What is Colistin Hydrocortisone Neomycin Thonzonium

Colistin sulfate hydrocortisone acetate neomycin sulfate thonzonium bromide is a combination antibacterial and antiinflammatory otic suspension indicated for the treatment of superficial bacterial infections of the external auditory canal and infections of mastoidectomy and fenestration cavities caused by susceptible organisms.

Colistin sulfate is a polypeptide antibiotic, which penetrates and disrupts the bacterial cell membrane, and neomycin is an aminoglycoside antibiotic, which inhibits bacterial protein synthesis.

Hydrocortisone acetate is a corticosteroid, which controls inflammation, edema, pruritus, and other dermal reactions.

Thonzonium bromide is a surface-active agent that promotes tissue contact by dispersion and penetration of the cellular debris and exudate.

Neomycin can induce permanent sensorineural hearing loss due to cochlear damage and risk is greater with prolonged use; therefore, limit use to 10 consecutive days.
