The analysis of prescription frequency and the factors on adverse reactions of NSAIDs for post-operative pain in orthopedic patients

Recently, adverse reaction of non-steroidal anti-inflammatory drugs (NSAIDs) is the critical problem, although NSAIDs are one of the most commonly used classes of medications worldwide. Therefore, it is worthwhile to investigate the prescription frequency and the factors on adverse reactions of NSAIDs for post-operative pain in orthopedic patients of our hospital. In orthopedic field, loxoprofen was most prescribed in various kinds of NSAIDs. Logistic regression analysis strongly indicated that previous adverse reaction or allergy caused by drugs (not NSAIDs) or food is the important role in the adverse reaction of NSAIDs. In addition, significant correlation was observed between previous illness of gastrointestinal ulcer and gastrointestinal complication of NSAIDs. Moreover, the present study point out that pharmacist clinical intervention against the adverse reaction of NSAIDs may be saved on medical costs. Although further investigation may be needed, these present studies provide the good information for our medication management and instruction tasks (i.e. pharmaceutical care and counseling for inpatients) for post-operative pain of orthopedic patients.
