重磅药物模型

The blockbuster model became the dominant strategy for large pharmaceutical companies in the late 20th century. The model relies on developing and patenting a drug that can treat a widespread chronic condition, such as high cholesterol (e.g., Lipitor), acid reflux (e.g., Prilosec), or depression (e.g., Prozac). Once approved, the company launches a massive marketing campaign aimed at both physicians and consumers (in countries where direct-to-consumer advertising is legal). The goal is to achieve widespread prescription and capture a large market share. The drug’s patent provides a period of market exclusivity, typically 20 years from the filing date, during which the company can charge high prices without competition from generic versions. The enormous profits generated during this period are used to recoup the substantial R&D investment—often exceeding $1 billion per approved drug—and to fund the development of the next generation of potential blockbusters. However, this model faces significant challenges. The “low-hanging fruit” of common diseases has largely been addressed, making new discoveries more difficult. Increased pressure from payers (governments and insurance companies) to control costs, and the looming “patent cliff” (when patents for multiple blockbuster drugs expire around the same time), have forced the industry to reconsider this strategy. Many companies are now shifting towards developing more specialized, high-value drugs for smaller patient populations, such as orphan drugs for rare diseases or personalized cancer therapies, which can command even higher prices per patient.
