Ganglionic stimulants and blockers Flashcards
ganglionic agents are primarily made from what stimulant
nicotine
Only ganglionic drug used
mecamylamine
low dose nicotine effects on physiology of human body
stimulator of nicotinic receptor
high dose nicotine effects on physiology of human body
Inhibits nicotinic receptor signalling leading to desensitization of receptors
What occurs when Nicotine increase at nicotinic receptor sites
increase response then suppresses the signaling from nicotinic receptors
Nicotine effects on which nicotinic receptors
- CNS: neuronal brain subtype
- Cardiovascular and GI: subtype in autonomic ganglia
- Muscular subtype in neuromuscular junctions
ALL NICOTINIC RECEPTORS
2 phases of nicotine poisoning
- Stimulatory phase
- Depressor phase
Stimulatory phase symptoms
-Nausea/vomitting
- sweating
- seizures
-excessive salvation
-headache
-hypertension
-tachycardia
- tremor
- ETC negative impacts
Depressor phase symptoms
Basically the opposite
- hypotension
- bradycardia
- respiratory failure
- difficulty breathing
- muscle weakness
- coma
- CNS depression
Diaphragm paralysis
green tobacco sickness
nicotine poisoning that occurs while handling tobacco plants. High risk with clothing absorption
green tobacco sickness symptoms
Nausea, vomitting, headaches, difficulty sleeping/eating, dizziness
-similar to heat illness and organophosphate posioning
fatal dose of nicotine
60mg in a adult
what makes nicotine posinoning in the body so difficult to acheive
Nicotine is metabolized very rapidly and inactivated.
What drug to give when cardiovascular symptoms arise from nicotine poisoning
Norepinephrine
What must be done to a patient if CNS and skeletal muscle symptoms such as respiratory paralysis occur
Give patient artificial ventilation.
