What is dipyanone?

Dipyanone is a synthetic opioid analgesic drug that has sedative and antitussive properties. It was first synthesized in the 1950s by Janssen Pharmaceutica and was intended for use in clinical anesthesia. However, dipyanone never gained widespread use in medicine due to its high potential for dependency and abuse.

Dipyanone is structurally similar to methadone and fentanyl, but it is not as potent as these drugs. It is typically administered orally or intravenously and has a relatively short half-life of about 4 hours. The effects of dipyanone can include pain relief, euphoria, drowsiness, and respiratory depression.

The use of dipyanone is highly regulated in many countries, and it is classified as a controlled substance under international law. In some regions, it is illegal to produce, sell, or possess dipyanone without a prescription. Due to its high risk of addiction and overdose, dipyanone is not recommended for long-term use or for individuals with a history of substance abuse.
