WebMar 28, 2024 · Co-crystals and salts are two common forms of multicomponent crystals which might have higher solubility and faster dissolution behavior compared to untreated drugs [4,5]. Compared to cocrystals, salt formation is the simplest and most cost-effective strategy and has significant advantages in addressing poor aqueous solubility because … The crystallization process consists of two major events, nucleation and crystal growth which are driven by thermodynamic properties as well as chemical properties. Nucleation is the step where the solute molecules or atoms dispersed in the solvent start to gather into clusters, on the microscopic scale (elevating solute concentration in a small region), that become stable under the current operating conditions. These stable clusters constitute the nuclei. Therefore, the clusters … crypto spike today
