How Does Linzess Work for Constipation?
Linzess is a guanylate cyclase-C (GC-C) agonist. By activating GC-C in the intestinal wall, it increases the secretion of chloride and bicarbonate into the intestinal lumen. This fluid increase helps soften stool and speeds its passage through the intestines, thereby reducing abdominal pain associated with IBS-C [1].
What Other Medications Treat IBS-C in Canada?
Other medications approved in Canada for IBS-C include lubiprostone (Amitiza) and plecanatide (Trulance). These drugs also work by increasing intestinal fluid secretion but through different mechanisms [3].
What Are the Potential Side Effects of Linzess?
The most common side effect reported with Linzess is diarrhea [1]. Other potential side effects include flatulence, abdominal distension, and abdominal pain [4].
Can Linzess Be Prescribed for Other Conditions?
While Linzess is specifically approved for IBS-C and CIC in Canada, its mechanism of action might be explored for other gastrointestinal motility disorders, though such uses would be off-label and require careful consideration by a healthcare professional [1].
How is Linzess Regulated in Canada?
Linzess is approved and regulated by Health Canada. This involves rigorous review of safety and efficacy data before market authorization [1].
