At a glance
Hydrocortisone + Neomycin Sulphate + Polymixin B E/E prep is used for bacterial ear infections and ocular inflammation with suspected or confirmed bacterial infection.
Indications
- Otitis externa (outer ear infection)
- Ocular inflammation with suspected or confirmed bacterial infection
Pharmacology
Neomycin, an aminoglycoside, binds to the 30S subunits of the bacterial ribosome, inhibiting protein synthesis and thereby disrupting DNA synthesis. Polymyxin B disrupts bacterial cell membrane and has bactericidal action against most Gram-negative bacilli. Hydrocortisone, a corticosteroid with mainly glucocorticoid activity, suppresses inflammatory response.
