<unk>  is generally administered intravenously (as Dalgan) to relieve post-operative pain in patients. It can also be administered in intramuscular doses, and is given once rather than continuously. It is often administered in post-operative laparoscopy patients as an alternative to fentanyl.<unk>  has potent analgesic effects, and comparable or greater pain-relieving ability than morphine, codeine, and pethidine (meperidine). It is a more effective analgesic than pentazocine, but causes relatively more respiratory depression than pentazocine.<unk>  is a useful drug for the treatment of pain, but side effects such as dizziness limit its clinical application, and it can produce opioid withdrawal syndrome in patients already dependent on other opioids. Because of its high efficacy,<unk>  is often administered at a base dose of 0.1 mg/kg. Respiratory depression, a side effect of<unk> , reaches a ceiling at 0.3 to 0.4 mg/kg.
