What is the goal of Autonomic Drugs?
Its goal is not to treat an autonomic disorder, to correct disorders of target organs through autonomic nerves.
It stimulates adrenergic receptors

What is a Selective?
Selectivity is the degree to which a drug acts on a given site relative to other sites.
What is Non-Selective?
Drugs that evoke a variety of responses throughout the body have a nonspecific response Drugs may act at different receptors.
What are Adrenergic Agonists?
