Could a bladder drug help POTS patients stop fainting?

This small pilot study tested whether mirabegron, a drug typically used for overactive bladder, can raise blood pressure and reduce fainting in people with POTS who have low blood pressure that standard treatments didn't help. Twenty adults took either 25 mg or 50 mg of the drug for 8 weeks. Researchers measured blood pressure changes and tracked fainting episodes, but technical issues limited the data available for analysis.
