title: [Ranking the efficacy of drugs--a question of "class"? It is difficult to determine equivalency of two different treatments].
abstract: Criteria for equivalence are essential when classifying drugs. Results from clinical trials remain the most practical way of defining "class". Class effect cannot be assumed, it must be proven, and one should not attempt to generalize results from one drug to another drug in the same class.
