The present invention provides accelerated detoxification methods for the treatment of a substance abuse-related condition in a subject. A method of the present invention may comprise administering to the subject an effective amount of at least one sedative (e.g, clonidine, diazepam, or olanzapine) and a micro-dose of an opioid antagonist (e.g., naltrexone or naloxone) for at least one day; optionally administering a small dose of an opiate, and administering to the subject a detoxifying amount of a second opioid antagonist (e.g., naloxone); and may further comprise administering to the subject a third opioid antagonist (such as, naltrexone) for an extended period of time (e.g., 12 months).

The invention provides an opiates painkiller and opiate receptor antagonist-containing medicinal composition. In the medicinal composition, an opiates painkiller is fentanyl, remifentanil, sufentanil, alfentanil and pharmaceutically acceptable salts thereof; and an opiate receptor antagonist is naloxone, naltrexone, nalmefene and pharmaceutically acceptable salts thereof. The medicinal composition has a pharmacological effect on analgesia. Compared with using the opiates painkiller singly, the composition can prevent and/or lighten side effects in pain treatment, reduce abuse and improve adaptability, and has a reinforcing effect on an analgesic effect of the opiates painkiller.

The invention relates to a naloxone hydrochloride freeze-dried powder injection and a preparation method thereof. The naloxone hydrochloride freeze-dried powder injection in every 1000 bottles is obtained by adding water for injection to dissolve the following ingredients and then freeze-drying: 0.1-5g of naloxone hydrochloride, 30-60g of mannitol and 0.01-0.5g of edetate disodium; before the freeze-drying, the pH value of the solution is 2.0 to 5.0. According to the invention, through controlling different pH value regulation ranges during the preparation process of different specifications of the naloxone hydrochloride for injection, the finished products can meet the prescribed standards after the freeze-drying, so that the quality and the stability of the product are improved.
