Zolpidem is a short-acting imidazopyridine hypnotic that is an agonist at the gamma-aminobutyric acid A type (GABAA) receptor. It has been suggested that it acts selectively on alpha1 subunit-containing GABAA benzodiazepine (BZ1) receptors presenting (contrary to classic benzodiazepines) low or no affinity for other subtypes. Therefore, it has been proposed(More)
Thyroid hormone (TH) is critical in cardiac cell differentiation (regulating contractile proteins and cell geometry) and this effect could be potentially exploited therapeutically in reversing the process of de-differentiation which underlies postischemic cardiac remodeling. Acute myocardial infarction was induced in male Wistar rats by ligating left(More)
Transdermal fentanyl is an opioid analgesic that is effective on chronic pain, and which appears to be advantageous due to several factors such as ease of administration, the relatively stable serum concentration and long dose intervals. Nevertheless, the danger of abuse and dependence exists among patients who are prescribed fentanyl patches. We present a(More)
BACKGROUND Alcohol-induced changes in thyroid function may contribute to the development of mood disorders such as depression and anxiety that almost invariably coexist in alcohol-dependent individuals. The aim of the present study was to investigate the severity of liver dysfunction and thyroid activity in correlation with anxiety and depressive-like(More)
Zolpidem is an imidazopyridine hypnotic that is believed to act selectively at alpha(1) subunit-containing gamma-aminobutyric acid type A (GABA(A)) receptors and thus to have minimal abuse and dependence potential. We present three cases of zolpidem abuse and dependence in which the drug was used not for sedation but for stimulation and anxiolysis. All of(More)
A case is presented of a 30-year-old man, prescribed zolpidem for insomnia arising from cocaine abuse, who sought to use this hypnotic to reduce his craving for cocaine. However, after taking cocaine and up to 300 mg/day zolpidem, he became euphoric and hyperactive. It is suggested that at high doses, zolpidem, like cocaine, has a stimulatory effect on the(More)
OBJECTIVE Alcohol intake is a major cause of liver cirrhosis as well as chronic liver disease, and commonly coexists with mood disorders such as depression and anxiety. The aim of the present study was to investigate the possible correlation between liver dysfunction related to alcohol intake with anxiety and depressive-like symptomatology prior to and(More)
Purpose. The present study investigated the potential effects of long-term T3 treatment on glioma tumor cell lines. Thyroid hormone action on cell growth, differentiation and survival during development may be of therapeutic relevance Methods and Results 1321N1 cell line, an astrocytoma grade II, and U87MG, a glioblastoma grade IV, were exposed for 2 and 4(More)
