
cellulose, polysorbate 80, and
sodium bicarbonate. The 37.5 MG/25 MG tablet also contains FD & C Blue

formic acid and sparingly soluble in
methoxyethanol. Triamterene is very slightly soluble in acetic acid,
alcohol and dilute mineral acids. Its
molecular weight is 253.27. Its structural formula is:

CLINICAL PHARMACOLOGY
Triamterene and hydrochlorothiazide is a diuretic, antihypertensive
drug product, principally due to its
hydrochlorothiazide component; the triamterene component reduces the
excessive potassium loss which

Triamterene is a potassium conserving (antikaliuretic) diuretic with

exchange for potassium and hydrogen. With this action, triamterene
