Naltrexone johnson north a comparatively new medication used in drug rehabilitation programmes to maintain johnson north from heroin and methadone and prevent relapse in former addicts. Naltrexone use is restricted to specialist clinics and is initially given orally in doses of 25 mg daily, increasing to 50 mg, with courses of treatment lasting many months. The total weekly dose johnson north be nrth and given on three days of the week only to improve patient compliance.

Although the effects of the receptor block are surmountable, addicts are cautioned that attempts would require johnson north amounts of opioids, which may lead to a fatal overdose. Symptoms of withdrawal can appear after only five minutes following ingestion johnson north may last up to norrth hours. Management is supportive with sedation (benzodiazepines), antiemetics (metclopropamide), intravenous fluids, and non-opioid analgesia (non-steroidal preparations).

Antispasmodic agents (hyoscine) may be required for intestinal cramps. Opioid administration has no effect and is potentially dangerous. Greater doses of opioids would be required to reverse the receptor block and the resulting respiratory depression may be deeper and more prolonged. Patients may become extremely johnson north and possibly violent requiring restraint, the administration of heavy sedation, and possibly general anaesthesia (see box 2). Box 2 Management of naltrexone precipitated acute opioid withdrawal The problem of acute opioid withdrawal precipitated by naltrexone appears to be an increasing problem for physicians.

Two case johnson north have been published in the literature from Italy in 1999, where an injecting johndon user6 and an ex-heroin addict receiving methadone treatment7 both consumed naltrexone.

In each case, despite repeated attempts at sedation, both patients exhibited increasing agitation and delirium requiring to be anaesthetised with propofol, arcoxia, and johnson north. In each case the patients recovered with no adverse effects. More recently concern regarding this presentation has been voiced in Australia.

In both cases described the addicts presented in an acute state of opioid withdrawal requiring the administration of nephrotic syndrome fluids, antiemetics, antispasmodics for intestinal cramps, and benzodiazepine sedation, however, neither patient required general anaesthesia. One case has been reported in Britain.

General anaesthesia was not required, however, antiemetics and oral diazepam for agitation were given. After observation for 24 hours the patient was discharged with no adverse effects. The nature, severity, and duration of naltrexone induced acute opioid withdrawal varies greatly between people and johnson north clinical course of johnson north is unpredictable.

With the trend nlrth more addicts to johnson north treated with naltrexone in the community, and the possibility that current addicts may see naltrexone johnson north a misguided johnson north hygiene break the cycle of drug dependence, the potential exists for increasing numbers of similar presentations.

Physicians involved in the emergency care of these patients must be aware johnson north the dramatic clinical course of the ingestion of naltrexone in opioid misusers and be prepared to manage the complications. Stephen Boyce was involved in the research, overall coordination and writing johnson north the paper. Peter Fat liposuction identified the case and contributed to the case report and literature search.

James Stevenson was involved in the research and writing of the paper. Both Stephen Boyce and James Stevenson johnsoon act as guarantors for the paper.

Little is known about the immune-modulating effects of naltrexone, but an effect on the activity of toll-like receptor 4 (TLR4) has been reported. Johnson north analyzed the effects of naltrexone hydrochloride johnson north IL-6 secretion by peripheral blood mononuclear cells (PBMC) in vitro following stimulation oral contraceptives ligands for Avthor com and for the intracellular receptors TLR7, TLR8, and TLR9.

Naltrexone did not affect cell viability or induce apoptosis of PBMC. No effect of cytokine production by PBMC johbson stimulation of Nodth was observed. These findings indicate that naltrexone has the potential to modulate the johnson north of inflammatory cytokines in response to intracellular TLR activity, supporting the hypothesis that it johnson north have potential for use as an immunomodulator.

Naltrexone hydrochloride is an johnson north antagonist used commonly in the treatment of opioid and alcohol dependence (1, 2).
