Midazolam is a short-acting benzodiazepine that is widely used in anesthesia. Despite its widespread clinical use, detailed information about cardiac side effects of midazolam is largely lacking. Using the double-electrode voltage clamp technique, we studied pharmacological effects of midazolam on heterologously expressed Kv1.5 channels underlying atrial repolarizing current I(Kur). Midazolam d...

The 30-minute ratio of 1'-hydroxymidazolam:midazolam plasma concentrations has been used as a measure of midazolam clearance in liver transplant patients. This study determined if a single concentration of 1'-hydroxymidazolam or the ratio of 1'-hydroxymidazolam:midazolam could be used to predict midazolam clearance in healthy subjects. Plasma midazolam and 1'-hydroxymidazolam concentrations fro...

introduction: both midazolam and promethazine are recommended to be used as sedatives in many studies but each have some side effects that limits their use. combination therapy as an alternative method, may decreases these limitations. therefore, this study aimed to compare midazolam with midazolam-promethazine regarding induction, maintenance, and recovery characteristics following pediatric p...

Midazolam is almost exclusively metabolized by cytochrome P450 3A (CYP3A) isoenzymes. Therefore, midazolam is used as a probe to determine CYP3A levels in humans and rats. A prerequisite for longitudinal determination of CYP3A expression levels using midazolam as a probe is that midazolam itself has no effect on the expression of CYP3A. In the present study, we analyzed the mRNA levels and enzy...

the objective of this study was to investigate the effect of intranasal phototherapy on nasal microbial flora in patients with allergic rhinitis. this prospective, self-comparised, single blind study was performed on patients with a history of at least two years of moderate-to-severe perennial allergic rhinitis that was not controlled  by  anti-allergic drugs.  thirty-one  perennial  allergic r...

intrathecal administration of midazolam has been reported to have antinociceptive action, and to be an effective analgesic agent. in this prospective double-blind study we aimed to evaluate the postoperative effects of intrathecal midazolam with lidocaine following perineal operation. forty patients were randomly allocated to two groups: 20 patients in the control group received 2 ml of 5% heav...

BACKGROUND Midazolam may suppress conditioned fear after an aversive event by disrupting the memory trace formed during conditioning, by altering the emotional part of the aversive event, or by the combination of both effects. The purpose of the present study was to determine whether affective-related processes contribute to the amnesic-like effects of midazolam on aversive events. METHODS Th...

BACKGROUND Soman, a potent irreversible acetylcholinesterase (AChE) inhibitor, induces delayed neuronal injury by reactive oxygen species (ROS). Midazolam is used in patients with pathologic effects of oxidative stresses such as infection, hemodynamic instability and hypoxia. We investigated whether midazolam protects the Central Nervous System (CNS) from soman intoxication. The present study w...

Here, we examined how repetition under midazolam, a benzodiazepine that prevents the storage of novel associations, affects cued-recall performance of paired-associates. We contrasted word pairs that were initially studied and tested repeatedly without any successful recall prior to the midazolam injection, with other pairs that were studied for the first time after the injection of midazolam. ...

Our study sought to determine whether premedication with intramuscular midazolam would decrease the time to induction of anaesthesia with intravenous midazolam, and if so whether induction of anaesthesia would be as rapid as with thiopentone or ketamine, intravenously. Eight-nine patients, ASA physical status I or II, received midazolam 0.2 mg X kg-1, thiopentone 3.0 mg X kg-1, or ketamine 2.0 ...
