What are PK Characteristics of Monoclonal Antibodies and Small Molecule Drugs?

Q: What are PK Characteristics of Monoclonal Antibodies and Small Molecule Drugs?

1, Traditional small molecule drugs (1)Tissue penetration: Usually very good; (2)Binding: Usually contains distributions; (3)Degradation: Metabolic degradation; (4)Renal elimination: Usually very important; (5)Free concentration: Thought to play a role in small molecule drug activity; (6)Pharmacokinetics: Typically, linear; usually independent of pharmacodynamics. 2, Monoclonal antibody (1)Tissue penetration: Usually weak; (2)Binding: Usually involves clearance; (3)Degradation: Hydrolytic degradation of proteins; (4)Renal elimination: Rare; (5)Free concentration: Thought to contribute to function and immunogenicity; (6)Pharmacokinetics: Typically, nonlinear: usually dependent on pharmacodynamics and half-life of antigen x antibody (HAxA).
