  The present invention relates to prodrugs of a wide variety of drugs and pharmaceutical compositions containing such prodrugs. Methods for minimizing locally mediated (from within the gut lumen) adverse gastrointestinal events associated with the underivatised drug and increasing the sustainment of plasma drug levels with the aforementioned prodrugs are also provided. Thus, the present invention relates to the use of prodrugs of a wide diversity of drugs (other than opioids) to transiently inactivate them and so reduce directly, locally mediated adverse gastrointestinal (GI) side-effects normally evident after administration of the parent compound. Additionally, such prodrugs may confer improved pharmacokinetics.

  本发明涉及各种药物的前药和含有这些前药的制药组合物。还提供了一种方法，用于最小化与未衍生药物相关的局部介导（来自肠腔内）不良胃肠事件，并使用上述前药增加血浆药物水平的持续性。因此，本发明涉及使用各种药物（除阿片类药物外）的前药，以短暂地使它们失活，从而减少通常在给予原始化合物后出现的直接、局部介导的不良胃肠（GI）副作用。此外，这些前药可能提供改善的药代动力学。
