What is Olmesartan?
Olmesartan belongs to a class of medications called angiotensin II receptor blockers. By blocking the hormone that causes vessels to tighten, it allows blood to flow more easily. Healthcare providers often recommend this medication as part of a wider strategy for the Heart & Blood Pressure category to reduce strain on the cardiovascular system.
How does Olmesartan work?
The body naturally produces a substance that constricts and narrows blood vessels. Olmesartan prevents this substance from accessing its receptor sites. Consequently, vessels relax and widen, allowing blood to circulate with less resistance. This process eases the workload on the heart and keeps blood pressure at a more sustainable level.
Olmesartan brands and forms
Original medications include brands such as Sevikar, Olmetec, Ometec, and Olmesartanplus, while popular catalogue listings feature Azor, Benicar, Benicar HCT, and Tribenzor. These are typically manufactured as a film-coated tablet for stable release. When comparing options, you may find that some contain Olmesartan alone, while others combine it with additional ingredients to provide multi-action support for arterial health.
