Trulance (PLECANATIDE)
Trulance works by stimulating the guanylate cyclase-C receptor to increase fluid secretion in the intestines.
Plecanatide (Trulance), marketed by Salix, is a chronic idiopathic constipation treatment that stimulates the guanylate cyclase-C receptor to increase intestinal fluid secretion. Its key competitive advantage lies in its mechanism of action and the patent protection until 2028, which provides a strong barrier to entry. The primary risk is the presence of multiple same-class competitors, including linaclotide, lubiprostone, and prucalopride, all of which have varying degrees of patent protection and market presence.

Mechanism of action
Plecanatide is structural analog of human uroguanylin, and similarly to uroguanylin, plecanatide functions as guanylate cyclase-C (GC-C) agonist. Both plecanatide and its active metabolite bind to GC-C and act locally on the luminal surface of the intestinal epithelium. Activation of GC-C results in an increase in both intracellular and extracellular concentrations of cyclic guanosine monophosphate (cGMP). Elevation of extracellular cGMP has been associated with decrease in the activity of pain-sensing nerves in animal models of visceral pain. Elevation of intracellular cGMP stimulates secretion of chloride and bicarbonate into the intestinal lumen, mainly through activation of the cystic fibrosis transmembrane conductance regulator (CFTR) ion channel, resulting in increased intestinal fluid and accelerated transit. In animal models, plecanatide has been shown to increase fluid secretion into the gastrointestinal (GI) tract, accelerate intestinal transit, and c
