Pentazocine (Talwin) originally was believed to be a safe, nonaddictive analgesic, but further experience has shown that severe mental and emotional disturbance, as well as addiction, may occur. This survey documents the experience in the Texas Medical Center and elsewhere. The accumulated data show the following: (1) Depressive states are reported most frequently, while toxic psychoses, hallucinogenic reactions with panic, and paranoid states on withdrawal of the drug are less frequent. (2) Of the 197 cases of addiction reported to date, only six were related to oral use of the drug. The abstinence syndrome is mild, consisting usually of restlessness, nausea, cramps, and insomnia. (3) Convulsions have been reported on four occasions. Euphoria and psychotomimetic effects may relate to rapid release of noradrenaline and dopamine. Oral use of the drug is advised to avoid euphoriant effects and addiction, and physicians should alert patients to report unusual visual phenomena. Tranquilizers are of value in cases of severe reactions.

Piper longum root, commonly called Kandantippili, is traditionally used to treat rheumatism, insomnia, palsy and epilepsy. But a scientific study on its central actions is not available. This study screens P. longum root for opioid type analgesia using rat tail-flick method and for NSAID type analgesia using acetic-acid writhing method. Pentazocine (ip) and ibuprofen (oral) are used as respective drug controls. An aqueous suspension of P. longum root powder is given orally to mice and rat in doses of 200, 400 and 800 mg/kg. The delay in reaction time for thermal stimulus in rats and the number of writhings to chemical stimulus in mice are determined in each group. The results are analysed statistically. The 400 and 800 mg/kg doses of P. longum show significant NSAID type of analgesia (P < 0.001). Both Ibuprofen (40 mg/kg) and P. longum (800 mg/kg) show 50% protection against writhing. The delay in reaction time to thermal stimulus was less than 6% for different doses of P. longum as against 100% for pentazocine. This indicates that P. longum root has weak opioid but potent NSAID type of analgesic activity.
