Abstract

BACKGROUND: NSAIDs are the most common agents used in dysmenorrhea treatment. They reduce menstrual pain by reducing uterine pressure and PGF2alpha levels in the menstrual fluid. The aim of this study was to compare the effects of piroxicam and diclofenac sodium as treatments for primary dysmenorrhea.

MATERIAL AND METHODS: The study was conducted using a randomized and double-blind method. Patients with Visual Analogue Scale (VAS) scores greater than 5 were accepted into the study. The patients who were suitable for inclusion were randomized into 2 groups and received either intramuscular piroxicam or diclofenac sodium. The patients’ pain levels were measured at baseline and at 15, 30, 45, and 60 min. A VAS of 10 cm, a numeric scale, a verbal scale, and additional symptoms, as well as pain relapse after 24 hours and required analgesics, were recorded.

RESULTS: The study included 400 patients. Overall, 200 patients (50%) were in the proxicam group, and 200 patients were in the diclofenac sodium group. The average decrease on the VAS after piroxicam or diclofenac administration was measured as 7.9±1.8 cm and 7.9±1.7 cm (median ± standard deviation), respectively. The pain-reducing efficiency of all the treatments was compared using the Mann-Whitney U test (p=0.929). Rescue medication was needed for 25 patients in the proxicam group (p=0.014). Overall, 30 patients in the proxicam group and 41 patients in the proxicam group needed analgesics again in the 24-hour period after treatment (p=0.150).

CONCLUSIONS: At the end of our study, it was observed that there was no difference in the results of primary dysmenorrhea treatment with 20 mg piroxicam or 75 mg diclofenac sodium.
