Abstract: Objective Only prepared as a certain dosage form, drug could be applied to prevention, diagnosis and treatment. With the development of modern medicine, the relationship of pharmaceutics and organ system has become increasingly clear. Modern pharmaceutical teaching should be on an open way to develop. Methods Through the discussion on pharmaceutical theoretical teaching based on the industrial preparation and the organ system, this article expounded a new thinking and idea about pharmaceutical teaching of undergraduates. Results As a subject of application, pharmaceutical teaching should explore the theoretical teaching model which makes the organ system as a basis and takes the disease as a core. Conclusion The course on the basis of the organ system should be divided and integrated, connected with clinical practice, the course content should be optimized and the different dosage forms should be compared according to the organ system as a main line. Such a new exploration will offer more help to the students to understand and design dosage form from the perspective of clinical need
