How does Dupixent work?
Dupixent is a biologic drug designed for the treatment of allergic diseases. Biologics are drugs made from living cells. These cells can come from parts of the blood, proteins, viruses, or tissue. The process of making biologics turns products made from cells into drugs that can prevent, treat, and cure disease. These are different from most traditional drugs. Traditional drugs are made from chemicals in a lab. Their ingredients are not directly derived from living cells.1
Dupixent works by blocking 2 key proteins that contribute to the inflammation that may cause moderate-to-severe asthma. This may reduce severe flare-ups and oral corticosteroid use.1
