ionized drug

基本解釋

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

Acids are absorbed faster in the intestine than in the stomach, apparently contradicting the hypothesis that un-ionized drug more readily crosses membranes.
酸性藥物在腸中的吸收較胃中快，這顯然與非解離藥物更易透過細胞膜這一假設相矛盾。
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.
當這種弱酸性藥物經(jīng)口服給藥時，胃與血漿之間的非解離型藥物濃度梯度很大，從而有利于透過胃粘膜擴散。
