Oversaturation measurements of SYA and INH were performed on the cocrystal in comparison to an equimolar blend of pure SYA and INH. The samples (cocrystal, blend of pure SYA and INH) were milled in mortars to avoid particle size effects. The dissolution rates of SYA and INH were measured in non-sink conditions using 300 g of substance in 500 mL of water at 37 °C and a paddle rotating at 10 rpm. At different intervals for 40 h, the samples were filtered through 0.45 µm nylon filter and assayed using high performance liquid chromatography
