FIELD: medicine.
SUBSTANCE: invention relates to field of medicine and can be applied in control-analytic laboratories for standardisation and control over medication quality. Method deals with determination of drotaverine hydrochloride by spectrophotometry of determined substance and standard sample of comparison, as solvent for preparation solution to be determined applied is 0.1 M solution of hydrochloric acid, concentration of analysed solution constitutes 0.000017 g/ml, as comparison, sample potassium dichromate is applied, value of conversion rate 0.434 is introduced into formula for calculation of results and calculation is performed by formula.
EFFECT: method makes it possible to increase reproducibility of determination results, reduce cost, labour consumption, analysis error, to unify analysis methodology.
