Big pharmaceutical companies have found replacements for the army of sales representatives they’ve laid off in recent years: digital sales tools that seek to sell doctors on drugs without the intrusion of an office visit. Tens of thousands of pharmaceutical sales reps have been eliminated in the U.S., creating a void that drug makers are now increasingly filling with websites, iPad apps and other digital tools to interact with doctors who prescribe their treatments. Doctors can use the tools to ask questions about drugs, order free samples and find out which insurers cover certain treatments. Sometimes drug-company representatives will engage them in live chat, or phone them back if they have more questions.
