What are targeted drugs?
The word "targeting" is familiar to many as an economic term derived from the English word "target" and meaning a target choice from a set (for example, the choice of a part of the audience). In medicine, the term is increasingly used to describe selective treatments.
When they talk about selectively acting therapy, they use the term "targeted therapy", when they mean the targeted action of a drug, they talk about targeted drugs.
Targeted drugs are drugs that selectively affect certain biological objects. Such drugs are considered to be smart remedies, the effect of which captures only the planned objects for treatment. The targeted drug targets and acts on markers - for example, proteins, the structure and properties of which are genetically altered, and which are considered foreign.
The action of targeted drugs is akin to the action of immune agents that selectively attack antigens, therefore, targeted therapy is equated in its action with immunotherapeutic treatment, that is, treatment with immunomodulators.
The most valuable application of targeted drugs is found in the treatment of oncological diseases, where a targeted effect on cancer cells is required without affecting other biological structures. Often, targeted drugs are called biopreparations, and targeted therapy is called biotherapy, due to the fact that this kind of therapy in its action is capable of sensibly isolating only those biological objects to which it is directed.
Targeted therapy competes with chemotherapy and radiation therapy today, as it is more sparing in relation to healthy tissues of the body. Research in targeted therapy is ongoing and includes the search and biological evaluation of target molecules for the development of new, more accurate targeted drugs.
