Drug information is actually a dying field in the profession. It's going nowhere and really doesn't have anything to offer for profit.
If you care about information and practice, might I interest you in opportunities in pharmacy informatics? Our job is to find ways of turning data into information for patients, other providers, and public heath. Current projects in the field range from creating a statewide immunization system, a portable electronic health record (imagine carrying around all of your health data on a chip), telemedicine/telepharmacy with the country from a metropolis, and smart deivices. It pays $39K for a fresh out-of-school Pharm. D.
It pays decently, and that's my Ph. D. major right now. I'm under the fellowship, but I don't practice unless it suits my interests.
