cefpodoxime proxetil

CHEBI:3505 ·resolve ·ANTIBACTERIAL ·EXACT SEEDED

The 1-[(isopropoxycarbonyl)oxy]ethyl (proxetil) ester prodrug of cefpodoxime. After swallowing, hydrolysis of the ester group occurs in the intestinal epithelium, to release active cefpodoxime in the bloodstream. It is used to treat acute otitis media, pharyngitis, and sinusitis. — ChEBI

Cross-references

Identifiers for this same structure in other resources. An accession that lands on two different structures in this corpus is withheld from both rather than shown here, since it names at most one of them.

Drug registries

Identifiers that name a drug rather than a structure. One of these can cover a parent compound, its salts and its stereoisomers, which this corpus keeps as separate records, so it is not an equivalence of structure.

Patents and articles

Documents about this compound. A patent covers a class and an article covers a topic; neither identifies a structure.
