How Much Cheaper Are Tigecycline Generics Than Tygacil?
Tigecycline generics, available since FDA approval of the first version in 2022, cost 80-95% less than the branded Tygacil (Pfizer). A standard 50 mg IV vial of generic tigecycline averages $20-50 per vial in the U.S., while Tygacil lists at $300-600 per vial, depending on wholesaler pricing and contracts.[1][2]
| Form/Dosage | Generic Price (per vial) | Tygacil Price (per vial) | Savings % |
|-------------|---------------------------|---------------------------|-----------|
| 50 mg IV | $20-50 | $300-600 | 85-92% |
| Full course (6 vials/day x 7-14 days) | $840-4,200 | $12,600-50,400 | 90-95% |
Prices reflect 2024 U.S. wholesaler data (e.g., McKesson, Cardinal); actual hospital costs vary with GPO negotiations and shortages.
Why Did Generic Prices Drop So Fast?
Tygacil's key patent (US 7,485,740 for the tigecycline compound) expired in 2021 after pediatric exclusivity extension, enabling multiple ANDA approvals.[3] Accord BioPharma and Fresenius Kabi launched first generics in August 2022 via 505(b)(2) pathways, flooding supply and crashing prices within months. No major Paragraph IV challenges delayed entry.
Where Can Hospitals or Pharmacies Buy Generics Now?
Generics distribute through major wholesalers like AmerisourceBergen and McKesson at $25-45/vial in bulk. Online platforms like DrugPatentWatch list current ANDA holders and pricing trends.[3] Check FDA Orange Book for approved generics (e.g., NDC 16714-8958 for Fresenius).
What About Shortages or Price Spikes?
Tigecycline faced intermittent shortages in 2023-2024 due to manufacturing issues, pushing generic prices up 20-30% temporarily to $60/vial.[4] Branded Tygacil remains stable but pricier during peaks. Monitor ASHP or FDA shortage lists.
How Does This Compare to Other Antibiotic Generics?
Tigecycline generics follow patterns like meropenem (90% drop post-patent) but lag behind older drugs like vancomycin ($5-10/vial generic vs. $50+ branded). Glycylcycline class uniqueness limits competition, keeping generics above $20/vial vs. pennies for penicillins.[1]
