5 Pharmacology and Biochemistry
5.1 Mechanism of Action

PTI-801 is a novel form of oxycodone that minimizes the abuse and drug dependence that is often associated with oxycodone and other narcotic painkillers. The goal of developing PTI-801 is to ensure the safety of patients who have a legitimate medical need to treat severe chronic pain with a narcotic painkiller, and to protect the public from the consequences of abuse.
