Sample Use Guides

In Vivo Use Guide
Sixteen normal subjects received an intravenous infusion of PD123319 (10 mcg/minute for 5 minutes) and placebo, separated by one week.
Route of Administration: Intravenous
In Vitro Use Guide
The addition of 10(-6)M PD122319 to human arteries twenty minutes before the stimulation of vasoconstriction by angiotensin II caused a small but significant inhibition of vasoconstriction by 20%. In other arteries, the addition of 10(-6)M PD122319 twenty minutes before the stimulation of vasoconstriction by angiotensin II significantly enhanced vasoconstriction, maximally by 60%.
