However, it is important to know that inappropriate use of this drug and long-term use of it causes dangers to health. This product has a high potential for misuse, abuse, dependence, and addiction. In this article, information about the product’s category, dosage, mechanism of action, side effects, dangers, and overdose treatment options will be provided.

What is Midazolam?

Classified under the group Benzodiazepines, this drug is used as anesthesia and as an emergency treatment for seizures. It is the generic name of Dormicum, Hypnovel, and Versed. Also, this medication is considered a prescription drug. Compared to other prescription drugs, Benzodiazepines are highly addictive and are prone to be misused and abused. These medicines are listed as Essential Medicines by the World Health Organization. Since it is a very powerful one, it is also considered as a controlled substance. Thus, it should be used only in hospital or ambulatory care settings.

Midazolam Dosage Forms and Strengths

To identify the dosage form and strength to be used, a physician considers the age and weight of the patient. Thus, Midazolam uses are always determined by the doctor.

The Medication Is Available In the Following Dosage Forms and Strengths: 

  • Syrup (2mg/mL)
  • Tablet (15mg)
  • Nasal spray (0.5mg, 1.25mg, and 5mg/mL)
  • Injection (5mg/mL, 5mg/5mL, and 15mg/3mL)

Aside from the age and weight, the dosage form and strength to be used will also depend on a patient’s health and condition. For example, an older patient might be prescribed a syrup if the patient is unable to swallow tablets.

Benzodiazepines Mechanism of Action

Like the other Benzodiazepines, this anesthesia binds with the GABA receptor in the brain. For the brain to function properly, inhibition and excitation should be balanced and this balancing activity is done by the GABA receptor. When the drug is bound with the GABA receptor, there will be a promotion of sleep because the former will help the receptor to focus more on its inhibiting activity. Eventually, the benzodiazepine will cause muscle-relaxing effects after acting on glycine receptors in the brain.
