DESCRIPTION
Naltrexone hydrochloride, an opioid antagonist, is 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 is also related to the potent opioid
antagonist, naloxone, or n-
allylnoroxymorphone.
naltrexone hydrochloride
Naltrexone hydrochloride is a white, crystalline compound. The
hydrochloride salt is
soluble in water to the extent of about 100 mg/mL. Naltrexone
Hydrochloride Tablets
USP are available as film coated tablets, containing 50 mg of
naltrexone hydrochloride.
Naltrexone hydrochloride tablets also contain: crospovidone,
hydroxypropyl
methylcellulose, lactose monohydrate, magnesium stearate,
microcrystalline cellulose,
polyethylene glycol, polysorbate 80, silicon dioxide, titanium
dioxide, yellow iron oxide
and red iron oxide.
CLINICAL PHARMACOLOGY
PHARMACODYNAMIC ACTIONS
Naltrexone is a pure opioid antagonist. It markedly attenuates or
completely blocks,
reversibly, the subjective effects of intravenously administered
opioids.
When coadministered with morphine, on a chronic basis, naltrexone
blocks the physical
dependence to morphine, heroin and other opioids.
Naltrexone has few, if any, intrinsic actions besides its opioid
blocking properties.
However, it does produce some pupillary constriction, by an unknown
mechanism.
The administration of naltrexone is not associated with the
development of tolerance or
dependence. In subjects physically dependent on opioids, naltrexone
will precipitate
withdrawal symptomatology.
Clinical studies indicate that 50 mg of naltrexone hydrochloride will
block the
pharmacologic effects of 25 mg of intravenously administered heroin
for periods as long
as 24 hours. Other data suggest that doubling the dose of naltrexone
hydrochl
