The cytochrome P450 3A (CYP3A) enzymes represent one of the most important drug-metabolizing systems in humans. Recently, our group has generated cytochrome P450 3A knockout mice to study this drug-handling system in vivo. In the present study, we have characterized the Cyp3a knockout mice by studying the metabolism of midazolam, one of the most widely used probes to assess CYP3A activity. We expected that the midazolam metabolism would be severely reduced in the absence of CYP3A enzymes. We used hepatic and intestinal microsomal preparations from Cyp3a knockout and wild-type mice to assess the midazolam metabolism in vitro. In addition, in vivo metabolite formation was determined after intravenous administration of midazolam. We were surprised to find that our results demonstrated that there is still marked midazolam metabolism in hepatic (but not intestinal) microsomes from Cyp3a knockout mice. Accordingly, we found comparable amounts of midazolam as well as its major metabolites in plasma ...
Midazolam is a short-acting benzodiazepine in adults with an elimination half-life of one to four hours; however, in the elderly, as well as young children and adolescents, the elimination half-life is longer. Midazolam is metabolised into an active metabolite alpha1-hydroxymidazolam. Age related deficits, renal and liver status affect the pharmacokinetic factors of midazolam as well as its active metabolite. However, the active metabolite of midazolam is minor and contributes to only 10 percent of biological activity of midazolam. Midazolam is poorly absorbed orally with only 50 percent of the drug reaching the bloodstream. Midazolam is metabolised by cytochrome P450 (CYP) enzymes and by glucuronide conjugation. The therapeutic as well as adverse effects of midazolam are due to its effects on the GABAA receptors; midazolam does not activate GABAA receptors directly but, as with other benzodiazepines, it enhances the effect of the neurotransmitter GABA on the GABAA receptors (↑ frequency of Cl ...
TY - JOUR. T1 - Inhibitory effect of midazolam on MMP-9, MMP-1 and MMP-13 expression in PMA-stimulated human chondrocytes via recovery of NF-κB signaling. AU - Wang, Jen Jui. AU - Huan, Steven Kuan Hua. AU - Hsieh, Kuo Hsien. AU - Chou, Hsiu Chu. AU - Hsiao, George. AU - Jayakumar, Thanasekaran. AU - Sheu, Joen Rong. PY - 2013/4. Y1 - 2013/4. N2 - Introduction: Midazolam, a benzodiazepine, has a hypnotic effect and is widely used as an intravenous sedative. Past studies have clearly established that midazolam has beneficial effects in attenuating ischemia-reperfusion injury more than other currently used sedative drugs. However, the role of midazolam on chondroprotection via inhibition of matrix metalloproteinases (MMPs) is warrant investigation. The aim of this study was to examine the mechanisms of action of midazolam on MMP expression via nuclear factor κB (NF-κB) signaling in activated chondrosarcoma cells maintained in vitro. Material and methods: Chondrocytes, SW1353 cells, were ...
Involuntary movement during and after neuraxial anesthesia, such as spinal and epidural anesthesia, is rarely observed. In this report, we describe a case of myoclonus-like involuntary movement of the upper extremities in a patient undergoing a planned repeat cesarean section under spinal anesthesia with bupivacaine that completely subsided after 2mg midazolam administration. The myoclonus-like movement never recurred or caused any apparent neurological side effects. No abnormal sensation or spontaneous pain of the upper extremities was observed. The patient was discharged on foot on post-operative day 3.
Midazolam Injection contains midazolam a Schedule IV control substance.. Midazolam was actively self-administered in primate models used to assess the positive reinforcing effects of psychoactive drugs.. Midazolam produced physical dependence of a mild to moderate intensity in cynomolgus monkeys after 5 to 10 weeks of administration. Available data concerning the drug abuse and dependence potential of midazolam suggest that its abuse potential is at least equivalent to that of diazepam.. Withdrawal symptoms, similar in character to those noted with barbiturates and alcohol (convulsions, hallucinations, tremor, abdominal and muscle cramps, vomiting and sweating), have occurred following abrupt discontinuation of benzodiazepines, including midazolam. Abdominal distention, nausea, vomiting, and tachycardia are prominent symptoms of withdrawal in infants. The more severe withdrawal symptoms have usually been limited to those patients who had received excessive doses over an extended period of time. ...
