Aim: To assess racecadotril efficacy, whatever its dose, versus placebo in adult acute diarrhoea. Methods: Individual Patient Data meta-analysis following multilevel mixed models testing of the significance of the treatment effect adjusted for baseline covariates. Diarrhoea duration was the common main criteria. Results: Four randomized clinical trials (n = 669) were identified with raw data. The clinical global impression evaluated at baseline by the physician was found to be the essential predictor influencing the outcome. As compared to placebo, the 100 mg dose, the minimum effective dose, induced a 80% increase of the recovered patient proportion at anytime (Hazard Ratio = 1.8 [1.3, 2.5], p < 0.001), a 60% increase of the responder proportion i.e. recovery within 3 days (p < 0.001), a 47% reduction of abdominal pain and nausea and an overall 33% decrease of sick days (p < 0.001). In conclusion, as compared to placebo, racecadotril induced several significant effects, such as reducing the diarrhoea duration, the number of stools and associated symptoms, leading to less lost productivity.展开更多

Objective: To estimate the effectiveness of RC in the symptomatic treatment of acute diarrhoea in adults. Data Sources: A systematic review of MedLine, Cochrane Controlled Trials Register, DARE, and Embase (up to November 2013). Additional studies were identified by contacting clinical experts and the manufacturer. Study Selection and Appraisal: Randomized Controlled Trials performed in adults suffering from acute diarrhoea using RC in one treatment arm. Independent extraction of articles using predefined data fields, and methodological quality measurement assessment. All randomised trials performed in adults suffering from acute diarrhoea with RC as the studied group. Statistics: The main efficacy endpoint was diarrhoea duration defined as time to recovery compared between groups by survival techniques and converted into hazard ratio (HR). We exclusively used a random-effect meta-analytic model. Constipation proportion was the main safety endpoint, evaluated between treatments by the Relative Risks (RR). Results: Twelve randomised trials (2619 patients) met inclusion criteria. Duration of diarrhoea was much shorter in the RC group, the proportion of patients having recovered at any time of the treatment period was 65% higher in the RC group, compared with placebo (HR = 1.65 [1.38-1.97], p < 0.00001, n= 1001). Duration of diarrhoea was similar in the RC and loperamide groups (HR = 1.08 [0.95-1.22], p = 0.24, n = 1618). The proportions of constipated patients were similar in the RC and placebo groups 0.95 [0.24-3.68], p = 0.97), however, about 3 times more constipated patients were found in the loperamide group compared with the RC group (RR = 0.34 [0.22-0.51], p to placebo, RC is characterized by a clinically relevant earlier remission of diarrhoea. When compared to loperamide, diarrhoea duration was similar, however, significantly fewer secondary constipation adverse effects were observed.展开更多

Loperamide is an effective anti-diarrheal agent, but it usually induces constipation. This study is to compare the efficacy, safety, and tolerability of racecadotril versus Ioperamide in the outpatient treatment of acutediarrhea in adults.METHODS: A two-center, randomized, parallel-group,single-blind study was carried out to compare the efficacy,tolerability, and safety of racecadotril (100 mg thrics daily) and Ioperamide (2.0 mg 2 twics daily) in 62 adult patients suffering from acute diarrhea. The main efficacy criterion used was the duration of diarrhea after beginning the treatment (in hours). Other signs and symptoms werealso evaluated.RESULTS: The clinical success rates for these antidiarrheal treatments were 95.7% and 92.0% for racecadotril and Ioperamide respectively. Patients on racecadotril had a median duration of diarrhea of 19.5 h compared with a median of 13 h for patients on Ioperamide.Rapid improvement in anal burn and nausea was found for each drug. However, more patients on Ioperamide suffered from reactive constipation (29.0% vs 12.9%).Itching, another adverse event was notably higher in the racecadotril group (28.6% vs 0%). With regard to other adverse events, the two medications showed similar occurrence rates and similar concomitant medicationusage rates.CONCLUSION: Racecadotril and Ioperamide are rapid,equally effective treatments for acute diarrhea in adults,but Ioperamide treatment is associated with a higher incidence of treatment-related constipation.展开更多
