Metoprolol tartrate is a widely used medication prescribed to treat high blood pressure and heart conditions [1]. It is available in generic form and is often prescribed to manage symptoms like chest pain, irregular heartbeats, and heart failure [2].
What is the difference between metoprolol tartrate and metoprolol succinate?
Metoprolol tartrate and metoprolol succinate are both forms of metoprolol, but they differ in their release mechanisms [3]. Metoprolol tartrate is an immediate-release formulation, meaning it takes effect relatively quickly and requires multiple daily doses [4]. Metoprolol succinate, on the other hand, is an extended-release formulation that gradually releases the medication over a longer period, allowing for once-daily dosing [4].
How does metoprolol work?
Metoprolol belongs to a class of drugs called beta-blockers [1]. It works by blocking the effects of certain hormones, such as adrenaline, on the heart and blood vessels [1]. This action causes the heart to beat more slowly and with less force, which lowers blood pressure and reduces the heart's workload [1].
When does the patent for metoprolol expire?
As metoprolol tartrate has been available for many years, its original patents have long since expired, allowing for its widespread availability as a generic medication [5]. Information on specific patent expirations for older drugs like metoprolol can often be found on specialized patent tracking websites [5].
What are the common side effects of metoprolol?
Common side effects of metoprolol can include fatigue, dizziness, slowed heart rate, and cold hands and feet [6]. Some individuals may also experience shortness of breath or gastrointestinal issues [6]. It is important for patients to discuss any side effects with their healthcare provider [6].
Who manufactures generic metoprolol?
Numerous pharmaceutical companies manufacture generic versions of metoprolol tartrate, contributing to its accessibility and affordability [7].
