Brief Summary

The goal of this observational study aims to reveal the pharmacokinetics of clinical probes and characteristics of endogenous biomarkers for drug-metabolizing enzymes and transporters in Chinese older adults and old older adults, to analyze their correlation with frailty, and to explore the exosome characteristics in this population.

Detailed Description

This study is a non-intervention observational study in Chinese older adults and will not interfere with the routine medical treatment. 6-10 mL whole blood and 20 mL urine samples (only applicable for patients taking meropenem and metformin) will be collected from eligible subjects according to medical routine blood collection time. Concentration of clinical probes and respective metabolites (when required), endogenous biomarkers, genotype information of drug-metabolizing enzymes and transporters, and the exosome characteristics will be quantified or measured.

Eligibility Criteria

Inclusion Criteria

1. Older adults males and females aged 60-74 years old (older adults group) and ≥75 years old (old older adults group), proportion of either sex must not be less than 1/3 (except for subjects taking finasteride), number of subjects in each frailty category must not be less than 10;
