NRx Pharmaceuticals (NRXP) announced FDA approval for its preservative-free ketamine injection, ahead of the November 10 goal date. The product lacks benzethonium chloride, a toxic preservative in current ketamine injections. NRx aims to address the ketamine shortage and reshored manufacturing to the U.S. with Nephron Pharmaceuticals. The company will host a conference call on October 30 to discuss the approval.
