Description
Propofol is an intravenous anaesthetic agent used for induction and maintenance of general anaesthesia. IV administration of propfol is used to induce unconsciousness after which anaesthesia may be maintained using a combination of medications. Recovery from propofol-induced anaesthesia is generally rapid and associated with less frequent side effects (e.g. drowsiness, nausea, vomiting) than with thiopental, methohexital, and etomidate. Propofol may be used prior to diagnostic procedures requiring anaesthesia, in the management of refractory status epilepticus, and for induction and/or maintenance of anaesthesia prior to and during surgeries.
Indication
Used for induction and/or maintenance of anaesthesia and for management of refractory status epilepticus.
Mechanism of Action
The action of propofol involves a positive modulation of the inhibitory function of the neurotransmitter gama-aminobutyric acid (GABA) through GABA-A receptors.
Pharmacokinetics
- Absorption
- Rapid - time to onset of unconsciousness is 15-30 seconds, due to rapid distribution from plasma to the CNS. Distribution is so rapid that peak plasma concentrations cannot be readily measured. Duration of action is 5-10 minutes.
- Distribution
- * 60 L/kg [healthy adults]
- Metabolism
- Hepatically metabolized mainly by glucuronidation at the C1-hydroxyl. Hydroxylation of the benzene ring to 4-hydroxypropofol may also occur via CYP2B6 and 2C9 with subsequent conjugation to sulfuric and/or glucuronic acid. Hydroxypropofol has approximately 1/3 of hypnotic activity of propofol.
- Elimination
Clearance
* 23 - 50 mL/kg/min * 1.6 - 3.4 L/min [70 Kg adults]
Toxicity
Overdosage may increase pharmacologic and adverse effects or cause death.
IV LD50=53 mg/kg (mice), 42 mg/kg (rats). Oral LD50 (as a solution in soybean oil)=1230 mg/kg (mice), 600 mg/kg (rats)
