Dormicum Introduction

Dormicum is a benzodiazepine medication used to induce and maintain anaesthesia, aid in sedation for surgery or other medicinal procedures, and treat certain types of seizures, anxiety disorders, and insomnia. It is typically administered in intravenous, intramuscular, and oral form, and can cause drowsiness, confusion, and muscle relaxation depending on the dose.

Uses of Dormicum

  • Inducing and Maintaining Anaesthesia
  • Sedation during surgery or other medical procedures
  • Treatment of certain types of seizure disorders
  • Treatment of anxiety disorders
  • Treatment of insomnia

Mechanism of Action

Dormicum is a central nervous system (CNS) depressant that works primarily by activating the gamma-aminobutyric acid (GABA) receptor-chloride channel receptor complex. This interaction leads to increased chloride ion conductance, membrane hyperpolarization, and ultimately, the suppression of excitatory signaling. Additionally, it binds to benzodiazepine receptors which causes sedative, anxiolytic, and anticonvulsant activity.

How Long Does it Take to Work?

The effects of midazolam can occur within minutes as it is rapidly and readily absorbed. Intestinal absorption is higher when it is injected intravenously compared to the intramuscular route.

Absorption

Dormicum is rapidly and readily absorbed when administered orally, intravenously, or intramuscularly. Intestinal absorption is higher when it is injected intravenously compared to the intramuscular route.

Route of Elimination

Dormicum is rapidly metabolized in the liver by cytochrome P450 enzymes and subsequently excreted by the kidneys in the form of metabolites.

Dosage

The dosage of midazolam is variable and depends on the patient's age, size, indication, route, and desired effects. When administered orally, typical adult dosages range from 0.5 mg to 6 mg taken two to three times daily. Intramuscular and Intravenous dosing typically ranges from 0.25 mg to 5 mg depending on the desired effect.

Administration

  • Headache
  • Sleepiness
  • Nausea
  • Blurred vision
  • Restlessness
  • Confusion
  • Muscle weakness
  • Drowsiness

Toxicity

Overdose of midazolam can be lethal as it can cause respiratory depression, hypotension, coma, and death. The risk of toxicity increases in cases of existing liver or kidney impairment, polymedication, and when other drugs are taken in conjunction with midazolam.

Precaution

  • Dormicum should not be taken with alcohol, other benzodiazepines, opioids, or other CNS depressants.
  • Dormicum should not be taken if the individual is pregnant or nursing.

  • Incompatible drugs to be avoided include, but are not limited to, monoamine oxidase inhibitors (MAOIs), tricyclic antidepressants, some antihistamines and alcohol.
  • Monitoring is recommended when taking midazolam with antiepileptic drugs (AEDs) or other drugs that affect liver enzyme activity.
  • Some drugs may increase the effects of midazolam, including certain antibiotics, antifungals, antipsychotics, calcium channel blockers, and certain antivirals.

Disease Interactions

  • Liver or kidney dysfunctions can increase the chances of experiencing adverse effects.
  • Breathing disorders can lead to the accumulation of midazolam in the body and increase its sedative effects.
  • Psychiatric disorders, including depression or suicidal thoughts, can increase the risk of addiction and other serious side effects.
  • Dormicum should be used with caution in individuals with mitochondrial disorders.

Drug Interactions

Dormicum interacts with many other drugs and can cause additive CNS depressant effects. Drugs such as opioids, benzodiazepines, antifungals, antipsychotics, calcium channel blockers, and certain antivirals may increase the sedative effects of midazolam. When combined with antiepileptic drugs (AEDs) or other drugs that affect liver enzyme activity, monitoring is recommended.

Food Interactions

Dormicum does not interact with food, but it may take longer to take effect if taken with food.

Pregnancy Use

Dormicum should not be taken by pregnant women due to the risk of teratogenic effects. Its safety has not been established for lactation. It should be avoided in women who are breastfeeding.

Lactation Use

Dormicum should not be taken by lactating women due to the risk of teratogenic effects. Its safety has not been established for lactation. It should be avoided in women who are breastfeeding.

Acute Overdose

Acute overdose of midazolam increases the risk of coma, respiratory depression, hypotension, and death. Supportive measures and symptomatic treatment should be initiated promptly. Forced diuresis, dialysis, exchange transfusion, and hemodialysis are not expected to be effective in removing the drug from the body.
