L-ORNIDAZOLE FORMULATIONS AND THEIR APPLICATIONS IN TREATMENT OF PARASITIC INFECTIONS

摘要

This invention relates to new methods of treating parasitic infections, such as trichomonas vaginalis infection and cecum amoeba infection, using L-enantiomer enriched ornidazole, in particular enantiomerically pure L-ornidazole, which provides benefits such as higher efficacy and lower toxicity to central nervous system over the existing racemic Ornidazole drug. New methods of synthesizing L- and D-enantiomers of Ornidazole in high purity and enantiomeric excess (ee), new formulations of the enantiomerically enriched L- or D-ornidazole, as well as their preparation processes and methods of use, are also disclosed.
