“…The yield was further augmented by introducing cooling into the system: the timing of the cooling influenced the formation of the cocrystals. The metastable α-indomethacin formed only when the cooling was applied before the nucleation [124].…”

The use of drug nanocrystals in the drug formulation is increasing due to the large number of poorly water-soluble drug compounds synthetized and due to the advantages brought by the nanonization process. The downsizing processes are done using a top-down approach (milling and homogenization currently employed at the industrial level), while the crystallization process is performed by bottom-up techniques (e.g., antisolvent precipitation, use of supercritical fluids or spray and freeze drying). In addition, the production of nanocrystals in confined environment can be achieved within microfluidics channels. This review analyzes the processes for the preparation of nanocrystals and co-crystals, divided by top-down and bottom-up approaches, together with their combinations. The combination of both strategies merges the favorable features of each process and avoids the disadvantages of single processes. Overall, the applicability of drug nanocrystals is highlighted by the widespread research on the production processes at the engineering, pharmaceutical, and nanotechnology level.

“…A suitable type of solvent is used in solution method for the preparation of cocrystals. Different types of solution methods such as solvent evaporation [76] , solution crystallization technique [41] , antisolvent addition [82] , slurry conversion method [83] and reaction crystallization method [84] are discussed with suitable examples. Grinding methods are of two types: neat grinding and solvent drop grinding [85,86] .…”

The active moiety with poor solubility is posing a challenge in drug development which may reduce the effectiveness in patients when administered orally. Cocrystal formation is one of the latest approaches for improving the various parameters of a drug molecule such as solubility, melting point, pharmacokinetic, pharmacodynamic, and bioavailability. Cocrystals are crystalline single state materials composed of two or more than two different molecular amalgams held together in a fixed stoichiometric ratio. There are various techniques used for the preparation of cocrystals such as solvent evaporation, grinding, and cooling crystallization. The quantitative and qualitative aspects of these cocrystals are evaluated using various validated instruments such as nuclear magnetic resonance, powder X-ray diffraction, and differential scanning calorimetry.