TY - JOUR. T1 - Oral midazolam for sedation in minor oral operations in children. T2 - A retrospective study. AU - Kohjitani, Atsushi. AU - Higuchi, Hitoshi. AU - Shimada, Masahiko. AU - Miyawaki, Takuya. PY - 2008/6. Y1 - 2008/6. N2 - Our aim was to find out the optimal dose of oral midazolam to sedate children according to age. Thirty-five patients aged 10 or under who had minor oral operations under sedation with midazolam were enrolled. Correlations between age (X) and dose of midazolam (mg/kg; Y) were analysed by Pearsons correlation coefficient, and relations were fitted by simple regression. Doses of midazolam were significantly reduced as age increased (Y = 0.969 - 0.04X; R = 0.48) in the satisfactory group (n = 25), whereas those in the overdose group (n = 10) (patients who vomited, became agitated, or took some time to come round) were significantly higher, decreased with age, and showed a better correlation coefficient (Y = 1.375 - 0.65X; R = 0.78). These findings suggest that both ...
Intramuscular midazolam is at least as safe and effective as intravenous lorazepam for the prehospital management of status epilepticus. In his blog EM Literature of Note, Dr Ryan Radecki looks forward to a similar trial comparing nasal midazolam, which would reduce the risk from injections. Read his full critique here. Buccal midazolam 0.5 mg/kg is of course also an option, as described in the Advanced Paediatric Life Support manual:. If using the buccal route, draw up the higher dose (0.5mg) of the IV preparation using a needle (to avoid any fragments of glass from the ampoule) and after removing the needle, inject the drug into the buccal area between the lower bottom lip and the gum margin at the side of the mouth. Buccal midazolam is twice as effective as rectal diazepam, but both drugs produce the same level and degree of respiratory depression.. ...
There were no significant differences between two groups with respect to diastolic blood pressure and respiratory rate before and after drug administration. However, the data showed systolic blood pressure was significantly lower in the midazolam group than in the diazepam group at 15 minutes and 30 minutes after drug administration. It was found that there were significant differences between the groups with respect to heart rate at various time intervals after drug administration.. DISCUSSION: Previous studies have shown that intramuscular midazolam is a good preoperative medicant superior to diazepam. Since diazepam: the prototype BZDs, administered intramuscularly is erratically absorbed and has poor local tolerability at the site of injection, oral diazepam is widely used by many anesthesiologist in Nepal for premedication. It was therefore considered appropriate to study intramuscular midazolam in comparison with oral diazepam for premedication.. This present study drew inference that ...
AIMS To identify the prevalence and correlates of midazolam injection among injecting drug users in Thailand. DESIGN Serial cross-sectional mixed-methods study. SETTING Bangkok, Thailand. PARTICIPANTS A total of 435 adults who had injected drug(s) in the past 6 months were recruited through peer outreach and word of mouth in Bangkok in 2011. MEASUREMENTS Multivariable logistic regression was used to analyze self-reported data collected through an interviewer-administered survey in July-October 2011 (n = 435). Additionally, qualitative data were collected in June-July 2009 (n = 10) and analyzed to explore the health problems attributable to midazolam injection. FINDINGS Among 435 survey participants, the prevalence of daily midazolam injection in the past 6 months was 37.0% (95% confidence interval: 32-42). While 75.8% of the daily midazolam injectors identified heroin as their drug of choice, 91.8% of these individuals reported substituting heroin with midazolam when heroin was unavailable.
