FASTER, PLEASE: A new approach to alleviating osteoarthritis pain. “A new class of pain relievers that targets musculoskeletal pain receptors, instead of more general pain pathways, could alleviate osteoarthritis pain better than any drug now on the market, but hurdles remain before the FDA approves it. . . . Tanezumab works by preventing a protein called nerve growth factor from attaching to sensory neurons, thereby stopping the neurons from transmitting pain signals to the brain. It’s a pathway specifically related to muscle and bone pain, and therefore provides an opportunity for targeted pain relief.”
