Clobazam (7-Chloro-1-methyl-5-phenyl-1,5-benzodiazepine-2,4(3H)-dione) an anticonvulsant drug used since 1984, with molecular formula C16H13ClN2O2 and molecular mass 300, was characterized with sophisticated instruments like FTIR, UV-NIR, GC-MS, TGA-DTA-DSC and Nano particle size analyzer with zeta potential. The compound was confirmed with the help of GC-MS and the mass of sample was found aggregate with the standard values and mass spectra compare with NIST and WELEY library data. The UV-NIR analysis showed that the λmax was 231 nm with methanol as a diluent. FTIR analysis of the Clobazam gave the characteristics peaks of cyclic amide. HPTLC was used to determine the purity of the drug. Thermal behavior was studied with TGA-DTA-DSC analysis. The particle size of clobazam was measured with the Nano particle size analyzer and Zeta potential of drud found -77.0 mV. The purity of drug check with Preparative HPLC system.

Application of electrochemical sensors in determination of selected drugs

Precise and cheap methods for fast detection of drugs for the purposes of administration of appropriate medication are of paramount importance in clinical practice. Nowadays, many pharmaceutics with a high toxicity and narrow margin of safety are applied, so they should be delivered very precisely. Electrochemical methods have been used to determine the concentration of benzodiazepines, phenothiazines and paracetamol types of drugs. These drugs were widely tested, and their electrode reactions, dependences on the medium parameters and metabolism are known. These data may be the basis for the development of biosensors for the above mentioned drugs.
