What is midazolam injection? How does midazolam work?

Midazolam is a drug used for sedation. It is in the benzodiazepine family, the same family that includes lorazepam (Ativan), diazepam (Valium), alprazolam (Xanax), clonazepam (Klonopin), flurazepam (Dalmane), and others. It is thought that excessive activity of nerves in the brain may cause anxiety and other psychological disorders. Gamma-aminobutyric acid (GABA) is a neurotransmitter, a chemical that nerves in the brain use to send messages to one another. GABA reduces the activity of nerves in the brain. Midazolam and other benzodiazepines may act by enhancing the effects of GABA in the brain. The FDA approved midazolam in December 1985.

Midazolam is given by intramuscular or intravenous injection. The dose for sedation during surgery is 0.5 to 1 mg given over 2 minutes and not to exceed 2.5 mg per dose. Doses may be repeated after 2 to 3 minutes. Total doses greater than 5 mg usually are not needed. The dose for starting anesthesia is 200 to 350 mcg/kg injected intravenously over 20 to 30 seconds.

Which drugs or supplements interact with midazolam?

Midazolam and all benzodiazepines interact with other medications and drugs that slow the brain's processes such as alcohol, barbiturates, narcotics, and tranquilizers. Boceprevir (Victrelis), itraconazole (Sporanox), nelfinavir (Viracept), and telaprevir (Incivek) increase blood level of midazolam by reducing its breakdown in the liver and, therefore can increase the side effects of midazolam.
