Metoprolol tartrate 25 mg is a specific dosage of a prescription medication used to treat various cardiovascular conditions. It belongs to a class of drugs known as beta-blockers.
What is Metoprolol Tartrate Used For?
Metoprolol tartrate is prescribed to manage high blood pressure (hypertension), chest pain (angina), and to improve survival after a heart attack [1]. It works by slowing the heart rate and reducing the force with which the heart pumps blood, which lowers blood pressure [1].
How Does Metoprolol Tartrate Work?
As a selective beta-1 adrenergic receptor blocker, metoprolol tartrate primarily affects the heart. By blocking the action of adrenaline and noradrenaline on these receptors, it decreases heart rate, reduces myocardial contractility, and lowers blood pressure [2]. This action helps to reduce the workload on the heart.
What Are the Common Dosages of Metoprolol Tartrate?
Dosages of metoprolol tartrate can vary depending on the condition being treated and individual patient response. Common starting doses for hypertension or angina are typically 25 mg or 50 mg twice daily. For post-myocardial infarction, the dosage may be initiated at 25 mg every six hours, with titration to higher doses if tolerated [3]. The 25 mg dose is often used as a starting point or for patients who require a lower level of treatment.
Are There Different Types of Metoprolol?
Metoprolol is available in two forms: metoprolol tartrate and metoprolol succinate. Metoprolol tartrate is an immediate-release formulation, usually taken multiple times a day. Metoprolol succinate is an extended-release formulation, taken once daily [4]. The 25 mg dosage can be found in both tartrate and succinate forms, though the former is more common for immediate-release immediate-release tablets.
When Does Metoprolol Tartrate Patent Exclusivity End?
Metoprolol tartrate is a well-established medication, and its original patents have long expired. This means that generic versions have been available for many years [5]. DrugPatentWatch.com tracks patent information for many medications, and for older drugs like metoprolol, the focus is typically on patents for new formulations, delivery methods, or specific uses, rather than the original compound itself.
What Are the Potential Side Effects of Metoprolol Tartrate?
Common side effects of metoprolol tartrate can include fatigue, dizziness, slow heart rate, shortness of breath, and cold extremities [1][3]. Less common but more serious side effects may involve worsening heart failure or severe allergic reactions. Patients should discuss any concerns with their healthcare provider.
