The present disclosure relates to a cocrystal of telmisartan and hydrochlorothiazide, a preparation method and use thereof. In the cocrystal, the molar ratio of telmisartan and hydrochlorothiazide is 1:1. The cocrystal of telmisartan and hydrochlorothiazide was characterized by X-ray powder diffraction (XRPD), proton nuclear magnetic resonance spectra (1H-NMR), thermal gravimetric analysis (TG), scanning differential calorimetry (DSC) and infrared (IR) spectra, and it was found that the maximum plasma concentration of the cocrystal in SD rats was higher than that of any one of hydrochlorothiazide and telmisartan itself. The cocrystal of telmisartan and hydrochlorothiazide has a simple preparation method and good physical and chemical properties.

A method of making a water-soluble doxorubicin-theanine cocrystal composition. The method includes the steps of providing a quantity of doxorubicin, adding a quantity of a theanine enantiomer to the quantity of doxorubicin to form a mixture of the quantity of doxorubicin and the enantiomer of theanine, wetting the mixture, and grinding the mixture for a length of time sufficient to produce a dried crystalline mass.

A method of treating Hodgkin's disease in a subject. The method involves administering to the subject an effective amount of a water-soluble composition which includes a cocrystal composition containing doxorubicin and a theanine enantiomer.
