Clinical Trial Summary

Purpose of study: Establishing population pharmacokinetic - pharmacodynamic models of chronic disease therapeutics for smoking patients to investigate the effects of gender, age, body weight, liver function, kidney function, nicotine, polycyclic aromatic hydrocarbon related metabolic enzymes and drug related metabolic enzymes gene polymorphism on steady-state drug concentration and efficacy in chronic smoking patients after taking drugs. Object of study: Smoking and non-smoking patients taking levamlodipine besylate tablets or metformin sustained-release tablets.
