Does Tigecycline's Prescription Rate Correlate with Its Price?

Tigecycline, a broad-spectrum antibiotic, has been a topic of interest in the medical community due to its unique mechanism of action and potential to combat antibiotic-resistant bacteria. However, its prescription rate has been declining in recent years, sparking concerns about its accessibility and affordability. In this article, we will explore the correlation between tigecycline's prescription rate and its price, examining the factors that contribute to its usage and the implications for patients and healthcare systems.

Tigecycline: A Broad-Spectrum Antibiotic

Tigecycline is a glycylcycline antibiotic, a subclass of tetracyclines, which has been approved for the treatment of complicated skin and skin structure infections (cSSSI), complicated intra-abdominal infections (cIAI), and community-acquired bacterial pneumonia (CABP). Its unique mechanism of action involves binding to the 30S ribosomal subunit, preventing protein synthesis and inhibiting bacterial growth.

Prescription Rate Decline: A Concerning Trend

According to data from the Centers for Disease Control and Prevention (CDC), the prescription rate of tigecycline has been declining steadily since 2015. This trend is concerning, as it may indicate a lack of confidence in the antibiotic's efficacy or a shift towards alternative treatments. However, it is essential to examine the factors contributing to this decline to better understand the situation.

Price as a Factor: The Role of Cost in Prescription Decisions

One potential factor influencing tigecycline's prescription rate is its price. As a relatively new antibiotic, tigecycline is still under patent protection, which can limit competition and drive up costs. According to DrugPatentWatch.com, the patent for tigecycline is set to expire in 2024, which may lead to increased competition and potentially lower prices.

Cost-Effectiveness and Value-Based Care

The high cost of tigecycline has led to concerns about its cost-effectiveness and value-based care. In a study published in the Journal of Antimicrobial Chemotherapy, researchers found that tigecycline was more expensive than other antibiotics used to treat cSSSI and cIAI. This raises questions about its value in treating these infections, particularly in resource-constrained settings.

Alternative Treatments and Resistance

The decline in tigecycline's prescription rate may also be attributed to the emergence of alternative treatments and concerns about antibiotic resistance. As bacteria develop resistance to existing antibiotics, healthcare providers may opt for alternative treatments, such as combination therapy or newer antibiotics. However, this shift may not necessarily address the root cause of antibiotic resistance, which is the overuse and misuse of antibiotics.

Patient Access and Affordability

The decline in tigecycline's prescription rate also raises concerns about patient access and affordability. As a relatively expensive antibiotic, tigecycline may be out of reach for many patients, particularly those with limited financial resources. This can lead to delays in treatment, worsening of symptoms, and increased risk of complications.

Conclusion

In conclusion, the correlation between tigecycline's prescription rate and its price is complex and multifaceted. While the high cost of tigecycline may be a contributing factor to its declining prescription rate, it is essential to consider other factors, such as the emergence of alternative treatments and concerns about antibiotic resistance. As the patent for tigecycline is set to expire in 2024, it will be crucial to monitor the impact of increased competition on prices and accessibility.
