Indapamide

The most significant modifiable risk factor for cardiovascular disease and the most prominent contributor to all-cause mortality is hypertension. Characterized by an office blood pressure of ≥140/90, hypertension is pervasive and impacts an estimated 25% of adults globally. Treatment for hypertension should include a number of lifestyle changes (ie. reduced sodium intake) along with pharmacotherapy - it should be noted that treatment with several antihypertensive agents may be required in order to achieve blood pressure targets.

Thiazide-like diuretics such as indapamide are a valuable tool for the treatment of hypertension and continue to grow in popularity, falling behind only ACE inhibitors in terms of prescription frequency. When compared to hydrochlorothiazide (another commonly prescribed diuretic), indapamide has been shown to be superior at lowering systolic blood pressure, reducing left ventricular mass index, lowering oxidative stress, inhibiting platelet aggregation, and reducing microalbuminuria associated with diabetes. Interestingly, unlike thiazide diuretics, several sources suggest that indapamide is not associated with glucose or lipid disturbances.

Indapamide is characterized by both a methylindoline and a sulfamoyl chlorobenzamide functional group, with the former being largely responsible for the molecule’s lipid solubility.

Indapamide is a diuretic indicated for use as monotherapy or in combination with other blood pressure-lowering agents to treat hypertension. It may also be used to treat fluid and salt retention associated with congestive heart failure.
