Brief Summary:
  • Currently, nonsteroidal antiinflammatory drugs are widely used by emergency physicians in Turkey for the treatment of patients with Primary Dysmenorrhea.
  • The objective of the study is compare intramuscular Diclofenac sodium and piroxicam's pain reduction dysmenorrhea in emergency department (ED) adults.
  • The investigators second aim was to compare recurrent dysmenorrhea pain within 24 hours after discharge.

Condition or disease Intervention/treatment Phase
Primary Dysmenorrhea Drug: Piroxicam Drug: Diclofenac Sodium Phase 4

Detailed Description:
  • this is the randomized double blinded clinical trial to compare the efficacy of these two drugs in this clinical setting.
  • A randomized clinical trial was conducted in the ED of Pamukkale University Medical Faculty Hospital
  • Study personnel (emergency physicians and nurses) were trained before the study.
  • When intramuscular drugs (Piroxicam, Diclofenac sodium) was being recommended, an eligibility checklist was completed by the attending physician.
  • If there were no exclusion criteria, written informed consent was obtained and baseline information, including initial Dysmenorrhea pain severity ratings with VAS were recorded.
  • The need for identification and enrollment of participants by staff with conflicting work pressures resulted in recruitment of a convenience sample of patients.
  • All patients eligible for the study were randomized to one of two groups:
  • First Group: 20 mg of piroxicam (feldene ampoule -Pfizer-France) intramuscularly (IM) was given 200 patients,
  • Second Group: Diclofenac sodium 75mg (Miyadren drug-ampoule -Yavuz Istanbul) intramuscularly (IM) was given 200 patients which determined to be applied as a group.
  • Drug packs prepared in 5 ml syringes were numbered by an independent nurse, who not involved in the study.
  • Drugs were prepared according to the computer-generated random number sequence to assign treatment allocations
  • The allocation list was kept by the emergency nurse. Patients received the piroxicam, diclofenac sodium medication schemes according to their random allocations.
  • After enrollment and recording of baseline information, the next numbered study drug pack was obtained, and administered as a intramuscular.
  • Randomization was achieved by using computer software to generate random numbers. During the intervention, participants were monitored by an oxygen saturation (SpO2) monitor, an automatic sphygmomanometer (blood pressure), and a rhythm monitor (heart rate and rhythms)
  • One researcher blinded to patient allocation observed the whole procedure and recorded the Dysmenorrhea pain scores.
  • Patients in both groups received two types of medication in a similar manner, thus ensuring double blinding.
  • Dysmenorrhea pain scores were recorded at 0, 15, 30, 45 and 60 min on a VAS of 1 to 10
  • Rescue medication (100 mg of tramadol hydrochloride) was given intramuscular to patients if pain VAS scores ≥ 5 in forty five minutes after study drug administration.
  • All other medications required during the study also were recorded.
  • During the study, pulse rate, systolic blood pressure, diastolic blood pressure, respiration rate and oxygen saturation (SpO2) were recorded at baseline (0 min), 15, 30, and 60 min.
