[An analytical study of 2 dimethylxanthine derivatives with action at the level of the cardiovascular system]

The analytical investigation of two derivatives of dimenthylxantine series, conventionally termed Imfilin and Carprofilin, is presented. For the quantitative determination of these derivatives the authors suggest spectrophotometric methods in UV which gave good results in the physicochemical control of the substances and of certain pharmaceutical forms (injectable solutions, tablets). The suggested methods were applied in observing the stability of these pharmaceutical forms as well as in their determination in the biological material.
