Amfonelic acid (AFA; WIN 25,978; Oxaprozin) is a psychoactive drug and research chemical used in scientific studies. It was discovered while researchers were investigating novel antibiotics.^[1] It acts as a potent and highly selective dopamine reuptake inhibitor (DRI).^[2]^[3] It has a moderately long half-life of approximately 12 hours. It is currently being researched as a medication to offset the sedative side-effects and enhance the noiciceptive activity of strong opioid analgesics^[4]
