Thiopental Sodium C화학적 특성, 용도, 생산
화학적 성질
Yellowish-white, hygroscopic powder.
용도
Pentothal (Abbott).
정의
A rapidly acting barbiturate administered
intravenously for general anesthesia and hypnosis.
Commonly known as “truth serum.”
위험도
May cause respiratory failure; use onlywith
physician in attendance.
Pharmacokinetics
Thiopental is highly bound to albumin, and free drug availability is increased
in hypoproteinaemia. Protein binding is decreased by alkalaemia,
hyperventilation and some drugs that occupy the same albumin binding
sites, thereby increasing unbound thiopental concentrations. Metabolism
occurs predominantly in the liver, and the metabolites are excreted by the
kidneys. Only a small proportion is excreted unchanged in the urine. The
terminal elimination half-life is approximately 11.5h (longer in the elderly).
Elimination after an infusion is a zero-order process with 10%–15% of the
remaining drug metabolised each hour. Up to 30% of the original dose may
remain in the body at 24h, and a hangover effect is common. Accumulation
may result if further doses of thiopental are administered within 1–2 days.
Safety Profile
Poison by ingestion, intraperitoneal, rectal, subcutaneous, and intravenous routes. Human systemic effects by intraarterial route: acute arterial occlusion; by rectal route: respiratory depression, body temperature decrease, general anesthetic. An experimental teratogen. Experimental reproductive effects. An intravenous anesthetic. When heated to decomposition it emits toxic fumes of NO, and Na2O. See also PENTOTHAL and BARBITURATES
