Fusidic acid is a steroidal antibiotic with a narrow spectrum of activity, mainly effective against gram-positive bacteria. It works by inhibiting bacterial protein synthesis through interference with elongation factor G. Fusidic acid is commonly used in the treatment of skin and soft tissue infections. It is especially effective against Staphylococcus aureus, including methicillin-resistant strains (MRSA). The drug is available in topical forms such as creams and ointments, as well as oral and injectable preparations in some cases. Fusidic acid is widely used in dermatology for conditions like impetigo and infected eczema. It helps reduce bacterial growth and inflammation at the site of infection. The drug is generally well tolerated when used topically. Systemic use requires careful monitoring due to potential side effects. Overall, fusidic acid plays an important role in managing staphylococcal infections.
