Obesity study: Amlodipine vs Moxonidine
Official title Sympathetic Mechanisms in Obesity-Crossover Design
ClinicalTrials.gov ID: NCT05312892
What this study is testing
What is Amlodipine?
an investigational use of an approved antihypertensive medicine being studied as a potential treatment for obesity is designed to block calcium channels in blood vessel walls, causing vasodilation and lowering blood pressure
Also referred to as Norvasc.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see whether a short course of sympathetic blockade affects the body’s own glucose production.
- Who it's for
- Adults who are obese and have hypertension.
- What's involved
- Participants will take either a placebo, a blood‑pressure medicine (amlodipine), or a sympathetic‑blocking drug (moxonidine) for two weeks, then attend three clinic visits for blood tests. Neither they nor the analyst will know which treatment was given each time.
- Time commitment
- Two weeks of taking the study medication and three separate clinic visits for testing.
- Phase 2: a mid-size study of how well it works
- You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance. You may not know which one you got.
