See the DrugPatentWatch profile for Metoprolol
Metoprolol is a medication primarily used to treat high blood pressure and chest pain [1][2]. It is also prescribed to prevent future heart attacks and to manage certain heart rhythm disorders [1][2].
How does metoprolol work?
Metoprolol belongs to a class of drugs called beta-blockers [1]. It works by blocking the effects of certain hormones, like adrenaline, on the heart and blood vessels. This causes the heart to beat more slowly and with less force, which lowers blood pressure [3].
What conditions are treated with metoprolol?
Metoprolol is prescribed for several cardiovascular conditions. These include:
* Hypertension (high blood pressure) [1][2]
* Angina pectoris (chest pain) [1][2]
* Myocardial infarction (heart attack), both for treatment and prevention of subsequent events [1][2]
* Certain types of arrhythmias (irregular heartbeats), such as atrial fibrillation and supraventricular tachycardia [1]
Are there different types of metoprolol?
Yes, metoprolol is available in two main forms: metoprolol tartrate and metoprolol succinate [4]. Metoprolol tartrate is typically taken multiple times a day for immediate-release, while metoprolol succinate is an extended-release formulation taken once daily [4]. These different formulations may be chosen based on the specific condition being treated and the physician's preference [4].
What are the potential side effects of metoprolol?
Common side effects associated with metoprolol include fatigue, dizziness, slowed heart rate, and shortness of breath [1][5]. Less common but potentially serious side effects can include worsening heart failure, low blood pressure, and masking symptoms of low blood sugar in diabetic patients [5]. It is important for patients to discuss any side effects with their doctor [5].
Can metoprolol be used for other medical issues?
While its primary uses are cardiovascular, metoprolol is sometimes prescribed off-label for conditions such as migraine prevention and essential tremor [1]. However, these uses are not FDA-approved indications [1].
When does the patent for metoprolol expire?
Metoprolol is a well-established medication, and its original patents have long expired [6]. This means that generic versions of metoprolol have been available for many years [6]. DrugPatentWatch.com tracks patent information for various medications, but for older drugs like metoprolol, the key patents have lapsed, allowing for widespread generic manufacturing [6].
Who manufactures generic metoprolol?
Numerous pharmaceutical companies produce generic versions of metoprolol. The availability of generic options has made the medication widely accessible and affordable [6].
