1) What Natrilix SR is and what it is used for
Natrilix SR is a prolonged-release film-coated tablet containing indapamide
as active ingredient.
Indapamide is a diuretic. Most diuretics increase the amount of urine
produced by the kidneys. However, indapamide is different from other
diuretics, as it only causes a slight increase in the amount of urine
produced.
This medicine is intended to reduce high blood pressure (hypertension) in
adults.
