    摘要: The present invention concerns prodrugs of mexiletine (and mexiletine's active metabolite) with amino acids or peptides and pharmaceutical compositions containing such prodrugs. Methods for providing pain relief, treating arrhythmia, decreasing the adverse GI side effects associated with mexiletine, increasing the bioavailability of mexiletine, and improving the pharmacokinetic reproducibility of mexiletine with the aforementioned prodrugs are also provided. Oligopeptides incorporating lysine or arginine residues attached directly or indirectly through a glycine residue are also described herein.

    摘要: The present invention relates to a class of compounds and to diagnostic compositions containing such compounds where the compounds are iodine containing compounds. More specifically the iodine containing compounds are chemical compounds containing two linked iodinated phenyl groups of the general formula R-N(CO-CH2R1) -X-N(CO-CH2R1 )-R and salts or optical active isomers thereof, wherein each R1 independently denotes a hydrogen or a C1 to C4 alkoxy moiety provided that at least one R1 denotes a C1 to C4 alkoxy moiety; X denotes a C3 to C10 straight or branched alkylene moiety which may be further substituted, and each R denotes a triiodinated phenyl residue further substituted by hydrophilic moieties. The invention also relates to the use of such compounds and diagnostic compositions as contrast agents in diagnostic imaging and in particular in X-ray imaging.
