Several pharmaceutical companies are currently developing bi- layer tablets for a variety of reasons like patent extension, therapeutic efficacy, marketing etc. This technology has been used to reduce capital investment. Modified tablet presses have been used to develop bilayer tablets in order to overcome problems associated with tablets like layer separation, insufficient hardness, inaccurate individual layer weight control, cross contamination between the layers, reduce yield etc. When high production output is required a modified tablet, press is used.
