Epinephrine Hydrochloride Injection

It has both α-receptor and β-receptor stimulating effects. Alpha-receptor stimulating causes vasoconstriction of the skin, mucous membranes, and visceral vessels. β-receptor stimulating causes coronary vasodilation, skeletal muscle, myocardial excitation, increased heart rate, and relaxation of bronchial smooth muscle and gastrointestinal smooth muscle. The effect on blood pressure is dose-related. Common doses increase systolic blood pressure while diastolic blood pressure does not increase or decreases slightly. High doses increase both systolic and diastolic blood pressure.
