WebEphedrine is given as an intravenous bolus of 5 to 10 mg. It is effective in the same dose range when administered intramuscularly, albeit with slower onset and longer duration. When given in repeated doses, tachyphylaxis occurs, probably because of depleted norepinephrine stores. Ephedrine causes an increase in systolic, diastolic, and MAPs.

They affect the muscles in the walls of the arteries and veins, preventing the muscles from tightening and the walls from narrowing. As a result, blood flows more easily through the vessels. The heart doesn't have to pump as hard, reducing blood pressure.
