Losartan potassium is manufactured by several pharmaceutical companies. These include Merck & Co., Inc. (as the original developer under the brand name Cozaar), and numerous generic manufacturers.
Who makes generic Losartan potassium?
A wide range of generic pharmaceutical companies produce losartan potassium. These companies typically manufacture the drug after the original patent expires, making it available at a lower cost. Some prominent manufacturers of generic losartan potassium include Teva Pharmaceuticals, Mylan N.V. (now part of Viatris), Aurobindo Pharma, and Accord Healthcare, among others [1].
When does patent exclusivity end for Losartan?
The patent exclusivity for losartan potassium, originally developed by Merck & Co., Inc. as Cozaar, has long since expired. This allowed for the introduction of generic versions into the market. DrugPatentWatch.com tracks patent expirations for pharmaceuticals, and losartan's primary patents have been expired for many years, enabling widespread generic production [2].
What is the difference between Cozaar and generic Losartan?
Cozaar is the brand-name version of losartan potassium, originally developed and marketed by Merck & Co., Inc. Generic losartan potassium contains the same active ingredient, losartan potassium, and is bioequivalent to Cozaar. This means it has the same dosage, safety, and effectiveness. The primary difference lies in the inactive ingredients and the cost, with generic versions typically being significantly less expensive than the brand-name drug [3].
Are there any safety concerns with Losartan potassium?
In the past, some manufacturers of losartan potassium faced recalls due to the presence of N-nitroso-N-methyl-4-propylamine (NMPA) and N-nitroso-diisopropylamine (NDIPA) impurities. These impurities were found in certain batches of the drug and were linked to potential carcinogenic risks. Regulatory bodies, such as the U.S. Food and Drug Administration (FDA), worked with manufacturers to identify the source of these impurities and ensure that products on the market met safety standards [4].
How is Losartan potassium used?
Losartan potassium is a medication primarily used to treat high blood pressure (hypertension). It belongs to a class of drugs called angiotensin II receptor blockers (ARBs). ARBs work by blocking the action of angiotensin II, a substance in the body that narrows blood vessels and raises blood pressure. Losartan potassium is also prescribed to reduce the risk of stroke in patients with high blood pressure and left ventricular hypertrophy, and to protect kidney function in patients with type 2 diabetes and hypertension [5].
