Study Notes
Anti-Nicotinic Drugs
- Ganglion-blockers and neuromuscular junction blockers are classified as anti-nicotinic drugs.
Muscarinic Receptor-Blocking Drugs
- Muscarinic antagonists, also known as antimuscarinic, are sometimes referred to as parasympatholytic.
Cholinoceptor-Blocking Drugs
- Cholinoceptor antagonists are divided into two subgroups: muscarinic and nicotinic.
- There are three types of cholinoceptor blockers: non-selective, M1-selective, and ganglia/NMJ.
Effects on the CNS
- Tertiary compounds, such as certain cholinoceptor antagonists, can have central effects.
- When combined with a depolarizing neuromuscular block, the result may be fatal.
This quiz covers the properties and effects of ganglion-blockers, neuromuscular junction blockers, and muscarinic receptor-blocking drugs. Test your knowledge of these anti-nicotinic and antimuscarinic medications.
