Cortisporin
Cortisporin is a drug consisting of Neomycin, bacitracin, polymyxin B and hydrocortisone. It is a combination antibiotic and cortisone-like medicine. It can be used to treat infections of the ear canal and to help provide relief from redness, irritation, and discomfort of certain ear problems, including so-called swimmer's ear. In 2016, the drug came under scrutiny when Los Angeles Times columnist David Lazarus highlighted it as an example of unwarranted drug price markups by pharmaceutical companies. The drug is owned by Dublin, Ireland-based Endo International.
