Pharmaceuticals (Basel) 2024; 17:616. [PMID: 38794186 PMCID: PMC11124061 DOI: 10.3390/ph17050616] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2024] [Revised: 04/17/2024] [Accepted: 05/08/2024] [Indexed: 05/26/2024] Open
Abstract
The management of chemotherapy-induced nausea and vomiting (CINV) in children remains challenging due to differences in the chemotherapy regimens, their relative emetogenicity compared to that in adults and differences in drug metabolism and the available formulations. The common four classes of anti-emetics used for the treatment and prophylaxis of CINV in children include dexamethasone, neurokinin-1 receptor antagonists, 5-hydroxytryptamine-3 receptor antagonists (5HT3RAs), and olanzapine. The appropriate dose of dexamethasone for CINV prophylaxis in children is unknown, with a significant variability in dosage ranging between 6 and 32 mg/m2/day. The dose of dexamethasone is decreased by 30% when this drug is combined with (fos)aprepitant in children, in contrast to a decrease of 50% required in adults. The use of aprepitant in younger children (<12 years) is often hampered by the non-availability of oral suspension formulations in many countries; alternatively, 80 mg capsules are administered for 1-3 days in certain institutes to children weighing between 15 and 40 kg. Among the different 5HT3RAs, palonosetron is comparatively metabolized faster in children than in adults, requiring a higher dosage for similar efficacy to that achieved in adults. Olanzapine is a newer agent, used in doses between 0.1 and 0.14 mg/kg/day in children, with good anti-emetic efficacy, but has sedation and hyperglycemia as concerning adverse effects. Drug interactions between anti-emetics and between anti-emetics and chemotherapy/supportive agents (azole antifungals, cyclosporine, arsenic trioxide), especially QTc prolongation, should be considered during prescription.

J Clin Pharmacol 2023; 63:307-313.

Abstract
Pediatric extrapolation plays a key role in the availability of reliable pediatric use information in approved drug labeling. This review examined the use of pediatric extrapolation in studies submitted to the US Food and Drug Administration and assessed changes in extrapolation approaches over time. Pediatric studies of 125 drugs submitted to the US Food and Drug Administration that led to subsequent pediatric information in drug labeling between 2015 and 2020 were reviewed. The use of pediatric extrapolation for each drug was identified and categorized as "complete," "partial," or "no" extrapolation. Approaches to pediatric extrapolation of efficacy changed over time. Complete extrapolation of efficacy was the predominantly used approach. "Complete," "partial," or "no" extrapolation was used for 51%, 23%, and 26% of the drugs, respectively. This represents a shift in extrapolation approaches when compared to a previous study that evaluated pediatrics drug applications between 2009 and 2014, which found complete, partial, or no extrapolation was used for 34%, 29%, and 37% of the drugs, respectively. Pediatric extrapolation approaches may continue to shift as emerging science fills gap in knowledge of the fundamental assumptions underlying this scientific tool. The international community continues to collaborate on discussions of pediatric extrapolation of efficacy from adults and other pediatric subpopulations to optimize its use for pediatric drug development.

Pediatr Blood Cancer 2020; 67:e28716. [PMID: 32970373 DOI: 10.1002/pbc.28716] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2020] [Revised: 08/26/2020] [Accepted: 08/28/2020] [Indexed: 12/23/2022]
Abstract
A systematic review was undertaken to describe dexamethasone doses studied for chemotherapy-induced vomiting (CIV) prophylaxis in pediatric patients and their effects on achieving complete acute CIV control. No dose-finding studies were identified. However, 16 studies assessing pediatric patients who received dexamethasone were included and classified according to the emetogenicity of chemotherapy administered. Eight different total daily dexamethasone doses were administered to patients on day 1 of highly emetogenic chemotherapy: three in conjunction with aprepitant/fosaprepitant plus a 5HT3 antagonist and five in conjunction with a 5HT3 antagonist. Five different total daily dexamethasone doses were administered in conjunction with a 5HT3 antagonist to patients on day 1 of moderately emetogenic chemotherapy. Due to the heterogeneity of studies identified, meta-analysis was not possible. The optimal dexamethasone dose to control acute CIV and to minimize harms in pediatric patients remains uncertain. This is a key area for future research.
