Evaluation of Drug Efficacy by a Preference Technic

Abstract

INCREASED awareness of the importance of properly controlled drug evaluations has brought with it a need for the development of experimental technics that can provide essential information about drug effects. Since an enormous number of drugs are available for therapeutic use, and the relative efficacy of most has not been fully evaluated, an important element to consider in designing such studies is simplicity. Studies that involve the accumulation of large quantities of data obtained at frequent intervals require numerous personnel. Furthermore, since a large proportion of their time is spent in the frequent collection of information, relatively few studies can . . .
