Based on the information provided, it can be inferred that tigecycline generics are not yet widely available for purchase. According to Drug Patent Watch [1], the patent for the branded version of tigecycline, Tygacil, is set to expire in 2024. This suggests that as of now, there are no generic versions of tigecycline available on the market.

Furthermore, a recent article in NCBI's PMC database [2] does not mention the availability of any generic tigecycline products. The article discusses the use of tigecycline for the treatment of various infections, but it does not indicate that generic versions of the drug are available.

Additionally, a list of new generics in the pipeline published in US Pharmacist [3] does not include tigecycline, which suggests that there are no upcoming generic versions of the drug in the near future.

In summary, based on the available information, tigecycline generics are not widely available for purchase as of now. The patent for the branded version of the drug is set to expire in 2024, and there is no mention of any generic versions of tigecycline in recent publications.
