A member asked:
Why does codeine cause vasodilation in the body but vasoconstriction in the lungs?
A doctor has provided 1 answer
Doubtful: While vasodilitation has been reported I could not find evidence for vasoconstriction in lungs. exact mechanism is not clear. Personally I have not found any significant drop in BP in scores of patients taking codeine.
