Tigecycline: A Broad-Spectrum Antibiotic for Bacterial Infections
Tigecycline is a broad-spectrum antibiotic that has been used to treat a wide range of bacterial infections. Developed by Wyeth Pharmaceuticals (now part of Pfizer), tigecycline was approved by the US FDA in 2005 for the treatment of complicated skin and skin structure infections (cSSSI) and community-acquired bacterial pneumonia (CABP). In this article, we will explore the bacterial infections that tigecycline effectively targets.
What is Tigecycline?
Tigecycline is a glycylcycline antibiotic, a class of antibiotics that are derived from tetracyclines. It works by inhibiting protein synthesis in bacteria, thereby preventing the growth and spread of infections. Tigecycline is administered intravenously and has a broad spectrum of activity against both Gram-positive and Gram-negative bacteria.
Bacterial Infections Targeted by Tigecycline
Tigecycline has been shown to be effective against a wide range of bacterial infections, including:
Complicated Skin and Skin Structure Infections (cSSSI)
Tigecycline is indicated for the treatment of cSSSI, including infections caused by methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecium (VRE), and other resistant bacteria.

Community-Acquired Bacterial Pneumonia (CABP)
Tigecycline is also indicated for the treatment of CABP, including infections caused by Streptococcus pneumoniae, Haemophilus influenzae, and other bacteria.
Intra-Abdominal Infections
Tigecycline has been shown to be effective against intra-abdominal infections, including peritonitis and abscesses.
Bacteremia and Septicemia
Tigecycline has been used to treat bacteremia and septicemia, including infections caused by MRSA, VRE, and other resistant bacteria.
Skin and Soft Tissue Infections
Tigecycline has been shown to be effective against skin and soft tissue infections, including cellulitis and abscesses.
Urinary Tract Infections
Tigecycline has been used to treat urinary tract infections, including pyelonephritis and cystitis.
Respiratory Tract Infections
Tigecycline has been shown to be effective against respiratory tract infections, including bronchitis and pneumonia.
Mechanism of Action
Tigecycline works by binding to the 30S ribosomal subunit of bacteria, thereby inhibiting protein synthesis. This prevents the growth and spread of infections.
Resistance to Tigecycline
Resistance to tigecycline is a concern, particularly in hospitals where the antibiotic is used extensively. Resistance can occur through mutations in the bacterial genome or through the acquisition of resistance genes.
Conclusion
Tigecycline is a broad-spectrum antibiotic that has been shown to be effective against a wide range of bacterial infections. Its mechanism of action and broad spectrum of activity make it a valuable tool in the treatment of complicated skin and skin structure infections, community-acquired bacterial pneumonia, and other bacterial infections.
