ETHRANE vs PROPOFOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Enflurane is a volatile inhalational anesthetic that potentiates GABA-A receptor activity and inhibits excitatory neurotransmission, resulting in general anesthesia.
Propofol enhances the activity of gamma-aminobutyric acid (GABA) at GABA-A receptors, leading to increased chloride conductance, neuronal hyperpolarization, and anesthetic effects. It also inhibits N-methyl-D-aspartate (NMDA) receptors and modulates calcium influx via L-type calcium channels.
1-5% inspired concentration via inhalation, titrated to effect for maintenance of general anesthesia.
Induction: 2-2.5 mg/kg IV bolus. Maintenance: 25-75 mcg/kg/min IV infusion. For sedation: 25-100 mcg/kg/min IV.

Clinical Note
moderatePropofol + Torasemide
"The risk or severity of adverse effects can be increased when Propofol is combined with Torasemide."
Clinical Note
moderatePropofol + Etacrynic acid
"The risk or severity of adverse effects can be increased when Propofol is combined with Etacrynic acid."
Clinical Note
moderatePropofol + Furosemide
"The risk or severity of adverse effects can be increased when Propofol is combined with Furosemide."
Clinical Note
moderatePropofol + Bumetanide
Context-sensitive half-life: approximately 2-5 minutes after short procedures; prolonged after prolonged administration due to slow washout from fat stores.
Terminal elimination half-life: 4-7 hours (after prolonged infusion, context-sensitive half-life increases up to 60 minutes after 8-hour infusion).
Primarily exhaled unchanged via lungs (>95%); less than 5% metabolized in liver to fluoride ion and other metabolites, with renal excretion of metabolites.
Renal: <1% unchanged; hepatic metabolism to inactive glucuronide and sulfate conjugates, excreted renally (≈88%) and fecally (≈1-2%).