In the EPM when comparing mean speed, the crocin group was significantly increased compared to the midazolam + crocin group and midazolam group was significantly decreased compared to the crocin, flumazenil + crocin, and vehicle groups. Additionally, the flumazenil + crocin group was significantly increased compared to the midazolam + crocin group. When comparing the mean time mobile, the crocin group was significantly increased compared to the midazolam group. When comparing open arm time ratio, the midazolam group was significantly increased compared to all other groups. In the FST when comparing mean time mobile, the midazolam + crocin group was significantly increased compared to the crocin, vehicle, and midazolam groups ...
BACKGROUND: Benzodiazipines, especially Midazolam, are the most frequently used agents for gastrointestinal endoscopy worldwide. Among the parameters the quality of sedation is determined by patients satisfaction assessed after endoscopy. This approach is misleading as the potent amnestic effect of Midazolam conceals pain actually suffered during the endoscopic procedure involving distraction of the endoscopists (poor babies) from their actual tasks by audible reactions and defense movements. In this study, we eliminated the influence of patients amnesia on the assessment of the quality of sedation and rather interviewed endoscopists and their assistant personnel about their experience with Midazolam sedation. We replaced the mostly vague term compliance (compliance, here we have the number one reason for Midazolam use) by terms which unequivocally describe the reactions of the patient during unpleasant endoscopy. METHODS: A short survey consisting of 12 questions was developed. The ...

Introduction. Ketamine is an old and generally well accepted analgesic used in the intra- and perioperative setting. Several studies demonstrated the effectiveness of ketamine in the postoperative setting.. A new formulation of S-ketamine as an intranasal spray device was tested in our hospital in 8 healthy volunteers (unpublished data, EKBB 351/08). 20 mg of S-ketamine were administered intranasally and compared with S-ketamine i.v. and i.m.. None of the volunteers had serious adverse effects or complications. A preliminary data analysis shows a clear analgesic effect and good absorption of the intranasal S-ketamine.. As a next step we would like to investigate the effect of S-ketamine intranasal spray combined with midazolam intranasal spray in a group of postoperative spinal surgery patients. The rational for the combination of intranasal S-ketamine and midazolam is the well known midazolam antagonising effect of ketamine induced psychomimetic adverse effects. Furthermore we know from other ...
NOTE: CONTAINS BENZYL ALCOHOL (see WARNINGS and PRECAUTIONS/Pediatric Use). Midazolam injection is a potent sedative agent that requires slow administration and individualization of dosage. Clinical experience has shown midazolam to be 3 to 4 times as potent per mg as diazepam. BECAUSE SERIOUS AND LIFE-THREATENING CARDIORESPIRATORY ADVERSE EVENTS HAVE BEEN REPORTED, PROVISION FOR MONITORING, DETECTION AND CORRECTION OF THESE REACTIONS MUST BE MADE FOR EVERY PATIENT TO WHOM MIDAZOLAM INJECTION IS ADMINISTERED, REGARDLESS OF AGE OR HEALTH STATUS. Excessive single doses or rapid intravenous administration may result in respiratory depression, airway obstruction and/or arrest. The potential for these latter effects is increased in debilitated patients, those receiving concomitant medications capable of depressing the CNS, and patients without an endotracheal tube but undergoing a procedure involving the upper airway such as endoscopy or dental (see Boxed WARNING and WARNINGS).. Reactions such as ...
TY - JOUR. T1 - Influence of midazolam on induction dose of propofol. AU - Kapoor, Ruchi. AU - Gopalakrishna, K.. AU - Ambareesha, M.. PY - 2009/1/1. Y1 - 2009/1/1. N2 - Patients & Methods: Fifty ASA Class 1 and 2 adult patients posted for elective surgery were randomly allocated to control and study groups with 25 patients in each groups. The control groups received 10ml of saline while the study group received 0.04mg kg-1 of midazolam diluted to 10ml of saline over one minute. Three minutes later in both the groups, general anaesthesia was induced with propofol 10mg boluses every 15 seconds till endpoint is achieved. The endpoint was defined as first lack of response to command i.e the patient is unable to lift the hand when asked to do so. The dose at which end is achieved is noted. The results were analysed by chi-square test. Results: The dose of propofol required for induction in control group was 2.23mg Kg-1 compared to study group which required 1.3mg kg -1. Thus a 42% reduction in ...
