How does Posatex work?
In dogs, ear infections can be caused by bacteria or fungi. Infections can often cause inflammation of the ear (s) (redness, swelling or itching). Two of the active substances in Posatex, orbifloxacin and posaconazole, act against the cause of the infection, while the third, mometasone furoate monohydrate, acts on inflammation.
Orbifloxacin is an antibiotic that belongs to the group of fluoroquinolones. It works by blocking an enzyme called "DNA gyrase", which is important because it does not allow bacteria to make copies of DNA. By blocking "DNA gyrase", orbifloxacin prevents bacteria from producing DNA and proteins and growing, leading to bacterial death.
Posaconazole is an antifungal that belongs to the triazole group. It works by preventing the formation of ergosterol, which is an important part of the fungal cell wall. Without ergosterol, the fungus is destroyed or prevented from spreading.
Mometasone furoate monohydrate is a steroid that is a type of substance that helps reduce inflammation.
