What is this pain killer called?

Question

Given its physical and visual description.

Answer 1

Indapamide-blood pressure

Answer 2

indapamide is actually a diuretic that can be used for hypertension (HTN or high blood pressure).  It's main use is to help prevent the body from absorbing too much sodium (salt), which can cause fluid retention (edema).  The brand name is Lozol.  While indapamide does have a capital A on one side, it has the number "3" imprinted on the opposite side.  It is NOT a pain killer.
