Oral doses of 0.5 mg/kg achieved AUCs of 645 ± 249 ng-hr/mL and 580 ± 60 ng-hr/mL in pediatric patients <1 year of age (N=5) and in pediatric patients 11 to 15 years of age, respectively, compared to 482 ± 181 ng-hr/mL in adults treated with 40 mg orally.Pharmacodynamics of famotidine were evaluated in 5 pediatric patients 2 to 13 years of age using the sigmoid E* Serum concentration of famotidine associated with 50% maximum gastric acid reduction.
