商品名：Torbutrol and Torbugesic
Opioid analgesic. Opiate that acts as kappa receptor agonist and weak mu-receptor antagonist (some authorities classify the antagonist effect as a “partial agonist” effect). As a kappa-agonist, butorphanol produces sedation and analgesia in animals. It is considered a mild analgesic compared to pure mu-receptor opiates. It is often used in combination with other anesthetics. It has a short half-life in animals (1-2 hours) and a short duration of analgesia (1-2 hours). 90 Butorphanol Tartrate
Busulfan is used primarily for lymphoreticular neoplasia.
