Autonomic Nervous System Drugs

Question 1

It transmits impulses from the CNS out to the peripheral organs to cause an effect or action.

Answer 1

AFFERENT

Question 2

It receives impulses, transmits through the spinal cord to effector organ cells.

Answer 2

EFFERENT

Question 3

It is involuntary, controls and regulates the heart, GI, respiratory system, bladder, eyes and glands.

Answer 3

AUTONOMIC NERVOUS SYSTEM/ VISCERAL SYSTEM

Question 4

It is voluntary and connect the CNS with organs and striated muscle to perform our daily functions.

Answer 4

SOMATIC NERVOUS SYSTEM

Question 5

This system helps your body activate its “fight-or-flight” response and the terminal neurotransmitter is norepinephrine.

Answer 5

SYMPATHETIC NERVOUS SYSTEM

Question 6

This system is a network of nerves that relaxes your body after periods of stress or danger the terminal neurotransmitter is acetylcholine.

Answer 6

PARASYMPATHETIC NERVOUS SYSTEM

Question 7

Drugs act through receptors by binding to the receptors to initiate a response or prevent a response.

Answer 7

Receptor Theory

Question 8

What are drugs that produces a response?

Answer 8

Agonist

Question 9

What are drugs that blocks a response?

Answer 9

Antagonist

Question 10

Stimulant compounds which mimic the effects of endogenous agonists of the sympathetic nervous system. Examples of effects include increases in heart rate, force of cardiac contraction, and blood pressure.

Answer 10

Sympathomimetic drugs (also known as adrenergic drugs and adrenergic amines)

Question 11

It is category based on chemical structure that has a catechol ring and amines.

Answer 11

CATECHOLAMINES

Question 12

It is category based on chemical structure that has no catechol ring.

Answer 12

NONCATECHOLAMINES

Question 13

It is the receptor that the stimulation leads to vasoconstriction of the arterioles and pupillary dilation.

Answer 13

Alpha 1 Receptor Agonist

Question 14

It is the receptor that is vital for the normal physiological function of the sympathetic nervous system. When the receptors are stimulated, it increase the heart rate and increase the heart’s strength of contraction or contractility.

Answer 14

Beta 1 Receptor

Question 15

It is also known as adrenaline and plays an important role in your body’s “fight-or-flight” response. Also in metabolism, attention, focus, panic and excitement. Abnormal levels are linked to sleep disorders, anxiety, hypertension and lowered immunity.

Answer 15

EPINEPHRINE

Question 16

Side effects of Adrenergic Agonist.

Answer 16

1. Tissue necrosis–check IV sites frequently
2. Tachycardia, palpitations, tremors, dizziness, increased blood pressure
3. Urinary retention r/t high doses
4. Nausea and vomiting –offer food
5. ANTIDOTE: phentolamine Mesylate (Regitine) for extravasation of norepinephrine and dopamine

Question 17

These drugs help lower blood pressure but also may be used to ease symptoms of an enlarged prostate.

Answer 17

Beta blockers, also known as beta-adrenergic blocking agents.

Question 18

Mimic the parasympathetic neurotransmitter acetylcholine

Answer 18

CHOLINERGIC AGONISTS

Question 19

Agents that decrease or block the actions of acetylcholine on its parasympathetic nervous system receptors on smooth muscle cells, glands and the central nervous system.

Answer 19

ANTI-CHOLINERGIC AGENTS

Question 20

A ganglionic blockers that stimulate and block cholinergic function but it is not useful in clinical practice.

Answer 20

NICOTINE
