PRESCRIPTION DRUG
Hydrochlorothiazide is indicated as adjunctive therapy in edema associated with congestive heart failure, hepatic cirrhosis, and corticosteroid and estrogen therapy. Hydrochlorothiazide has also been found useful in edema due to various forms of renal dysfunction such as nephrotic syndrome, acute glomerulonephritis, and chronic renal failure. Hydrochlorothiazide is indicated in the management of hypertension either as the sole therapeutic agent or to enhance the effectiveness of other antihypertensive drugs in the more severe forms of hypertension. Use in Pregnancy. 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. Edema during pregnancy may arise from pathologic causes or from the physiologic and mechanical consequences of pregnancy. Thiazides are indicated in pregnancy when edema is due to pa

Abbreviated New Drug Application
HYDROCHLOROTHIAZIDE- HYDROCHLOROTHIAZIDE TABLET HERITAGE PHARMACEUTICALS INC. ---------- HYDROCHLOROTHIAZIDE TABLETS, USP RX ONLY DESCRIPTION Hydrochlorothiazide is a diuretic and antihypertensive. It 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 CIN O S and its structural formula is: It is a white, or practically white, crystalline powder with a molecular weight of 297.74 which is slightly soluble in water, freely soluble in sodium hydroxide solution, in n-butylamine and in dimethylformamide; sparingly soluble in methanol; insoluble in ether, in chloroform and in dilute mineral acids. Hydrochlorothiazide is supplied as 25 mg and 50 mg tablets for oral use. Each tablet contains the following inactive ingredients: lactose anhydrous, pregelatinized starch, sodium starch glycolate, magnesium stearate, D&C Yellow #10 Lake, and FD&C Red #40 Lake. 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 efficacy. 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.
