商品名：Talwin-V
Synthetic opiate analgesic. The action of pentazocine results from its effect as a mu-opiate receptor partial agonist and a kappa-receptor agonist. Most of the sedative and analgesic effects are believed to be caused by the kappa-receptor effects. Pentazocine may partially reverse some mu-receptor agonist effects. Its effects are believed to be similar to buprenorphine or butorphanol, but efficacy is less.
Pentazocine has been used for sedation and analgesia, primarily in horses. However because of the availability of other opioids with better efficacy, the use of pentazocine has declined.
