Linzess 145 mcg capsule is a prescription medication primarily used to treat two common gastrointestinal disorders: irritable bowel syndrome with constipation (IBS-C) and chronic idiopathic constipation (CIC). The active ingredient in Linzess is linaclotide, a guanylate cyclase-C agonist that works by increasing the amount of fluid in the intestines and promoting regular bowel movements. Understanding the uses, benefits, and potential side effects of Linzess is crucial for patients and healthcare providers to make informed decisions about its use.
Primary Uses of Linzess 145 mcg Capsule
Linzess is approved by the FDA for two main indications:
- Irritable Bowel Syndrome with Constipation (IBS-C): Linzess helps alleviate abdominal pain and improve bowel habits in patients with IBS-C.
- Chronic Idiopathic Constipation (CIC): For patients suffering from CIC, Linzess increases bowel movement frequency and improves stool consistency.
Mechanism of Action
The mechanism of action of linaclotide involves the activation of guanylate cyclase-C receptors in the intestinal epithelium. This activation leads to an increase in cyclic guanosine monophosphate (cGMP) levels, which in turn increases chloride and bicarbonate secretion into the intestinal lumen. The increased secretion of these ions draws water into the lumen, softening stool and promoting bowel movements.
