Not Medical Advice: Pill imprint M 18 has been identified as Metoprolol tartrate 25 mg.
Metoprolol is used alone or together with other drugs to treat high blood pressure (hypertension). It is also used to treat severe chest pain (angina) and lowers the risk of repeated heart attacks and is given to individuals who have already had a heart attack. In addition, metoprolol is used to treat patients with heart failure.
This drug is a beta-blocker and it works by affecting the response to nerve impulses in several parts of the body, like the heart. As an outcome, the heart beats slower and decreases the blood pressure. When the blood pressure is lowered, the amount of oxygen and blood is increased to the heart.
A clinical trial study shows potential benefits of administering beta-blocker medication to heart attack patients in the ambulance. Early treatment of heart attack patients with an inexpensive beta-blocker drug called metoprolol, while in transit to the hospital, can significantly reduce damage to the heart during a myocardial infarction, according to clinical trial study results published in the journal Circulation.
