POTS patients may get relief from blood pressure drug, early study hints
NCT ID NCT04050410
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase study tests whether a single dose of moxonidine, a blood pressure medication that lowers sympathetic nerve activity, can reduce symptoms like rapid heartbeat and lightheadedness in people with postural tachycardia syndrome (POTS). The trial enrolls 48 adults aged 18-55 who meet standard POTS criteria. Researchers will compare symptom changes after taking moxonidine versus a placebo pill to see if lowering sympathetic activity helps.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Moxonidine (a blood pressure medication)
What this could lead to
If successful, this study could point toward a more personalized treatment for POTS by identifying patients who benefit from lowering sympathetic activity.
What could go wrong
This is a very early, small pilot study with only 48 participants. It tests a single dose, so results may not reflect long-term effects or apply to all POTS patients.
