Abstract

Abstract

Hypertension is the commonest non-communicable disease in Nigeria with a prevalence of about 20-25 per cent in adult Nigerians. This research work examined generic drug substitution and its impact on drug adherence among hypertensive patients attending the Consultant Out-Patient Department of Sobi Specialist Hospital, Ilorin, Nigeria. Self-report adherence, personal interview, structured questionnaires and patients’ prescriptions were used to determine drug adherence and treatment outcomes of 167 hypertensive patients on antihypertensive drugs. Adults between the ages of 40 and 80 years were mostly affected, and women were more vulnerable to the disease. The clinical signs and symptoms mostly reported by the patients include severe headache, chest pain, numbness of extremities and general body weakness. The widely utilized generic antihypertensive agents in the studied hospital include Amlodipine, Methyldopa, Nifedipine, Lisinopril among others and constituted 91.6% of all the prescriptions. The high rate of generic drug prescriptions in this hospital coupled with the consistent drug counselling offered to the patients by the pharmacist has greatly improved adherence rate to 67.7%. Generic drug substitution should be encouraged in all tiers of healthcare system to improve drug adherence and stem the tide of hypertension in this society. Also, public enlightenment and education should be strengthened to increase population awareness on the symptoms, risk factors, lifestyle modifications and complications of this silent killer disease.

Keywords: Hypertension, drug adherence, generic, prescriptions, substitution, Nigeria.
