Minnesota doctors were paid thousands of dollars in speaker fees and other payments in 2008 by a pharmaceutical company now implicated in a congressional investigation for its aggressive promotion of a popular antidepression drug, according to documents filed with the state and analyzed by a nonprofit group. Forest Laboratories Inc. paid 62 Minnesota doctors at least $1,000 each in speakers' fees, with 28 physicians receiving payments of more than $10,000, according to The Pew Prescription Project.
