Main information about Bactrim

Bactrim contains two active ingredients which have antibacterial characteristics. This drug has Trimethoprim and sulfamethoxazole.

The active ingredients of Bactrim break sequential processes in the bactericidal cell:

  • Sulfamethoxazole breaks synthesis of dihydrofolic acid inside the cells of the pathogenic microflora
  • Trimethoprim breaks the next chain and prevents a recovery of dihydrofolic acid

As a result of this process, morbific microorganisms do not receive ingredients needed for the development, and therefore they lose their functions and gradually die.

Bactrim antibiotic provides a bactericidal action to bacteria with gram-positive and gram-negative structure of the cellular wall.

The maximal concentration of Bactrim in the blood plasma is observed in 2-3 hours after a one-time use of the therapeutic dose. This is a fast value due to which a therapeutic effect happens faster than using other antibacterial drugs.

The highest concentrations of Bactrim are observed in the organs of the respiratory and urinary systems, and therefore this drug is more effective in the treatment of cystitis, urethritis, gonococcal urethritis, prostatitis, pyelonephritis, chronic bronchitis, pneumonia and other bacterial diseases of these systems.
