Routine use of diuretics during normal pregnancy is inappropriate and exposes mother and fetus to unnecessary hazard. Diuretics do not prevent development of toxemia of pregnancy and there is no satisfactory evidence that they are useful in the treatment of toxemia.

DESCRIPTION
Hydrochlorothiazide USP is a diuretic and antihypertensive. It is the
3,4-dihydro derivative of
chlorothiazide. It is chemically designated as
6-chloro-3,4-dihydro-2_H_-1,2,4-benzothiadiazine-7-
sulfonamide 1,1-dioxide and has the following structural formula:
C H CIN O S M.W. 297.74
Hydrochlorothiazide USP is a white, or practically white, crystalline
powder which is slightly soluble
in water, but freely soluble in sodium hydroxide solution. Each tablet
for oral administration contains 25
mg or 50 mg hydrochlorothiazide USP. In addition, each tablet contains
the following inactive
ingredients: FD&C yellow #6, Microcrystalline cellulose, lactose,
Sodium starch glycolate, Stearic
acid and magnesium stearate.
CLINICAL PHARMACOLOGY
The mechanism of the antihypertensive effect of thiazides is unknown.
Hydrochlorothiazide does not
usually affect normal blood pressure.
Hydrochlorothiazide affects the distal renal tubular mechanism of
electrolyte reabsorption. At maximal
therapeutic dosage all thiazides are approximately equal in their
diuretic efcacy.
Hydrochlorothiazide increases excretion of sodium and chloride in
approximately equivalent amounts.
Natriuresis may be accompanied by some loss of potassium and
bicarbonate.
After oral use diuresis begins within 2 hours, peaks in about 4 hours
and lasts about 6 to 12 hours.
PHARMACOKINETICS AND METABOLISM
Hydrochlorothiazide is not metabolized but is eliminated rapidly by
the kidney. When plasma levels
have been followed for at least 24 hours, the plasma half-life has
been observed to vary between 5.6
and 14.8 hours. At least 61 percent of the oral dose is eliminated
unchanged within 24 hours.
Hydrochlorothiazide crosses the placental but not the blood-brain
barrier and is excreted in breast milk.
INDICATIONS AND USAGE
Hydrochlorothiazide USP is indicated as adjunctive therapy in edema
associated with congestive heart
failure, hepatic cirrhosis
