Clinical pharmacy, 6(7), 533-547 (1987-07-01)
The chemistry, pharmacology, pharmacokinetics, clinical efficacy, adverse effects, drug interactions, dosage, and cost and availability of midazolam hydrochloride are reviewed. The anxiolytic, sedative, hypnotic, anticonvulsant, muscle-relaxant, and amnesic properties of midazolam are similar to those of other injectable benzodiazepines. Midazolam

Anesthesia and analgesia, 96(5), 1386-1391 (2003-04-23)
Epidurally administered midazolam can potentiate analgesia by epidural bupivacaine. However, whether this effect is synergistic or additive is not known. In this study, we investigated the spinally-mediated analgesic interaction between midazolam and bupivacaine by using the tail-flick and formalin tests

This pilot study introduces the aerosolized route for midazolam as an option for infant and pediatric sedation for computed tomography imaging. This technique produced predictable and effective sedation for quality computed tomography imaging studies with minimal artifact and no significant

The influence of the size and turnover kinetics of the enterocyte-based lymph lipid precursor pool (LLPP) on intestinal lymphatic drug transport has been examined. Mesenteric lymph duct-cannulated rats were infused intraduodenally with low (2-5 mg/h) or high (20 mg/h) lipid-dose

Patients treated with sunitinib show substantial inter-patient variability in drug exposure (~30-40 %), which is largely unexplained. Since sunitinib is metabolized by cytochrome P450(CYP)3A4, variability in the activity of this enzyme may explain a considerable proportion of this inter-patient variability.
