吸附剂如药用炭等,具有强力的吸附作用,而且沒有选择性,除能吸附腸内細菌产生的毒素和气体外,并能吸附大多数的有机药物如維生素、激素、抗菌素和生物硷等,故合霉素或黄連素如与吸附剂同服,根据服量多寡,可能部分或全部被吸附而不能达到預期的作用, Adsorbents such as medicinal charcoal have a strong adsorption effect and are not selective. They can adsorb toxins and gases produced by intestinal bacteria, and can adsorb most organic drugs such as vitamins, hormones, antibiotics, and biological glycosides. Therefore, if the total dose of methamphetamine or berberine is the same as that of the adsorbent, it may be partially or totally adsorbed and cannot achieve the desired effect depending on the amount of the drug.
