Beta 2 location
Smooth muscle
Alpha adrenergic responses
Vasoconstriction & CNS stimulation
Beta adrenergic responses
Bronchial, GI, and uterine smooth muscle relaxation, glycogenolysis, cardiac stimulation
Dopaminergic response
Renal vessel dilation, causing increase blood flow here
Direct-acting sympathomimetics
Binds directly to the receptor and causes a physiologic response
Indirect-acting sympathomimetic
Causes release of catecholamine that the binds to the receptor and causes the physiologic response
Mixed-acting sympathomimetic
Directly stimulates receptor by binding to it & indirectly stimulates by causing release of catecholamine to bind to the receptor
Alpha adrenergic drug effect
Vasoconstriction of the blood vessels (causes an increase in blood pressure)
Positive inotropic effect
Increased force of contraction
Positive chronotropic effect
Increased heart rate
Positive dromotropic effect
Increased conduction through the AV node
Beta adrenergic drug effect
Bronchodilation
