Fentanyl, a potent opioid agonist, was developed in the 1950s to fill a need for strong and rapid analgesia. Because of these characteristics, fentanyl is commonly used to treat chronic cancer pain or in anesthesia.[Label,L6598,L6601,L6604,L6607,L922,L6610,L6613] Fentanyl is related to other opioids like [morphine] and [oxycodone]. Fentanyl's high potency has also made it a common adulterant in illicit drugs, especially heroin. In 2017, 47600 overdose deaths in the United States involved some opioid (over 2/3 of all overdose deaths). Opioid overdoses kill an average of 11 Canadians daily. Fentanyl was FDA approved in 1968.[Label,L6598,L6601,L6604,L6607,L922,L6610,L6613]
Ketoconazole is an imidazole antifungal agent used in the prevention and treatment of a variety of fungal infections.[FDA Label] It functions by preventing the synthesis of ergosterol, the fungal equivalent of cholesterol, thereby increasing membrane fluidity and preventing growth of the fungus.[A181802,T116] Ketoconazole was first approved in an oral formulation for systemic use by the FDA in 1981. At this time it was considered a significant improvement over previous antifungals, [miconazole] and [clotrimazole], due to its broad spectrum and good absorption. However, it was discovered that ketoconazole produces frequent gastrointestinal side effects and dose-related hepatitis.[A188054,A188057] These effects combined with waning efficacy led to its eventual replacement by triazole agents, [fluconazole], [itraconazole], [voriconazole], and [posaconazole]. Ketoconazole and its predecessor [clotrimazole] continue to be used in topical formulations.
