HOSPITALIZED MALE CHILDREN WITH ACUTE DIARRHOEA
STUDY DESIGN. Randomized, double-blind, placebo-controlled study with 2 parallel groups
OBJECTIVE. To assess the efficacy and safety of racecadotril as an adjunct to oral rehydration
therapy for children with acute watery diarrhea
TEST PRODUCTS . Racecadotril : 1.5 mg/kg, 3 times a day, every 8 hours (granulated powder) until
diarrhea stops or for a maximum of 5 days
EFFICACYMajor end point: 48-stool output (per kg of patient weight at inclusion)Other end points:. Total stool output i.e. sum of stool weights until diarrhea stops or during 5 days
(for patients not cured during 5 days). Duration of diarrhea. Number of cured patients. Total ORS intake
(A subgroup of patients with rotavirus was analysed separately according to the same criteria)
Salazar-Lindo E, Santisteban-Ponce J, Chea-Wood E and Guterriez M. N Engl J Med 2000;343:463-467

SAFETY. Frequency of adverse events reported as per CRF
CRITERIA FOR INCLUSION. Acute diarrhea requiring hospitalization (because of some level of dehydration to be
corrected during the initial 4-6 hours)
. Diarrhea defined as 3 or more liquid stools during the last 24 hours and at least one during the observation period
. Excluding patients with diarrhea lasting for more than 5 days, blood in stools, severe
dehydration (requiring IV therapy) and other illness
Number of planned patients: 2 x 68
Number of analyzed cases :. Intention to treat analysis: 135 (all the patients that were randomized and treated). Per protocol analysis: 117 cases

There was no significant difference between groups in the
incidence of vomiting or in the total vomitis output.
Twelve patients, seven on racecadotril and five on placebo,
experienced unexpected events while on study medication. Only
four patients (all on racecadotril) had events possibly related to
treatment: mild hypokalaemia (2), ileus (1) and mild fever (1).

RacecadotrilCONCLUSION from RECOMMANDATIONS in
“Drug therapy of infant and child infectious acute diarrhea” * :
Gastro-paediatricians from: Algeria, Belgium, Canada, Congo, Croatia, France, Gabon, Italy, Lebanon, Morocco, Romania, Spain, Switzerland, Syria, Tunisia, Turkey & Vietnam
Rehydration is the main objective of AD management
Early food intake (4 hours) should be initiated with previous milk, except specific situations (breast-feeding, etc..)
Among antidiarrheic drugs currently marketed, only very few ones have been properly assessed (DB vsPc, Stool output)

RacecadotrilCONCLUSION from RECOMMANDATIONS in
“Drug therapy of infant and child infectious acute diarrhea” * :
“Le racécadotril est le seul médicament à avoir démontré une diminution significative du débit des selles” =
“ Racecadotril is the only drug that induces a demonstrated and significant decrease in stool output”.
Fast onset of action (24th Hour) and very significant (-60%, p< 0.001) on stool output, including Rotavirus diarrhea,
Other drugs have only a symptomatic effect (if any), and should not be prescribed without family warnings about dehydration.

RacecadotrilEvents following RECOMMANDATIONS in
“Drug therapy of infant and child infectious acute diarrhea” * :
French Health Authorities decided the delisting of many antidiarrheic drugs, including all yeasts (Saccharomyces boulardii, Lactobacillus acidophilus, etc.), clays (Bedelix), coals & coal-derived products (Off. Journal of French Rep., 29 Jan 2006)
The Canadian Paediatric Society included in it’s official guidelines: Racecadotril, an antisecretoty drug, is safe and effective and can be used routinely in children for treatment of watery diarrhea (evidence: level I, B), (Paed Child Health, 7 Sep
2003).
The Racecadotril file has been reassessed by the French Transparency Commission, which upheld the reimbursement status of Tiorfan, (HAS, 7 Sep 2005).
