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
Lefamulin is a pleuromutilin antibiotic used for the treatment of bacterial community-acquired pneumonia. A pleuromotilin is a more recently developed type of antibiotic that is derived from the fungus, Pleurotus mutilus. Lefamulin is available in intravenous and oral preparations and was granted FDA approval in August 2019. This drug is the first semi-synthetic pleuromutilin that has been designed for systemic administration. Lefamulin features a novel mechanism of action that shows benefit against resistant bacteria that cause pneumonia. The chemical structure of lefamulin contains a tricyclic mutilin core that is necessary for some of its antimicrobial activity.
