Regarding to the appropriate drug delivery to patients, optimum performance of drug supply chain is very important for health care systems. Determining suitable supply chain performance needs indicators which can facilitate the assessment of supply chain activities in all steps and furthermore, these kinds of indicators improve effectiveness and efficiency of supply chain and drugs can distribute more sufficiently. The results of this research seem that the type of technology, information sharing, variety of products and the average of inventory can affect the performance of supply chain and furthermore, the drug supply chain performance is partly measureable and it can be used in comparing conditions and different states of drug supply chain ensuring that changes’ different states covers different variances contribute in outputs and inputs of drug supply chain and reflect them in achieved numbers.The purpose of this paper is to design a framework for defining key success factors which affect drug supply chain.So,firstly, dimensions of supply chain in pharmaceutical industry are surveyed and then, main indicators which are necessary to evaluate the performance of  drug supply chain are provided.
