LONG-TERM ACCEPTABILITY OF PERINDOPRIL - EUROPEAN MULTICENTER TRIAL ON 856 PATIENTS

The acceptability of perindopril in the long-term treatment of patients with mild to severe essential hypertension was assessed in a large European multicenter trial including 856 patients. Diastolic blood pressure (DBP) at inclusion was 95-125 mm Hg after 1 month of placebo. Normalization of blood pressure was defined as a DBP less-than-or-equal-to 90 mm Hg. Treatment was started with perindopril 4 mg once daily and increased when necessary to 8 mg daily. If DBP was not controlled, a second drug (hydrochlorothiazide) and finally a third drug were added. After 1 year of treatment in all 690 evaluable patients, supine systolic and diastolic blood pressure decreased by 29 mm Hg (from 172 +/- 1 to 143 +/- 1 mm Hg, p < 0.001) and 19 mm Hg (from 105 +/- 1 to 86 +/- 1 mm Hg, p < 0.001), respectively. Perindopril monotherapy normalized blood pressure in 55% of patients and total percentage of normalization was 78%. The overall incidence of withdrawals for side effects was 6.8%, the most common side effect being cough (2.2%). The most frequent complaints reported were cough (7.0%), headache (5.6%), asthenia (5.1%), mood and/or sleep disturbance (5.1%), and dizziness (3.2%). The small changes observed in hematologic and biochemical parameters were not clinically relevant.
