Dobutamine: beta 1> beta 2 > alpha 1
Milrinone

Strong vasoconstriction & Strong Inotropic:
NorEpi: Alpha 1, beta 1, alpha 2  
Dopamine: alpha 1, beta 1, dopaminergic

Strong vasoconstrictions:
Phenylpherine: alpha 1, alpha 2
Vasopressin: V1, V2

Strong everything:
Epinephrine (anaphylaxis shock): alpha 1, alpha 2, beta 1, beta 2
