What this trial studies

This double-blind, randomized trial enrolls women aged 18–35 presenting to the emergency department with primary dysmenorrhea and a VAS pain score of ≥6. Participants are assigned to receive either two ampoules of IV magnesium sulfate or IV dexketoprofen, each diluted in 100 mL saline and given over 15 minutes. Pain is measured on a Visual Analog Scale before treatment and one hour after administration, with secondary outcomes including patient satisfaction, vital sign changes, and adverse effects. The trial compares the short-term analgesic effectiveness and safety profile of IV magnesium versus a standard NSAID for acute dysmenorrhea.

Who should consider this trial

Good fit: Women aged 18–35 with primary dysmenorrhea, regular menstrual cycles, a VAS pain score ≥6 at presentation, not pregnant or breastfeeding, and willing to provide informed consent at the enrolling emergency department.

Not a fit: Patients with secondary dysmenorrhea or underlying gynecologic pathology, pregnancy or breastfeeding, recent use of analgesics/muscle relaxants, renal failure, cardiac arrhythmia, or known allergy to the study drugs are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, IV magnesium could provide a rapid alternative to NSAIDs for emergency relief of severe menstrual cramps, potentially reducing NSAID exposure.

How similar studies have performed: Some small studies and observational data suggest magnesium can reduce menstrual and musculoskeletal pain, but randomized head-to-head comparisons with NSAIDs are limited, so this specific comparison is relatively novel.
