Can a breastfeeding drug mend broken hearts after childbirth?
NCT ID NCT05180773
First seen Jun 26, 2026 · Last updated Aug 11, 2026 · Updated 2 times
Summary
This study tests whether bromocriptine, a drug that stops breastfeeding, can improve heart function in women newly diagnosed with peripartum cardiomyopathy (a type of heart failure after childbirth). 200 women will receive either bromocriptine or a placebo, plus standard heart failure care, for 8 weeks. Another 50 women who want to breastfeed will be observed without the drug. The main goal is to see if heart pumping ability improves at 6 months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Bromocriptine (a drug that blocks prolactin, often used to stop breastfeeding)
- What this could lead to
- If it works, this could offer a new treatment to help women with peripartum cardiomyopathy recover heart function and avoid heart failure, transplant, or a heart pump.
- What could go wrong
- This is a phase 4 trial, but the drug is already approved for other uses. It may not improve heart recovery, and it stops breastfeeding, which limits its use. Anticoagulation is needed to reduce clot risk.
