A biologic drug (biologics) is a product that is produced from living organisms or contain components of living organisms.
Biologic drugs include a wide variety of products derived from human, animal, or microorganisms by using biotechnology.
Types of biologic drugs include vaccines, blood, blood components, cells, allergens, genes, tissues, and recombinant proteins.
Biologic products may contain proteins that control the action of other proteins and cellular processes, genes that control production of vital proteins, modified human hormones, or cells that produce substances that suppress or activate components of the immune system.
Biologic drugs are sometimes referred to as biologic response modifiers because they change the manner of operation of natural biologic intracellular and cellular actions.
