ConclusionsThese data suggest that low-efficacy opioids possessing significant mu-agonist activity (e.g. buprenorphine, butorphanol, nalbuphine, (−)-pentazocine ) may potentiate the effects of cocaine in a manner similar to that typically observed with high-efficacy mu opioids.
The high-efficacy mu opioid levorphanol, and the low-efficacy opioids buprenorphine, butorphanol, nalbuphine and (−)-pentazocine , dose-dependently enhanced the effects of cocaine at doses that did not alter locomotor activity when administered alone.

In myenteric plexus-longitudinal muscle preparations of isolated guinea pig ileum, 1 microM cocaine enhanced the agonistic effects of both pentazocine and ethylketocyclazocine.
These results indicate that cocaine may potentiate the antinociceptive effects of morphine and pentazocine by acting on the kappa-opioid receptors as an agonist.
