"„ , . large-scale production rate Scale-up ratio = — - n\ small-scale production rate Disperse system scale-up ratios may vary from 10 to 100 for laboratory to pilot-plant process translation and 10 to 200 for scaling from pilot-plant to commercial produc-tion. Actual production rates may vary considerably from expected production rates, since overall process efficiency is dependent on a wide range of factors. The process-ing of disperse systems, whether liquid-liquid or liquid-solid, is still relatively empiri-cal due to the substantial interfacial effects that predominate and control the relevant unit operations. Furthermore, unit operations may function in a rate-limiting manner as the scale of operation increases from the laboratory bench to the pilot plant to com-mercial production. Thus, although conventional wisdom suggests the necessity of scale-up studies, the appropriate approach is not necessarily initiated with miniaturized com-mercial processing systems [5]. The concept of scale-up has taken on a substantive regulatory aspect in more re-cent years with the issuance of Guidance 22-90 by the Food and Drug Administration's (FDA's) Office of Generic Drugs in September 1990 and the establishment of the Scale-Up and Post Approval Changes (SUPAC) Task Force by the FDA's Center for Drug Evaluation and Research. In May 1993, the American Association of Pharmaceutical Scientists, the Food and Drug Administration, and the United States Pharmacopeia cosponsored a workshop on the scale-up of liquid and semisolid disperse systems [6]. The primary finished product attribute to control during the scale-up of a disperse sys-tem, whether manufactured in identical, similar, or different equipment, is the degree of sameness of the finished product relative to previous lots. The consensus of the workshop committee was that four criteria be used to evaluate sameness: (1) adherence to raw material controls and specifications; (2) adherence to in-process controls; (3) adherence to finished product specifications; and (4) bioequivalence to previous lots. The aim of this chapter is to provide the formulator with an appreciation, on the one hand, of the complexity of the scale-up problem associated with disperse systems, and an awareness, on the other hand, that scale-up problems can be resolved, to a great extent, by drawing on the vast literature and experience of chemical engineering. In 1964, H. W. Fowler [7] initiated a series of progress reports in pharmaceutical engi-neering that appeared over time in the periodical Manufacturing Chemist. Fowler's ouevre was distinguished by his focus on fundamentals, i.e., on material properties and on operation and process mechanisms. His intention was "to look at the literature of chemical engineering and to discuss developments which are relevant to pharmacy." It is the present author's intention (in part, through this chapter on scale-up of disperse systems) to validate the interdisciplinary process that Fowler began more than 30 years."
