The antibiotic landscape has undergone significant changes in recent years, with the emergence of new resistance patterns and the need for innovative treatments. Tigecycline, a broad-spectrum antibiotic, has been a crucial addition to this landscape. In this article, we will explore the global patent landscape of tigecycline injection, including any recent extensions or changes.
What is Tigecycline?
Tigecycline is a glycylcycline antibiotic that was first approved by the US FDA in 2005 for the treatment of complicated skin and skin structure infections (cSSSI) and community-acquired bacterial pneumonia (CABP). It works by inhibiting protein synthesis in bacteria, making it an effective treatment for a wide range of infections.
