Study Groups

Methacetin (for BT) before / after Propanolol treatment.
The methacetin breath test (MBT) will be performed before and after (within 2 hours) injection of Propanolol (BB) dose and once again after 60 days of oral administration of Propanolol.
Methacetin (with Breath testing device)
The methacetin is enriched with carbon 13, a stable non- radioactive isotope, and has been found to be safe in hundreds of studies. The material is very similar to acetominophen. 75 milligrams (mm) of this material pre- dissolved in water are used. This material undergoes rapid metabolism by the liver.
