Naltrexone for eating disorders
The treatment response characteristics are more like bulimia than other forms of obesity. We have shown the opiate antagonist naltrexone to attenuate bulimia nervosa in controlled clinical trials. We report here a response to naltrexone in a subject with BED similar to that previously reported for the larger population of bulimic subjects.
Three consecutive periods of drug, placebo and double dose drug were used, with the order of the first two periods double blind until after the data analysis. Symptoms were reduced in the naltrexone compared to placebo period. Statistical significance was demonstrated using time series analysis for this 'n of one' study. Psychotherapy was carried out throughout all periods. Significant decreases in urge to binge were obtained during naltrexone administration compared with control sessions.
Baseline plasma beta-endorphin concentrations for the bulimic adolescent were not different from those of nonbulimic controls, but plasma beta- endorphins increased significantly during naltrexone administration. After discharge from the hospital, the adolescent refused to take naltrexone because she felt she could not deal with her life without the "pleasure of binging.
Involvement of the endogenous opioids in the pathophysiology of hypothalamic amenorrhea, by inhibition of hypothalamic GnRH secretion, has been demonstrated in some cases. Chronic blockade of the endogenous opioids with the long-acting opioid antagonist naltrexone could result in increased gonadotropin secretion and ovulation induction in these cases.
Hence, bulimia patients need greater vagus nerve stimulation in order to stop eating. Interestingly, studies have also shown that people suffering from bulimia have high pain thresholds, compared to non-bulimics. The antiemetic effects of ondansetron, which reduce vagus nerve activity by acting on the 5-HT3 serotonin receptor, seem to decrease vomiting while increasing the number of normal meals eaten.
Finally, a third path toward treatment has been sparked by research on opioid receptors. Decreased endogenous opioid activity may also underpin bulimia.
Bulimics showed decreased opioid receptor binding in the insula, another area of the brain implicated in MRI studies of addiction. Opioid receptors are involved in the processing of the reward value of food. This suggests that a drug like naltrexone, which blocks opiate receptors, might also have a role to play in the treatment of bulimia. Regional mu-opioid receptor binding in insular cortex is decreased in bulimia nervosa and correlates inversely with fasting behavior.
Journal of nuclear medicine: Serotonin alterations in anorexia and bulimia nervosa: In the melanocortin system, bupropion stimulates activity of pro-opiomelanocortin POMC cells in the hypothalamus and naltrexone amplifies this effect by blocking the endogenous opioid-mediated autoinhibition of POMC cells. These adverse events are generally mild to moderate in severity and occur early in the treatment course during dose escalation.
Small increases in mean blood pressure and pulse rate have been reported in clinical trials. The authors noted that only 2. This low utilization means that the long-term effects of these medications remain largely unknown.
In essence, this combination of medications, through its combined mechanism of action, takes away the compulsive feeding behavior and the pleasure of feeding, leading to weight loss. All COR trials were multicenter, double-blinded, randomized, placebo-controlled, and included a 3-week dose escalation period from one tablet every morning, to two tablets twice a day.
COR-Diabetes included the same study design but focused on patients with diabetes.
