After meropenem hydrate (MEPM) injection and amino acid infusions are mixed, the MEPM residual ratio sequentially decreases. This incompatibility is probably due to the nucleophilic attack on the β-lactam ring of MEPM by L-cysteine (L-Cys) present in the amino acid infusion. This study aims to identify the influence of L-Cys on the reaction between MEPM injection and amino acid infusions through an initial incompatibility test between MEPM and L-Cys at pH 4 to 8, followed by an incompatibility test between MEPM injection (MEPM plus additives) and 18 types of amino acid infusions. In the MEPM and L-Cys incompatibility test, as the pH increased, the MEPM decomposition speed was observed to increase after mixing of the two components. This reaction progressed as a secondary reaction, the linear relationship between pH and the logarithm of secondary reaction speed constant, k2, was established (ln k2 = 1.632 × pH - 15.631, r2 = 0.998). In the incompatibility test between MEPM injection and amino acid infusions, as the concentration of L-Cys increased, the MEPM residual ratio was observed to decrease. At 10 and 30 minutes after the mixture of components, a strong correlation was observed between the estimated MEPM residual ratio from the reaction velocity and the measured value (10 minutes: r2 = 0.985, RMSE: 5.44%; 30 minutes: r2 = 0.986,RMSE: 4.55%). The results above indicate that the residual ratio of MEPM obtained through the L-Cys incompatibility test matches the measured residual ratio of MEPM using the MEPM injection and amino acid infusions. Therefore, L-Cys has been identified as the main cause of incompatibility between MEPM injection and amino acid infusions.

Objective: In this study, we evaluated to examine the short-term educational effects for drug abuse prevention, including lectures and students’ awareness of drug abuse.Method: A questionnaire consisting of eleven items and SD method-based image survey were conducted three times, prior to and following the lectures and after the summer vacation for first-year students of the Department of Pharmacy.Results: The numbers of responses to the questionnaire surveys conducted prior to and following the summer vacation were 323 (response rate: 95.8%) and 332 (response rate: 97.9%), respectively.  When asked: “Do you think that people should be allowed to use cannabis (illegal herbal drugs) as long as they do not cause any trouble to others”, 2.8 (3.4) and 6.9 (6.6)% of students answered “Yes” after the lectures prior to the summer vacation and following it, respectively; there were both increased.  Following the summer vacation, 28.6% of students answered “Yes” to the question: “Have you ever seen or heard of people using cannabis or illegal herbal drugs ?”  A total of 2.1% of students had been “solicited to use cannabis or illegal herbal drugs”, and all of them stated that it would be “easy to obtain illegal herbal drugs”.  As the reason for drug abuse by young people, 140 students (42.2%) cited “curiosity”, and 81.6%, or 271 students, stated that they would “refuse” to use any illegal drugs even if they were asked to do so.  The results of the SD method-based image survey suggested significant changes in students’ awareness of drug abuse during the summer vacation; they had the image of little risk on drug abuse prevention following the vacation.Conclusion: The effects of learning were not maintained in some first-year students because they faced a variety of temptations during the short summer vacation and their normative consciousness and images of drug abuse easily changed.  Therefore, it is necessary to provide lectures for new students to help them acquire accurate knowledge of drug abuse, enhance their normative consciousness, and increase their self-awareness as health care professionals, develop curriculums on a continuing basis, and deploy specialists so that students with psychological problems as identified by the survey, including stress, escapism, mental weakness, and anxiety, can consult them.
