Overview
Triamcinolone/Nystatin/Neomycin/Gramicidin is a combination topical medication containing a corticosteroid (triamcinolone acetonide), an antifungal (nystatin), and two antibiotics (neomycin sulfate and gramicidin). It is used to treat inflammatory skin conditions complicated by bacterial and/or fungal infections.
Mechanism of Action
Triamcinolone acetonide is a synthetic corticosteroid that suppresses inflammation by inhibiting inflammatory mediators. Nystatin binds to ergosterol in fungal cell membranes, causing membrane permeability and cell death. Neomycin is an aminoglycoside antibiotic that inhibits bacterial protein synthesis. Gramicidin is a polypeptide antibiotic that disrupts bacterial cell membrane integrity.
Indications
- Inflammatory dermatoses (eczema, dermatitis) with secondary bacterial or fungal infections
- Corticosteroid-responsive dermatoses complicated by infection
Dosage
Apply a thin layer to affected area 2-4 times daily. Duration should be limited to avoid systemic absorption and adverse effects.
