They are nonselective and cidal

1. They lower the SURFACE TENSION of cell membranes
2. These polar molecules bind to the lipid layer and penetrate the internal hydrophobic region
3. Leave "leaky spots"

1. Nature of infecting microorganism
2. Degree of microorganisms sensitivity to drugs
3. Overall medical condition of patient

1. Drug cant diffuse into body compartment
2. Unnoticed resistant cells
3. Infection caused by more than one pathogen

1. Nature & spectrum of drug
2. Potential adverse effects
3. Condition of patient 

1. prevent penetration of virus into host
2. block replication, transcription, translation of viral material
