Drug-specific mechanisms

Drug-specific mechanisms" refers to the particular **biochemical or cellular processes** by which a drug produces its therapeutic or pharmacological effects, often describing how it interacts with its molecular target such as a receptor, enzyme, transporter, or ion channel. This term does not correspond to a single identifiable protein, receptor, or biomolecule, but instead encompasses the unique set of actions or pathways utilized by different drugs to achieve their effects[1][3][5][9][10]. Examples of drug-specific mechanisms may include enzyme inhibition, receptor agonism or antagonism, transporter blockade, or direct chemical interaction with biological macromolecules—each specific to the structure and properties of the given drug.
