Formation of the first non-isostructural cocrystal of apremilast explained
Original language description
Search for new multicomponent solid forms has become a key step in pharmaceutical drug development. Apremilast, a poorly soluble API used for the treatment of psoriatic arthritis, was used as a model compound in this work. There have been several isostructural cocrystals of this API already described in the literature. In this paper, a new isostructural cocrystal (with phthalic acid) and solvates (with o-xylene and fluorobenzene) of the studied compound were successfully designed. Furthermore, to the best of our knowledge, this work is the first ever to prepare a non-isostructural cocrystal of apremilast with cinnamic acid. The crystal structures of all the new multicomponent forms were successfully solved using single crystal X-ray diffraction. The differences between the formation of the isostructural and non-isostructural forms are explained in detail using the structural characterization of the prepared forms and the density functional theory calculations (B3LYP/6-31G(d,p) level of theory). The physicochemical characterization complemented the structural one, including the thermal properties (differential scanning calorimetry, DSC) and the intrinsic dissolution rate (IDR). The samples were further characterized by X-ray powder diffraction (XRPD) and Raman spectroscopy. The dissolution experiments showed that the new multicomponent solids can improve the intrinsic dissolution rate by up to 500% compared to the polymorph of apremilast used in the marketed drug product.
