Study Notes
Coordination Complexes
- Formed by a metal ion and ligands, bound by coordinate covalent bonds.
- Ligands donate electrons to the metal, forming a Lewis acid-base reaction.
- Example: Silver-ammonia complex, ([Ag(NH3)2]^+).
Molecular Complexes
- Held together by non-covalent interactions: hydrogen bonds, van der Waals forces, electrostatic forces.
- Examples: drug-protein binding, surfactant micelles.
Ion Exchange Resins
- Swap ions in a solution with ions attached to the resin.
- This can purify drug solutions by removing unwanted ions.
- Drugs can form ion pairs with the resin, leading to controlled release.
Molecular Complexes by Size
- Small Molecule–Small Molecule: Example: Theophylline and ethylenediamine forming aminophylline.
- Small Molecule–Large Molecule: Example: Drug-protein complexes like iodine with polyvinylpyrrolidone.
- Large Molecule–Large Molecule: Examples include protein-protein interactions.
Protein Binding
- Affinity: Strength of the drug-protein bond.
- Concentration: Amount of drug and protein present.
- pH and temperature: Impact protein shape and binding ability.
Albumin
- Most abundant plasma protein.
Consequences of Protein Binding
- Slowed Drug Action: Bound drugs have difficulty crossing cell membranes.
- Prolonged Drug Duration: Drugs remain in the bloodstream for longer.
- Limited Distribution: Only free drugs can interact with target tissues.
Drug Interactions from Protein Binding
- Competing drugs may displace each other from protein binding sites.
- Increased free drug concentration can enhance or lead to toxic effects.
- Example: Warfarin displacement can increase bleeding risk.
