Trichloroethylene is a volatile chlorinated organic solvent that has been used historically as an inhalation anesthetic and analgesic agent but is now primarily employed in industrial applications as a degreasing solvent. Due to concerns about toxicity, carcinogenicity, and safer alternatives, medical use in anesthesia has been discontinued in most countries.
Pharmacokinetics
Pharmacokinetic parameters reported in healthy adult human volunteers following single inhalation exposure.
