Oripavine is an opioid and the major metabolite of thebaine. It is the precursor to the semi-synthetic compounds etorphine and buprenorphine. Although this chemical compound has analgesic potency comparable to morphine, it is not used clinically due to severe adverse effects and a low therapeutic index. Being a precursor to a series of extremely strong opioids, oripavine is a controlled substance in some jurisdictions.

== Pharmacological properties == Oripavine possesses an analgesic potency comparable to morphine; however, it is not clinically useful due to severe toxicity and low therapeutic index. In both mice and rats, toxic doses caused tonic-clonic seizures followed by death, similar to thebaine. Oripavine has a potential for dependence which is significantly greater than that of thebaine but slightly less than that of morphine.
