ionized drug

基本解釋

Thus, drug penetration may be attributed mostly to the un-ionized form.
因此，葯物穿透主要是由非解離型來(lái)完成的。

Acids are absorbed faster in the intestine than in the stomach, apparently contradicting the hypothesis that un-ionized drug more readily crosses membranes.
酸性葯物在腸中的吸收較胃中快，這顯然與非解離葯物更易透過(guò)細(xì)胞膜這一假設(shè)相矛盾。
When the weak acid is given orally, the concentration gradient for un-ionized drug between stomach and plasma tends to be large, favoring diffusion through the gastric mucosa.
儅這種弱酸性葯物經(jīng)口服給葯時(shí)，胃與血漿之間的非解離型葯物濃度梯度很大，從而有利於透過(guò)胃粘膜擴(kuò)散。
