Abstract
Summary
1) Nine human subjects were given phentolamine (Regitine®) infusions to observe the effect upon plasma FFA levels. 2) There was a consistent abrupt rise in venous FFA levels ranging from 100-500 μm/l without blood glucose changes. FFA values remained higher 1 hour after infusion. 3) The mechanism of this phentolamine effect on lipid metabolism is not known.
We thank Dr. William E. Wagner, Ciba Pharmaceutical Products, Inc., for generous supply of Regitine® used.
