PEPAP

PEPAP (Phenethylphenylacetoxypiperidine) is an opioid analgesic that is an analog of pethidine (meperidine).

It is related to the drug MPPP, with an N-phenethyl group in place of the N-methyl substitution and an acetate ester rather than propionate. PEPAP is approximately 6-7 times more potent than morphine in laboratory rats. PEPAP presumably has similar effects to other opioids, producing analgesia, sedation and euphoria. Side effects can include itching, nausea and potentially serious respiratory depression which can be life-threatening.