There is no randomized study carried out in order to compare their pharmacokinetic parameters although midazolam, as a sedative, has been widely administered via continuous infusion as well as intermittent bolus doses in mechanically ventilated critically ill patients. We prospectively investigated the effect of these two principal methods on pharmacokinetic parameters in 23 of mentioned patients (16 males, 7 females) with the mean (± SD) age of 41.22 ± 17.5. All patients received total dose of 72 mg throughout the test days, 9 of whom received 1 mg/h (continuous infusion) and the rest obtained 4 mg / 4 h (intermittent bolus doses). Blood samples were collected at 8 and 4 h prior to the end time of drug administration (zero time), zero time and 4, 8, 12, 20 and 30 h after it. APACHE (Acute Physiology and Chronic Health Evaluation) II required data was recorded daily and the patients mean score was 16.26 ± 4.38. The mean (± SD) value of pharmacokinetic parameters of Midazolam in continuous infusion
Through a qualitative review of the literature, Ariano and colleagues concluded that no clinically important difference in recovery rates from sedation existed between diazepam and midazolam. Clinicians must not assume from this study, however, that diazepam and midazolam can be interchanged freely for short-term sedation. The lack of a validated sedation assessment tool makes it difficult to know if the degrees of recovery were similar in the compared studies (1). Also, the question of whether equipotent doses of drugs were used still remains. In most of the reviewed studies, midazolam was considered to be approximately twice as potent as diazepam; however, recent clinical evidence indicates that this ratio may be too low. According to 1 study, the diazepam-to-midazolam potency ratio may be closer to between 3:1 and 6:1 than to 2:1 (2). This study does raise an important point about short-term sedation. Elimination half-lives of benzodiazepines cannot be used to predict recovery time. Because ...
Midazolam must never be used without individualization of dosage. The initial intravenous dose for sedation in adult patients may be as little as 1 mg, but should not exceed 2.5 mg in a normal healthy adult. Lower doses are necessary for older (over 60 years) or debilitated patients and in patients receiving concomitant narcotics or other central nervous system (CNS) depressants. The initial dose and all subsequent doses should always be titrated slowly; administer over at least 2 minutes and allow an additional 2 or more minutes to fully evaluate the sedative effect. The use of the 1 mg/mL formulation or dilution of the 1 mg/mL or 5 mg/mL formulation is recommended to facilitate slower injection. Doses of sedative medications in pediatric patients must be calculated on a mg/kg basis, and initial doses and all subsequent doses should always be titrated slowly. The initial pediatric dose of midazolam for sedation/anxiolysis/amnesia is age, procedure, and route dependent (see DOSAGE AND ...

Questionários subjetivos acerca dos principais receios e queixas relativamente à BF foram aplicados antes e ...
INTRODUCTION: CYP3A is responsible for the metabolism of numerous endogenous and exogenous compounds. Several substrates of CYP3A have been investigated to assess the CYP3A-metabolizing capacity of an individual in an attempt to predict the rate of metabolism of other CYP3A substrates. Two such tests of CYP3A activity are the midazolam plasma clearance after its intravenous administration and the 6beta-OH cortisol urinary ratio. Possible correlations between these 2 tests were investigated before and after treatment with rifampin in a group of healthy volunteers. METHODS: Pharmacokinetic parameters of midazolam and 6beta-OH cortisol urinary ratio were evaluated in 8 volunteers before and after 6 days treatment with rifampin, a potent inducer of CYP3A, and after cessation of rifampin treatment. RESULTS: Midazolam systemic clearance and the 6beta-OH cortisol urinary ratio were significantly higher at Days 7 and 10 than at Day 0. There was a strong positive correlation between these 2 parameters (r ...

