Abstract: Pharmaceutical cocrystals are a new solid form which can improve many physical and chemical properties of active pharmaceutical ingredients. As a potential new drug development technology, pharmaceutical cocrystals have many advantages over single component and compound drugs. In recent years, some pharmaceutical cocrystals have been approved for marketing, so a challenge to regulatory departments of drugs in China is to establish effective quality control methods for pharmaceutical cocrystals. Through the review of characterization methods of pharmaceutical cocrystals, we can find out more about the analytical techniques that can effectively identify pharmaceutical cocrystals so as to provide reference for the establishment of quality standards for pharmaceutical cocrystals.

Key words: cocrystal, characterization, XRD, TA, spectrometry, microscope, NMR, DVS
