Abstract
Purpose : To estimate the incidence and features of adverse events resulting from the use of calcium channel blockers a multicenter postmarketing surveillance study was carried out. Method : To ascertain adverse events associated with calcium channel blockers usage, we followed regularly the hypertensive patients with the use of calcium channel blockers at the interval of 2,4,6,8 weeks. A total of 360 patients, 17,825 person-days, at 11 clinics were observed from February 1993 to September 1993. The incidence patterns of adverse events were analysed using Kaplan-Meier method. Results : Median follow-up days per person were 54 and the proportion of uncensored cases was 56.7%. Vasodilatory adverse events were observed in 38.9% of the patients during 8 weeks, where flushing, headache, palpitation, dizziness and peripheral edema occurred in 23.3%, 13.5%, 13.3% , 7.6% and 6.6% of the patients, respectively. These declined with time during continued therapy. The incidence of flushing and headache in younger patients(<50 years) were higher than those in older patients(>50 years). The incidence of flushing and peripheral edema associated with use of Niterndipine were higher than those associated with the use of Nicardipine and Amlodipine. The incidence of withdrawal due to adverse events was 10%. Apart from flushing headache, palpitation dizziness and peripheral edema, all other adverse events were constipation, indigestion nausea, gingival hyperplasia, facial edema and fatigue. Conclusion : Vasodilatory adverse events were observed in 38.9% of the patients with the use of calcium channel blockers, which declined with time during continued therapy. Incidences of flushing, headache and peripheral edema were associated with sex, age and the type of calcium channel blocker.
