[Impact of stopping reimbursement of olmesartan for hypertensive patients in primary care].

AIMS OF STUDY: Since January 2017, olmesartan-based treatment are no longer reimbursed by French national health insurance. Indeed, enteropathy cases, potentially lethal, were described in relation to this medication. Objectives were to study the impact of stopping the reimbursement of olmesartan for hypertensive patients.

PATIENTS AND METHOD: A descriptive retrospective study was performed with data from two primary care facilities in French occidental Normandy. To evaluate the blood pressure control, different blood pressure measurements were considered during the year before (period 1) and the year after (period 2) potential stopping olmesartan. A medico-economic analysis was also realized.

RESULTS

From June 2015 to July 2017, 107 hypertensive patients treated by olmesartan were included. Among them, 47 patients (44%) had an antihypertensive monotherapy. olmesartan had been mainly switched by another sartan (75%, 80/107) including valsartan (59%, 47/80). Mean blood pressures during period 1 and period 2 were not statistically different. Moreover, 83% of patients were initially controlled with olmesartan and 81% after switching medication (P=0,86). The use of olmesartan generated an additional cost of 58% compared to the other drugs that replaced it during period 2.

CONCLUSIONS

Stopping olmesartan reimbursement didn't seem to have a significant impact on blood pressure control of hypertensive patients while its cost is significant. In addition to potential serious side effects, olmesartan has not shown any improvement in cardiovascular morbi-mortality.
