Diazide 80mg (100 tablets) contains a combination of Hydrochlorothiazide and Spironolactone. This medication is used to treat high blood pressure (hypertension) and edema (fluid retention) caused by conditions such as heart failure and kidney disease. Hydrochlorothiazide is a thiazide diuretic that helps reduce fluid retention by increasing urine output, while Spironolactone is a potassium-sparing diuretic that helps maintain potassium levels. The combination of these two drugs helps manage blood pressure and fluid balance.
