Treatment of Senile Hypertension The Fosinopril in Old Patients Study (FOPS)

Data regarding the tolerance of ACE inhibitors in old age are sparse, despite this class of compound being regarded as one of the first-line agents for the treatment of hypertension. In the present trial, the efficacy and tolerance of the ACE inhibitor fosinopril was examined over a period of 12 weeks in an open trial of hypertensive patients aged over 60 years with diastolic hypertension (diastolic blood pressure 95 to 110 mm Hg) and isolated systolic hypertension (ISH; systolic blood pressure 160 to 219 mm Hg, diastolic blood pressure 80 to 94 mm Hg). Fosinopril decreased blood pressure from 174/101 mm Hg to 149/88 mm Hg in patients with diastolic hypertension and from 182/86 mm Hg to 151/80 mm Hg in patients with ISH. Seventy percent of patients did not require any adaptation of the initial fosinopril dose to achieve an adequate therapeutic response. In the patients in whom 20 mg fosinopril did not adequately reduce blood pressure, the addition of 12.5 mg hydrochlorothiazide was found to be slightly more effective than doubling the initial dose of the ACE inhibitor. Fosinopril was well tolerated and the occurrence of drug-dependent side effects was not increased in patients with renal insufficiency. Fosinopril is an excellent therapy for the treatment of hypertension in elderly patients, particularly because, as a consequence of its dual, compensatory excretion, no adaptation of the dose is necessary, even in patients with a physiological reduction in renal function.
