This review evaluates cocrystal screening methods to accelerate the development of fixed-dose combinations (FDCs). It guides researchers in selecting appropriate techniques for identifying drug-drug cocrystals (DDCs) and optimizing FDC formulations.
Area of Science:
- Pharmaceutical Sciences
- Materials Science
- Drug Development
Background:
- Fixed-dose combinations (FDCs) offer benefits like improved drug delivery and extended patent life.
- Drug-drug cocrystals (DDCs) represent a promising FDC strategy, but their development is hindered by a lack of standardized screening methods.
- Identifying cocrystal formation potential between co-administered active pharmaceutical ingredients (APIs) is crucial for successful FDC formulation.
Purpose of the Study:
- To review and evaluate existing methods for cocrystal and DDC screening.
- To provide a guide for selecting suitable screening strategies to accelerate FDC and DDC development.
- To address the limitations impacting the commercialization of DDCs.
Main Methods:
- Literature review of experimental cocrystal screening techniques.
- Evaluation of knowledge-based approaches for cocrystal prediction.
- Analysis of computational methods for cocrystal screening.
- Discussion of the background, application, and limitations of each screening category.
Main Results:
- Existing screening methods for cocrystals and DDCs vary in their applicability and limitations.
- A comprehensive evaluation of experimental, knowledge-based, and computational methods is presented.
- The review highlights the need for coherent strategies to facilitate DDC commercialization.
Conclusions:
- Selecting appropriate cocrystal screening methods is essential for accelerating FDC development.
- This review serves as a valuable resource for researchers aiming to optimize FDC and DDC formulation strategies.
- Standardized and efficient screening approaches will drive the successful commercialization of DDCs.
