Prosan HZ 12.5/50 Tablet

Dosing must be Individualised. The Usual Starting Dose of Losartan is 50 mg Once Daily, with 25 mg Recommended for Patients with Intravascular Volume Depletion (e.g., Patients Treated with Diuretics) and Patients with a History of Hepatic Impairment. Losartan can be Administered Once or Twice Daily at Total Daily Doses of 25 to 100 mg. If the Antihypertensive
Effect Measured Trough Using Once a Day Dosing is Inadequate, a Twice a Day Regimen at the Same Total Daily Dose or an Increase in Dose may Give a More Satisfactory Response. Hydrochlorothiazide is Effective in Doses of 12.5 to 50 mg Once Daily and can be Given at Doses of 12.5 to 25 mg as Prosan HZ. To Minimise Dose Independent Side Effects, it is Usually Appropriate to Begin Combination Therapy Only After a Patient has Failed to Achieve the Desired Effect with Monotherapy.
