title: Simethicone in the treatment of infant colic: a randomized, placebo-controlled, multicenter trial.
abstract: OBJECTIVE
  To determine the efficacy of simethicone in the treatment of infant colic.
  
  
  METHODS
  Randomized, double blind, placebo-controlled.
  
  
  METHODS
  Three general pediatric practices in distinct geographic regions.
  
  
  METHODS
  Eighty-three infants between 2 and 8 weeks of age with infant colic.
  
  
  METHODS
  Treatment with simethicone and placebo in double blind crossover fashion.
  
  
  RESULTS
  A total of 166 treatment periods, ranging from 3 to 10 days, were evaluated in the 83 infants. Compared to baseline, improvement in symptoms was reported for 54% of the treatment periods, worsening was reported for 22%, and, for 24%, there was no change. The likelihood of the treatment period being rated as showing improvement, worsening, or no change was the same whether the infant was receiving placebo or simethicone. Twenty-eight percent of he infants responded only to simethicone, 37% only to placebo, and 20% responded to both. No statistically significant differences were noted among these three groups of responders. No difference could be shown even when infants with "gas-related symptoms" (by parental report) were separated out as a group.
  
  
  CONCLUSIONS
  Although both produced perceived improvements in symptoms, simethicone is no more effective than placebo in the treatment of infantile colic.
