What are Metoprolol tartrate tablets 20 mg for essential hypertension, angina pectoris, tachyarrhythmia (Lopressor, Seloken, Metolar)?

Metoprolol tartrate is an immediate-release form of metoprolol, a selective antagonist of b1 receptor. It reduces the pulse rate, regulates irregular pulses and lowers blood pressure. Unlike succinate forms of metoprolol, which have a longer release, Metoprolol tartrate tablets prevent angina attacks by rapidly suppressing excess heart activity. Also, this medicine prevents myocardial damage and headaches.

Metoprolol tartrate tablets are effective for the treatment of essential hypertension, angina pedis, and tachyarrhythmia. Researchers proved that an active principle provides a significant effect on quality of life of patients, ejection percentage, exercise capacity, and reduces the risk of need of heart transplantation. Currently, some studies are also showing that metoprolol can be used to treat social anxiety and performance anxiety by suppressing stress-related reactions like sweating, dizziness and rapid heart beat.
