ionized drug

基本解释

Thus, drug penetration may be attributed mostly to the un-ionized form.
因此，药物穿透主要是由非解离型来完成的。

Acids are absorbed faster in the intestine than in the stomach, apparently contradicting the hypothesis that un-ionized drug more readily crosses membranes.
酸性药物在肠中的吸收较胃中快，这显然与非解离药物更易透过细胞膜这一假设相矛盾。
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.
当这种弱酸性药物经口服给药时，胃与血浆之间的非解离型药物浓度梯度很大，从而有利于透过胃粘膜扩散。
