Abstract「要旨」健常ボランティアを対象とし, 新しい心筋血流イメージング剤99mTc-PPN1011の安全性および体内動態について検討した. 自他覚症状, 身体所見および臨床検査値には, いずれも本剤に起因すると思われる異常な所見は認められず, その安全性には特に問題はないと考えられた. 本剤静注後, 血中からのクリアランスは速やかで, 心筋への摂取は5分後で投与量の平均1.8%と高い値を示し, 3時間後でも1.0%が保持されていた. 肝臓および肺への取り込みもみられたが, 心筋に比べて急速に消失した. 静注後4時間までに投与量の4.7〜24.0%が尿中に排泄され, また, 肝・胆道系からの排泄もみられた. SPECTおよびプラナーともバックグラウンドの少ない明瞭な心筋像が得られ, 心筋イメージング剤としての安全性と有効性が示唆された.

Abstract[Summary]A new myocardial imaging agent, 99mTc-1,2-bis[bis(2-ethoxyethyl)phosphino]ethane (99mTc-PPN1011) was administered to healthy male volunteers to evaluate its safety and kinetics. No significant drug-related events were observed. After intravenous injection, blood clearance was rapid. Prompt heart uptake (1.8% of the injected dose after 5 minutes) was followed by relatively slow wash-out (1.0% remained after 3 hours). Liver and lung uptake was observed but the clearance was more rapid than in the heart. 4.7-24.0% of the injected 99mTc-PPN1011 was excreted into urine until 4 hours after injection. 99mTc-PPN1011 also seemed to be excreted through hepato-biliary system. Excellent and low-background myocardial images were obtained using either SPECT or planar imaging. We conclude that 99mTc-PPN1011 could be useful for myocardial perfusion imaging.
