Lercanidipine distribution in warm-blooded animals
THE AIM OF THE STUDY: Is to investigate the lercadipine distribution in warm-blooded animals (rats). The experimental study used rats of Wistar race. TLC, GC-MS and UV-spectrophotometry methods were used for physical and chemical analysis. Semilethal (890 mg/kg) dose of lercadipine, previously suspended in water, was injected into stomach of laboratory animals. Examined substance was isolated from the thick tissues and animals' blood by acetone, cleaned with a change of solvent and macrocolumn chromatography using 30 µm «Silasorb S-18» sorbent and acetonitrile-water (8:2) polar eluent. The analyte was identified by chromatographic behavior in the thin sorbent layer, retention time and set of positive ions in its mass spectrum, as well as by UV-spectrum. The analyte was determined quantitatively in bioactive matrix using UV-spectrophotometry. The methods were validated by criteria of linearity, selectivity, accuracy, precision, detection limits and quantitative determination. The main content of lercanidipine (mg/100 g) was determined in the stomach content (198.183±29.541), the stomach (195.312±21.579), the small intestine (47.096±3.947), the spleen (38.952±3.532) and the liver (26.211±2.232).
