A Review on Co-Crystallization: A Novel Technique for Enhancement of Solubility and Bioavailability

Drugs' poor oral bioavailability and poor
solubility are the main issues throughout the design and
development of new products. Although they have
significant drawbacks, traditional approaches have been
used to increase the solubility of medications that are
weakly soluble in water, such as solvates, salts, and
polymorphs. The co-crystallization strategy is utilised as
an alternate method to modify the physicochemical
properties of an active pharmaceutical ingredient without
changing its pharmacological action, such as solubility,
bioavailability, permeability, flowability, and melting

point. Drug and co-former are both included in co-
crystals, which are multi-component crystalline systems

with the same crystal lattice. A comprehensive overview
of pharmaceutical co-crystals is provided in this review

article. This page provides a summary of the benefits, co-
crystal formation processes, evaluation, and

characterisation testing.
