Delta-8 動(dòng)物胃腸道體內中藥物的溶解度的測定——結論、工具書(shū)類(lèi)!

結論
胃腸道pH值和緩沖容量的種間差異是重要的考慮因素,尤其是對胃腸道給藥的pHresponsive配方和可電離藥物。 因此,兔子和豬的空腸、回腸和近端結腸具有相對較高的緩沖容量,而豬遠端結腸具有較低的緩沖容量是非常重要的考慮因素。 與人相比,大鼠、兔和豬的近端小腸和升結腸的液體的滲透壓和表面張力也較高。 胃腸道特征的這些差異導致潑尼松龍在大鼠體內的溶解度較高(近端結腸除外),而潑尼松龍在豬和兔體內的溶解度與人類(lèi)相當。 因此,如果在大鼠的體液中測量,中性化合物潑尼松龍的溶解度可能被高估。 另一方面,可電離藥物美沙拉秦在兔和豬體內的溶解度在小腸中部高于人,在結腸中低于人,僅在小腸遠端與人相當。 胃腸道環(huán)境的差異,如pH值、緩沖容量、滲透壓和表面張力,導致藥物溶解度的差異。 在兔子和豬中,美沙拉秦的溶解度在沿胃腸道向下移動(dòng)時(shí)發(fā)生顯著(zhù)變化,這在很大程度上受管腔液的pH值和滲透壓的影響。
