Multicenter, 4-Week, Double-Blind, Randomized, Placebo-Controlled Trial of Lubiprostone, a Locally-Acting Type-2 Chloride Channel Activator, in Patients With Chronic Constipation

Abstract

In patients with chronic constipation, treatment with lubiprostone produces a BM in the majority of individuals within 24-48 h of initial dosing and improves the frequency as well as other characteristics associated with BMs with short-term (i.e., 4 wk) treatment. The most commonly reported adverse event was mild to moderate nausea, which resulted in treatment discontinuation in 5% of treated patients.
