Summary

This trial aims to understand how minocycline affects blood pressure in people with treatment-resistant hypertension. It will investigate the extent to which minocycline lowers blood pressure and whether this effect varies among

Who is the study for?
This trial is for individuals with high blood pressure that doesn't get better with treatment. Participants will be studied to see how minocycline affects their condition, considering factors like race and changes in gut health.
What is being tested?
The study tests if minocycline can lower blood pressure in resistant cases over a 3-month period, compared to a placebo. It also explores whether the effects are due to changes in gut bacteria, inflammation or other factors.
What are the potential side effects?
Minocycline may cause side effects such as dizziness, fatigue, gastrointestinal issues, skin reactions and possibly affect the balance of gut bacteria.
