Comparison of the Effects of Piroxicam and Diclofenac Sodium as Treatments for Primary Dysmenorrhea.

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.

Project description:IntroductionThe most frequently prescribed analgesic drugs in primary care centers in Turkey are diclofenac and paracetamol, respectively. In this study, we aimed to compare paracetamol-included prescriptions (PIP) and diclofenac-included prescriptions (DIP) generated for adult patients in primary care.MethodsIn this cross-sectional study, PIPs (n = 280 488) and DIPs (n = 337 935) created for adults by systematic sampling among primary care physicians working in Istanbul in 2016 (n = 1431) were examined. The demographic characteristics, diagnoses, and additional drugs in PIPs and DIPs were compared.ResultsWomen constituted the majority in both groups (69.8% and 67.9%, respectively; P < 0.05), and mean age at PIP (52.6 ± 18.8 years) was lower compared to DIP (56.3 ± 16.1 years), (P < 0.05). In single-diagnosis prescriptions, 11 of the 15 most common diagnoses in PIP were respiratory tract infections (47.9%); three pain-related diagnoses formed 4.6% of all these prescriptions. In DIP, the number of pain-related diagnoses, mostly of musculoskeletal origin, was eight (28.5%); four diagnoses (7.8%) were upper respiratory tract infections. While hypertension was the third most common diagnosis in PIP (6.1%), it was ranked first in DIP (8.0%). The percentage of prescriptions with additional analgesic (14.0% versus 18.3%, P < 0.001), proton-pump inhibitor (13.8% versus 18.4%; P < 0.001), and antihypertensive (22.0% versus 24.8%, P < 0.001) was lower in PIP compared to DIP. However, the percentage of prescriptions with antibiotics (31.3% versus 14.7%, P < 0.001) was higher in PIP.ConclusionParacetamol appears to be preferred mostly in upper respiratory tract infections compared to the preference of diclofenac rather in painful/inflammatory musculoskeletal conditions. The presence of hypertension among the most commonly encountered diagnoses for these analgesic drugs points to challenges in establishing the diagnosing-treatment match and indicates potential irrational prescribing practice, especially for interactions.

Project description:Primary dysmenorrhea (PD) is a common gynecological disorder. Hitherto, animal models which recapitulate clinical features of PD have not been fully established. We aimed to examine whether a pain model in mice could mimic the clinic features of PD. After pretreated with estradiol benzoate (1 mg/kg/day) intraperitoneally (i.p.) for 3 consecutive days, non-pregnant female Imprinting Control Region mice (6-8 weeks old) was injected with 0.4 U of oxytocin to induce the stretching or writhing response which was recorded for a time period of 30 min. During the writhing period, the uterine artery blood flow alterations were examined by Doppler ultrasound detection. After writhing test, the uterine morphological changes were observed by hematoxylin and eosin (H&E) staining histopathology. In addition, enzyme-linked immunosorbent assay kit was used to measure the levels of prostaglandins F2?/prostaglandins E2 (PGF2?/PGE2) and TXB2 (a metabolite of TXA2)/6-keto-PGF1? (a metabolite of PGI2) in the uterine tissue homogenates and plasma, respectively. Western blot analyses were performed to determine the expressions of oxytocin receptor (OTR), beta2-adrenergic receptor (beta2-AR), and cyclooxygenase-2 (COX-2) in uterine, which are responsible for the uterine contraction. The writhing response only occurred in the estrogen pretreated female mice. The area of uterine myometrium significantly decreased along with the increased thickness in the oxytocin-induced estrogen pretreated mice model. The uterine artery blood flow velocity dropped, while the pulsatility index and resistance index slightly increased after the injection of oxytocin. The PGF2?/PGE2 level significantly increased and the plasma TXB2/6-keto-PGF1? level significantly enhanced. Compared with the control group, the uterine histopathology demonstrated moderate to severe edema of endometrium lamina propria. In consistent with the uterine morphological changes, a significant reduction of beta2-AR and a significant increase of OTR and COX-2 in the uterine tissue were observed. The writhing response was caused by the abnormal contraction of uterus. The uterine spasm and ischemia changes of oxytocin-induced estrogen pretreated female mice model were similar to the pathology of human PD. We reported an in vivo mice model, which can be used to study PD and for clinical therapeutic evaluations.
