Pharmacists’ clinical interventions are an important aspect of pharmacy practice that improve blood pressure reduction and medication adherence. These unique clinical interventions address many barriers to hypertension treatment outcomes, such as blood pressure, and medication adherence. Pharmacists’ clinical interventions also directly improve patient’s and caregiver’s knowledge and understanding about the patient’s current medication therapy. The general aim of the study was to assess the impact of pharmacists’ clinical intervention on treatment outcomes among hypertensive patients. A multi-cluster, prospective, randomized intervention of 473 Nigerian hypertensive patients in which the impact of pharmacist’s clinical interventions was assessed and compared to the routine Standard Medication Dispensing (SMD) practices among adult hypertensive patients. Patients’ baseline and end of study blood pressure measurements and medication adherence scores were recorded from baseline to a three months’ follow-up visit. The data were collected by using a four-part questionnaire. The data collated were analyzed by descriptive statistics, and Independent t-test. Four hundred fourteen patients completed the study. The results showed that mean blood pressure reductions from baseline and endpoint was statistically significant in the Intervention group. Pharmacists’ clinical interventions when implemented have immense benefits of improving treatment outcomes among patients with hypertension. For any health care system to thrive in its management of hypertension, the involvement of pharmacists’ clinical interventions is strongly recommended.
