Tegaserod

Introduction: What is Tegaserod?

Tegaserod is a medication used to treat chronic idiopathic constipation (CIC) in adults under 65 years who lack adequate response to other therapies. It was previously used for IBS-C in women under 65 but is no longer indicated for that.

Uses of Tegaserod

Tegaserod is approved for the treatment of:

• Irritable Bowel Syndrome (IBS) with constipation in women under 65 years of age (historical use; no longer indicated).
• Chronic idiopathic constipation (CIC) in adults under 65 years with no response to other laxatives.

These conditions can cause significant discomfort and disruption in daily life, making Tegaserod a valuable option for managing symptoms.

How Does It Work?

Tegaserod works by stimulating serotonin receptors in the gastrointestinal tract. Serotonin is a neurotransmitter that plays a crucial role in regulating bowel movements. By activating these receptors, Tegaserod enhances gut motility, which helps to move food through the intestines more effectively. This action can relieve constipation and reduce abdominal pain associated with IBS.

Dosage and Administration

The standard dosage for adults is (for CIC only):

• Irritable Bowel Syndrome (IBS): 6 mg taken orally twice daily before meals (obsolete).
• Chronic Idiopathic Constipation (CIC): 6 mg taken orally twice daily before meals. Discontinue after 4-12 weeks if no response.

Tegaserod is available in tablet form and should be swallowed whole with water. It is not recommended for use in children.

Side Effects of Tegaserod

Common side effects may include:

• Diarrhea

• Nausea

Serious side effects, though less common, can include:

• Cardiovascular events (e.g., heart attack, stroke)
• Ischemic colitis (reduced blood flow to the intestines)

• Heart problems

Patients should report any unusual or severe symptoms to their healthcare provider immediately.

• Antidepressants (especially SSRIs)
