What Are Drugs That Decrease GI Smooth Muscle Tone?

Definition and Mechanism of Action

Drugs that decrease GI smooth muscle tone act by relaxing the smooth muscles lining the GI tract, thereby reducing motility and spasm. They are primarily used to treat conditions characterized by hypermotility or spasticity such as:

• Irritable bowel syndrome with predominant diarrhea (IBS-D)
• Functional bowel disorders
• Hemorrhoids and anal fissures
• Certain forms of gastroesophageal reflux disease (GERD)

Pharmacological Classes

Common drug classes include:

Class	Examples	Mechanism of Action	Indications
Antispasmodics	Dicyclomine, Hyoscine (Scopolamine)	Muscarinic receptor blockade	Spastic IBS, cramps
Calcium Channel Blockers	Nifedipine, Verapamil	Block calcium influx in smooth muscle cells	Spasm relief, anal fissures
Botulinum Toxin	OnabotulinumtoxinA	Inhibit acetylcholine release	Severe hypertonic conditions
Benzodiazepines	Diazepam	Central muscle relaxation	Spastic motility
