ABSTRACT
Aqueous coating technology remains the main option for film coating of oral solid dosage forms. This is irrespective of the purpose of the film-coating applications, i.e. for conventional and modified-release film coatings. The main reasons for its continued popularity are the environmental limitations of organic solvents used, recent advances in the formulation of aqueous film-coating materials, as well as major improvements made in the coating machines and their ancillaries.
