摘要： Pharmaceutical solid dosage forms are covered with three successive layers of coating, consisting alternately of an undercoat composed substantially of a polymeric substance, a secondary coat composed substantially of a polymeric substance and a pigment, and a finish coat composed substantially of a polymeric substance. Application of these coatings produce economical advantages both in time and labor, and the surfaces of the coated dosage forms are smooth and glossy, and have no cracking.
