Mapping Advantages and Challenges in Analytical Development for Fixed Dose Combination Products, a Review.

Formulations containing more than one active ingredient are increasingly gaining popularity due to advantages with regard to patient convenience as well as reduced cost of production, packaging, and transportation. Such fixed-dose combinations (FDCs) demand for enhanced analytical methodologies and tools to efficiently achieve quality control of these complex products as compared to the conventional products containing only one active constituent. Highly efficient analytical methods can measure multiple constituents at once, improving their quality control.
