Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Propofol is a widely used sedative anesthetic, but there are large individual differences, which making different patients with different sensitivity to propofol. The aim of this study was to analyze the effects of age, height, body weight, Drinking, metabolic enzymes CYP2B6 and UGT1A9 on Pharmacological effects and pharmacokinetics of propofol, and to provide a reasonable reference for clinical anesthesia patients and evidence for individual dosage regimens.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Propofol is a widely used sedative anesthetic, but there are large individual differences, which making different patients with different sensitivity to propofol. In recent years, the concept of individualized administration came into being.Individual administration refers to according to the condition of patients,the drug's safety and efficacy, and pharmacokinetics, pharmacodynamics and clinical response ,then gives different dosing regimens for individual patients and promotes the development of rational drug use. Different people have differences metabolism of propofol, reported in the literature, genetic polymorphism, demographic characteristics, combined with drug and other variability factors, all of them will affect the pharmacokinetics and pharmacodynamics of propofol.The aim of this study was to analyze the effects of age, height, body weight, Drinking, metabolic enzymes CYP2B6 and UGT1A9 on Pharmacological effects and pharmacokinetics of propofol, and to provide a reasonable reference for clinical anesthesia patients and evidence for individual dosage regimens.
