    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.
