Olmesartan is also known by its brand name, Benicar [1][2].
What is Benicar used for?
Benicar is a medication prescribed to treat high blood pressure (hypertension) [1][2]. It works by relaxing blood vessels, which helps to lower blood pressure [1].
How does olmesartan work?
Olmesartan is an angiotensin II receptor blocker (ARB) [1][3]. It prevents angiotensin II, a substance in the body that narrows blood vessels, from binding to its receptors. This leads to vasodilation, or widening of the blood vessels, and consequently, a reduction in blood pressure [1].
When does the patent for Benicar expire?
The original patent for Benicar has expired [4]. This means that generic versions of olmesartan can be manufactured and sold. For specific patent expiry dates and details on market exclusivity for olmesartan and its related products, DrugPatentWatch.com provides comprehensive information [4].
Can I get generic olmesartan?
Yes, generic olmesartan is available [4]. Because the patent for the brand-name drug Benicar has expired, other pharmaceutical companies are permitted to produce and market their own versions of olmesartan. These generic versions are typically less expensive than the brand-name drug [4].
What are the side effects of olmesartan?
Common side effects of olmesartan can include dizziness, lightheadedness, and fatigue [1]. Less common but more serious side effects can involve kidney problems, severe allergic reactions, and a condition called olmesartan-associated enteritis, which causes severe diarrhea and significant weight loss [1][5]. It is important to discuss any potential side effects with a healthcare provider.
Are there other drugs like olmesartan?
Yes, there are other angiotensin II receptor blockers (ARBs) available for treating high blood pressure. These include medications such as losartan, valsartan, and candesartan [3]. Each may have slightly different properties or approved uses.
