Case of 30
Moderate or severe arterial hypertension
Dosage ALDOMET 500 mg Coated Tablet Case of 30
- In adults : usually start with 250 mg of methyldopa 2 or 3 times daily for the first 48 hours.
Then, adjust the daily dosage by increasing, if necessary, in increments of 48 hours at least, until a satisfactory therapeutic result is obtained. The usual dosage is 750 mg to 1.5 g / day, without exceeding 3 g per day.
Methyldopa can be started in most patients already treated with other antihypertensives by discontinuing these drugs, in a progressive manner if necessary. When methyldopa takes over from another antihypertensive agent, its dosage should initially be limited to no more than 500 mg per day, then increased as needed, with each dose increase to be separated from the previous dose by less 2 days.
- In children : administer at the beginning 10 mg / kg of body weight and per day, in 2 to 4 doses.
Then, adjust the dosage-increase or reduce doses-to obtain a satisfactory result. The maximum dosage is 65 mg / kg, without exceeding a total dose of 3 g / day.
Many patients experience a sedative effect at least at the beginning of treatment or when increasing the doses of the drug. Consequently, it seems desirable that the increase of the doses relates first to the catch of the evening.
