Based on the information available, the potency of generic tigecycline is expected to be the same as its brand-name counterpart. Tigecycline is an antibiotic used to treat various bacterial infections, and its active ingredient is not dependent on the brand name [1].

The U.S. Food and Drug Administration (FDA) regulates the manufacturing and distribution of both brand-name and generic drugs [2]. When a generic drug, like generic tigecycline, is approved by the FDA, it means that the generic version has the same active ingredients, strength, dosage form, and route of administration as the brand-name drug [3]. Additionally, the generic drug must have the same therapeutic effects as the brand-name drug [3].

According to DrugPatentWatch.com, tigecycline's patent expired in 2018 [4], allowing other manufacturers to produce and sell generic versions of the drug. With FDA approval, these generic versions of tigecycline should have the same potency as the brand-name version.

In summary, generic tigecycline is expected to have the same potency as its brand-name counterpart, as both contain the same active ingredient and are subject to FDA regulations.
