Sardopa 500 Tablet

Adults-Initiation of Therapy: The Usual Starting Dosage of Methyldopa is 250 mg Two or Three Times a Day in the First 48 Hours. The Daily Dosage then may be Increased or Decreased, Preferably at Intervals of not Less Than Two Days, Until an Adequate Response is Achieved. To Minimize the Sedation, Start Dosage Increases in the Evening. When Methyldopa is Given to Patients on other Antihypertensives, the Dose of these Agents may Need to be Adjusted to Dffect a Smooth Transition. When Methyldopa is Given with Antihypertensives Other than Thiazides, the Initial dosage of Methyldopa should be Limited to 500 mg Daily in Divided Doses; when Methyldopa is Added to a Thiazide, the Dosage of Thiazide Need not to be Changed.
Maintenance Therapy: The Usual Daily Dosage of Methyldopa is 500 mg to 2 g in Two to Four Doses. Although Occasional Patients have Responded to Higher Doses, the Maximum Recommended Daily Dosage is 3 gm. Occasionally Tolerance may Occur, usually Between the Second and Third Month of Therapy. Adding a Diuretic or Increasing the Dosage of Methyldopa Frequently will Restore Effective control of Blood Pressure. A Thiazide may be Added at Any Time During Methyldopa Therapy and is Recommended if Therapy’has not been Started with a Thiazide or if Effective Control of Blood Pressure cannot be Maintained on 2 gm of Methyldopa Daily. Methyldopa is Largely Excreted by the Kidney and Patients with Impaired Renal Function may Respond to Smaller Doses. Syncope in Older Patients may be Related to an Increased Sensitivity and Advanced Arteriosclerotic Vascular Disease. This may be Avoided by Lower Doses.
Pediatric Use: Initial Dosage is Based on 10 mg/kg of Body Weight Daily in Two to Four Doses. The Daily Dosage then is Increased or Decreased until an Adequate Response is Achieved. The Maximum Dosage is 65 mg/kg or 3 gm Daily, whichever is Less.
