Summary

This study tests two common pain relievers—tramadol and paracetamol—against a placebo (salt water) to see which works best for managing pain during active labor in first-time mothers. About 300 women will take part, and researchers will measure how long labor lasts, any side effects, and the health of both mother and baby. The goal is to find a safe and effective option to ease labor pain.
