FLAC vs OTICAIR
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
FLAC (Fluorouracil) is a pyrimidine analog that inhibits thymidylate synthase, blocking DNA synthesis. It is converted to active metabolites (FdUMP, FUTP) that disrupt RNA function and DNA replication.
Ciprofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, disrupting DNA replication; fluocinolone acetonide is a corticosteroid that induces phospholipase A2 inhibitory proteins, reducing prostaglandin and leukotriene synthesis, thereby suppressing inflammation.
Adults: 40 mg orally twice daily.
1-2 sprays into each affected ear twice daily for 7 days. Topical route.
