|
|
Alpha 1 receptor |
Effects smooth muscles of blood vessels |
|
|
Alpha 2 receptors |
Inhibits norepinephrine causing sedation and analgesia |
|
|
Beta 1 |
In heart, increase HR, conduction and contractility |
|
|

|
|
Side effect of alpha 1 |
Constricts arterioles = increase BP |
|
|
Side effects of alpha 2 |
Initial hypertension followed by reflex bradycardia and finally lowered BP and cardiac output |
