Effect of Oral Calcium Carbonate on Uterine Contractility and Labor Outcomes: A Randomized Controlled Trial

Arrowhead Regional Medical Center·interventional·Posted Jul 9, 2025·Updated Jul 9, 2025

In Brief

A Phase 3 clinical trial evaluating Calcium carbonate for Uterine Contraction and 6 related conditions. Completed, enrolled 89 participants across 1 site.

Detailed Summary

The goal of this clinical trial is to learn if oral calcium carbonate can improve uterine contractions and labor outcomes in term pregnancies. It will also evaluate the safety of calcium carbonate when used during labor. The main questions it aims to answer are: Does oral calcium carbonate increase uterine contraction strength? Does it lead to shorter labor duration or higher vaginal delivery rates? What side effects or complications, if any, occur with calcium carbonate use during labor? Researchers will compare oral calcium carbonate to no treatment to see if it helps improve labor efficiency and reduce cesarean delivery rates. Participants will: Be randomly assigned to receive either 2,000 mg of oral calcium carbonate or no intervention Undergo monitoring with an intrauterine pressure catheter to measure contraction strength Be observed for two hours without oxytocin to assess calcium's direct effect on contractions Have data collected on labor progression, delivery outcomes, and neonatal health
