Autonomic Pharmacology

Question 1

Mimetics vs Lytics

Answer 1

• mimetics = Drugs that mimic

- lytics = Drugs that impair

Question 2

Parasympathetic vs Sympathetic

Answer 2

Parasympathetic: Energy Conserving, use acetylcholine
Sympathetic: Blood to muscle, bronchodilation, cardiac stimulation, use noradrenaline

Question 3

Neurotransmitters

Answer 3

Generally consider two.

Noradrenaline and Acetylcholine. Produced pre and post synaptically.

Question 4

Acetylcholine Neurotransmitter

Answer 4

Postganglionic, ganglia

Question 5

Noradrenaline Neurtransmitters

Answer 5

Are Adrenoreceptors

• a1: sympathetic activations. Increase BP (vasoconstriction, but reflex is slowing HR)
• a2: Reduces sympathetic activity, decreases BP, inhibits noradrenaline release.
• b1: Cardiac stimulants. Rate/Force. Prevent sympathetic induced bronchodilation.
• b2: Relaxes bronchial smooth muscle, leading to bronchodilation.
