The effect of sparkling water on the systemic pharmacokinetics of paracetamol in older adults.

Paracetamol absorption kinetics show considerable variability in older adults, complicating the development of effective dosing regimens in the advanced-age population. In previous research, sparkling water has been shown to influence absorption-related processes. This study aimed to apply these findings to older adults and investigate the impact of sparkling water on absorption-related variability and early exposure.

The impact of advanced age on gastrointestinal characteristics that are relevant to oral drug absorption: An AGePOP review.

The purpose of this review is to summarize the current knowledge on three physiological determinants of oral drug absorption, i.e., gastric emptying, volumes and composition of luminal fluids, and intestinal permeability, in the advanced age population, so that potential knowledge gaps and directions for further research efforts are identified.
