Two drugs better than one for kids with high blood pressure in lungs?

NCT ID NCT04039464

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This completed phase 3 trial tested whether giving children with pulmonary hypertension two drugs (sildenafil and bosentan) from the start works better than just one drug (sildenafil alone). The study enrolled 28 children who had not yet received long-term treatment. Researchers measured how well the children could do daily activities after 12 months and tracked any worsening of their condition. The goal is to find the best way to control this serious lung disease in kids.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Sildenafil (Revatio) and Bosentan (Tracleer)

What this could lead to

If it works, this could show that starting with two drugs early is better than one for controlling pediatric pulmonary hypertension and improving daily life.

What could go wrong

This is a small, completed trial with only 28 children, so results may not apply to all kids. The drugs can have side effects like liver problems or low blood pressure.
