Stange, PhD, Professor of family medicine and community health at Case Western Reserve University, states, "Consumer advertising, delivered to the masses as a shotgun blast, rather than as specific information to concerned patients or caregivers [from healthcare professionals], results in more prescriptions and less appropriate prescribing.” [ 53 ]
