Classes & Pharmacology

Antibiotics: Neomycin is active against S. aureus, E. coli, H. influenzae, K. pneumoniae, Enterobacter, Neisseriae, P. aeruginosa. Neomycin can cause hearing loss and should usually not be used for more than 10 days; it can also cause sensitization. Ofloxacin is a fluoroquinolone antibiotic active against S. aureus, P. aeruginosa, P. mirabilis, S. pneumoniae, H. influenzae, M. catarrhalis. Ciprofloxacin is a fluoroquinolone antibiotic active against S. aureus, P. mirabilis, P. aeruginosa. Colistin is active against most strains of gram negative bacteria including P. aeruginosa, E. coli, K. pneumoniae, Aerobacter.


Corticosteroids: Hydrocortisone controls inflammation, edema, pruritus. It should not be used in the presence of local viral infections and it can impede wound healing.


Ceruminolytics: Carbamide peroxide mechanically softens and loosens excessive ear wax. Triethanolamine polypeptide oleate is a surfactant that breaks up cerumen.


Drying Agents: Isopropyl alcohol and anhydrous glycerin have surface-tension releasing properties which dislodge trapped water from the sides of the ear canal, allowing it to run out or evaporate.


Preservatives: Thimerosal (a mercury derivative), parabens, sulfites, oxyquinoline sulfate, or benzalkonium chloride may cause sensitization. Benzalkonium chloride also reduces surface tension.


Excipients and Vehicle: Propylene glycol, polysorbate 80 aid in product formulation. Products that contain hydrochloric acid should be used only in the presence of an intact eardrum.


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