Autonomic Nervous System
- Adrenergic Pharmacology
- A Receptors
- A1- Adrenerrgic antagonists
- MOA: Bind to A1 receptors, blocking SNS response
- eg. prazosin
- use: hypertension, peripheral vascular disease
- AE: hypotension, frequent urination
- A1- Adrenergic agonists
- MOA: Bind to A1 receptors, stimulating SNS response
- eg. phenylephrine
- use: hypotension, nasal congestion, red eyes
- Adverse effects: hypertension, blurred vision
- A2- Agonists
- MOA: bind to A2 receptors, stopping release of catecholamines
- eg. clonidine
- use: hypertension
- AE: dizziness, drowsiness, dry mouth/nose
- B Receptors
- B1- Adrenergic agonists
- MOA: binds to B1 receptors, stimulating SNS response
- eg. dobutamine
- use: cardiac arrest, circulatory shock
- AE: hypertension, tachycardia
- B2-Adrenergic agonists
- MOA: binds to B2 receptors, stimulating SNS response
- eg. salbutamol, salmeterol
- use: COPD, asthma
- AE: tremor, tachycardia, ^ Blood glucose
- B-Antagonists/ Beta blockers
- MOA: bind to B receptors, blocking SNS response
- eg. carvedilol
- use: cardiac disease, hypertension
- AE: dizziness lethargy, insomnia
- Non selective Adrenergic agonists:
- Bind to A and B receptors, stimulating SNS response
- eg. adrenaline, noadrenaline, dopamine
- Use: cardiac arrest, hypotension, shock
- Cholinergic Pharmacology
- Muscarinic Receptors
- Agonists
- eg. acetylcholine
- MOA: binds to muscarinic receptors, stimulating PNS response
- use: miotics
- AE: problems with eye accomadation
- Antagonists
- eg. atropine
- MOA: bind to muscarinic receptors, Blocking PNS response
- use: pre-med, dilation of pupils
- AE: dry mouth, blurred vision
- Nicotinic Receptors
- Antagonists
- eg. vecuronium
- MOA: binds to nicotine receptors, blocking ACh binding
- use: pre-med
- AE: decreased BP
- Agonists
- eg. suxamethonium
- MOA: mimicts ACh & binds to nicotinic receptors
- use: short acting muscle relaxant
- AE: muscle spasm, hyperkalemia
