Table of contents:

Atacand HCT is a prescription medication that is used to treat high blood pressure (hypertension) and swelling (edema). It is a combination of two active ingredients: candesartan cilexetil and hydrochlorothiazide.

Candesartan cilexetil is an angiotensin II receptor antagonist, which means it helps to relax blood vessels and improve blood flow by blocking the action of a hormone called angiotensin II. Angiotensin II is a natural substance in the body that causes blood vessels to narrow and can raise blood pressure.

On the other hand, hydrochlorothiazide is a thiazide diuretic that helps the body get rid of excess water and salt through urine. By combining these two medications, Atacand HCT can help lower blood pressure and decrease fluid accumulation in the body, which can help treat conditions such as hypertension and edema.

Use and Dosage

Atacand HCT (Candesartan/HCTZ) is available in tablet form and should be taken orally, with or without food, as directed by your doctor. Typically, it is taken once daily. Avoid taking Atacand HCT within 4 hours of bedtime to avoid the need to urinate during the night.

The recommended dosage of Atacand HCT (candesartan/hydrochlorothiazide) depends on the individual's medical condition and response to treatment. Generally, the usual recommended starting dose of candesartan cilexetil is 16 mg once daily, and the dosage range for hydrochlorothiazide is between 12.5 mg to 25 mg once daily. The optimum therapeutic effect is expected within 4 weeks.
