Pharmaceutical co-crystallization is one of the approaches to enhance the solubility and other physicochemical properties
of poorly soluble drugs. Co-crystallization is a pure crystal engineering technique and has been most widely exploited
in the past decade. The technique gained popularity because crystalline state is the most preferable form of API on account
of its inherent low energy and thermodynamic stability. Nicotinamide or niacinamide is an amide of niacin. It is not only
safe and extensively used in man but is also considered the most suitable coformer for cocrystallization when solubility and
dissolution enhancement is desired, owing to its hydrophilic nature. The objective of our work was to improve the solubility
and dissolution properties of a model BCS-Class-II drug by formulating nicotinamide co-crystal. We evaluated the effect
of cocrystallization on the drug solubility and dissolution anticipating a bioavailability enhancement in our future studies.
The present study covered preformulation, formulation and in-vitro characterization stages of the prepared formulation. The
preformulation phase included UV, FTIR and solubility studies. The nicotinamide cocrystals were prepared by coevaporation
method and characterized for solubility and dissolution properties. The results indicated improvement in the solubility
and dissolution characteristics of the drug when formulated as nicotinamide cocrystal. The promising batches were further
subjected to thermal analysis and crystallographic studies to understand the solid state characteristics.
