Study Notes
Antimicrobial Drugs
- Antimicrobial drugs are effective in treating infections due to their selective toxicity.
- This means they can harm or kill microbes without harming the host's cells.
Selection of Antimicrobial Agents
- Choosing the right drug depends on several factors:
- Knowing the specific microorganism causing the infection.
- Understanding the microorganism's sensitivity (susceptibility) to different drugs.
- Identifying the location of the infection in the body.
- Considering the patient's individual characteristics (patient factors).
- Assessing the drug's safety profile.
- Evaluating the cost of the treatment.
