Abstract

This study aims to determine that the test of medicines containing oxiracetam as their main ingredient was properly performed according to protocol. Furthermore, the study is to provide the written form of protocol in order to examine the validity of the HPLC analytical method for the quantitative analysis of oxiracetam in the finished products. In this experiment, system suitability, precision, linearity, range, accuracy, specificity, quantitative limit, and detection limit of the analytical method which was used to determine the contained quality of oxiracetam, were examined. The result shows that system suitability indicates 0.127% RSD, plate number 15081, tailing factor 0.49, and resolution 32.41. The experiment of precision reveals the result of below 0.359% for repetitiveness and among the subjects. In the linearity experiment, a coefficient of correlation ($R^2$) indicates that it is 1. The accuracy experiment satisfies the standards of the recovery test, which is minimum 98.4% and maximum 99.6%. Detection limit is 0.1 mg/L and quantitative limit was found to be 0.5 mg/L. The experiment to check the specificity also satisfies the standards, so the finished product using oxiracetam as the main ingredient is verified as suitable.

완제품의 주성분인 옥시라세탐이 함유된 의약품의 시험법실시 계획서에 따른 시험이 적절히 진행되었는지 시험법의 검증여부를 하고 본 protocol이 완제품 중 옥시라세탐의 정량분석을 위한 HPLC 분석법의 타당성을 검증하기 위한 문서화된 절차를 제공하는 것을 목적으로 한다. 본 실험에서는 옥시라세탐 함량시험에 사용된 분석법에 대하여 시스템 적합성, 정밀성, 직선성, 범위, 정확도, 특이성, 정량한계, 검출한계에 대하여 확인하였다. 실험결과 시스템적합성에서 정밀도(RSD%) 0.127%이하, 이론단수 15081, tailing factor 0.49, 그리고 분리능 32.41을 나타내었고, 정밀도실험에서는 RSD% 0.359% 이하의 결과를 보였다. 그리고 직선성 실험에서는 상관계수($R^2$)가 1을 나타내었고, 정확도 실험에서는 recovery test로서 최소 98.4%, 최대 99.6%로 기준을 만족하였다. 검출한계는 0.1 mg/L이였으며, 정량한계는 0.5 mg/L이었다. 그리고 특이성 실험에 있어서도 기준을 만족하는 결과를 나타내어 옥시라세탐을 주성분으로 하는 완제의약품 시험법은 적합한 시험법임이 검증되었다.
