Background: Benzodiazepine (BZD) toxicity alone or with other drugs is common in poisoning emergency departments of Iran. The aim of this study was to evaluate the cardiovascular findings in patients with benzodiazepine poisoning upon admission to the emergency department. Methods: In a prospective study which was followed by retrospective analysis, 267 patients poisoned with BZD were evalu...

Objective: Regarding the anticonvulsant effects of Satureja hortensis (S. hortensis) in Avicenna’s book: canon of medicine; the present study was undertaken to evaluate the anti- eplileptic effects of S. hortensis aqueous and ethanolic aerial part extracts. Furthermore, the mechanisms of their anticonvulsant activities were also evaluated. Materials and Methods: Seizure was induced by Pentylen...

The study was designed to investigate the effect of ketamine on convulsive behaviour using maximal electroshock (MES) test. An attempt was also made to study the possible receptor mechanisms involved. MES seizures were induced in mice via transauricular electrodes (60 mA, 0.2sec). Seizure severity was assessed by the duration of tonic hindlimb extensor phase and mortality due to convulsions. In...

This paper reviews studies examining the pharmacological interactions and epidemiology of the combined use of opioids and benzodiazepines (BZDs). A search of English language publications from 1970 to 2012 was conducted using PubMed and PsycINFO(®). Our search found approximately 200 articles appropriate for inclusion in this paper. While numerous reports indicate that the co-abuse of opioids a...

Isoliquiritigenin (ILTG) is a chalcone compound and shows various pharmacological properties, including antioxidant and anti-inflammatory activities. In recent study, we have reported a novel role of ILTG in sleep through a positive allosteric modulation of gamma-aminobutyric acid type A (GABAA)-benzodiazepine (BZD) receptors. However, the effect of ILTG in GABAAR-mediated synaptic response in ...

Two novel series of 3,4-dihydroisoquinolin with heterocycle derivatives (4a-t and 9a-e) were synthesized and evaluated for their anticonvulsant activity using maximal electroshock (MES) test and pentylenetetrazole (PTZ)-induced seizure test. All compounds were characterized by IR, ¹H-NMR, 13C-NMR, and mass spectral data. Among them, 9-(exyloxy)-5,6-dihydro-[1,2,4]triazolo[3,4-a]isoquinolin-3(2H...

to obtain drugs which are more selective at benzodiazepine (bzd) receptors, design and synthesis of functionally selective ligands for bzd receptors is the current strategy of our pharmaceutical chemistry department. the affinity of newly synthesized ligands is assessed by radioligand receptor binding assays. based on our previous studies, 2-phenyl-5-oxo-7-methyl-1,3,4-oxadiazolo[a,2,3]-pyrimid...
