One-dose packages are useful for managing complicated medication regimens for older patients. We experienced a case of Bayaspirin® tablet 100 mg (BA) and Micardis® tablet 40 mg (Mic 40) that were fused in a one-dose package at the time of medicine reconciliation. To our knowledge, there are no previous reports assessing the quality of these tablets caused by this physical incompatibility. Therefore, we aimed to examine this phenomenon and its impact on the drug compositions, as well as to identify the mechanisms.BA and Mic 40 in one-dose packages were stored at 30℃/75% relative humidity (RH) or 93%RH condition for 1 week. The stability evaluations were performed on appearance change, hardness, content, and dissolution rate. The active ingredients in each tablet were investigated to determine the mechanisms.Mic 40 showed changes in appearance and hardness, while BA showed a changed appearance, and reduced content and dissolution rate. The enteric coatings of BA and the additive in Mic 40 had an influence on the mechanism of incompatibility.Mic 40 contains meglumine, which is hygroscopic and deliquescent. Therefore, meglumine absorbs moisture and becomes a basic solution. Methacrylic acid copolymer LD dissolved in this basic solution results in adhesion with Mic 40 and leads to a decrease in both the content and the dissolution rate in BA. This is the first study to analyze the physical incompatibilities of enteric-coated aspirin tablets with non-coated telmisartan tablets in one-dose packages and provides useful information for clinical practice.

After an overdosing incident at our hospital,we developed an upper limit alert system that checks doses of injection drugs for individual patients as the physician uses the computerized order entry system.Based on each patient’s converted body surface area (BSA),the upper limit for an injection is estimated through comparison with the standard upper limit in a patient with a BSA of 1.6 m2.This is done automatically in accordance with a compensation formula provided by our hospital’s safety committee.Standard upper limits for each injection are based on past records of actual injection dosages administered in our hospital and discussion with clinical departments.When a physician tries to enter an order for an injection at a dose over the upper limit,the computer system issues the alert“non-enterable”and the order cannot be placed.In the case of a regimen for which there is a legitimate reason for using a dose higher than the upper limit,the physician must explain this to the pharmacist who will then unlock the alert system using a secret password that he or she has designated.Passwords are only valid for one day.As far as we know,this is the first computerized injection dosage upper limit alert system in the world.On doing a search of our database,we found that there had been 742 overdose alerts (0.47% of all injection prescriptions) during the 3 months following its introduction.Owing to the alerts,physicians altered 155 prescriptions (21.1% of all alerts).Our computerized alert system for checking injection dosages has proved to be very necessary in ensuring medication safety.

出版社版新規システム導入後のオーダシステム内の記録から,処方が試みられた併用禁忌の組み合わせなどを解析した.相互作用チェックは,その処方の投与期間内に重複しているすべての薬品を自処方内および他処方内の薬歴データファイルから抽出し,チェック対象薬剤が重複した場合,チェックメッセージを表示した.システム運用開始以降,13ヵ月間における処方せんおよび注射指示せんの枚数はそれぞれ290956枚,299017枚の計589973枚であった.調査期間内にチェックのかかった回数は299件であった.警告としたものを除く173件中,96件は処方が中止された.時間外の併用禁忌の処方の危険率は時間内に比べ実に4倍近くにも上った.オーダ別にみると,実に80%近くの併用禁忌の組み合わせは注射薬が関与するものであった.最もチェックのかかった頻度が高かった薬剤の組み合わせはトランサミン注とトロンビン細粒の組み合わせであった
