What drug class is brevital?
Controlled Substance—BREVITAL is a Schedule IV drug. BREVITAL may be habit-forming. The onset of toxicity following an overdose of intravenously administered methohexital will be within seconds of the infusion. If methohexital is administered rectally or is ingested, the onset of toxicity may be delayed.
What is the mechanism of action of propofol?
The action of propofol involves a positive modulation of the inhibitory function of the neurotransmitter gama-aminobutyric acid (GABA) through GABA-A receptors. Rapid – time to onset of unconsciousness is 15-30 seconds, due to rapid distribution from plasma to the CNS.
Why is brevital ultrashort acting?
Methohexital (Brevital) is a short-acting barbiturate for IV induction of anesthesia (1–2 mg/kg). Administered intravenously as a 1% solution (10 mg/mL), it produces pain at the injection site; hiccups, apnea, and seizure-like activity may also be occasionally observed.
What is brevital used for?

What kind of anesthesia is used for ECT?
Methohexital is most commonly used and is the preferred anesthetic for ECT because of its established safety record, effectiveness, and low cost. Propofol, while an effective induction anesthetic, has the greatest anticonvulsant properties of commonly used agents for ECT.
Can brevital cause respiratory depression?
Prolonged administration may result in cumulative effects, including extended somnolence, protracted unconsciousness, and respiratory and cardiovascular depression. Respiratory depression in the presence of an impaired airway may lead to hypoxia, cardiac arrest, and death.
How do you dilute brevital?
For continuous drip anesthesia, prepare a 0.2% solution by adding 500 mg of Brevital Sodium to 250 mL of diluent. For this dilution, either 5% glucose solution or isotonic (0.9%) sodium chloride solution is recommended instead of distilled water in order to avoid extreme hypotonicity.
What kind of sodium is in Brevital sodium?

Methohexital sodium for injection is a freeze-dried, sterile, nonpyrogenic mixture of methohexital sodium with 6% anhydrous sodium carbonate added as a buffer. It contains not less than 90% and not more than 110% of the labeled amount of methohexital sodium.
What are the side effects of taking Brevital?

Where does the excretion of Brevital take place?
Excretion occurs via the kidneys through glomerular filtration. BREVITAL can be used in adults as follows: 1.For intravenous induction of anesthesia prior to the use of other general anesthetic agents.
What kind of metabolites are found in Brevital?
