Study Notes
Drug Actions
- Chemical antagonism is exemplified by antacids neutralizing gastric acid secretion.
Antibacterial Drug Actions
- Surfactants increase the permeability of bacterial plasma membrane.
Chelating Agents
- The primary function of chelating agents is to bind to metal ions, removing them from the body.
Antibacterial Mechanisms
- Aminoglycosides and tetracyclines inhibit protein synthesis in bacteria by binding to ribosomal subunits.
