Advances of studies on effect of drug transporter under hypoxia / 中国药理学通报

ABSTRACT

Plateau environment has the characteristic of low ox-ygen and low pressure, which leads to a series of physiological changes and affects the process of drug metabolism in the body. Many factors affect the pharmacokinetic parameters, including gastric emptying, blood rheology, cardiopulmonary function, hepatorenal function, cytochrome P450 enzyme and so on. The present study focuses on drug metabolic enzymes, since drug transporter is the key factor that mediates drugs in their entrance to the body through the cell membrane, producing the curative effect. In order to provide the reference to further research on the effect of plateau hypoxia on pharmacokinetics and guide the rational use of drugs, we review in this paper the classification of the transporter, mediated drug substrates, the influence of hypoxia on expression levels of drug transporter substrates and the regulatory mechanism of drug transporter under the condition of hypoxia.
