title: Testing of decomposition of pyridinedicarboxylic acid derivatives in selected pharmaceutical preparations.
abstract: Decomposition of nifedipine in Adalat tabl. and Cordafen drops and nitrendipine in Nitrendipine tabl. preparations under influence of UV radiation operation and temperature of 50 degrees C was tested. Chromatographic methods of TLC and HPCL and spectrophotometry were used for evaluation of the decomposition processes.
