Excipient Lung Disease is an inflammatory response to the intravenous administration of oral formulations of drugs and their excipients (additives). Previously described offenders include opioids and Ritalin, whose excipients, when crushed and administered intravenously, lead to inflammation and are demonstrated by centrilobular nodules and ground-glass formations on Chest Computed Tomography. In this case report, we demonstrate Chest CT findings of excipient lung disease in a patient using etizolam, a benzodiazepine derivative commonly used as an anxiolytic in Japan. Of note, the patient acquired etizolam for purchase through online retailers without prescription, which is becoming more common occurrence and offers the additional risk of unknown formulations.
