Gepotidacin
chemical compound
Gepotidacin, sold under the brand name Blujepa, is an antibiotic medication used for the treatment of urinary tract infection or uncomplicated urogenital gonorrhea. Gepotidacin is a triazaacenaphthylene bacterial type II topoisomerase inhibitor. It is used as the salt gepotidacin mesylate, and is taken by mouth.
Gepotidacin was approved for medical use in the United States in March 2025. The US Food and Drug Administration considers it to be a first-in-class medication. It is the first triazaacenaphthylene antibiotic to be approved in the US.
Medical uses
Gepotidacin is indicated for the treatment of females aged twelve years of age and older weighing at least 40 kilograms (88 lb) with uncomplicated urinary tract infections (uUTI) caused by Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii complex, Staphylococcus saprophyticus, and Enterococcus faecalis.
In December 2025, the indication for gepotidacin was expanded to include the treatment of uncomplicated urogenital gonorrhea in people who weigh at least 99 pounds (45 kg).
Pharmacology
Mechanism of action
Gepotidacin's primary mechanism of action involves inhibiting bacterial DNA replication, specifically targeting DNA gyrase (topoisomerase II) and topoisomerase IV. These enzymes are vital for bacterial processes such as replication, transcription, and cell division, as they regulate the topological state of DNA during these activities. Gepotidacin binds to the GyrA subunit of DNA gyrase and the ParC subunit of topoisomerase IV. Research has shown that this interaction occurs within a pocket formed by these subunits, located between the scissile DNA bonds. By binding in this region, gepotidacin inhibits the activity of these enzymes, thereby impairing bacterial replication.
The public source identifies “Gepotidacin” as chemical compound. This brief keeps that definition visible, then builds a research path around Gepotidacin, chemical and compound.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Gepotidacin”, the useful work is to connect “chemical compound” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Jul 19, 2026. The linked authority identifier is Q19597285. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2025.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
