Hydrochlorothiazide           25 mg

Pharmacological Actions:-
Hydrochlorothiazide is a diuretic and antihypertensive agent. It affects the distal renal tubular mechanism of electrolyte reabsorption.

Hydrochlorothiazide is not metabolized but is eliminated rapidly by the kidney.
At least 61% 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.
Hydrex is indicated as adjunctive therapy in edema associated with congestive heart failure, hepatic cirrhosis, and corticosteroid and estrogen therapy.
It is indicated in the management of hypertension either as the sole therapeutic agent or to enhance the effectiveness of other antihypertensive drugs.

Anuria, hypersensitivity to hydrochlorothiazide or to other sulfonamide derived drugs.

Use with caution in sever renal disease and in patients with impaired hepatic function. Hypokalemia may be avoided or treated by use of potassium sparing diuretics or potassium supplements such as foods with a high potassium content.

Warning signs of fluid and electrolyte impalance include weakness, hypotension, diarrhea, nausea, cramping, anemia and renal dysfunction.

Drug interactions:-
