The evaluation of validation parameters gives evidence about possibility of application of refractometric method in the conditions of drugstores for the quality control of preparation of this solution according to the modern requirement. But it is possible under the condition either widening limits of content active substance until 10 % or using of refractometric technique whit the bound of acceptable error of refractive index not above п<sub>D</sub> — ± 1 · 10<sup>-4</sup>.</p&gt;}, number={6}, journal={Farmatsevtychnyi zhurnal}, author={Yevtifeyeva, O.A. and Goryunova, O.V.}, year={2019}, month={Oct.}, pages={72-77} }
