Scientific research-based evidence used in drug promotion material distributed in Sri Lanka

Abstract

In the drug promotion process, pharmaceutical companies make many claims about the efficacy, safety and ‘quality’ of the products. These claims should be clear, valid and justifiable. In scientific literature, each claim should be supported by evidence. Therefore, they are expected to provide evidence to support the claims made in DPM. The high quality references increase the authenti-city of the evidence. The aim of this study was to examine the quality of scientific supportive evidence used in DPM in Sri Lanka.
