RESUMO
INTRODUCTION: Hypertension has been reported as the strongest modifiable risk factor for cardiovascular morbidity and mortality. AIMS: The aim of the study was to identify the most prescribed antihypertensive drugs, its patterns, comorbidities, cost of medications, and laboratory investigations. SETTINGS AND DESIGN: This study was a cross-sectional, descriptive study of hypertensive patients conducted at the Lagos State University Teaching Hospital, Ikeja. SUBJECTS AND METHODS: A total of 200 case notes were retrieved from the medical records unit over a period of 8 weeks. Information on antihypertensive prescriptions and comorbidities was retrieved. The average cost of medications and laboratory investigations was calculated. Statistical Analysis Tool Used: SPSS software version 16. RESULTS: The mean age of the patients was 58.44 ± 12.65 years. Of the 200 patients, 5 (2.5%) were on monotherapy and 195 (97.5%) were on combination therapy. One hundred and twenty (60%) patients had comorbidities which included congestive heart failure 55 (27.5%), diabetes mellitus 22 (11%), hyperlipidemia 15 (7.5%), and cardiovascular disease 13 (6.5%). The various classes of antihypertensive drugs prescribed were diuretics 128 (64.0%), beta-blockers 126 (63.0%), calcium channel blockers 106 (53.0%), angiotensin-converting enzymes inhibitors 103 (51.5%), angiotensin receptor blockers 33 (16.5%), alpha blockers 9 (4.5%), and fixed drug combinations 2 (1.0%). The average cost per month of the antihypertensive medications was ⦠2045 (US$10.2). CONCLUSIONS: Antihypertensive prescription pattern was in accordance with the seventh report of Joint National Committee on Prevention, Detection, Evaluation, and Treatment of high blood pressure. Community-based insurance scheme should be encouraged and effective implementation of integrated noncommunicable diseases screening into the primary health care services would be helpful.
