Biologics are genetically engineered medications made from living organisms such as genes or proteins. They interfere with the body’s inflammatory response by inhibiting specific components of the immune system that play a role in increasing or decreasing inflammation. These drugs are given to lessen inflammation by interfering with biologic substances that cause or worsen inflammation. Traditional drugs used to treat rheumatoid arthritis tend to suppress the entire immune system whereas biological drug therapy targets the particular components of the immune system.
