One of the unique characteristics of pharmaceutical market is that ultimate consumer
is not the decision-maker in choosing which drug to purchase (Kim and King, 2009).
Furthermore, pharmaceutical marketing is a multi-customer/multi-touch system which
makes it difficult to prioritize and target the customer (Dadfar et al., 2012). For example,
physicians decide upon and prescribe the drugs; distributors/wholesalers buy drugs
from manufacturers/importers; retail pharmacies purchase drugs from distributors;
the end-users buy the prescribed drugs from the pharmacies, and usually the insurance
companies pay the drug cost. The authors identified three core-customers and the end –
customer who pharmaceutical marketers must influence
