The Expiration of Tigecycline Patent for Injection: A Review of the Current Status
Tigecycline, a broad-spectrum antibiotic, has been a crucial tool in the fight against antibiotic-resistant bacteria. Developed by Wyeth Pharmaceuticals (now part of Pfizer), tigecycline was first approved by the FDA in 2005 for the treatment of complicated skin and skin structure infections (cSSSI) and community-acquired bacterial pneumonia (CABP). The drug's unique mechanism of action, which involves binding to the 30S ribosomal subunit of bacteria, has made it an effective treatment option for a wide range of infections.
However, as with all patented medications, the tigecycline patent for injection is set to expire, which will allow generic versions of the drug to enter the market. But when exactly does the tigecycline patent for injection expire?

The patent expiration date for tigecycline is not a straightforward issue. According to the FDA, the original patent for tigecycline expired in 2015. However, Pfizer, the manufacturer of tigecycline, had filed for and received several extensions to the patent, which have delayed the expiration of the patent.
Patent Extensions: A Common Practice
Patent extensions are a common practice in the pharmaceutical industry. Companies can file for extensions to the patent term, which can be granted for various reasons, including delays in the approval process or the need for additional clinical trials. In the case of tigecycline, Pfizer has filed for and received several extensions to the patent, which have delayed the expiration of the patent.
The Current Status of the Patent
According to DrugPatentWatch.com, a leading provider of patent information for the pharmaceutical industry, the tigecycline patent for injection is currently set to expire in 2026.
