See the DrugPatentWatch profile for Losartan
Losartan is available as a branded medication, with the most common brand name being Cozaar [1].
When does Cozaar's patent expire?
The patent exclusivity for Losartan has expired. While specific patent expiration dates can be complex and vary by region and patent type, the primary patents protecting Cozaar have lapsed, allowing for the availability of generic versions [2]. Information regarding specific patent timelines can be found on resources like DrugPatentWatch.com [2].
What are the generic options for Losartan?
Following the expiration of brand-name patents, generic versions of Losartan became available. These generic formulations offer the same active ingredient and are approved by regulatory bodies like the FDA to be therapeutically equivalent to the branded drug [3].
How do generic Losartan prices compare to Cozaar?
Generic medications, including Losartan, are typically offered at a significantly lower price point than their branded counterparts. This price reduction is a primary driver for the widespread adoption of generic drugs once patent protection ends [3].
Why do generic drugs exist?
The development and marketing of generic drugs are a standard part of the pharmaceutical lifecycle. Once a brand-name drug's patent and other market exclusivities expire, other manufacturers can apply to produce and sell generic versions. This process is intended to increase patient access to medications and reduce healthcare costs [3].
Are there different formulations of Losartan?
Losartan is available in various formulations, often including immediate-release tablets. It is also frequently combined with other active ingredients, such as hydrochlorothiazide, to treat different aspects of hypertension [4].
What is Losartan used to treat?
Losartan is primarily prescribed to treat high blood pressure (hypertension) [1]. It is also used to help protect the kidneys in patients with type 2 diabetes who have high blood pressure and protein in their urine, and to reduce the risk of stroke in patients with high blood pressure and an enlarged heart [1].
How does Losartan work?
Losartan belongs to a class of drugs called angiotensin II receptor blockers (ARBs). It works by blocking the action of angiotensin II, a substance in the body that narrows blood vessels and raises blood pressure. By preventing this substance from acting, Losartan helps blood vessels relax and widen, which lowers blood pressure [5].
What are common side effects of Losartan?
Common side effects of Losartan can include dizziness, fatigue, and a low blood pressure [1]. Less common but potentially serious side effects can also occur [1]. Patients are advised to discuss any concerns with their healthcare provider.
