Summary
This summary is machine-generated.Dupilumab prescribing has surged in Medicare patients since 2017, with increasing costs and a broader range of specialists prescribing the drug. This trend reflects expanded Food and Drug Administration (FDA) indications.
Area Of Science
- Immunology
- Pharmacology
- Health Economics
Background
- Dupilumab, a monoclonal antibody, targets type 2 inflammation and has gained multiple Food and Drug Administration (FDA) approvals since its initial 2017 market entry.
- Understanding the evolving landscape of dupilumab utilization within the Medicare population is crucial due to its expanding indications and associated healthcare costs.
Purpose Of The Study
- To analyze trends in dupilumab prescribing patterns, prescriber demographics, and associated Medicare costs from 2017 to 2021.
- To investigate the financial impact of increasing dupilumab utilization on patients and the Medicare program.
Main Methods
- Utilized annual Medicare Part D claims data from 2017 to 2021.
- Analyzed the number of prescribers, Medicare claims, associated costs, and the distribution of prescribing specialties over the study period.
Main Results
- The number of dupilumab prescribers increased significantly from 142 in 2017 to 6,244 in 2021.
- Medicare claims rose from 2,444 to 157,401, with costs escalating from $7.59 million to $540.5 million during the same period.
- The prescriber landscape shifted, with dermatologists decreasing from 78.9% to 38.1% of providers, indicating broader adoption across specialties.
Conclusions
- Dupilumab has become a more prevalent treatment in the Medicare population, driven by expanded FDA-approved indications.
- The widespread use of dupilumab presents a substantial financial burden to both patients and Medicare.
- The changing prescriber profile reflects the drug's versatility across various therapeutic areas.

The elimination half-life and drug clearance of drugs following nonlinear kinetics can vary with dosage. The Michaelis-Menten parameters and drug concentration influence these factors. As the dose increases, the elimination half-life tends to lengthen, resulting in a reduction in clearance and a disproportionately larger area under the curve. The total clearance can be derived from the Michaelis-Menten equation for drugs following a one-compartment model.

Prescription drugs require a prescription from a medical practitioner and can only be obtained from a pharmacy. They have many applications, including treating pain, anxiety, and hypertension.
The misuse and addiction to prescription drugs is a growing problem that can affect people of all age groups, specifically teenagers. This can happen when prescription medications are used in ways not intended by the prescriber, such as taking someone else's prescription or using medication for...
Fixed-dose regimens are a common approach to administer drugs to achieve and maintain desired levels of the drug in the body. In this dosing strategy, a specific amount of medication is given at regular intervals, often multiple times a day, to ensure a consistent drug concentration in the bloodstream.
Fixed-dose regimens can be used for various routes of administration, including intravenous (IV) injections and oral medications. For IV administration, a predetermined amount of the drug is...
A drug dosage regimen describes the specific instructions and schedule for administering a drug to a patient. It considers factors such as drug dosage, frequency, route of administration, and duration of treatment. Designing an appropriate dosage regimen for a patient aims to achieve a target drug concentration at the site of action.
Typically, the starting dose and dosing interval are guided by the manufacturer's recommendations based on clinical trials conducted during and after drug...
A rational dosage regimen considers a drug's pharmacokinetics, including its absorption, distribution, metabolism, and elimination from the body. By understanding these factors, the appropriate dosage can be determined, and the dosing schedule can be designed to achieve and maintain the desired therapeutic effect while minimizing adverse effects.
In most cases, drugs are administered repetitively or infused continuously to maintain a steady-state concentration in the body. At a steady...
Post-marketing surveillance is a critical component of pharmaceutical regulation, often uncovering unanticipated adverse drug reactions (ADRs) once a drug is widely used over an extended period.
This process, termed pharmacovigilance, aims to detect, evaluate, and minimize harmful effects related to medication use. The data collection for pharmacovigilance depends on spontaneous reporting systems, where healthcare professionals or patients voluntarily report suspected ADRs.
In some cases, there...