Background: Neonatal respiratory distress syndrome (NRDS), a life-threatening pulmonary disorder, involves 1% of all deliveries worldwide. Shallow breathing causes restlessness in infants, which itself affects pulmonary function; thus, sedative medications are used to preserve better pulmonary function. There are different opinions about the benefits and superiority of these drugs. Objective: The study purposed to assess and compare the effects of fentanyl and midazolam on the required time of mechanical ventilation in infants with respiratory distress syndrome (RDS). Methods: In this randomized clinical trial, 60 infants with RDS were randomly allocated to 2 groups (30 infants each); the first group underwent sedation with midazolam (0.1 mg/kg), and the second group received 0.5 mcg/kg of fentanyl during ventilation. The duration of hospitalization, required time of ventilation, drug complications, feeding intolerance, as well as pneumothorax incidence and need for re-intubation were recorded and
title:A Comparative Study between Intramuscular Midazolam and Oral Clonidine As A Premedication For General Anesthesia. Author:Jignasa J Patel, Kalpana A Desai. Keywords:Premedication, Midazolam, Clonidine, Sedative. Type:Original Article. Abstract:Background: Most anesthesiologists agree on the need for efficient pre-medication. The pattern of desired effects of a pre-medication is however, complex and includes relief of anxiety, sedation and relaxation of the patient. The present study was undertaken to compare the effects of Midazolam and clonidine as premedication. Methodology: A comparative study between midazolam and clonidine as a premedication for general anesthesia was conducted. Patients were divided in two groups: Group I: Inj. Midazolam 0.07 mg/kg i.m. before surgery; Group II Tab.Clonidine 4µg/kg oral, 2 hours before surgery. Pulse rate, blood pressure, state of excitement, apprehension and sedation were noted at the time of giving premedication. Results: Majority of cases in both ...
Most of the preschool children suffer from severe anxiety and apprehension before operation. This can largely affect the smooth conductance and emergence from anaesthesia. Above all this can lead to development of maladaptive behavioral responses in later part of life. Midazolam in current time has emerged as an ideal premedicant having all the desirable properties in this regard. It has been used by several routes for premedication. Each has its own advantage and disadvantage. The search for an ideal route and dose still exists. So the current study was planned to find out the efficacy of midazolam intranasally. Forty five paediatric patients of 2-5 years of age belonging to ASA I& II, scheduled for minor elective surgery were selected for this study. Patients were divided in three equal groups to receive normal saline (Group I), 0.2 mgkg-1 midazolam (Group II), or 0.3mgkg-1 midazolam (Group III) intranasally. Vital parameters and level of sedation (using a sedation scale) were assessed before ...
Midazolam is benzodiazepine with anxiolytic, hypnotic, sedative and anticonvulsive actions, producing anterograde amnesia. It is often used in the pediatric population due to its favourable characteristics: rapid onset, short duration of action and the haemodynamic stability of the patient. Midazolam is used for preoperative and procedural sedation, for induction and maintenance of anesthesia, for sedation in intensive care units and as an anticonvulsive agent in children ...
The effects of alfentanil on the midazolam dose-response curve for hypnosis was studied with response to the verbal command as an end point in 95 patients. The analgesic effect of alfentanil was studied by measuring the threshold for pain caused by pressure on the trapezius muscle with the use of a dolorimeter in 21 patients. The study was randomized, double-blind, and performed on the unpremedicated patients with ASA physical status I or II. Alfentanil was found to reduce the midazolam ED50 value for the induction of anesthesia in a dose-dependent fashion ...
Several alternative routes are currently being explored. This is a narrative review of data about delivery methods for benzodiazepines alternative to the intravenous and oral routes for the acute treatment of seizures. Unconventional delivery options such as direct delivery to the central nervous system or inhalers are reported. Data show that intranasal diazepam or midazolam and the intramuscular auto-injector for midazolam are as effective as rectal or intravenous diazepam. Head-to-head comparisons with buccal midazolam are urgently needed. In addition, the majority of trials focused on children and adolescents, and further trials in adults are warranted.. Reference:.

