Study Notes
Anti-Infective Agents Overview
- Anti-infective agents targeting infections caused by worms are called antihelminthics.
- Selective toxicity refers to the ability of a drug to target pathogens without harming the host. Anti-infective agents usually lack high levels of selective toxicity, affecting both pathogens and host cells.
Actions of Anti-Infective Agents
- Therapeutic actions of anti-infective agents include:
- Inhibition of pathogen growth
- Killing of pathogens directly
- Preventing pathogen replication
- Some actions that are NOT therapeutic include promoting infection or enhancing pathogen resistance.
Specific Types of Anti-Infective Agents
- Anti-infective agents specifically used for fungal infections are known as antifungals.
- Common antifungals target fungal cell walls or membranes, disrupting their integrity and function.
Functionality of Anti-Infective Agents
- Designed to target various microbes including viruses, bacteria, fungi, and parasites.
- Aim to eliminate the pathogen causing the infection while minimizing damage to the host's cells.
