PHARMACEUTICAL DEVELOPMENT AND TECHNOLOGY, 2024 (SCI-Expanded)
Pharmaceutical excipients are indispensable components of drug formulations, playing critical roles in enhancing stability, improving bioavailability, and ensuring patient compliance. In pediatric and geriatric populations, the selection of these excipients becomes even more crucial due to their unique physiological and pharmacokinetic profiles, as well as age-specific formulation requirements. This review examines the functions, safety considerations, and potential adverse effects of excipients in these vulnerable groups. It addresses the challenges of drug formulation for neonates, infants, and elderly patients, including immature enzyme systems, polypharmacy, and swallowing difficulties. The impact of excipient-excipient and excipient-active pharmaceutical ingredient (API) interactions on drug stability, efficacy, and safety is also highlighted. For instance, the effects of polyethylene glycol (PEG) in patients with impaired renal function and destabilizing interactions between surfactants and protein-based APIs are analyzed. Additionally, current guidelines and safety requirements from regulatory bodies such as the FDA, EMA, and ICH are reviewed. This paper emphasizes the importance of carefully selecting excipients that balance functionality and safety to ensure therapeutic efficacy while minimizing risks for pediatric and geriatric patients. Future directions in excipient development and formulation strategies are also discussed to improve treatment outcomes for these populations.
