ABSTRACT OBJECTIVE To prepare progesterone-2-chloro-4-nitroaniline cocrystal (CNA) so as to improve the solubility of
progesterone and primarily evaluate the safety of the progesterone cocrystal in vivo. METHODS Using progesterone as the main
body and CNA as the ligand, progesterone-CNA cocrystal was prepared with solvent evaporation method. The cocrystal was
characterized by X-ray single crystal diffraction, X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC) and
Fourier transform infrared spectroscopy (IR). The dissolution rate of cocrystal was compared with those of progesterone and
physical mixture. Forty-eight female KM mice were randomly divided into normal group (phosphate buffer containing 0.1%
dimethyl sulfoxide), progesterone group (16 mg/kg), CNA group (9 mg/kg), progesterone-CNA cocrystal low-dose, medium-
dose and high-dose groups (6, 12.5, 25 mg/kg), with 8 mice in each group. They were given relevant medicine/solvent
intramuscularly, once a day, for consecutive 14 d. The safety of cocrystal was evaluated primarily by determining/observing the
changes in body weight, organ index, tissue morphology, blood routine indicators, and liver and kidney function indicators.
RESULTS The new crystal structure in the X-ray single crystal diffraction results, the new characteristic peak in the XRPD
pattern, the change of melting point in the DSC results, and the change of the characteristic peak position in the range of 3 500-
2 750 cm and 1 700-1 250 cm in the infrared spectrum all
