What kind of drug is a monoclonal antibody?

Generally speaking, monoclonal antibody drugs, also known as monoclonal antibodies, are a type of targeted therapy and belong to the category of large-molecule biologic targeted drugs. It is recommended to use them under a doctor's guidance. Detailed analysis is as follows:

Monoclonal antibody drugs can specifically bind to a particular antigen, thereby exerting therapeutic effects. When a certain antigen is expressed in the body, monoclonal antibody drugs, as targeted therapies, act specifically on the antigen expression, forming antigen-antibody complexes that inactivate the antigen and achieve therapeutic effects. Monoclonal antibody drugs have wide clinical applications, such as in rheumatoid arthritis, breast cancer, gastric cancer, and are also used to treat certain viral or fungal infections by specifically binding to pathogen-associated antigens, thereby inhibiting the growth and replication of pathogens. Commonly used monoclonal antibody drugs include rituximab, trastuzumab, pembrolizumab, among others.

Although monoclonal antibody drugs have broad applications and promising development prospects, they may also cause some adverse reactions, such as decreased appetite, fever, nausea, vomiting, and abnormal glucose metabolism. Therefore, when using monoclonal antibody drugs, it is important to follow medical instructions and closely monitor bodily reactions, promptly reporting them to the doctor.
