Used to treat a variety of bacterial infections, including complicated skin and soft tissue infections, complicated intra-abdominal infections, and community-acquired bacterial pneumonia. It is typically reserved for cases where other antibiotics are not effective or cannot be used, due to its broad spectrum of activity against both gram-positive and gram-negative bacteria, including multi-drug resistant strains. Tigecycline is particularly valuable in hospital settings for treating infections caused by resistant organisms such as MRSA and certain Enterobacteriaceae. However, due to concerns about higher mortality risk in some patient groups and limited penetration into certain tissues, its use is generally limited to situations where alternative treatments are not suitable.
