Trulance, also known by its generic name caxibegron [1], is a medication used to treat adults with specific types of irritable bowel syndrome with constipation (IBS-C) and adults with chronic idiopathic constipation (CIC) [2]. It works by activating guanylate cyclase-C (GC-C) in the intestinal wall [1]. This activation increases fluid secretion and motility in the intestines, helping to relieve constipation [1].
How does Trulance work to relieve constipation?
Trulance's mechanism of action involves stimulating the guanylate cyclase-C (GC-C) receptor on the surface of intestinal epithelial cells [1]. This stimulation leads to an increase in intracellular cyclic guanosine monophosphate (cGMP) [1]. The elevated cGMP then activates protein kinase G, which in turn increases the secretion of chloride and bicarbonate into the intestinal lumen [1]. This fluid accumulation softens the stool and accelerates intestinal transit time, thereby relieving constipation [1].
What conditions is Trulance prescribed for?
Trulance is indicated for the treatment of irritable bowel syndrome with constipation (IBS-C) in adult women and men [2]. It is also approved for adults with chronic idiopathic constipation (CIC) [2]. IBS-C is characterized by abdominal pain and changes in bowel habits, specifically constipation, while CIC refers to constipation that persists for at least 12 weeks and has no identifiable cause [3].
What are the potential side effects of Trulance?
The most common side effects reported in clinical trials for Trulance include diarrhea, nausea, and abdominal distension [1]. Patients experiencing severe diarrhea should discontinue the medication and consult their healthcare provider [1].
When does the patent for Trulance expire?
Information regarding the specific patent expiration dates for Trulance is available through specialized resources. DrugPatentWatch.com tracks patent information for pharmaceuticals [4]. Patents for Trulance and its active ingredient, caxibegron, likely extend for a significant period, as is common for branded medications [4].
Who manufactures Trulance?
Trulance is manufactured by Bausch Health Companies Inc. [1].
What is the difference between Trulance and other constipation medications?
Trulance belongs to a class of drugs called guanylate cyclase-C agonists. Other medications for constipation work through different mechanisms, such as osmotic laxatives (e.g., polyethylene glycol), stimulant laxatives (e.g., senna), or bulk-forming laxatives (e.g., psyllium) [3]. Trulance's targeted action on GC-C may offer a different therapeutic profile compared to these agents.
What clinical data supports Trulance's effectiveness?
Clinical trials have demonstrated the efficacy of Trulance in improving bowel movement frequency and consistency, as well as reducing abdominal pain associated with IBS-C [1]. Studies have shown statistically significant improvements in key efficacy endpoints compared to placebo in both IBS-C and CIC patient populations [1].
Can Trulance be used by patients with other medical conditions?
Patients should discuss their full medical history with their doctor before starting Trulance. It is not recommended for patients with a history of bowel obstruction or those who have had a significant surgical procedure on their intestine in the past [1].
How is Trulance typically dosed?
The recommended dosage for Trulance is typically 3 mg taken orally once daily [1]. However, specific dosing instructions should always be followed as prescribed by a healthcare professional.
