Study Notes

Antimicrobial Drugs

Antimicrobial drugs are used to treat infections.
They work by harming invading microorganisms without harming the host cells. This is called selective toxicity.

Selection of Antimicrobial Agents

Choosing the right drug depends on several factors:
- Identifying the microorganism causing the infection.
- Determining the microorganism's sensitivity (susceptibility) to different drugs.
- Knowing the location of the infection (e.g., bloodstream, lungs).
- Considering patient factors like allergies or other health conditions.
- Assessing the drug's safety profile for the patient.
- Evaluating the cost of the treatment.
