S-ornidazole compound and medicament composition thereof

The invention discloses an S-ornidazole crystal compound which is represented by an X-ray powder diffraction picture 1 measaured by Cu-Ka1 ray and a capsule containing the S-ornidazole crystal compound. A filler in the capsule comprises powder and particles; the powder comprises S-ornidazole crystals, a solubilizer and a lubricating agent; the particles comprises S-ornidazole crystals, a filling agent, a disintegrating agent and an adhesive. Medicament auxiliaries used for the S-ornidazole capsule nearly do not have a side effect on a human body; an in-vitro experiment shows that the biological utilization rate is increased.
