This drug contained two active principles: the anti-inflammatory molecule triamcinolone acetonide which is a synthetic glucocorticoid extensively used for over 50 years, and the broad-spectrum aminoglycoside antibiotic neomycin also used for a long time in medicine. The drug combination was recommended for the treatment of various dermatological affections such as dermatosis, eczema, local psoriasis, burns, insect bites, ocular inflammation, and other types of skin damages. Cidermex® was an ointment made with a non-fat excipient, well adapted for skin application. Neomycin is an aminoglycoside with a broad-spectrum antibacterial profile. Triamcinolone acetonide is a synthetic corticosteroid which remains extensively used today in therapeutics. This drug combination is not largely used today, although there are mentions of the use of Cidermex® in ocular therapeutics, occasionally. Triamcinolone acetonide remains extensively used to treat many types of inflammatory diseases and conditions, such as allergic rhinitis for example and in several ointments for skin applications.
