facilitated diffusion

Drugs may cross a biologic barrier by passive diffusion, facilitated passive diffusion, active transport, or pinocytosis.

药物可通过被动扩散 、 易化被动扩散 、 主动转运或胞饮作用等方式穿越生物屏障.

Their absorption was first-order process besides the passive diffusion mechanism, and facilitated diffusion and active transport may also take part in the transport process.

With the decrease of sanchinoside R_ ( 1) and ginsenoside Rg_1 concentration, the absorption rate is increased, their absorption was is first-order process, besides the passive diffusion mechanism, facilitated diffusion and active transport may also take part in the transport process.

其吸收速率随着浓度的增加而逐渐减小，药物在小肠中的吸收不呈现一级动力学过程，吸收机制除了被动扩散以外，可能还有易化扩散和主动转运；
