Blood pressure drug may help preserve insulin in cystic fibrosis

NCT ID NCT07688070

First seen Jul 07, 2026 · Last updated Jul 10, 2026 · Updated 3 times

Summary

This study tests whether verapamil, a common blood pressure medication, can help protect insulin-producing cells in people with cystic fibrosis who have early blood sugar problems or diabetes. Participants take verapamil for several weeks, and researchers measure changes in insulin and C-peptide levels after a meal. The goal is to see if this drug can slow or improve glucose control in this population.

What this could lead to
If it works, this could point toward a new way to preserve insulin production and manage blood sugar in people with cystic fibrosis.
