DESCRIPTION
Naltrexone Hydrochloride Tablets USP, an opioid antagonist, are a
synthetic congener of oxymorphone
with no opioid agonist properties. Naltrexone differs in structure
from oxymorphone in that the methyl
group on the nitrogen atom is replaced by a cyclopropylmethyl group.
Naltrexone Hydrochloride
Tablets USP are also related to the potent opioid antagonist,
naloxone, or n-allylnoroxymorphone. The
chemical name for naltrexone hydrochloride is Morphinan-6-one,
17-(cyclopropylmethyl)-4,5-epoxy-
3,14-dihydroxy-, hydrochloride, (5α)-.

CLINICAL PHARMACOLOGY
PHARMACODYNAMIC ACTIONS

hydrochloride blocks the physical
dependence to morphine, heroin and other opioids.
Naltrexone hydrochloride has few, if any, intrinsic actions besides
its opioid blocking properties.
However, it does produce some pupillary constriction, by an unknown
mechanism.
