Main Article Content
Abstract
Background: hypertension and arthritis are two co-morbid diseases that require pharmaceutical care (PC) services. Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used for treatment of arthritis.
Objectives: The study evaluated the knowledge of pharmacist on the use of NSAIDs in this set of patients and the PC services rendered to them.
Methods: structured tested questionnaires were distributed to pharmacists working in public hospitals and community pharmacies in Ibadan metropolis. The questionnaire elicited information on the demographics of respondents, identification of drug related problems and ways of resolving them, knowledge on pharmacotherapy of arthritis and hypertension. Data was analysed with descriptive analysis using statistical package for the social sciences (SPSS) version 16 for windows.
Results: a total of 165 questionnaires were distributed with 124 properly filled and returned giving a response rate of 75.2%. Majority (64.5%) were females, the mean year of graduation of the respondents was 9.12years and 50.8% practice as Community pharmacists. Common PC activities include; counseling (84.4%), monitoring of patients B.P (53.3%), blood glucose measurement (53.3%), monitoring patient's using available laboratory results (44.3%). Majority (85.5%) resolved side effects complaint from patients by reassuring the patients that side effect will subside as therapy continues while 77.4% took full medication history and 65.3% consulted physician for a change of medication. Majority (88.7%) agreed that they encountered prescriptions containing NSAIDs for arthritis in their practice. Good numbers of the respondents had no idea of what measure to take when a patient diagnosed of arthritis and hypertension was prescribed NSAIDs if the blood pressure was control or when it was uncontrolled. Few 16.9% and 8.9% indicated they monitored B.P of such patients with controlled or uncontrolled B.P, while more than half (55.6%) of the respondent indicated that COX2 inhibitor are safer in hypertension as compared to COX1 and that NSAIDs effects on hypertension is dose dependent. Most (77.4%) of them indicated that NASIDs can exacerbate hypertension while 55.6% indicated that NSAIDs can induce hypertension.
Conclusion: Respondents' knowledge of the pharmacotherapy with antihypertensives and NSAIDs use in patients with hypertension co-morbid arthritis need to be improved. Good and well established pharmacistphysician relationship, refresher courses and remuneration of pharmacist for the PC services will also improve services provided by the pharmacist.
