Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Meperidine is an opioid agonist that binds to mu-opioid receptors in the central nervous system, mimicking endogenous endorphins to produce analgesia, sedation, and euphoria. It also has additional weak actions at kappa and delta receptors.
LERITINE (anileridine) is a synthetic opioid analgesic that acts as a mu-opioid receptor agonist, modulating pain perception and emotional response to pain.
50-150 mg IM, IV, or SC every 3-4 hours as needed for pain; oral 50-150 mg every 3-4 hours.
Adults: 25-50 mg orally every 6 hours as needed for pain; not to exceed 200 mg/day.
