Naltrexone is considered “standard dose” when given in daily amounts of 25mg or more and low dose when the daily dose is less than 25mg When prescribed in standard dose, Naltrexone acts primarily to block opiate receptors and as such is used mainly in addictions . When used in low dose, it is now widely understood to act as an Immunomodulator and multiple Phase I and II trials have shown efficacy.
