SUMMARYAn open, non‐comparative study of 10 weeks' duration was conducted in general practice to assess the safety of amlodipine in patients with mild to moderate hypertension. Of the 5352 patients entering the study, 5135 received amlodipine; 4621 patients (90%) with a mean age of 58.2 years completed the study. Normalisation of blood pressure was achieved in over 80% of patients with a mean reduction of 21/15 mmHg. The mean final dose of amlodipine was 6.8 mg/day. Adverse experiences possibly related to amlodipine were reported by 19.3% of patients, and overall adverse events led to withdrawal in 6.7% of patients. The most common reported side‐effect was oedema. The frequency of headache was almost identical in older and younger patients and oedema, flushing and dizziness were seen only slightly more often in elderly patients. Ninety per cent of patients were considered by their GP to have shown excellent or good toleration of therapy. Over 85% of patients elected to continue on amlodipine therapy after completion of the study.
