GENERIC NAME: tigecycline
BRAND NAME: Tygacil
DRUG CLASS AND MECHANISM: Tigecycline is an injectable antibiotic used for the treatment of infections caused by susceptible bacteria. Tigecycline is similar to tetracycline antibiotics and has activity against a large number of bacteria. Tigecycline binds to bacterial ribosomes which produce the cell's proteins. The binding prevents bacterial ribosomes from producing important proteins needed for bacterial growth and multiplication. Tigecycline prevents bacteria from multiplying, but it does not kill bacteria. Tigecycline was approved by the FDA in June 2005.
PRESCRIBED FOR: Tigecycline is used for the treatment of complicated skin infections caused by susceptible strains of bacteria including Escherichia coli, Enterococcus faecalis, Staphylococcus aureus, Streptococcus agalactiae, Streptococcus anginosus group, Streptococcus pyogenes and Bacteroides fragilis.
Tigecycline is used for treating complicated intra-abdominal infections caused by susceptible strains of Citrobacter freundii, Enterobacter cloacae, Escherichia coli, Klebsiella oxytoca, Klebsiella pneumoniae, Enterococcus faecalis, Staphylococcus aureus, Streptococcus anginosus group, Bacteroides fragilis, Bacteroides thetaiotaomicron, Bacteroides uniformis, Bacteroides vulgatus, Clostridium perfringens, and Peptostreptococcus micros.
Tigecycline also is used for treating community-acquired bacterial pneumonia caused by Streptococcus pneumoniae, Haemophilus influenzae, and Legionella pneumophila. To prevent resistance, tigecycline should only be used to treat infections caused or very likely to be caused by susceptible strains of bacteria.
