    Summary

    Rifampicin significantly impacts rat metabolism, concentrating in the liver and disrupting nutrient absorption, particularly lipids and sugars. This antibiotic also shows toxicity to liver cells.

    Area of Science:

    • Pharmacology
    • Toxicology
    • Biochemistry

    Background:

    • Rifampicin (RMP) is a crucial antibiotic.
    • Understanding RMP's metabolic and tissue distribution is vital for patient safety.

    Purpose of the Study:

    • To investigate the effects of rifampicin on metabolic equilibrium in male rats.
    • To determine the tissue distribution of rifampicin.

    Main Methods:

    • A 12-day experimental study was conducted on male rats.
    • Biochemical indices of metabolic equilibrium were monitored.
    • Rifampicin concentrations in various tissues were analyzed.

    Main Results:

    • Rifampicin concentration was highest in the liver, significantly exceeding blood levels.
    • Epididymal fat showed half the rifampicin concentration of blood.
    • Rifampicin adversely affected energy metabolism, including nutrient intake and resorption, especially lipids and sugars.
    • Hepatotoxicity was observed, indicating harm to liver parenchyma.

    Conclusions:

    • Rifampicin disrupts metabolic equilibrium in rats.
    • The liver is a primary site for rifampicin accumulation.
    • Rifampicin negatively impacts nutrient metabolism and liver health.
