Pharmacology of Ganglion-Acting Drugs

What is a primary action of ganglion-stimulating drugs?

Which of the following can be classified as ganglion-blocking drugs?

What effect do ganglion-blocking drugs primarily have on the cardiovascular system?

Which drug has a therapeutic use to assist in smoking cessation?

What is a characteristic effect of ganglion-stimulating drugs on gastrointestinal activity?

Ganglion-Stimulating Drugs

Nicotine, DMPP, and other compounds stimulate both sympathetic and parasympathetic ganglia, leading to complex physiological effects.
These effects include tachycardia (increased heart rate), increased blood pressure, variable effects on gastrointestinal motility and secretions, and increased bronchial, salivary, and sweat secretions.
The only therapeutic use for ganglion-stimulating drugs is Nicotine, which can be used to assist in smoking cessation.

Ganglion-Blocking Drugs

Hexamethonium and Trimetaphan are examples of ganglion-blocking drugs that block all autonomic ganglia, including the enteric ganglia.
Blocking autonomic ganglia leads to:
- Hypotension (low blood pressure) and loss of cardiovascular reflexes.
- Inhibition of secretions.
- Gastrointestinal paralysis.
- Impaired micturition (difficulty urinating).
Ganglion-blocking drugs are rarely used clinically, except for Trimetaphan, which is used occasionally to produce controlled hypotension during anesthesia.
