Overview
Acetan HCT 100/25mg Tablet is a combination tablet containing losartan 100mg, an angiotensin II receptor blocker (ARB), and hydrochlorothiazide 25mg, a thiazide diuretic (‘water pill’). It is used to treat high blood pressure that is not adequately controlled by either medicine alone.
Losartan relaxes blood vessels by blocking the hormone angiotensin II, while hydrochlorothiazide helps the kidneys remove extra salt and water from the body. Together, these two mechanisms provide a stronger blood-pressure-lowering effect than either medicine used on its own.
How it Works
Losartan selectively blocks the AT1 receptor, preventing angiotensin II from narrowing blood vessels and triggering aldosterone-driven salt retention. Hydrochlorothiazide acts on the distal renal tubule to reduce sodium and water reabsorption, increasing urine output. The combined vasodilation and reduced fluid volume produce an additive drop in blood pressure.
Directions for Use
Take Acetan HCT 100/25mg Tablet in the morning where possible, as the diuretic component can increase urination and may disturb sleep if taken late in the day. It can be taken with or without food, at the same time each day.
Dosage
Acetan HCT 100/25mg Tablet is usually taken once daily, with your doctor selecting the appropriate strength based on your blood pressure response and how well you tolerate the medicine. Do not change between strengths without your doctor’s advice.

Drug / Food Interactions
- Potassium supplements or potassium-sparing diuretics may raise blood potassium when combined with losartan, while hydrochlorothiazide can lower it – your doctor will monitor your electrolytes

- Lithium levels may increase when combined with either component
- Other blood pressure medicines may increase the risk of low blood pressure

- Attend scheduled blood tests to monitor your kidney function and electrolyte (sodium/potassium) levels
