[Toxicologic analysis of some adrenergic-beta blockers in the diagnosis of intoxications].

The study aimed at finding effective techniques of qualitative and quantitative analysis of selected beta-adrenergic blockers, useful both for monitoring of therapy and for thanatological diagnosis of intoxications. The studies took advantage of gas chromatography (GLC) and high performance liquid chromatography (HPLC). For isolation of studied compounds from biological material, classical and solid phase extraction procedures (SPE) Extrelut-20 (Merck), Abselut Nexus (Varian), STRATA C--18 E (Phenomenex) were used. The program included the analysis of most frequently applied derivatives: Acebutolol, Atenolol, Bunitrolol, Bupranolol, Labetolol, Metipranolol, Metoprolol, Oxprenolol, Practolol, Propranolol.
