In vitro gastrointestinal model (TIM) with predictive power, even for infants and children?
International Journal of Pharmaceutics , Volume 457 - Issue 1 p. 327- 332
There is a need for information on the bioavailability in pediatric patients of drugs from manipulated dosage forms when applied in combination with food and/or co-medication under realistic daily practice circumstances. We describe the development, validation and application of a dynamic, computer-controlled in vitro system mimicking the conditions in the upper gastrointestinal tract of neonates, infants and toddlers: TIMpediatric. Paracetamol and diclofenac in age-related food matrices and with esomeprazole co-medication were tested. The experiments showed relevant results on the impact of drug manipulation and co-medication on the availability for absorption of active compounds. Without ethical constraints, alternative approaches for oral dosing and new pediatric formulations can be studied in TIMpediatric with a high predictive value.
