生病时吃下去的药被吸收了多少,您可能未曾注意过。不同药物被人体吸收、利用程度干差万别,这与药物的性质、服药方法等有关。如果我们能为药物铺平道路,清扫障碍,药物吸收便可一路畅通。药物的吸收过程,有点像我们坐车上班的过程。如果我们是药物分子,那药片等口服剂型就是我们的车。药物进入胃肠道,就像我们开车上了路,而我们上班的地方是小肠(多数药物吸收的主要部位)。到了小肠,我们必须从车上下来(药物以分子形式释放出来),跨进单位大门(药物以分子形式跨过肠上皮细胞 How much of the medicine you eat when you get sick is something you may not have noticed before. Different drugs are absorbed by the body, the extent of the use of different, which is related to the nature of the drug, medication and so on. If we can pave the way for drugs and clean up the barriers, the absorption of drugs will be smooth all the time. Drug absorption process, a bit like we go to work by car. If we are drug molecules, that oral dosage forms such as pills is our car. Drugs enter the gastrointestinal tract just as we drove, and the place where we work is the small intestine (the main site for most drug absorption). To the small intestine, we have to get out of the car (the drug is released in molecular form) and into the unit’s door (the drug molecularly spans the gut epithelium
