Aldomet

Pharmacology

This belongs to a group of medicines called alpha-adrenergic agonists.

Methyldopa is an aromatic-aminoacid decarboxylase inhibitor found in animals and in man. Although the mechanism of action has yet to be conclusively demonstrated, the antihypertensive effect of

Methyldopa probably is due to its metabolism to alpha-methylnorepinephrine, which then lowers arterial pressure by stimulation of central inhibitory alpha-adrenergic receptors, false neurotransmission, and/or reduction of plasma renin activity.

Methyldopa has been shown to cause a net reduction in the tissue concentration of serotonin, dopamine, norepinephrine, and epinephrine.

Indications

Aldomet is indicated for the treatment of hypertension or high blood pressure.

Children:

The doctor will work out the number of tablets to be taken, based on the weight of the child. The usual initial dose for children is 10 mg per kg of body-weight per day, taken in two to four doses.

The number of tablets may be increased or lowered at intervals. The maximum dosage is 65 mg/kg or 3 g daily, whichever is less.

The number of tablets to be taken will be on the label of your medicine. If you are unsure about the dose you should take, you must talk to your doctor or pharmacist.
