Abstract
Multitoned compressed tablet forms of pleasing and distinctive appearance are obtained in a single granulation and coloring step by treating an excipient mixture of microcrystalline cellulose and modified corn starch containing a therapeutically effective quantity of an active drug or drugs with a granulating solution containing a water soluble dye suitable for pharmaceutical application. Work-up of the wetted granulation by usual wet granulation techniques followed by compression of the finished granules results in a distinctive multitoned tablet form.
