  • We developed an alternative assay method without hazardous reagent of chloroform for urazamide tablets in Korean Pharmaceutical Codex. The HPLC analytical method was validated by system suitability, linearity, precision, accuracy and robustness. The linearity of the calibration curves in the desired concentration range is good ($r^2$ >0.999). Precision was obtained less than RSD 1.17%. Accuracy was obtained with recoveries in range of 98.12% and 99.47%. The developed assay could be expected to become valuable tools for revising the Korean Pharmaceutical Codex.

  • Currently nonaqueous titration method for the assay method using the hazardous reagent, mercury acetate for difemerine hydrochloride has been used in Korean Pharmaceutical Codex. We developed an alternative titration assay method by substituting the use of the hazardous reagent, mercury acetate to the use of less toxic ones like ethyl alcohol. The linearity of the calibration curves in the desired concentration range was good (r>0.999). Precision was less than 0.64%. Accuracy was obtained with recoveries in range of 99.10% and 99.71%. The developed assay could be expected to become valuable tools for revising the Korean Pharmaceutical Codex.

  • Development of alternative testing methods for the replacement of hazardous reagents with less hazardous ones is strongly enforced because exposure of human and environment to hazardous reagents are restricted and hazardous reagents are gradually prohibited from using in various testing methods. Thus, in this study, we developed 8 monographs from the Korean Pharmaceutical Codex by substituting the use of the hazardous reagents including ICH class 1 such as benzene, chloroform and dioxane to the use of less toxic ones like ICH class 2 or 3 reagents. We also improved their qualification and quantification performance. Among 8 monographs, the 6 newly developed TLC methods for the identification of nifedipine, oxolamine citrate, ketoprofen lysinate, chlorquinaldol, retinol acetate, and riboflavin showed a clear spot of corresponding material without any interference in spite of the replacement with ICH class 2 or 3 reagents. For the quantification of domperidone and trimebutine, HPLC methods were developed for the substitution of UV/VIS spectrometry and titrimetry, respectively. These HPLC methods were validated for the linearity, recovery, reproducibility, and inter-laboratory variations. In conclusion, the newly developed methods could be expected to become valuable tools for revising the Korean Pharmaceutical Codex.

  • Currently oxidation-reduction titration method for the assay method using the hazardous reagent, carbon tetrachloride, for cefroxadine capsules has been used in Korean Pharmaceutical Codex. We developed and validated an alternative HPLC assay method by substituting the use of the hazardous reagent, carbon tetrachloride, to the use of less toxic ones like acetonitrile. The linearity of the calibration curves in the desired concentration range was good ($r^2$ > 0.999). Relative standard deviations of intra-day precision were ranged between 0.30% and 0.69% and inter-day precision were ranged between 0.47% and 0.82%. Accuracy was obtained with recoveries in range of 100.20% and 100.56%. Developed method was applied to the determination of cefroxadine in commercial cefroxadine capsule and could be expected to become valuable tools for revising the Korean Pharmaceutical Codex.

  • The aim of publishing the Korean Pharmaceutical Codex is to update and set specification of essential drugs for humane health. In accordance with speedy development of new drugs and improvement of science and technology, the need of revision of drug specification through the ICH guidelines and discussions between regulatory agency and pharmaceutical industry for the quality assurance of safer and efficient drugs is getting higher. The first edition of Korean Pharmaceutical Codex was published in 1983. Now, the third revision of the Codex is prepared because of the revision of domestic and foreign Pharmacopeias, changes of drug control environment, improvement of science and technology and so on. The aim of 3th edition is to improve the quality of essential drugs through the setting of the required specifications and discussions between the regulatory agency and pharmaceutical industry.

  • The Korean Pharmaceutical Codex (KPC) analytical method of ambroxol hydrochloride and clenbuterol hydrochloride formulation is complicated and needed to carry out multiple processes during the test. To improve the low efficiency of analytical procedure that makes pharmaceutical laboratory consume much time and high cost to conduct the test of this formulation, this study was performed for simplifying the pretreatment process and optimizing conditions of the HPLC assay. The analytical procedure using HPLC was developed to establish analytical specification for ambroxol hydrochloride and clenbuterol hydrochloride formulations. The newly developed analytical method has good linearity ($R^2$ >0.999), specificity, precision (RSD<1.0%) and the recovery ranges of 98.50~101.84% for ambroxol, 98.29~101.35% for clenbuterol syrup and 98.66~101.71% for clenbuterol tablets. The LOQs were 0.204 ${\mu}g/ml$ for ambroxol, 0.021 ${\mu}g/ml$ for clenbuterol syrup and 0.073 ${\mu}g/ml$ for clenbuterol tablets. The new method was performed with commercially available samples to confirm analytical conditions and validated to be suitable for saving time and cost to control the quality of routine manufactured products. This analytical method will be used for revising the monograph of ambroxol hydrochloride and clenbuterol hydrochloride formulation in next supplement of KPC.

  • Although the dissolution test can serve as an effective tool for quality control and predictor of in vivo performance, there are a number of drugs with no established dissolution specification in Korean Pharmaceutical Codex (KPC). So, with each reference and test drugs, the dissolution test method and an analytical procedure by HPLC were developed and validated to establish dissolution specification for acebrophylline capsules and bromhexine hydrochloride tablets. The dissolution condition was determined based on the "Guidelines on Specifications of Dissolution tests for Oral dosage forms" of Ministry of Food and Drug Safety (MFDS). The analytical method of HPLC was validated in specificity, linearity, precision and accuracy. Final dissolution test was performed with commercially available samples of 3 lots to establish specification. In addition, no difference was observed by the inter-laboratory evaluation. Dissolution specifications and conditions will be used for revising the monograph of acebrophylline capsules and bromhexine hydrochloride tablets in next supplement of KPC.

  • Although the dissolution test can serve as an effective tool for quality control and predictor of in vivo performance, there are a number of drugs with no established dissolution specifications in Korean Pharmaceutical Codex (KPC). Among those commercially available, Piracetam Tablets and Fenoterol hydrobromide Tablets were selected to develop the dissolution testing method. The dissolution condition was determined based on the "Guidelines on Specifications of Dissolution tests for Oral dosage forms" of Korea Food & Drug Administration (KFDA). The dissolution test for Piracetam Tablets was carried out under sink condition with distilled water as dissolution medium, paddle rotation speed at 50 rpm and medium volume of 900 ml. More than 80% of its label claim was released within 30 min. In case of Fenoterol hydrobromide Tablets, distilled water was also found to be suitable to ensure sink condition. The rotation speed of 50 rpm and 900 ml of dissolution medium were used to evaluate the dissolution profile. The dissolution rate of fenoterol hydrobromide was over 90% in 15 min. The HPLC analysis methods were validated in terms of accuracy, precision, specificity, linearity, quantitation limit and range. The results suggested that the analytical methods used are simple and suitable to measure the dissolution rate of piracetam and fenoterol hydrobromide. Therefore, the analysis methods could be utilized in setting dissolution specifications of Piracetam Tablets and Fenoterol hydrobromide Tablets in the revised version of KPC.
