cardiovascular effects of opioid withdrawal have long been studied. it was reported that patients with underlying ischemic heart disease and atherosclerotic vessels may be complicated by a sudden physical and emotional stress due to withdrawal syndrome. but some other believes sudden increase in catecholamine level as a sympathetic overflow might effect on heart with and without underlying isch...

background: the aim of this study was to compare the effectiveness of methadone detoxification with traditional method of gradual decrement in the abused amount of the refined opium dross (shireh) to control withdrawal syndrome in shireh-addicted patients. methods: in this study, two groups of shireh addicts were compared. the first group was treated by methadone and the second group by gradual...

background: matricaria chamomilla (mc) contains flavonoids such as apigenine which exerts benzodiazepine-like activity, therefore it may be helpful for morphine withdrawal syndrome treatment. in this study the effects of peripheral (ip) injection of mc hydroalcoholic extract was investigated on morphine withdrawal syndrome signs in rats. material &methods;: 24male wistar rats (200-250gr) were a...

combined use of an opioid with a psychostimulant is popular among drug abusers. such “polydrug use” may increase drug effects or attenuate adverse effects of either drug alone. we proposed that a combination of methamphetamine (meth) and morphine may change physical opioid withdrawal symptoms. adult male rats were chronically injected with cumulative subcutaneous (s.c.) doses of morphine, meth ...

Background: Gamma-amino butyric acid (GABA) agonists have been effective in the treatment of withdrawal from benzodiazepines, sedatives and alcohol, and reducing the craving for cocaine. Valproate is a GABAergic drug effective in the treatment of neuropathic pain and also in withdrawal from benzodiaepines, sedatives, and alcohol.

The present study has investigated the effects of nicotine on the strength of physical and psychological dependency in single and repeated doses morphine administrated rats. Methods: Male Wistar rats were subjected to morphine consumption with single or frequent dose protocols. ...

introduction: it has been shown that orexin peptides have a role in opioid withdrawal behaviors. orexin-expressing neurons that are present in the hypothalamic nuclei send dense projections to the locus coeruleus (lc). withdrawal syndrome is temporally associated with hyperactivity of lc neurons. however, lc neurons do not show withdrawalinduced hyperactivity in the brain slices from morphine-d...

methadone is widely being used for opioid substitution therapy. however, the administration of methadone to opioid dependent individual is frequently accompanied by withdrawal syndrome and chemical dependency develops. other than that, it is also difficult to retain patients in the treatment programme making their retention rates are decreasing over time. this article is written to higlights th...
