Naltrexone  is a strong and highly specific opiate antagonist.

Naltrexone binds to opiate receptors and prevents from penetration of heroin, methodon, codeine, dentoxile and other opiates thereto. Owing to this effect opiates administrated in the body do not produce their specific effect (euphoria, miotic pupils etc.).

Thus, patient taking Naltrexone in doses prescribed by doctor cannot have narcotic intoxication if takes heroin or other opiates in.   

Usual administration regime of Naltrexone is 1 tablet (50 mg) 1 times a day. Other administration regimes are also possible: 2 tables every other day or 3 tablets one time every third days.

Clinical studies prove safe administration of Naltrexone in the above-mentioned doses. Naltrexone does not provoke dependence or any addiction.
