The invention provides a method of sustained delivery of a lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug by administering to a patient an effective amount of a prodrug compound of the invention wherein upon administration to the patient, release of the parent drug from the prodrug is sustained release. Prodrug compounds suitable for use in the methods of the invention are labile conjugates of parent drugs that are derivatized through carbonyl linked prodrug moieties. The prodrug compounds of the invention can be used to treat any condition for which the lactam, imide, amide, sulfonamide, carbamate or urea containing parent drug is useful as a treatment.
本发明提供了一种持续释放内酰胺、亚酰胺、酰胺、磺酰胺、氨基甲酸酯或尿素含量原药的方法,通过向患者施用本发明的前药化合物的有效量,在患者体内,从前药中释放出原药的持续释放。适用于本发明方法的前药化合物是通过羰基连接的前药基团衍生化的,是前药原药的不稳定结合物。本发明的前药化合物可用于治疗任何需要使用内酰胺、亚酰胺、酰胺、磺酰胺、氨基甲酸酯或尿素含量原药作为治疗的情况。
