A: Atropine makes them that way! Atropine is an anti-muscarinic agent that acts on M1 receptors in the CNS, M2 receptors in the heart, and M3 receptors in smooth muscle tissue and various glands. The drug can be used to treat bradycardia, cholinesterase inhibitor overdose, and mild cramping and urgent bladder in mild cystitis. The side effects of atropine can be remembered by the mnemonic:
- Red as a beet - Dilation of superficial vessels leads to flushing
- Blind as a bat - Cycloplegia and mydriasis
- Dry as a bone - Decreased lacrimation and salivation
- Hot as a hare - Atropine fever due to decreased perspiration
- Mad as a hatter - Delirium and hallucinations
