Local transcutaneous delivery of non-steroidal anti-inflammatory drugs avoids gastrointestinal side effects and concentrates drugs in the intended tissues. An extraction and HPLC method was developed for ketoprofen in skin, fascia and muscle. Tissue samples were homogenized in NaHCO3. After methylene chloride removal of lipids, the aqueous layer was acidified with HCl and back extracted into isooctane/isopropanol. Ketoprofen was derivatized with ethylchloroformate/S-(-)-α-phenylethylamine in triethylamine, then detected by HPLC. Ketoprofen recovery was linear (1-33 μg/g) and was detected in these tissues following in vivo cathodic iontophoresis (160 mA*min). This represents the first non-radioactive method for determination of ketoprofen in tissues following transcutaneous iontophoresis.

In this diploma work is check possibility application indirect photometric detection for enantiomers separation lactic acids and beta-hydroxybutyric acid with capillary electrophoresis. As chiral selector is used vankomycin. Verifyed his ability partial separation lactic acid on antipode with using picric acid as vizualition anion in background electrolyte. Used was coated capillary. Application indirect photometric detection succeed. Chiral separation beta-hydroxybutyric acid wasn't successful. Hip roll by selection fit vizualization anions for purposes indirect photometric detection. Are measured their electrophoretic and spectrophotometric characteristics, for inquest compatibility use in capillary electrophoresis in relation to indirect photometric detection. From timed datums were to be you - nap optimal vizualizatin anions for others experimentation. According to ascertained and measured feature reflect be optimal eosine soluble in alcohol and bromophenol blue.
