Nalbuphine Hydrochloride is indicated for the relief of moderate to severe pain. It is used for relief of moderate to severe pain associated with myocardial infarction (MI). Nalbuphine Hydrochloride can also be used as a supplement to balanced anesthesia, for preoperative and postoperative analgesia, and for obstetrical analgesia during labor and delivery.


Nalbuphine Hydrochloride is a synthetic opioid analgesic, which binds with mu, kappa and delta receptor. Its analgesic potency is equivalent to Morphine on a milligram basis and 10 times more than that of Pentazocine but has lower side effects and less abuse potential than Morphine. The onset of action of Nalbuphine occurs within 2 to 3 minutes after intravenous administration and in less than 15 minutes following intramuscular injection. The plasma half-life of Nalbuphine is 5 hours and the duration of analgesic activity is 3 to 6 hours.
