RT Journal A1 Friedrich MJ T1 REsearch yields new insights into mechanisms and treatment of pain JF JAMA JO JAMA YR 2012 FD January 18 VO 307 IS 3 SP 239 OP 241 DO 10.1001/jama.2011.1972 UL http://dx.doi.org/10.1001/jama.2011.1972 AB In neither type of pain is the pathogenesis completely understood, and a comprehensive picture of the mechanisms underlying these pain states, as well as the long-term consequences of injury, is needed to develop more effective pain therapies. While the drugs available to treat chronic pain are occasionally effective, rarely are they able to alleviate pain completely, said Allan Basbaum, PhD, of the University of California at San Francisco. “Inevitably, they stop working for reasons we don't understand, or the adverse side effect profile of the treatment makes it impossible for the patient to tolerate it,” he said.
