Otomax Suspension general information
What is Otomax Suspension used for?
Otomax Suspension is a combination medication used as a topical treatment for chronic and acute otitis externa in dogs. Otitis externa is an infection of the outer ear that is caused by fungi and/or bacteria. Otomax Suspension is also effective for treating inflammation that is caused by the infection and helps relieve symptoms including itching, discomfort, redness and swelling.
How does Otomax Suspension work?
Otomax Suspension contains three medications for topical treatment of ear infection and inflammation in dogs. Gentamicin sulphate in Otomax Suspension is an aminoglycoside antibiotic and is effective against a wide range of susceptible bacteria that can cause ear infection in dogs. It works by inhibiting bacterial protein synthesis, which prevents the bacteria from producing important proteins needed to grow and kills the bacteria. Betamethasone in Otomax Suspension is a synthetic corticosteroid that works as an effective anti-inflammatory by blocking the production of inflammatory chemicals like prostaglandins and leukotrienes; also cyclooxygenase (COX 1 and COX 2), the enzymes specifically involved in prostaglandin production. Clotrimazole in Otomax Suspension is a broad spectrum antifungal used to treat fungal infections of the skin. It is effective against the yeast Malassezia pachydermatis (formerly Pityrosporum canis) that causes ear infections in dogs. It works by inhibiting the synthesis of ergosterol, an important component of fungal cell membrane that is not found in animal cells. This weakens the fungal cell membrane causing the cell contents to leak out killing the fungus. The three components of Otomax Suspension work together to fight the infection that causes otitis; they also help relieve symptoms of inflammation caused by the infection.
