The approach to post-surgical pain relief has relied on short-duration treatments and notably opioids. That’s led to the associated risks of dependence and abuse, prolonged hospitalizations, and slower recoveries. Allay Therapeutics is developing an alternative to opioids to treat post-surgical pain with an initial focus on knee replacement surgeries. Allay’s guitar pick-sized polymer is implanted during surgical procedures and it releases the analgesic bupivacaine as it dissolves over 30 days. We spoke to Adam Gridley, CEO of Allay Therapeutics, about post-surgical pain, the need for alternatives to opioids; and the company’s implanted, extended-release analgesic.
