Contents of the pack
This medication contains two active ingredients, enalapril and hydrochlorothiazide, which belong to the group of antihypertensives and, by different mechanisms, reduce high blood pressure.
The enalapril component is a medication that belongs to a group of medications known as angiotensin-converting enzyme inhibitors (ACE inhibitors), which acts by dilating blood vessels to make the heart pump blood to all parts of the body more easily. The hydrochlorothiazide component belongs to the group of medications known as thiazide diuretics (medications that increase urine elimination). Together, enalapril and hydrochlorothiazide help reduce high blood pressure.
Your doctor has prescribed this medication to treat hypertension (high blood pressure) because it is not adequately controlled with enalapril or an ACE inhibitor alone.
