NCT ID NCT05049616
First seen Nov 11, 2025 · Last updated Jun 23, 2026 · Updated 34 times
Summary
This pilot study tested two common blood pressure medications—a combination pill of hydrochlorothiazide and lisinopril versus extended-release nifedipine—in 70 new mothers with high blood pressure after delivery. The goal was to see which pill controls blood pressure better in the first week and a half after childbirth. Both drugs are already used in standard care, so this study aims to refine treatment choices rather than discover a new therapy.

What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Hydrochlorothiazide/Lisinopril (Zestoretic) and extended-release nifedipine
What this could lead to
If it works, this could point toward a better first-choice pill for managing high blood pressure after childbirth.
What could go wrong
This is a small pilot study with only 70 participants, so results may not apply to all women. Both drugs are already used in standard care, so no major breakthrough is expected.
