Description and Uses
Viomycin was found independently in 1951, in the culture broth of Streptomyces puniceus by Pfizer Research Laboratories and in that of S. floridae by Parke Davis Co. It shows strong activity against Mycobacterium species and moderate activity against gram-positive and gram-negative bacteria. Viomycin has been used by intramuscular administration to treat tuberculosis, but because of its ototoxicity and renal toxicity it is being replaced by more active and less toxic drugs, such as enviomycin and other antituberculotic antibiotics.
Viomycin is a basic peptide antibiotic, which is an effective agent against multidrug-resistant tuberculosis.
