How Do Patents Affect Drug Pricing?
Patents grant pharmaceutical companies exclusive rights to market their drugs for a specific period. This exclusivity allows companies to recoup research and development costs and generate profits. Once patents expire, generic or biosimilar versions of the drug can enter the market, which typically leads to a significant decrease in price.
What is Dupixent Used For?
Dupixent is a prescription medication used to treat moderate-to-severe atopic dermatitis, moderate-to-severe asthma, and other allergic conditions [2]. It works by blocking key proteins (IL-4 and IL-13) that drive inflammation in these diseases.
