“…According to a systematic review by Galvao et al ( 2013 ), four cases of death in the general population on account of BPG administration have been reported between 1954 and 2012. Another report by Steigmann and Suker ( 1962 ) described three more cases, unaccounted for in the review by Galvao et al In addition, the medication is currently marketed with a black-box warning regarding intravenous administration, based on several reports of inadvertent IV administration of BPG that resulted in cardiorespiratory arrest and death (Steigmann and Suker, 1962 ; Levetan et al, 1988 ; Gerber and Apseloff, 2002 ). The most likely pathophysiologic explanation for these fatalities is that the BPG compound is a crystalline powder that may cause direct damage when injected into a blood vessel, possibly eliciting vascular spasm and subsequent occlusion by the large crystals of the penicillin salt (Gerber and Apseloff, 2002 ).…”
