What Defines an Ideal Film Coating Process?
Film coating is often considered to be a challenging step in tablet manufacturing. While the choice of film coating depends on factors like API’s characteristics, protective function, release profile of a drug and aesthetics of a tablet, its important to develop a coating process which is robust and provides uniform tablet coating.
The ideal film coating process is the one that brings efficiency in the coating process by being reproducible with same settings day after day. Along with that, to achieve excellent tablets in high yield, its important to set up the process in a way where the whole procedure can be completed with minimal adjustments to parameters.
Identifying right equipment and setting them up in appropriate way, is key in creating a robust coating process. Similarly, optimizing process parameters plays a huge role in designing an ideal film coating process. With slight adjustments to critical parameters, the formulators are able to not only decrease coating time but also to improve the overall tablet appearance and coating.
Uniformly coated tablets not only help in delivering a drug’s therapeutic value but it also aids in uplifting brand image and patient acceptance of a drug.
