“In conclusion, … combination of yohimbine and atomoxetine had a synergistic effect on blood pressure and orthostatic tolerance in peripheral autonomic failure, which may be explained by an increased release of norepinephrine in peripheral sympathetic neurons by &agr;-2 antagonism combined with a reduced norepinephrine clearance by norepinephrine transporter blockade.”
“We hypothesized that increasing residual sympathetic outflow with the &agr;-2 antagonist yohimbine would potentiate the pressor effect of norepinephrine transporter blockade with atomoxetine and improve orthostatic tolerance in peripheral autonomic failure.”
