Fidaxomicin is a novel macrolide antibiotic used in the treatment of diarrhea caused by _Clostridioides_ (formerly _Clostridium_) _difficile_ in adult and pediatric patients over the age of 6 months. Fidaxomicin is a naturally-occurring 18-member macrocycle derived from fermentation. Because fidaxomicin contains an 18-membered lactone ring in its structure, it is referred to as a macrocyclic lactone antibiotic drug. The antibacterial activity of fidaxomicin is distinct from macrolides and rifamycins, as the bactericidal activity is time-dependent, and not concentration-dependent. Fidaxomicin was the first macrocyclic lactone antibiotic with activity against _C. difficile_, and it displays a narrow spectrum of activity against gram-positive anaerobes. It mediates its potent bactericidal action on the bacteria by inhibiting the bacterial RNA synthase
Ripretinib is a kinase inhibitor used for the treatment of advanced gastrointestinal stromal tumor (GIST) that has not adequately responded to other kinase inhibitors such as [sunitinib] and [imatinib]. Ripretinib, also known as Qinlock, is manufactured by Deciphera Pharmaceuticals and was initially approved by the FDA on May 15, 2020. It is the first drug approved as a fourth-line therapy in the specific setting of prior treatment with a minimum of 3 other kinase inhibitors.
