Autonomic Nervous System Drugs Flashcards
A medications that inhibit sympathetic activity are known as sympatholytic or sympathoplegic drugs. They primarily function as adrenergic receptor antagonists. They prevent norepinephrine or epinephrine from binding to receptors, causing the effect to be “cut” or “take a blow,” as the ends “-lytic” and “-plegic” indicate.
Sympatholytic Drugs
A kind of neuron that sends impulses to the CNS.
Afferent
A kind of neuron that receives impulses, transmits through the spinal cord to effector organ cells
Efferent
The receptor organ cells: alpha, beta
Sympathetic
The receptor organ cells: nicotinic, muscarinic
Parasympathetic
It is a drugs that produces a response
Agonist
A drugs that blocks a response
Antagonist
The purpose of administering autonomic medications is not to cure an autonomic problem, but to rectify abnormalities of target organs via autonomic nerves.
Pharmacologic Effect
It stimulates the SNS sympathomimetic.
Adrenergic Agonist
It stimulates the PNS para-sympathomimetic.
Cholinergic Agonist
It inhibits the SNS sympatholytic.
Adrenergic Antagonist
It inhibits the PNS para-sympathomimetic.
Cholinergic Antagonist
It influences one type of receptor.
Selective
It influences all receptors.
Non-selective
It is famous for military use as nerve gases.
Indirect acting irreversible
