Overview
Metohexal 100mg Tablet contains metoprolol 100mg, a beta-1 selective (cardioselective) beta-blocker used to treat high blood pressure (hypertension), angina (chest pain from reduced blood flow to the heart), and certain heart rhythm problems, and to help manage stable chronic heart failure alongside other medicines.
Metoprolol selectively blocks beta-1 adrenergic receptors, found mainly in the heart, reducing the heart rate, the force of each heartbeat, and the release of renin (a hormone involved in blood pressure regulation). Together these effects lower blood pressure and reduce the heart’s oxygen demand.
How it Works
Metoprolol selectively blocks beta-1 adrenergic receptors, which are concentrated in heart tissue. By blocking these receptors, it slows the heart rate, reduces the force of contraction, and lowers renin release from the kidneys, which together decrease blood pressure and reduce the amount of oxygen the heart muscle needs to function.
Directions for Use
Take Metohexal 100mg Tablet with or immediately after food to help keep absorption consistent, at the same time(s) each day as your doctor has prescribed. Do not stop taking this medicine suddenly – abruptly stopping a beta-blocker can cause a rebound rise in blood pressure, worsening chest pain, or an abnormal heart rhythm; your doctor will reduce the dose gradually if it needs to be stopped.
Dosage
The usual starting dose of Metohexal 100mg Tablet for hypertension is around 50-100mg daily, which your doctor may adjust up to a maximum of about 200mg daily (often in divided doses) depending on your blood pressure or angina response. The exact dose for heart rhythm problems or heart failure is individualised by your doctor and usually started low with gradual adjustment.
