Reverse Engineering for Formulations

        Reverse engineering research serves as a core technical approach throughout the entire development lifecycle of innovative drugs and generic drugs, with its importance and necessity closely associated with regulatory requirements.

        • Due to the structural complexity, specialized manufacturing processes, and stringent quality control requirements, complex injectable products present significant challenges in formulation development. Key technical challenges include maintaining colloidal structure stability, ensuring strict sterility control, achieving scalable manufacturing processes, controlling particulate matter, and establishing in vitro–in vivo consistency. These challenges are common in both generic and innovative formulation development.

        • For non-sterile oral dosage forms, formulation structures are highly diverse, drug release mechanisms are complex, and in vivo influencing factors are variable. Major development challenges include limited dissolution of poor soluble drugs, inadequate crystalline form and solid-state stability, susceptibility of modified-release behavior to gastrointestinal conditions, difficulties in establishing in vitro–in vivo correlation, and significant batch-to-batch variability caused by multiple formulation and process parameters. These technical barriers are encountered in both innovative drug development and applications for generic drug equivalence evaluations.

        Bostal’s Reverse Characterization Engineering Platform for Pharmaceutical Formulations strictly follows regulatory requirements and focuses on lifecycle quality control and development needs of pharmaceutical products. Based on the structural characteristics, sterility requirements, and quality challenges associated with different dosage forms, the platform has established a comprehensive, multidimensional, and regulatory-compliant reverse characterization technology system. The platform integrates a broad range of analytical approaches, including chromatographic analysis, spectroscopic analysis, microscopic morphological characterization, thermal analysis, sterility testing, and process simulation. Through comprehensive analytical capabilities and precise characterization technologies, the platform addresses critical technical challenges encountered during formulation development, manufacturing, and quality verification. It ensures compliance with regulatory standards and supports product safety. By applying reverse characterization technologies, the platform provides scientific support for generic drug equivalence evaluation, quality replication of reference listed drug, and manufacturing process optimization. These capabilities help pharmaceutical companies improve product quality, mitigate regulatory risks, and accelerate product development and market approval.
