Based on the available information, I can infer that there is a potential difference between the cost of the brand name drug Tigecycline and its generic equivalent.

Tigecycline is a antibiotic, primarily used to treat various types of bacterial infections. It is marketed under the brand name Tygacil by Pfizer.

According to GoodRx, the average retail price for a 30-day supply of Tygacil (Tigecycline) 50 mg capsules is around $2,111.95, though prices may vary depending on location and pharmacy. However, it's important to note that this price is for the brand name version of the drug.

On the other hand, the availability of generic versions of Tigecycline can impact the cost significantly. Generic drugs are typically less expensive than their brand-name counterparts because generic manufacturers do not have the same research and development costs as the company that originally developed the drug.

However, the provided sources do not offer specific information on the cost of the generic version of Tigecycline. Therefore, it's not possible to provide a direct comparison of costs based on the available information.

For the most accurate and up-to-date pricing, it is recommended to consult with a healthcare provider or pharmacist, as prices can vary based on location, insurance coverage, and other factors.
