What is the effect of adrenaline on blood pressure and heart rate?

What drugs can i use to characterise these effects?What is the effect of adrenaline on blood pressure and heart rate?
Adrenaline acts directly on the heart to increase the heart rate.
It also act on the blood vessels, cause vasoconstriction, and increasing blood pressure.
Epinephrine IS adrenaline, and exerts these effects.
Neosynephrine (yes, the nose spray) will rationale vasoconstriction (that's how the nose spray works) and increase blood pressure. (We use it IV contained by the OR)
Caffeine will simulate the effects of adrenaline.
(Atropine is vagolytic, and causes heart rate to walk up by a different mechanism)
Hope that helps.
Systolic BP increases, and heart rate increases substantially.
If you want to mimic these effects, you'd want some epinephrine. (drug label for adrenaline)
Another good bet would be atropine.
*** There are no endorsed, non-prescription drugs that you can use for this. Sorry!
Increase heart rate and blood pressure.
