Phenytoin (PHT) fine granule, which has the same bioavailability as the tablet, has recently been marketed. We projected a change of PHT dosage form from usual powder to fine granule. In view of the fact that 97% of PHT products prescribed and marketed are available in fine granules, 50% PHT preparations were produced in hospital pharmacy. 5 kinds of preparations using various lactoses as diluents were prepared and tested for their quality. Among them, the preparation from Aleviatin fine granule passing through a 42-mesh sieve and EFC lactose showed the best results in the mixing property and various sense tests. The change to this dosage form and its bioavailability tests were carried out by a cooperation of doctors and pharmacists. Serum PHT levels of all patients, assayed by EMIT method, showed a 20% to 30% increase after the administration of the new preparation (50% PHT fine granule with EFC lactose).

Pharmaceutical support systems for anti-neoplastic drug preparation for chemotherapy in hospital information systems are in need of improvement. With this in mind we developed a new support system in collaboration with system engineers (SEs) in January 2005. In the presentation of our requirements for the support system to the SEs, the most important part of the development process, we proposed a development model based on an end-user prototype system. The model comprised a five-step design and development of the prototype system through end-user computing, evaluation of the prototype system through actual use, the introduction of a step to determine the exact task requirements, detailed discussions with the SEs, and installation. Among the functions of the prototype system were support functions for the input of prescriptions, inventory management and task data assessment and a print-out function for record sheets. This model produced excellent results for the upgrade whose express purpose was the introduction of an end-user computing step. Furthermore, to evaluate the preparation support system, time-determinative factors involved in the preparation were analyzed and compared using data collected in November 2004 and March 2005. In the evaluation, two pharmacists dispensed a total of 791 and 1003 admixtures for 341 and 426 injection prescriptions, respectively, and the average preparation times were 18.15 and 15.43 minutes/prescription, respectively. Multiple regression analysis revealed several time-determinative factors with correlation coefficients of 0.803 and 0.668. The significant time-determinative factors were the number of vials, ampoules, and bottles for admixtures and the properties of drugs dispensed. The new system has resulted in improved patient safety and operational efficiency.
