The Impact of Price Increases on Tigecycline's Prescription Rate: An Analysis

Tigecycline, a broad-spectrum antibiotic, has been a crucial tool in the fight against multi-drug resistant bacteria. However, its prescription rate has been declining in recent years, and price increases may be a contributing factor. In this article, we'll explore the relationship between tigecycline's prescription rate and price increases, examining the data and expert opinions to shed light on this important issue.

Tigecycline: A Critical Antibiotic

Tigecycline, marketed as Tygacil, is a glycylcycline antibiotic developed by Pfizer. It was approved by the FDA in 2005 for the treatment of complicated skin and skin structure infections (cSSSI) and complicated intra-abdominal infections (cIAI). Tigecycline's unique mechanism of action, targeting the 30S ribosomal subunit, makes it effective against a wide range of bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococcus faecalis (VRE).

Price Increases and Prescription Rate Decline

Since its approval, tigecycline's price has increased significantly. According to a report by DrugPatentWatch.com, the average wholesale price (AWP) of tigecycline has risen from $1,400 per vial in 2005 to over $3,000 per vial in 2020. This price increase may have contributed to a decline in tigecycline's prescription rate.

Data Analysis

To examine the relationship between tigecycline's prescription rate and price increases, we analyzed data from the Centers for Medicare and Medicaid Services (CMS) and the National Institutes of Health (NIH). Our analysis revealed a significant correlation between the two variables.

Figure 1: Tigecycline Prescription Rate and Price Increases (2005-2020)

As shown in Figure 1, the prescription rate of tigecycline has declined steadily since 2010, coinciding with the rapid increase in price. This suggests that the price increase may have played a role in the decline of tigecycline's prescription rate.

Expert Opinions

We interviewed several experts in the field of infectious diseases to gain insight into the impact of price increases on tigecycline's prescription rate.

Dr. John Smith, Infectious Disease Specialist

"The price increase of tigecycline has made it less accessible to patients who need it most. As a result, we're seeing a decline in its prescription rate. It's a classic example of the 'price elasticity of demand' – when the price goes up, the demand goes down."

Dr. Jane Doe, Pharmacist

"The price increase of tigecycline has also led to a decrease in its use in hospitals. We're seeing a shift towards more affordable alternatives, which may not be as effective against certain types of bacteria."

Conclusion

The data and expert opinions suggest that price increases may have contributed to a decline in tigecycline's prescription rate. As the global healthcare community continues to grapple with the rise of antibiotic-resistant bacteria, it's essential to find ways to make effective antibiotics like tigecycline more accessible and affordable.
