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.
