Similarity to known substances and effects on the CNS
PEPAP has- been classified pharmacologically as an agonist of mu-type opioid receptors with a profile similar to-that of pethidine. It possesses analgesic activity and produces morphine-like euphoric effects. Its analgesic potency is about twice that of morphine.

can be reversed by narcotic antagonists such as naloxone.

Dependence potential
PEPAP substitutes completely for morphine i m morphine: dependent monkeys.

Actual abuse and or/evidence of likelihood of abuse
Seizure of a clandestine laboratory. and confiscation of numerous street samples containing PEPAP have been reported by the USA. PEPAP is controlled asa narcotic substance in France and the USA.

Therapeutic usefulness
At present, PEPAP has no Known therapeutic use.

Recommendation
The Committee found that there was sufficient evidence to indicate that PEPAP is liable to similar abuse as, and produces ill effects similar to those seen with, drugs in Schedule I of the Single Convention on Narcotic Drugs, 1961 and that Convention as amended by the 1972 Protocol. The Committee rated the abuse liability of the.drug as high. The degree of seriousness

of the public health and social problems associated with the drug was found to be high, and there is no known therapeutic use. Therefore, the Committee recommended that PEPAP be

controlled in Schedules I and IV of the Single Convention on Narcotic Drugs, 1961 and that Convention. as amended by the 1972 Protocol.
