[24-hour effect and tolerance for perindopril (Prestarium) in mild and moderate essential hypertension].

A multicentre investigation of antihypertensive treatment by perindopril was conducted in three centres of Czechoslovakia. The investigation comprised 51 patients with mild to moderate essential hypertension (diastolic pressure 95-115 mmHg) who were taking perindopril for a period of three months, the initial dose being 4 mg (1 tablet per day). If the blood pressure did not drop to normal levels (dBP < 90 mmHg), the dose was increased to 8 mg after 1 month and if after 2 months of treatment the blood pressure did not reach normal levels, a thiazide diuretic was added. The antihypertensive effectiveness was assessed 24 hours after ingestion of the drug. The blood pressure declined significantly already after the first month of monotherapy with perindopril. It declined then significantly up to the end of the 3rd month of treatment. The systolic blood pressure declined by 9.4 mmHg after the first month of monotherapy with perindopril and by 15.9 mmHg after 3 months of treatment. The diastolic blood pressure declined by 8.1 mmHg after one month of monotherapy and by 12.4 mmHg at the end of three-month treatment. The clinical and biological tolerance was excellent and only one patient discontinued treatment for reasons not related to the administered drug. Twenty-four hour monitoring of the blood pressure also proved the favourable effect of perindopril.
