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.</p>","PeriodicalId":20004,"journal":{"name":"Pharmaceutical Development and Technology","volume":" ","pages":"1-9"},"PeriodicalIF":2.6,"publicationDate":"2024-12-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142807677","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, complexes of molecular PVP-I with polyethylene glycol-polyvinyl alcohol copolymer (PEG-PVA copolymer) were considered water-soluble iodophors. Two different methods were used to prepare the solids: physical mixtures and kneading. The physical characteristics of the obtained solids were evaluated using several spectroscopic methods. The presence of iodine was confirmed by a potentiometric titration and antimicrobial activity was tested. The results showed that the PEG-PVA copolymer interacted with povidone primarily through hydrogen bonding between the hydroxyl part of the PEG-PVA copolymer and the amide part of povidone with an estimated binding energy of 3.2 kcal/mol. The amide groups polarity in povidone made them more likely to form hydrogen bonds with the PEG-PVA copolymer. Also, the protonated pyrrolidone bonded to the triiodide anions by intermolecular hydrogen bonds, which increased PVP-I solubility in water. The kneading method provided a faster dissolution rate than physical mixing and pure PVP-I.
