RAISE BP Trial Summary

This trial tests if a drug can improve BP, syncope, QOL, chest pain, and OAB in POTS patients, funded by the American Heart Association.

Who is the study for?
This trial is for adults over 18 with Postural Orthostatic Tachycardia Syndrome (POTS) who often feel faint or have rapid heartbeats due to low blood pressure and haven't found relief with standard treatments. It's not for those allergic to Mirabegron, pregnant, breastfeeding, with severe kidney issues, certain heart conditions, recent stroke or heart attack, active thyroid problems, or taking specific drugs.Check my eligibility
What is being tested?
The study tests if Mirabegron can help raise blood pressure and improve life quality in POTS patients by preventing fainting spells and reducing chest pain and bladder symptoms. Two doses of Mirabegron (25 MG & 50 MG) are being compared to find the most effective one.See study design
What are the potential side effects?
Mirabegron may cause increased blood pressure, urinary tract infections (UTI), headaches, dizziness, nausea, diarrhea constipation or joint pain. Some people might also experience a fast heartbeat.
