Video from Pixorize on YouTube

Describe muscarinic antagonists (atropine, hyoscine, ipratropium, tropicamide, oxybutynin): effects, uses and adverse effects; recognise anticholinergic toxicity.

Why this video

It uses a clear visual mnemonic to explain the clinical uses, adverse effects, contraindications, and physostigmine reversal of atropine and systemic anticholinergic blockade.

Part of this line

Covers part of this objective. It leaves out: It focuses solely on atropine, leaving out hyoscine, ipratropium, tropicamide, and oxybutynin as well as the full classic anticholinergic toxidrome mnemonic.

Heads up

It is geared towards NCLEX prep and does not explain muscarinic receptor subtypes or the presynaptic mechanism behind low-dose paradoxical bradycardia.
