ABSTRACT
This study is aimed at evaluating effective techniques of qualitative and quantitative analysis of selected 1,4-dihydropyridine calcium channel blockers, useful both for thanatological diagnosis of intoxications as well as monitoring therapy. The studies took advantage of gas chromatography (GLC) and high performance liquid chromatography (HPLC). Isolation of studied compounds from biological material was performed using classical and solid phase extraction procedures (SPE) such as Bond Elut LRC (Varian), Abselut Nexus (Varian), STRATA C - 18 E (Phenomenex). The program included analysis of nine of the most frequently prescribed derivatives: nifedipine, felodipine, amlodipine, nicardipine, nimodypine, nilvadipine, nitrendipine, nisoldipine, isradipine.

We reported the first case of accidental or intentional overdose with isradipine. A 2 y-old male accidentally ingested 2.5 mg of isradipine. A drop in arterial pressure responded to fluids. No other symptoms were noted. The child recovered without sequelae.
