Indications

Fusidic Acid is indicated for the topical treatment of superficial bacterial infections of the eye and its adnexa. These may include - bacterial conjunctivitis, blepharoconjunctivitis, blepharitis, sty and keratitis. It may also be used for the management of corneal and conjunctival abrasions and foreign body injuries.

Pharmacology

Fusidic acid is an antimicrobial agent that inhibits bacterial protein synthesis. Fusidic acid interferes with amino acid transfer from aminoacyl-tRNA to protein on the ribosomes.

Fusidic acid penetrates well into the aqueous humor.
