This document discusses pharmaceutical marketing. It begins by defining marketing and noting that while pharmaceutical marketing is similar to general marketing, consumers have little choice in drug selection as decisions are made by physicians. Pharmaceutical marketing, also called medico-marketing, involves advertising and promoting drug sales. Several countries regulate drug advertising. The document then outlines key functions of marketing including buying, selling, transportation, storage, financing, risk-taking, and collecting marketing information. It discusses how physicians are the decision-makers in drug selection and how pharmaceutical companies aim to influence them through advertising, sales representatives, and promotional materials. Different modes of drug transportation and storage requirements are also summarized.
