Effectiveness

How Lopressor Affects PatientsMetoprolol is a drug used to treat heart rate and cardiac output issues. It works by slowing the electrical signals that control the heart and reducing the amount of blood the heart pumps out. The MAPHY trial showed that metoprolol reduced sudden cardiac death and heart attack when compared to diuretics. Another 1990 study found that taking metoprolol after a heart attack reduced the risk of death and repeat heart attack by 17%.
How Lopressor works in the bodyMetoprolol works by blocking certain receptors in the heart. This reduces the heart's rate and strength of contractions, without affecting other parts of the body.

When to interrupt dosage

The measure of Lopressor is contingent upon the diagnosed disorder, for example Hemodynamically Stable, Thyroid Crisis and Atrial Fibrillation. The magnitude of dosage is contingent on the technique of delivery (e.g. Tablet, coated or Tablet - Oral) featured in the table beneath.

Lopressor Toxicity & Overdose RiskThe lethal dose of metoprolol in rats has been found to be between 3090 and 4670 mg/kg. Overdosing on metoprolol may cause a slow heartbeat, low blood pressure, difficulty breathing, and heart failure. To treat an overdose, doctors recommend emptying the stomach and then providing treatment based on the symptoms. Metoprolol has not been linked to cancer, mutations, or fertility problems, although long-term use of high doses may cause minor lung tumors.
