Par announced the launch of Cortisporin-TC (colistin sulfate, neomycin sulfate, thonzonium bromide, hydrocortisone acetate) Otic Suspension for the treatment of otitis externa caused by susceptible organisms and for the treatment of mastoidectomy and fenestration cavities caused by susceptible organisms.

Cortisporin-TC Otic Suspension combines the antibiotics colistin sulfate and neomycin sulfate; the steroid hydrocortisone acetate, and the surfactant thonzonium bromide. Colistin sulfate is a polypeptide antibiotic which penetrates into and disrupts the bacterial cell membrane. Neomycin sulfate is an aminoglycoside antibiotic which inhibits protein synthesis, disrupting the normal cycle of ribosomal function. Hydrocortisone acetate is a corticosteroid thought to act by regulating the rate of protein synthesis; it controls inflammation, edema, pruritus and other dermal reactions. Thonzonium bromide promotes tissue contact by dispersion and penetration of the cellular exudate.