Drugs. Midazolam 2.5-5mg SC hourly PRN. Morphine 2.5-5mg SC 1-2 hourly PRN (higher doses of morphine may be appropriate in patients who are already receiving regular strong opioids. In patients who need repeated (hourly) doses seek specialist palliative care advice.) SeePalliation of Breathlessness and Symptom control in patients with renal disease and cardiac failure.. Patients who are persistently breathless and distressed may benefit from a continuous infusion of morphine and/or midazolam - in practice try to ascertain the required dose(s) by observing and titrating according to usage of morphine or midazolam over the previous 24-48 hours.. For some patients in the dying phase it may be more practical to commence an infusion of morphine or midazolam at an earlier stage alongside the provision of additional PRN medication.. ...
Results: 210 patients were included of whom 85 (40%) were given ketamine, 107 (51%) midazolam and 18 (9%) propofol. The median time to full orientation was 25 min for ketamine, 30 min for midazolam and 10 min for propofol. Complications occurred in 15.9% of sedations overall (14.6% of those given ketamine, 15.8% given midazolam and 22.2% given propofol). Apnoea and hypoxia most often occurred with midazolam and propofol, while hypertension and hypertonicity were encountered more frequently with ketamine. In addition, 19.5% of patients given ketamine suffered the re-emergence phenomenon. The association between deep sedation with no response to pain and adverse events encountered with midazolam does not occur with ketamine ...

In drug repositioning research, a new concept in drug discovery and new therapeutic opportunities have been identified for existing drugs. Midazolam (MDZ) is an anesthetic inducer used for general anesthesia. Here, we demonstrate the combined effects of bone morphogenetic protein-2 (BMP-2) and MDZ on osteogenic differentiation. An immortalized mouse myoblast cell line (C2C12 cell) was cultured in the combination of BMP-2 and MDZ (BMP-2+MDZ). The differentiation and signal transduction of C2C12 cells into osteoblasts were investigated at biological, immunohistochemical, and genetic cell levels. Mineralized nodules formed in C2C12 cells were characterized at the crystal engineering level. BMP-2+MDZ treatment decreased the myotube cell formation of C2C12 cells, and enhanced alkaline phosphatase activity and expression levels of osteoblastic differentiation marker genes. The precipitated nodules consisted of randomly oriented hydroxyapatite nanorods and nanoparticles. BMP-2+MDZ treatment reduced the

Great article and I hope that everyone who reads it will consider getting a colonoscopy. There is a TON of misinformation about colonoscopy, especially with the sedation drugs. My job involves a lot of international travel (I fly for a commercial airline) and my healthcare always takes a back seat to the rest of the things that I have to do. My primary care doc is always admonishing me to get a colonoscopy (FAP runs in my family and I could not be in a higher risk catagory for colon cancer) BUT I dont want to risk the long term memory-loss that sometimes occurs (rarely) with the sedation drugs such as midazolam (Versed). My neighbor is a nurse practitoner and she sustained some pretty serious and long-term memory loss after getting just 4mg of Versed for her colonoscopy and this is the most commonly used drug. Im not a doctor (although I did get accepted into med school before starting my current career); when I google "versed problems" I get a slew of credible horror stories about Versed and ...
Animal models have often been used to investigate the neurobiology of emotional states (fear and anxiety). In this sense, the elevated plus maze (EPM) and the rat exposure test are effective to evaluate these states and EPM exposure (aversive stimulus) can result in activation of serotonergic pathways with projections to structures belonging to the defense system, such as , amygdala, septum, hypothalamus, periaqueductal gray (PAG) and hippocampus. The hippocampus has a large amount of serotonin receptors (5- HT) and gamma-aminobutyric acid (GABA). In the present study, we used male mice of Swiss Albino, received surgical implantation of guide cannula and subsequent administration of drugs in the ventral hippocampus. After recovery, the animals were tested in EPM (Experiment 1 and 2) or the test exposure to the rat (Experiment 3 and 4). In Experiment 1, administration of midazolam (3.0 and 30.0 nmol) produced anxiolytic effect characterized by increased percentages of entries and time spent in ...
