Table of contents:

Lopressor SR is a medication used to treat high blood pressure and prevent the symptoms of angina pectoris (chest pain). It contains the active ingredient metoprolol and belongs to the class of medications called beta-blockers. Beta-blockers work by blocking the effect of the hormone adrenaline, also known as epinephrine. This causes the heart to beat more slowly and with less force, which can help to lower blood pressure and reduce the workload on the heart.

Lopressor SR tablets are designed to be slowly but almost completely absorbed into the gastrointestinal tract. Additionally, Metoprolol Tartrate may also help to improve blood flow by reducing the constriction of blood vessels.

Use and Dosage

Metoprolol Tartrate SR comes in the form Sustained Release Tablet, which is typically taken by mouth once daily, with or without food. The extended-release tablets should be swallowed whole and should not be crushed, chewed, or split. Avoid abrupt discontinuation of the medication, as this can cause rebound hypertension and other adverse effects.

The recommended dosage for Metoprolol Tartrate SR varies depending on the individual and the condition being treated. However, the usual dosages for Metoprolol Tartrate IR can range from 100-450 mg per day for hypertension, depending on the individual's blood pressure and response to treatment. Any questions or concerns about dosages of Metoprolol Tartrate SR should be discussed with a healthcare professional.

Take exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
