Defuzin
Defuzin Uses, Dosage, Side Effects, Food Interaction and all others data.
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 is active against a wide range of gram-positive organisms. The sustained release formulation ensures prolonged contact with the conjunctival sac. Fusidic acid penetrates well into the aqueous humor.
Fusidic acid is a bacteriostatic antibiotic and helps prevent bacterial growth while the immune system clears the infection.
