Naltrexone is a medication primarily used to manage alcohol or opioid dependence. An opioid-dependent person should not receive naltrexone before detoxification. It is taken by mouth or by injection into a muscle. Effects begin within 30 minutes. A decreased desire for opioids, though, may take a few weeks.

Application&Function

Naloxone hydrochloride occurs as a white to slightly off-white powder, and is soluble in water, in dilute acids, and in strong alkali; slightly soluble in alcohol; practically insoluble in ether.
Naloxone hydrochloride injection is available as a sterile solution for intravenous, intramuscular, and subcutaneous administration. Each mL contains 0.4 mg of Naloxone hydrochloride. Each mL contains 8.9 mg of sodium chloride. The pH is adjusted between 3.0 to 6.5. The air in the cartridges has been displaced by.
The most common side effects reported with naltrexone are gastrointestinal complaints such as diarrhea and abdominal cramping.
These adverse effects are analogous to the symptoms of withdrawal, as the mu receptor blockade will increase GI motility.
