Abstract:
To observe the antihypertensive effects of the angiotensin-converting enzyme inhibitor, enalapril, a daily average dosage of 20mg was administred to 38 patients with essential hypertension for 4 weeks. Changes in blood pressure and heart rate, and the frequencies of adverse reactions during the drug administration were constantly observed. At the end of the 4th week of administration the mean diastolic blood pressure decreased from 104+/-11.3 to 91+/-7.9mmHg(<0.001), and the mean systolic blood pressure from 165+/-16.8 to 142+/-10.6mmHg(P<0.001), An effective antihypertensive action of enalapril was observed in 31 out of 38 cases(82%), and normalization of diastolic blood pressure below 85mmHg was shown in 27 cases(71%). The most remarkable antihypertensive effects were shown at the end of first week, and the effect increased progressively until the end of 4th week of therapy. There were no significant changes in heart rate during the observation period. Adverse reactions occured in only 7 cases(18%). These reactions included headache, dizziness, fatigue, skin rash and facial flushing in the order of frequency. Almost all of these reaction were mild and transient, disappearing spontanously without discontinuation of the medication. In conclusion, enalapril seems to be a safe and effective primary antihypertensive drug for the treatment of essential hypertension.
