Preformulation is a set of studies that examine the physicochemical features of a novel drug candidate and how they might affect medication performance and dosage form creation. This could be useful for formulating new products or demonstrating the necessity for molecular change. Once the novel molecule has been seeded, the preformulation investigation begins. In a broader sense, it concerns examinations of a molecule's physical, chemical, analytical, and pharmaceutical properties, as well as suggestions for modifying the molecule to improve its performance. As a result, a preformulation study is a method for developing pharmaceutical formulations that incorporates toxicology, biochemistry, medicinal chemistry, and analytical chemistry knowledge and application.
