Elneopa NF No. 1 and No. 2 infusions are complete parenteral nutrition solutions packaged as four-chambered bags. They have been used for home parenteral nutrition, with insulin injected into the bags for patients whose blood glucose becomes elevated. In this study, the stability of insulin in No. 1 and No. 2 bags was investigated. The quantity of insulin in Elneopa NF No. 2 was significantly lower than that in Elneopa NF No. 1. When insulin was injected into the upper chamber of either product, decreases in insulin levels were not observed. In contrast, the levels of insulin injected into the lower chamber of both products significantly decreased, with a larger difference in Elneopa NF No. 2. As the amino acid content is different between No. 1 and No. 2, amino acids may be considered a potential cause for the degradation of insulin in the bags. In addition, decreases in insulin levels were observed as the solutions passed through infusion sets just after flushing began, with both Elneopa NF No. 1 and No. 2. In conclusion, the concentration of insulin injected into the Elneopa infusion bags decreases, especially in No. 2 bags, and insulin is absorbed by the infusion sets.

Elneopa NF No. 1 and No. 2 infusions are total parenteral nutrition solutions packaged in four-chambered infusion bags. They have been used as home parenteral nutrition, with various drugs injected into the infusion bags, for treating patient symptoms. In this study, we investigated the stability of six drugs, including famotidine, scopolamine butylbromide, furosemide, bromhexine hydrochloride, betamethasone sodium phosphate, and metoclopramide hydrochloride in the infusion bags under dark conditions at 4℃ for 7 days. Additionally, we developed a high-performance liquid chromatography method to determine drug concentrations in the infusions. The concentrations of injected famotidine, scopolamine butylbromide, and betamethasone sodium phosphate remained unchanged when the four chambers of Elneopa NF No. 1 and No. 2 were opened and the infusions were mixed. Their respective concentrations in the upper and lower chambers also remained unchanged. The concentration of furosemide in the upper chamber of the No. 1 infusion bag decreased after 5 days, although no change was observed in the other chambers and the mixed infusions with the four chambers opened. The concentration of bromhexine hydrochloride slightly decreased in the upper chambers (approximately 3%) after the co-infusion but decreased significantly in the other chambers and the mixed infusions with the four chambers opened. The concentration of metoclopramide hydrochloride significantly decreased in the upper chambers after the co-infusion; however, no change in concentration was observed in the other chambers and the mixed infusion with the four chambers opened. The results of this study provide useful information on home-based parenteral nutrition.

臨床の現場で活躍する薬剤師を育成するにあたり,薬物療法の実践能力を修得することは非常に重要である.福山大学では,実務実習セミナーを通し,実習期間中に様々な施設で実習をしている学生及び,教員がともに集まり,討議をすることで,学生間の情報共有を可能とし,また発表内容を「薬物療法の実践」に焦点化することで,学生の薬物療法に係る能力を醸成してきた.しかし,COVID-19パンデミック下で,対面による実務実習セミナーが困難となり,ビデオ会議システムを用いた実務実習セミナーを実施した.ビデオ会議システムを用いることの利点,デバイスの問題への対応,自宅からの参加ならではの副次的効果,さらに,今後の可能性について紹介する.
