These levels may become significant if doses of thiopental are repeated, causing large amounts to be stored in fat. Thus, storage in fat initially shortens the drug’s effect but then prolongs it.
WebThe role of metabolism becomes more relevant after repeated administration of high doses of thiopental in neurotraumatology. Thiopental is almost completely biotransformed in the liver to mostly inactive metabolites, which are then excreted in the urine. Drug metabolism usually occurs in the liver, but occasionally can take place in the … By definition, a drug administered intravenously undergoes immediate and … Drug or drug metabolites must be hydrosoluble to be excreted in the urine. … This prolongs the drugs half-life and may produce undesired accumulation. But is … “Rate of plasma drug removal by an organ of elimination, divided by the rate at … First-order elimination kinetics : For first order elimination, the plasma … “Part of the total clearance due to liver enzyme activity and biliary excretion” … Sodium thiopental is an ultra-short-acting barbiturate and has been used commonly in the induction phase of general anesthesia. Its use has been largely replaced with that of propofol, but may retain some popularity as an induction agent for rapid-sequence induction and intubation, such as in obstetrics. Following intravenous injection, the drug rapidly reaches the brain and causes unconsciousness within 30–45 seconds. At one minute, the drug attains a peak concentration o…

Large doses cause electrical … Web8 feb. 2024 · Once reconstituted, thiopental has a pH between 9 and 10, which is caustic if administered perivascularly. The high alkalinity of the solution results in thiopental having a long shelf life, but as the solution ages it becomes less potent (Thurmon et al., 1996).
WebThe half-life was approximately doubled. A moderate reduction in induction dosage requirements of thiopental (about 15%) has been noted following use of intramuscular midazolam for premedication in adults. The intravenous administration of midazolam decreases the minimum alveolar concentration (MAC) of halothane required for general …
