We report the case of a neonate who likely developed symptoms of Neonatal Abstinence Syndrome after in-utero exposure to gabapentin for treatment of maternal chronic pain. The neonate developed symptoms of hypertonicity, tremor, and poor feeding twelve hours after delivery. Although the neonate wasbriefly exposed to the benzodiazepine alprazolam and the opioid oxycodone, the withdrawal symptoms...

Opioid is a popular drug of abuse and addiction. We evaluated acupuncture as a non-pharmacological treatment with a focus on managing withdrawal symptoms. Electrical stimulation at a low frequency (2 Hz) accelerates endorphin and encephalin production. High-frequency stimulation (100 Hz) up-regulates the dynorphin level that in turn suppresses withdrawal at the spinal level. The effect of 100-H...

The present study focused on the evaluation of a role of opioid system in nicotine-induced antinociception and physical dependence in mice. The results indicate that nicotine (3 mg/kg) produced a significant antinociception in the hot plate test. Additionally, the opioid receptor antagonist naloxone (0.5 and 1 mg/kg), dose-dependently attenuated this effect. Our second experimental protocol con...

Frequent tanning has reinforcing properties. We tested whether opioid antagonism blocks potential reinforcing effect of indoor tanning in 8 frequent tanners and 8 infrequent tanner control subjects. Opioid blockade reduced ultraviolet preference in frequent tanners. Four of 8 frequent tanners, but no infrequent tanners, exhibited withdrawal-like symptoms with naltrexone administration. A limita...

The regulation of glutamate (Glu) release from the excitatory input to dopamine cells in the ventral tegmental area (VTA) during acute withdrawal from morphine was studied in slices from animals treated for 6-7 d with morphine. EPSCs were inhibited by opioid agonists acting at micro-subtype receptors but not by selective delta- or kappa-subtype agonists. The opioid inhibition was reduced by 65%...

Opioid drugs are potent modulators of many physiological and psychological processes. When given acutely, they can elicit the signature responses of euphoria and analgesia that societies have coveted for centuries. Repeated, or chronic, use of opioids induces adaptive or allostatic changes that modify neuronal circuitry and create an altered normality - the "drug-dependent" state. This state, a...

Given that buprenorphine + naloxone is prescribed for opioid-dependent pregnant women, it is important to examine the extent to which it differs from buprenorphine alone, methadone, or methadone-assisted withdrawal on neonatal and maternal outcomes. Summary statistics on maternal and neonatal outcomes were collected from 7 previously published studies examining treatment for opioid-dependent pr...
