Study Summary

This trial will help determine if a blood pressure medication can improve symptoms in people with POTS, a condition characterized by a high heart rate and disabling symptoms during standing.

Who is the study for?
This trial is for young women with POTS, a condition causing rapid heartbeat when standing. Participants must have had symptoms for at least 6 months, experience a heart rate increase of ≥30 bpm within 10 minutes of standing without significant blood pressure drops, and be in the early phase of their menstrual cycle. They should not be overweight or suffering from conditions like heart disease, high blood pressure, diabetes, or taking certain medications.Check my eligibility
What is being tested?
The study tests Moxonidine's effect on POTS symptoms compared to a placebo. Moxonidine is a blood pressure medication that reduces sympathetic nerve activity which might help lower heart rate and improve standing tolerance in patients with high resting sympathetic activity.See study design
What are the potential side effects?
Moxonidine may cause side effects such as dry mouth, fatigue, headache, dizziness upon standing (due to lowered blood pressure), sleep disturbances and skin reactions. The severity can vary among individuals.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Placebo then MoxonidineExperimental Treatment2 Interventions
After screening/baseline evaluations, patients will be discharged home on placebo identical to moxonidine once daily PO. After two weeks, the patients will be re-admitted for study testing while on placebo. At completion of this testing, patients will start taking moxonidine 0.2-0.4 mg/day PO to be continued at home. After two weeks, the patients will be re-admitted for study testing while on moxonidine.
Group II: Moxonidine then PlaceboExperimental Treatment2 Interventions
After screening/baseline evaluations, patients will be discharged home on moxonidine 0.2-0.4 mg/day PO. After two weeks, the patients will be re-admitted for study testing while on moxonidine. At completion of this testing, patients will start taking matching placebo once daily PO to be continued at home. After two, the patients will be re-admitted for study testing while on placebo.
