Packaging: Storage:. In order to avoid the development of drug dependence at course treatment duration Phenazepam application is 2 weeks (in some cases the duration of treatment can be increased up to 2 months). If you cancel Phenazepam reduce the dose gradually.

Suggested Use:. Treatment: gastric lavage, activated charcoal. Hemodialysis - is ineffective. Symptomatic therapy (maintenance of respiration and blood pressure), administration of flumazenil (in the hospital).

Sedation due to the influence on the reticular formation of the brain stem and the nonspecific thalamic nuclei and manifested a decrease in symptoms of neurotic origin.

In severe agitation, fear, anxiety, treatment is initiated with a dose of 3 mg / day, quickly increasing the dose to produce a therapeutic effect.

The maximum daily dose - 10 mg.

Anticonvulsant action is realized by increasing presynaptic inhibition suppresses the spread of seizure pulse, but does not eliminate the excited state of the hearth.

It stimulates benzodiazepine receptors located in the allosteric center of postsynaptic GABA receptors ascending activating reticular formation of the brain stem; reduces the excitability of the subcortical structures of the brain (the limbic system, thalamus, hypothalamus), polisinapticheskie inhibits spinal reflexes.

All benzodiazepines share a common chemical structure, shown in Fig.. peak effects of sedative and anticonvulsant activity are distinctly different for each drug and among drugs, Diazepam, midazolam, and lorazepam all appeared rapidly in the CSF Synthesis and structure-activity relationship studies in peripheral.

Over the intervening years, the number of benzodiazepines has increased, with each new drug demonstrating unique and complex pharmacology. 74 ). 17 The search for better sedatives with fewer side effects led to the development of barbiturates in the early 1900s followed by numerous others such as meprobamate, glutethimide, and ethchlorvynol ( Chap.

The main effects of benzodiazepines are sedation, hypnosis, decreased anxiety, anterograde amnesia, centrally mediated muscle relaxation and anti-convulsant activity. The four benzodiazepines, widely used in clinical anaesthesia, are the agonists midazolam, diazepam and lorazepam and the antagonist flumazenil.

Midazolam

Structure activity relationship of diazepam and midazolam

The free base (closed-ring structure) is the active form; it is highly lipid structure-activity relationships - ionised (water-soluble), unionised (lipid of midazolam, chlordiazepoxide, and diazepam displace the binding of.

The drug is in the open-ring form. Midazolam for injection is supplied as the hydrochloride salt and the pH of the solution is adjusted to 3. After injection into the blood (typical pH 7.4), the lipid-soluble closed ring structure reforms.

incl VD, plasma protein binding, tissue affinities.

Regarding midazolam and use as part of subarachnoid or epidural blocks, and related to an IV Anaesthetics MCQ in Feb 2006, midazolam is not active at mu receptors, but may be active at delta and kappa receptors as an agonist.

Its major uses in anaesthetic and intensive care practice are:

Midazolam is a imidazobenzodiazepine which has a pH-dependent structure.

Major side-effects include hypotension, apnoea, airway obstruction and loss of protective airwary reflexes. Midazolam is the only clinically available water-soluble benzodiazepine and is commonly used as intravenous sedative or anaesthetic. The water solubility of this imidazobenzodiazepine is dependent on a pH-dependent change in structure.

It is not much used for induction of general anaesthesia because of its slow onset and slow offset compared to alternatives (eg thiopentone, propofol ). Its advantage over these alternatives is cardiorespiratory stability.

In an in vitro functional assay, midazolam is a weak agonist at the delta-opioid receptor, whereas all three benzodiazepines are kappa-opioid agonists. These findings may partially explain the mechanism of benzodiazepine-induced spinal analgesia." (1) recent research. Our results show that large concentrations of midazolam, chlordiazepoxide, and diazepam displace the binding of -diprenorphine-an opiate radioligand from kappa receptors. "Midazolam was also weakly active at delta-receptor activation, whereas all three were inactive at mu receptors." (1) "Several human and animal studies have shown analgesic effects of benzodiazepines after spinal injection.
