| Popis: | This trial was performed to determine the safe and effective dosage range of once daily diltiazem (diltiazem CD) capsules for treatment of essential hypertension. Patients with essential hypertension having supine diastolic blood pressure values greater than or equal to 95 mm Hg and less than or equal to 110 mm Hg were randomly assigned to receive placebo or one of four doses of diltiazem CD: 90, 180, 360, or 540 mg. Blood pressure was measured at trough, 24 hours after the dose, and at the time of peak effect, 10 hours after the dose. Diltiazem CD lowered both supine diastolic and systolic blood pressure. A linear dose response was seen with changes in diastolic and systolic blood pressure and heart rate for trough and peak measurements. Trough/peak ratios for the 180, 360, and 540 mg doses were all greater than 0.50. Adverse effects were dose related; those most commonly reported were headache (8.6%), bradycardia (8.1%), and edema (7%), with bradycardia and edema possibly dose related. It is therefore concluded that diltiazem CD is a safe and effective antihypertensive agent. |
