PHARMACOKINETIC DYNAMICS AND AGE-STRATIFIED TOLERABILITY OF IRON FORMULATIONS: A COMPARATIVE ANALYSIS ACROSS PEDIATRIC, ADULT, AND GESTATIONAL COHORTS

Аннотация

The clinical management of iron deficiency anemia requires precise pharmacological tailoring based on age-dependent gastrointestinal physiology and systemic metabolic demands. This study investigates the differential pharmacokinetics, bioavailability, and gastrointestinal tolerability of varied iron formulations across distinct patient demographics, specifically focusing on pediatric, adult, and pregnant cohorts. A controlled longitudinal analysis was conducted to evaluate how metabolic shifts, such as pregnancy-induced hepcidin fluctuation and pediatric mucosal absorption rates, dictate the therapeutic efficacy of conventional ferrous salts versus advanced liposomal iron variants. The findings empirically demonstrate that standard unencapsulated iron salts induce significantly disparate mucosal toxicity profiles depending on the physiological state of the patient, whereas targeted liposomal delivery systems mitigate these age-specific adverse events while sustaining optimal hematological recovery. The study concludes that contemporary clinical pharmacology must transition toward life-stage-specific prescribing algorithms to maximize hematopoiesis and minimize iatrogenic gastrointestinal morbidity.
