Usual Adult Dose for Hypertension
Initial dose: 10 mg orally once a day alone or in combination with a diuretic
Maintenance dose: 20 to 40 mg orally once a day; some patients may have further response at 80 mg once a day
-Dosages should be adjusted according to blood pressure response at peak (2 to 6 hours post dose) and trough (about 24 hours after dosing) blood levels.
-Consider dividing the daily dose in patients where the trough response is inadequate.
-Stop the diuretic 2 to 3 days prior to beginning therapy with this drug; it may be resumed at a later time if clinically indicated.
-If stopping the diuretic is not possible, careful medical supervision is recommended for several hours until blood pressure has stabilized.

Target dose range: 20 to 40 mg orally once a day
Maximum dose: 40 mg orally once a day
-Patients should be observed under medical supervision for at least 2 hours following the initial dose until blood pressure stabilizes.
-Dosages should be increased over a several week period based on tolerability.
-The presence of hypotension, orthostasis, or azotemia early in dose titration should not preclude further careful dose titration; consider dose reducing concomitant diuretic.
