The Expiry Date of Tigecycline Injection Patent: Unraveling the Mystery

Tigecycline, a broad-spectrum antibiotic, has been a game-changer in the treatment of severe infections. However, with the patent expiration date looming, the pharmaceutical industry is bracing for the impact on the market. In this article, we'll delve into the world of patent law and explore the expiry date of tigecycline injection patent.

What is Tigecycline?

Tigecycline is a glycylcycline antibiotic, a subclass of tetracyclines. It 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). Tigecycline's unique mechanism of action makes it effective against a wide range of bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecalis (VRE).

The Patent Landscape

Tigecycline is marketed by Pfizer under the brand name Tygacil. The original patent for tigecycline injection was filed in 1999 and granted in 2002. However, patent expiration dates vary by country, and it's essential to understand the complex patent landscape.
