Plecanatide Research Dosage: Published Protocol Reference
Plecanatide dosage references vary by route and study context. The database lists Oral: 3 mg, Once daily. These are research-context references, not a universal protocol.
Direct Answer
Plecanatide (Trulance) is FDA-approved for chronic idiopathic constipation and IBS with constipation, with Phase 3 RCTs demonstrating consistent efficacy on validated endpoints. As a uroguanylin analog that works locally in the GI tract with minimal systemic absorption, it has an excellent safety profile. For guanylate cyclase-C agonist research and IBS-C/CIC treatment, it is a validated option alongside linaclotide.

Research Dosage References
- <strong>Oral</strong> - 3 mg - Once daily - FDA-approved dose for both CIC and IBS-C. Take with or without food. Tablet should be swallowed whole or crushed and mixed with applesauce or water.
Half-Life
Minimal systemic absorption (acts locally in GI tract; plasma concentrations are below quantifiable levels).

Dosage entries are compiled from labels, published studies, and research-context references where available. For Plecanatide, the evidence grade is Level A, and the current research status is FDA Approved.
Safety Signals
- Contraindicated in patients under 6 years of age (risk of serious dehydration)
- Avoid use in patients 6 to less than 18 years of age
- Discontinue if severe diarrhea occurs
- Minimal systemic absorption limits drug interactions but does not eliminate them
