metoprolool

Metoprolol is a medication belonging to a class of drugs called beta-blockers. It is primarily used to treat high blood pressure, also known as hypertension, and angina pectoris, which is chest pain caused by reduced blood flow to the heart. It is also prescribed to improve survival after a heart attack and to manage heart rhythm disorders.

The mechanism of action for metoprolol involves blocking the effects of adrenaline and noradrenaline, hormones that can increase heart rate and blood pressure. By blocking these hormones, metoprolol causes the heart to beat more slowly and with less force, which in turn lowers blood pressure and reduces the workload on the heart.

Metoprolol is available in various formulations, including immediate-release and extended-release tablets, as well as an injectable form. The dosage and frequency of administration depend on the specific condition being treated and the individual patient's response. It is typically taken once or twice a day.

Common side effects of metoprolol can include fatigue, dizziness, slow heart rate, and shortness of breath. Less common side effects may involve depression, gastrointestinal disturbances, and skin reactions. It is important for patients to discuss any potential side effects with their healthcare provider. Metoprolol should be used with caution in individuals with certain pre-existing conditions, such as asthma or severe heart failure, and should not be stopped abruptly without medical supervision due to the risk of rebound hypertension or angina.
