Dacarbazine (DTIC) produces adverse reactions including local venous pain during the intravenous injection. DTIC is reported to be photolyzed to produce certain kinds of pain producing substances. 5-diazoimidazole-4-carboxamide (Diazo-IC) is considered to be a causative photolyte of venous pain. A newly designed cover shield has been used at Osaka University Hospital when DTIC is administered for the last 4 years. This shield comprises black cotton and covers both the infusion bag and route of infusion. We evaluated the effectiveness of this new shield against photodegradation of DTIC by determining the concentration of Diazo-IC. DTIC was dissolved with an injection solvent and mixed with 5% dextrose in water. Prepared samples were divided into 3 groups (without shield, infusion bag covered with shield, and infusion bag and infusion route covered with shield) and exposed under natural light conditions indoors. Prepared solutions ran down through the route and those samples were taken before and after passing the route pipe. Diazo-IC in the samples was measured by HPLC. Production of Diazo-IC in the non-covered bag was significantly increased in comparison with that in covered infusion bags. Diazo-IC production in samples after passing through the route was significantly increased compared with that in samples taken before passing through the route of the non-covered shield and covered infusion bag only. For the covered infusion bag and infusion route, the samples taken before and after passing through the route did not show significant differences. These data suggest that the new shield, which almost perfectly covers both the infusion bag and route of infusion, is effective in preventing DTIC photodegradation.

Some powder formulations of anticancer drugs are currently distributed under negative pressure in vials. However, the internal pressures of the vials are not described in the package inserts. Therefore, an awareness survey was conducted involving pharmacists regarding their descriptions.Anonymous questionnaires, consisting of a 5-grade scale and free description questions, were distributed to the member hospitals of Hyogo Pharmaceutical Society, and responses were collected by FAX and 2-top ratio analysis was performed. In addition, an intergroup comparison was conducted by dividing the responders into two groups based on their experiences (i.e., more or less than 3 years) of dispensing anticancer drugs.Responses were collected from 246 pharmacists of 67 hospitals: “Need prior information” (82.5%) and “Need description” (79.3%). Among the pharmacists with experience of less than 3 years, “Feel anxiety,” “Need prior information,” and “Feel safe with description” were more common (P < 0.05). Of them, 79.3% specified description sites: vial body (90.8%), cap (65.1%), and package insert (39.5%). Internal pressures were listed on a sheet or described in the procedure manual in only 13 hospitals, demonstrating dependence on dispensers' experiences. Besides the internal pressure, they needed information on the recommended gauge, amount of dissolution, and kind of solvent on the vial bodies.
