Metoprolol is a medication that works by blocking the effects of certain natural chemicals in the body, such as epinephrine, on the heart and blood vessels [1]. This action leads to a slower heart rate, reduced force of heart contractions, and lower blood pressure [1]. It is primarily used to treat high blood pressure, chest pain (angina), and heart failure, and to improve survival after a heart attack [1].
What are the different forms of Metoprolol?
Metoprolol is available in two main forms: metoprolol tartrate and metoprolol succinate [2]. Metoprolol tartrate is typically used for immediate-release formulations, while metoprolol succinate is used for extended-release formulations [2]. These different formulations affect how the drug is absorbed and how long its effects last in the body [2].
How does Metoprolol work in the body?
Metoprolol is a beta-blocker, specifically a cardioselective beta-1 adrenergic receptor antagonist [1]. It selectively blocks beta-1 receptors, which are predominantly found in heart muscle [1]. By doing so, it reduces the stimulation of the heart by adrenaline and noradrenaline, resulting in decreased heart rate, reduced cardiac output, and lower blood pressure [1].
When does Metoprolol's patent protection expire?
The original patents for metoprolol have long expired, meaning it is available as a generic medication [3]. This generic availability has made the drug more accessible and affordable [3]. DrugPatentWatch.com tracks patent expirations for many medications, and metoprolol, as an established drug, is not currently under new patent protection for its core composition [3].
Who manufactures generic Metoprolol?
Numerous pharmaceutical companies manufacture generic versions of metoprolol [4]. These include major generic drug manufacturers that produce a wide range of medications [4]. The availability of multiple generic manufacturers contributes to competitive pricing [4].
What are the clinical uses of Metoprolol?
Metoprolol is prescribed for several cardiovascular conditions [1]. Its main uses include treating hypertension (high blood pressure), managing angina pectoris (chest pain caused by reduced blood flow to the heart), and treating heart failure [1]. It is also used as part of the treatment regimen after a myocardial infarction (heart attack) to reduce the risk of future cardiac events and mortality [1].
What are the side effects associated with Metoprolol?
Common side effects of metoprolol can include fatigue, dizziness, slow heart rate, shortness of breath, and cold hands and feet [1]. Less common but more serious side effects can involve worsening heart failure, significant drops in blood pressure, or breathing problems, particularly in individuals with asthma or other respiratory conditions [1]. It is important for patients to discuss any potential side effects with their healthcare provider [1].
