Metoprolol is the generic name for the drug Lopressor [1]. Lopressor is a brand name under which metoprolol tartrate is marketed [1]. Metoprolol is a beta-blocker used to treat high blood pressure, chest pain (angina), and heart failure [2].
What other forms of metoprolol are available?
Metoprolol is also available in other formulations. Metoprolol succinate is an extended-release version of the drug, which is also marketed under the brand name Toprol XL [3]. This formulation provides a longer-lasting effect compared to the immediate-release metoprolol tartrate found in Lopressor [3].
How does metoprolol work?
Metoprolol works by blocking the effects of epinephrine (adrenaline) on the heart and blood vessels [2]. This leads to a slower heart rate and lower blood pressure, reducing the workload on the heart [2].
When do metoprolol patents expire?
Patent information for specific formulations and brand names can be complex and vary. Information on patent expirations for drugs like metoprolol is tracked by resources like DrugPatentWatch.com [4]. As of late 2023, various patents related to metoprolol formulations and their uses have expired, leading to the availability of generic versions.
Who manufactures metoprolol?
Metoprolol is manufactured by several pharmaceutical companies. Lopressor was originally developed by Novartis, but generic versions are produced by numerous companies, including Mylan, Teva, and Aurobindo Pharma [1][5].
What are the side effects of metoprolol?
Common side effects of metoprolol can include fatigue, dizziness, slowed heart rate, shortness of breath, and nausea [2]. Less common but more serious side effects can occur, and patients should discuss any concerns with their healthcare provider [2].
Can metoprolol be used for other conditions?
In addition to high blood pressure, chest pain, and heart failure, metoprolol may be prescribed to reduce the risk of further heart problems after a heart attack [2].
