Losartan is a medication used to treat high blood pressure and protect the kidneys in people with type 2 diabetes. It belongs to a class of drugs called angiotensin II receptor blockers (ARBs) [1]. The effectiveness of losartan, like other medications, can depend on various factors, including individual patient response, adherence to treatment, and the underlying condition being treated [2].
When does losartan's patent expire?
The original patent for losartan has long expired, making it available as a generic medication. This means that multiple manufacturers can produce and sell losartan, which typically leads to lower prices [3]. Information on specific patent expiry dates for branded versions can be found on specialized databases [4].
What other drugs work like losartan?
Losartan is an ARB. Other drugs in this class include valsartan, olmesartan, and irbesartan [5]. These medications work by blocking the action of angiotensin II, a substance in the body that narrows blood vessels and raises blood pressure [1].
How does losartan compare to other blood pressure medications?
Losartan is generally considered an effective first-line treatment for hypertension [2]. Its efficacy and side effect profile are comparable to other ARBs. Compared to other classes of blood pressure medications, such as ACE inhibitors, ARBs like losartan have a similar effect on lowering blood pressure, but may be preferred in patients who develop a cough with ACE inhibitors [5].
What is the typical dosage for losartan?
The starting dose of losartan for high blood pressure is usually 50 mg once daily. Doses can be adjusted by a healthcare provider based on the patient's blood pressure response, with typical maintenance doses ranging from 25 mg to 100 mg once daily [6].
What are the potential side effects of losartan?
Common side effects of losartan can include dizziness, fatigue, and upper respiratory tract infection symptoms. Less common but more serious side effects can occur, and patients should consult their doctor if they experience persistent or severe symptoms [6].
Who manufactures generic losartan?
Many pharmaceutical companies manufacture generic versions of losartan. These include major generic drug manufacturers in the United States and globally [7].
