Recent Patents of Pharmaceutical Co-Crystals: Product Development on Anti-Cancer Drugs and Beyond

Abstract

Background: Scientists, academicians, and researchers from academics and the pharmaceutical industries have all expressed interest in the design and production of pharmaceutical cocrystals in recent years. The development of novel drug products with enhanced physicochemical and pharmacological characteristics is aided by the cocrystallization of drug substances. Objective: The major problem with drug candidates is their solubility and bioavailability, which may be solved with the appropriate molecular modifications. The failure of most drug candidates in earlier clinical trials is also reawakening interest. In that connection, pharmaceutical cocrystals are vital in the development of dosage forms in the field of pharmaceutical technology. The goal of this manuscript is to provide a comprehensive overview of cocrystal synthesis methods and characterization techniques. Conclusion: In this review, it is evident that the solvent-free technique has several benefits over solvent-based approaches in the design and production of pharmaceutical cocrystals, and that these methodologies can also open opportunities for further advancement in the field of cocrystal synthesis. This manuscript provides a brief overview of each technique for manufacturing pharmaceutical cocrystals and an analysis of cocrystals. This manuscript has highlighted points on whether cocrystals comply with the requirements for intellectual property rights and how they will impact the current pharmaceutical industry. The impact of recent patents on pharmaceutical cocrystals is examined in depth with relevant examples.
