NALTREXONE STABILITY IN AQUEOUS SOLUTION

NOT 1 day... NOT 1 week...BUT a MONTH or MORE!

Naltrexone is quite stable in water.

I am quoting from Trissel's book, "Stability of Compounded Formulations", Second Edition, page 266

"Stability-indicating HPLC analysis found less than 10% loss within 90 days at either 4 degrees C or 25 degrees C; most samples exhibited no loss. .... The recommended shelf lives of 30 and 60 days stored at 25 degrees C and 4 degrees C, respectively."

This is a reference book that every compounder OUGHT to have on hand.

4 degrees C is refrigeration and 25 degrees C is room temperature.

We make naltrexone solutions for people who need to adjust their doses. The most popular strength is 1mg per ml. We supply a syringe with which the patient can measure the correct dose. It is bitter so it needs to be mixed with something (unless you have strong taste buds). Nobody has ever complained that it "stopped working".
