What forms of Naltrexone are avaliable in Europe?


Naltrexone is produced in several pharmacological forms.

Firstly, there is an oral Naltrexone in the form of pills or tablets.

Naltrexone tablets have been names differently depending on the country: for example in some countries it’s  Revia, or Naltrexone hydrochloride, in other countries Antaxon, Nalorex, Trixan, etc.

A standard dosage of Naltrexone pill is 50mg, which is more than enough to cover the opioid receptors in the period of 24h.

Besides, there is Naltrexone depot, so called implants or pellets, which are placed under the skin in the course of small surgical intervention by pushing the Naltrexone pellets out from a special syringe.

The inventor of one type of Naltrexone implants is an Australian doctor George O Niel who continues to refine his conception of Naltrexone blockers based on depot polymers. These implants are gradually dissolving in the body releasing the necessary dosages of Naltrexone.

Americans apply salts of fatty acids of Naltrexone. In most of the cases, Naltrexone binds to magnesium stearate. Dr. Lance Gooberman has developed this type of implants, which is mostly used in Europe.

Liquid forms of Naltrexone came out recently – Naltrexone injection. It is Naltrexone palmitate or Naltrexone in cotton oil. Intramuscular injection of Naltrexone cure provide blockade of opiate receptors for 1 month.

Scientist are trying to develop longer forms of Naltrexone depot, for example, Naltrexone implants for 24 months, which means that medication placed once will be able to provide reliable relapse protection for 2 years.
