A 0.625% povidone-iodine solution (PVP-I) for eye washing, a pharmaceutical product prepared in our hospital, is used to disinfect the conjunctival sac in eye surgery. Since iodine is unstable, its bactericidal activity is reduced when PVP-I is diluted. Therefore, the stability of a 0.625% PVP-I solution under various preservation conditions was studied. Its stability was evaluated by pH variation, visual inspection and the residual rate of available iodine. The 0.625% PVP-I solution was stored for 5 weeks at room temperature (25°C) and at 4°C under diffused light or in a dark place. The amount of available iodine was determined by the oxidationreduction titration method according to the fourteenth revised edition of the Japanese Pharmacopoeia (JPXIV). No apparent changes were found by pH variation or visual inspection after storage for 5 weeks either at 4°C or 25°C. The residual rates of available iodine after 5 weeks of storage were 91 % at 25°C and 98% at 4°C, thus suggesting that a reduction in available iodine is smaller at 4°C than at 25°C. This finding also suggests that a reduction in available iodine is dependent on temperature.The results of this study indicate that a 0.625% PVP-I solution for eye washing remains stable for 5 weeks if stored at a temperature of less than 4°C.

The purpose of this study was to evaluate the distribution of CPT-11 and its active metabolite, SN-38, in pleural and pericardial fluid after intravenous administration.Two patients with lung cancer were treated with intravenous CPT-11 (60 mg/m2) on days 1, 8, and 15. The CPT-11 was detected in the pleural fluid 1.5 hr after the begining of intravenous infusion, and the level reached the maximum 24 hrs later. Similarly, the active metabolite SN-38 was detected in the pleural fluid 1.5 hr after the begining of intravenous infusion, and SN-38 concentration in the pleural fluid was almost as high as that in plasma 24 hrs later. These results suggest that intravenously administered CPT-11 may penetrate the thoracic cavity and may be metabolized to SN-38 there. The proportions of maximum concentrations of CPT-11 and SN-38 in the pleural fluid to the corresponding plasma levels were 20.4% and 28.5%, respectively. In addition, the AUCs of the lactone form SN-38 were much lower than those of the carboxyl form in the pleural fluid.CPT-11, SN-38 and SN-38 glucronide showed similar pharmacokinetics in the pericardium as that in plasma.

Zyvox® (linezolid), an oxazolidinone-class synthetic antibacterial agent, has been approved for the treatment of vancomycin-resistant Enterococcus faecium infections. Although there are three forms of this drug, including injection, tablets and oral suspension, presently available overseas, only injection and tablets have so far been approved in Japan. It is possible to use ground tablets as an oral suspension. However, the quality including the stability of linezolid in such a suspension has not yet been studied. In this study, we therefore, examined the stability of linezolid in a suspension of ground tablets and the characteristics of such a suspension. The solubility of linezolid was low, and approximately 85% of linezolid was suspended in a solid phase. Linezolid was stable in the suspension, and there were no differences in the pH for up to 24 hours. However, precipitation occurred rapidly after the ground tablets had been suspended. The concentration of linezolid in the upper layer of the suspension decreased to half of the initial concentration in 15 min.In conclusion, Zyvox® was found to be stable and therefore is considered suitable to be ground and used in an oral suspension. Such suspensions should be re-suspended just before use, especially when the suspension is pre-constituted.

Hospital pharmaceutical preparations (HPP) are used in patients whose complications are not well controlled by the commercially available drugs or injections. The use of HPP is effective when HPP are proposed through clinical pharmacy services. A questionnaire was developed to evaluate the use of HPP and then was sent to 49 hospital pharmacies who belong to the Hokkaido Association for Hospital Pharmaceuticals.As a result, 32 institutions replied to questionnaire, thus indicating a recovery rate of 65%. HPP, including mixtures of injectable drugs, were used at 30 out of 32 institutions. According to the questionnaires, 11 hospitals manufactured 24 HPP which were used during clinical pharmacy services. Half of these preparations were used to care for adverse symptoms, such as stomatitis, induced by the cancer chemotherapy.The use of HPP prepared by clinical pharmacy services is closely related to patient's symptoms. The practical use of HPP is not only considered to improve drug compliance and the QOL of patients, but are also thought to enhance the general capabilities of pharmacists in clinical pharmaceutical practice.

The results of cancer chemotherapy have been improved remarkably by the development of new drugs and combining drugs in treatment. However, cancer chemotherapy protocols are complicated and the adverse effects are more severe than those of other pharmacotherapies. It was therefore felt important to create a database of protocols for the preparation and dispensing of drugs used in cancer chemotherapy. Using Microsoft Access, we have created a database from 320 protocols we have collected so far from 12 clinical departments and developed operating programs for it. The database has enabled us to search for a protocol using keywords-names of drugs, diseases and clinical departments-and most of the operations can be carried out by the click of a mouse. With our database, pharmacists are able to access protocols quickly and check prescriptions of anticancer drugs even if they are unfamiliar with computers, and we consider it to be a useful tool for this purpose.
