Erytyl-F (Oral Powder) is a broad spectrum combination of Macrolide and Nitrofuran antibiotics. It binds reversibly to the 50S ribosomal subunit causing impaired protein synthesis leading to inhibited bacterial growth. It is reduced by bacterial flavoproteins to reactive intermediates that inhibit bacterial ribosomes and other macromolecules leading to inhibition of protein, DNA, RNA & cell wall synthesis and aerobic energy metabolism. Indications: Erytyl-F (Oral Powder) has an expansive spectrum which includes both Gram-positive and Gram-negative bacteria. It is indicated for the treatment of respiratory tract infections like CRD, CCRD, Infectious Coryza, Mycoplasmosis and Air sacculitis.
