Wskazania:

Hydrochlorothiazide capsules are indicated in th management of hypertension either as the sole therapeutic agent, or in combination with other antihypertensives. Unlike potassium sparing combination diuretic products, hydrochlorothiazide capsules may be used in those patients in whom the development of hyperkalemia cannot be risked, including patients taking ACE inhibitors. The routine use of diuretics in an otherwise healthy woman 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 developed toxemia. Edema during pregnancy may arise from pathological causes or from the physiologic and mechanical consequences of pregnancy. Diuretics are indicated in pregnancy when edema is due to pathologic causes, just as they are in the absence of pregnancy. Dependent edema in pregnancy resulting from restriction of venous return by the expanded uterus is properly trea

HYDROCHLOROTHIAZIDE CAPSULES, USP

DESCRIPTION
Hydrochlorothiazide (hydrochlorothiazide, USP 12.5 mg) is the
3,4-dihydro derivative of
chlorothiazide. Its chemical name is
6-chloro-3,4-dihydro-2_H_-1,2,4-benzothiadiazine-7-
sulfonamide 1,1-dioxide. Its empirical formula is C H ClN O S ; its
molecular weight is
297.74; and its structural formula is:
It is a white, or practically white, crystalline powder which is
slightly soluble in water, but
freely soluble in sodium hydroxide solution.
Hydrochlorothiazide capsules, USP are supplied as 12.5 mg capsules for
oral use.
Inactive ingredients: colloidal silicon dioxide, corn starch, lactose
monohydrate,
magnesium stearate. The hard gelatin shell consists of gelatin,
titanium dioxide, sodium
lauryl sulfate, FD&C Blue #1, FD&C Red #3. The capsules are printed
with black ink
containing shellac, dehydrated alcohol, isopropyl alcohol, butyl
alcohol, propylene glycol,
strong ammonia solution, black iron oxide, and potassium hydroxide.
CLINICAL PHARMACOLOGY
Hydrochlorothiazide blocks the reabsorption of sodium and chloride
ions, and it thereby
increases the quantity of sodium traversing the distal tubule and the
volume of water
excreted. A portion of the additional sodium presented to the distal
tubule is exchanged
there for potassium and hydrogen ions. With continued use of
hydrochlorothiazide and
depletion of sodium, compensatory mechanisms tend to increase this
exchange and
may produce excessive loss of potassium, hydrogen and chloride ions.
Hydrochlorothiazide also decreases the excretion of calcium and uric
acid, may increase
the excretion of iodide and may reduce glomerular filtration rate.
Metabolic toxicities
associated with excessive electrolyte changes caused by
hydrochlorothiazide have been
shown to be dose-related.
PHARMACOKINETICS AND METABOLISM
Hydrochlorothiazide is well absorbed (65% to 75%) following oral
administration.
