CORTISPORIN Ointment (neomycin and polymyxin B sulfates, bacitracin zinc, and hydrocortisone ointment, USP) is a topical antibacterial ointment. Each gram contains: neomycin sulfate equivalent to 3.5 mg neomycin base, polymyxin B sulfate equivalent to 5,000 polymyxin B units, bacitracin zinc equivalent to 400 bacitracin units, hydrocortisone 10 mg (1%), and white petrolatum, qs.
Neomycin sulfate is the sulfate salt of neomycin B and C, which are produced by the growth of Streptomyces fradiae Waksman (Fam. Streptomycetaceae). It has a potency equivalent of not less than 600 µg of neomycin standard per mg, calculated on an anhydrous basis.
CORTISPORIN (NEOMYCIN/POLYMYXIN B/BACITRACIN/HYDROCORTISONE) is indicated for the following:
For the treatment of corticosteroid-responsive dermatoses with secondary infection. It has not been demonstrated that this steroid-antibiotic combination provides greater benefit than the steroid component alone after 7 days of treatment. (See WARNINGS.)
Published Studies Related to Cortisporin (Neomycin / Polymyxin B / Hydrocortisone)
Efficacy and safety of topical ciprofloxacin/dexamethasone versus neomycin/polymyxin B/hydrocortisone for otitis externa. [2004.08]
OBJECTIVES: To compare the efficacy and safety of ciprofloxacin 0.3%/dexamethasone 0.1% (CIP/DEX) otic suspension with that of neomycin 0.35%/polymyxin B 10,000 IU/mL/hydrocortisone 1.0% (N/P/H) otic suspension in patients with acute otitis externa (AOE)... CONCLUSIONS: 7 days treatment with CIP/DEX otic suspension administered twice daily is clinically and microbiologically superior to N/P/H otic suspension administered 3 times daily in the treatment of mild to severe AOE, and is equally well tolerated.
Declining susceptibility to neomycin and polymyxin B of pathogens recovered in otitis externa clinical trials. [2004.05]
BACKGROUND: Otitis externa is usually treated empirically with topical neomycin/polymyxin B/hydrocortisone. The predominant pathogens associated with this infection are Pseudomonas aeruginosa and Staphylococcus aureus... CONCLUSIONS: Although the bacterial eradication rates for both treatments in each study were equivalent, the clinical cure rate for neomycin/polymyxin B/hydrocortisone was lower (87%) than for ofloxacin (93%). Therefore, the organisms most often causing otitis externa appear to be developing resistance to neomycin and polymyxin B but not to ofloxacin.
A comparison of cortisporin and ciprofloxacin otic drops as prophylaxis against post-tympanostomy otorrhea. [2001.11.01]
Myringotomy and tube insertion, a common pediatric surgical procedure, is frequently complicated by purulent otorrhea.Therefore we recommend topical quinolone prophylaxis, which should eliminate concerns about ototoxicity, without sacrificing efficacy.
Controlled multicenter study on chronic suppurative otitis media treated with topical applications of ciprofloxacin 0.2% solution in single-dose containers or combination of polymyxin B, neomycin, and hydrocortisone suspension. [2000.11]
Otic drops of either ciprofloxacin 0.2% solution (CIP) or a combination of polymyxin B, neomycin, and hydrocortisone suspension (PNH) were administered for 6 to 12 days to patients (14-71 years old) with chronic suppurative otitis media in a randomized, nonblinded, multicenter clinical trial... This clinical trial shows that topical 0.2% ciprofloxacin solution in single-dose containers is effective and well tolerated in patients with chronic suppurative otitis media.
A double-blind comparative study of ofloxacin otic drops versus neomycin-polymyxin B-hydrocortisone otic drops in the medical treatment of chronic suppurative otitis media. [1996.04]
Active chronic suppurative otitis media poses a management problem when patients are being considered for surgical treatment...
