Autonomic Nervous System drugs Flashcards
What is part of the peripheral nervous system that regulates and maintains homeostasis of involuntary functions in the body
Autonomic Nervous System
Drugs that produce a response
Agonist
Drugs that block a response
Antagonist
What are the 2 parts of the Nervous System?
Central and Peripheral System
Do alphas constrict or dilate
Constrict
Do betas constrict or dilate
Dilate
Two branches of ANS
sympathetic nervous system (SNS)
parasympathetic nervous system (PSNS)
It is a fight and flight response
SNS
What SNS receptor types respond to epinephrine or norepinephrine
alpha 1, beta 1, beta 2
What are PSNS receptor types?
Muscarinic
drugs that stimulate the sympathetic nervous system
Adrenergic drugs
agents that stimulate the parasympathetic nervous system in the same manner as acetylcholine
May also be called.. muscarinic agonist, parasympathomimetic, cholinomimetic
Cholinergic drugs
Drugs that block the action of acetylcholine and substances similar to acetylcholine at receptor sites in the synapse.
Cholinergic-blocking drugs
adrenergic drugs or also called …
sympathomimetics
Alpha2 Agonists: Methyldopa (Aldomet) USES
Uses: Lowers blood pressure
Main Uses of Cholinergic Drugs eyes
Decrease intraocular pressure in glaucoma, miosis
What are Beta-Adrenergic Adverse Effects?
CNS - tremors, headaches, nervousness, dizziness
Cardiovascular - Palpitations, tachycardia, dysrhythmia, angina
Other - sweating, nausea, vomiting, muscle cramps
Main Uses of Cholinergic Drugs urinary tract
Increase in ureteral peristalsis and contraction of the detrusor muscle.
What are Alpha 1 Adrenergic Adverse Effects?
CNS - headache, restlessness, excitement
Cardiovascular - Palpitations, tachycardia, hypertension, dysrhythmias
Other - necrosis (death of cells in tissue/organ) if IV infiltrates
cause an excitatory response ( except intestinal relaxation)
Catecholamine combined with alpha - adrenergic receptors
