Benicar (olmesartan): Benicar (olmesartan) is an angiotensin receptor binder or arb anti-hypertensive. It is absorbed and quickly metabolised in the gut. On average the drug should begin working within 20-40 minutes of ingestion. It works on a complex feedback system and can take up to two weeks before seeing any effects on your blood pressure. After two weeks your doctor may decide to adjust the dose if no benefits are seen.

About 3 days: The half life if Benicar (olmesartan) is 13 hours and a drug takes five half lifes to reach a steady state in the blood stream. That makes it 65 hours or approx 3 days.
