“…For new products, physicians require substantial information about the efficacy and safety profile of the drug, various clinical trials done for the molecule, the approvals given by the relevant authorities and additional benefits as compared to established brands (Mizik and Jacobson, 2004;Narayanan and Manchanda, 2009;Faisal et al, 2020;Morgan and Zane, 2022). Since PSRs are the ones who introduce new products to physicians, the onus of explaining newly launched products and providing required information for reducing uncertainty about newly launched drugs lies with PSR (Narayanan and Manchanda, 2009;Alkhateeb et al, 2011;Faisal et al, 2020;Vandenplas et al, 2022). Avorn et al, 1982 have observed that scientific information is a major source of influence on physician's prescription behaviour, more so for new drugs (McGettigan et al, 2001;Narayanan and Manchanda, 2009;Faisal et al, 2020) as compared to established brands.…”
