In all the phase III clinical trials in patients with CC and IBS-C, there have been no statistically important differences observed for treatment emerging adverse events amongst the linaclotide group as well as the placebo, except in the Chey et al trial18 in IBS-C individuals (65.four in linaclotide group vs 56.six within the placebo group, p , 0.05). Subsequent post-hoc analyses combining the Rao and Chey trials didn’t show any significance.26 The phase III trials in individuals with CC showed that 16 of sufferers receiving linaclotide 145 g and 14.2 of patients receiving linaclotide 290 g created diarrhea when compared with four.7 inside the placebo manage group.22 In the IBS-C phase III trials, the incidence of diarrhea occurred in roughly 1-in-5 patients, with a quantity required to harm (NNH) of five.8?.five.25 Improve in flatulence (four.9 vs 1.5 , p = 0.0084), and abdominal discomfort (five.four vs 2.5 , p=0.0462) had been also greater within the linaclotide treated group versus the placebo.25 Patients requiredtable 2.
