    Study Notes

    Antimicrobial Drugs

    • Drugs used to prevent or treat infections caused by pathogenic microorganisms are referred to as antimicrobials; this category includes antibacterial, antiviral, and antifungal agents.

    Purpose of Chemotherapy

    • Chemotherapy is primarily aimed at treating cancer; however, it can also refer to the use of drugs to manage infectious diseases, emphasizing the destruction of pathogenic cells.

    Antimicrobial Substances

    • Antibiotics are naturally occurring substances produced by various species of microorganisms that suppress or inhibit the growth of other organisms, providing a defense mechanism against infections.

    Selective Toxicity

    • The concept of selective toxicity in chemotherapeutic agents means that these drugs selectively target the pathogenic microorganisms while minimizing harm to the host's cells, ensuring effective treatment with reduced side effects.

    Definition of Antibiotics

    • The term antibiotics typically refers to substances specifically designed to kill or inhibit the growth of bacteria, distinguishing them from other types of antimicrobial agents targeting viruses or fungi.
