    Study Notes

    Antibiotics

    • Defined as substances produced by certain microorganisms and their synthetic analogues that selectively kill or inhibit the growth of other microorganisms.
    • Distinction made between natural antibiotics and synthetic versions which mimic their effects.

    General Principles of Anti-Infective Therapy

    • Emphasizes the importance of clinical judgment related to microbiological factors in treatment decisions.
    • Requires definitive identification of the bacterial infection and analysis of the microorganism’s susceptibility to drugs.
    • Involves determining the optimal route of administration, dosage, dosing frequency, and duration for effective treatment.

    Duration of Antibacterial Treatment

    • The minimal duration typically recommended is not less than 5 days, but clinical judgment can affect this timeframe based on specific infections and patient response.

    Rational Anti-Microbial Combination

    • Used to achieve synergistic effects when a single agent is ineffective against microorganisms.
    • Aims to provide broad coverage against diverse pathogens.
    • Helps in preventing the emergence of resistance, making treatment more effective in the long term.
