AMIDATE vs PROPOFOL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
AMIDATE (etomidate) is a nonbarbiturate hypnotic agent that acts as a positive allosteric modulator of the GABA-A receptor at the beta-2/3 subunit, enhancing the inhibitory effects of GABA and producing rapid sedation and 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.
0.2-0.6 mg/kg IV bolus for induction of 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.

Terminal elimination half-life: 2.5–4 hours (adults); 1–2 hours (children); Prolonged in hepatic impairment or with continuous infusion.
Terminal elimination half-life: 4-7 hours (after prolonged infusion, context-sensitive half-life increases up to 60 minutes after 8-hour infusion).
Renal: <5% unchanged; Hepatic metabolism to carboxylic acid metabolite (inactive); Metabolite renally eliminated; Fecal: negligible.
Renal: <1% unchanged; hepatic metabolism to inactive glucuronide and sulfate conjugates, excreted renally (≈88%) and fecally (≈1-2%).
