Design An intention to treat, double blind, randomised, crossover trial comparing PEZ to placebo for reduction of postprandial IBS-D. Patients had to recognise at least two different triggering foods, be willing to consume six baseline ‘trigger meals’ and again blinded with PEZ and placebo. Patients then chose which drug they preferred for another 25 meals. Setting Outpatient internal medicine practice clinic. Patients 255 patients were screened; 83 met the criteria, including 5 years of symptoms, recognised ‘food triggers’, no other identifiable cause for the symptoms, either a normal colonoscopy or barium enema while symptomatic and able to discontinue all anticholinergic medications. 69 patients were enrolled, 20 withdrew before randomisation, leaving 49 patients: 14 men, 35 women, mean age 52 years (SD 15.3). Over 60% had experienced symptoms for 11–30 years and 16% for more than 40 years. Interventions After completing six baseline meals, patients were randomised in blocks of four to receive either identical PEZ or a placebo for another six meals, and after a washout period of time received the alternative drug. Main outcome measures The primary analysis was number of patients who chose PEZ over placebo for the extended use. Results Overall, 30/49 (61%) would have chosen PEZ (p=0.078), with first drug preference for PEZ at 0.002. Among the PEZ subgroup, PEZ use compared with placebo, demonstrated improvement in all symptoms (p≤0.001) for cramping, bloating, borborygami, urge to defecate, global pain and decrease stooling with increase in stool firmness. Conclusions PEZ was found in a small group of patients to reduce postprandial IBS-D symptoms and deserves further evaluation. ER -
