Customer relationship management (CRM) involves shaping interactions between a company and its customers to maximize current and lifetime value. In pharmaceuticals, CRM is needed to understand customers better and improve channel management in a competitive market. While FMCG focuses on non-personal advertising, pharmaceutical CRM precisely tracks doctor prescription habits. Application in pharmaceuticals includes providing gifts, organizing conferences, distributing free samples and medicines, and conducting camps and continuing medical education. CRM practices involve timely calls, precision marketing, new sales strategies, and sales force management.
