Examples of sympathomimetic effects include increases in heart rate, force of cardiac contraction, and blood pressure. [1] The primary endogenous agonists of the sympathetic nervous system are the catecholamines (i.e., epinephrine [adrenaline], norepinephrine [noradrenaline], and dopamine ), which function as both neurotransmitters and hormones .
However, the serotonin receptor antagonism has side effects such as weight gain and impaired movement. [11] Hence, alpha-2 blockers are not used clinically due to its extensive binding. Similar to the alpha-1 blocker, the alpha-2 family will also present the first-dose effect , but it is generally less pronounced compared with the alpha-1 blockers.
They are given by injection. [2] Common side effects may include joint pain, rash, vomiting, and headache. [4] Serious side effects may include heart attacks, stroke, increased cancer growth, or pure red cell aplasia. [2] It is unclear if use is safe during pregnancy.
