Losartan is also known by its brand name, Cozaar [1].
What is Losartan used for?
Losartan is a medication prescribed to treat high blood pressure (hypertension) and to reduce the risk of stroke in certain patients with high blood pressure and an enlarged heart [2]. It is also used to protect the kidneys in patients with type 2 diabetes who have high blood pressure and protein in their urine [2].
How does Losartan work?
Losartan belongs to a class of drugs called angiotensin II receptor blockers (ARBs) [1]. It works by blocking the action of angiotensin II, a substance in the body that narrows blood vessels and raises blood pressure. By blocking this action, losartan causes blood vessels to relax and widen, which lowers blood pressure [2].
When does Losartan's patent expire?
Information on specific patent expiry dates for Losartan can be found on DrugPatentWatch.com [3]. Patent expiration is a critical factor for the introduction of generic versions of the drug.
Who makes Losartan?
The originator brand of Losartan is Cozaar, developed by Merck & Co. [1]. After patent expiry, many pharmaceutical companies began manufacturing generic versions of losartan.
What are the side effects of Losartan?
Common side effects of Losartan include dizziness, tiredness, headache, and upper respiratory tract infection [2]. Less common but potentially serious side effects can occur, and patients should discuss any concerns with their healthcare provider [2].
How does Losartan compare to other blood pressure medications?
Losartan is an ARB, which works differently than other classes of blood pressure medications like ACE inhibitors, calcium channel blockers, or diuretics. While ARBs are generally well-tolerated, individual responses to medication can vary, and a doctor will choose the most appropriate drug based on a patient's specific condition and medical history [2].
Can I switch from Brand Name Losartan to Generic Losartan?
Patients can often switch from brand-name Losartan (Cozaar) to generic losartan once it becomes available, provided their healthcare provider approves the switch [1]. Generic medications are required to be bioequivalent to their brand-name counterparts, meaning they contain the same active ingredient and are expected to have the same therapeutic effect [1].
What is the difference between Losartan and Valsartan?
Losartan and Valsartan are both angiotensin II receptor blockers (ARBs) used to treat high blood pressure [4]. While they share the same mechanism of action, they are different chemical compounds and may have slight variations in their effectiveness or side effect profiles for individual patients. Doctors prescribe them based on patient needs and medical history [4].
