Background: Angiotensin II type 1 (AT 1) receptor antagonist (angiotensin receptor blocker [ARB]) called Olmesartan medoxomil (OLM) prevents angiotensin II from acting on the renin-angiotensin-aldosterone pathway, which is a crucial factor in the development of hypertension. OLM is reported to rapidly hydrolyze into its active metabolite, Olmesartan, in plasma after oral treatment.
Objective: The objective of the ongoing study was to develop an easy-to-use, precise, and reliable RP-HPLC method for the determination of Olmesartan in bulk as well as pharmaceutical dosage forms.
