Many pharmaceutical solids are able to adopt more than one crystalline form, and this property is called polymorphism. Currently 80-90% of the drugs are marketed as in solid forms and a very common problem is the low solubility of these drugs, particularly in aqueous media. Depending on how a drug crystallizes, its physical and chemical properties can be changed, which may also result in changes in its solubility. Before this problem the crystals engineering appears as a strategy to improve the properties of the solid state related to the efficacy of the drugs through the development of new crystalline forms. Multicomponent molecular crystals can be prepared from supramolecular synthons forming approach by crystallization methods involving ...
