Pattern of out-patient drug treatment of hypertension in Korle-Bu Teaching Hospital, Accra.
In a retrospective study of the pattern of drugs used in the initial treatment of hypertension, 300 case notes of hypertensive patients attending medical clinics at the Korle-Bu Teaching Hospital, Accra and whose treatment were initiated during the period 1973-1993, were reviewed. The mean age of patients was 55 years, mean pre-treatment systolic and diastolic pressures were 179.5 +/- 25. 5 and 108.5 +/- 14.2 mm Hg, respectively, with 85% of patients being female. The frequencies of individual drugs prescribed for the initial treatment of hypertension were: diuretics (90%), reserpine (46%), methyldopa (31%), and propranolol (30%). Single drug treatment was prescribed for 18%, two drugs for 60% and three or more (multiple drugs) for 22% of patients. The mean number of drugs per patient was 2.2 Patients prescribed multiple drugs had pre-treatment systolic and diastolic blood pressures which were significantly (p < 0.01) higher than those prescribed 2 drugs which were, in turn, higher (p < 0.001) than those prescribed single drugs. The results showed that during the period 1973-1993, diuretic based "stepped care" therapy was the main first line anti-hypertensive drug management regime. "Old" anti-hypertensive drugs were more commonly used than newer ones. The cost and availability drugs and the pretreatment blood pressure were probably the main determinants of the choice of the type and number of drugs prescribed.
