Methods A randomized, double blind study was carried out in 60 patients with stage 1 and 2 essential hypertension. Patients were randomly divided into two groups and given homemade amlodipine besylate tablets (amlodipine besylate tablets group)5mg,2 times/per day and import amlodipine besylate tablets (norvase group)5mg, once/per day, for 8 weeks, respectively. At the beginning and end of the treatment, patients’liver and renal functions were examined, and their blood pressure, heart rate and side-effects were recorded every two weeks. Results The average reduction in blood pressure readings for the two treatment groups were 83.6% and 85.2%, respectively. No significant differences were found between two groups (P>0.05). SBP and DBP decreased significantly on the second week following treatment, and reached their peaks on the fourth week following treatment, and this good effect lasted until the end of the study. No significant changes were found in HR, routine blood examination, liver and renal functions, as well as electrocardiography after treatment. Adverse reactions were slight. Conclusion Homemade amlodipine besylate tablets are safe and effective for the treatment of mild and moderate essential hypertension. There are slight adverse reactions and the price is lower. So it can be well tolerated by the patients and has now become the first line drug for hypertension.
