Mechanism of action

This product is a polyclonal antibody preparation derived from human plasma of donors with high titers of RSV-specific antibodies. When administered intravenously, these antibodies directly bind to RSV surface proteins, preventing viral attachment and entry into host cells, thereby reducing viral replication and disease severity. This passive immunization approach provides immediate but temporary protection, particularly in high-risk populations.
