HOW DO ANTIBIOTIC COMBOS WORK?

Antibiotic combos consist of a combination of two or more antibiotics used for treating:

Sulfamethoxazole when given in combination with trimethoprim stops the bacteria from growing and multiplying and causes their death.

Sulfamethoxazole does not kill the bacteria but interferes with their ability to grow and multiply (bacteriostatic). Bacteria need folic acid for their growth and multiplication. A sulfa drug interrupts the bacteria’s ability to use folic acid, thus inhibiting the growth process. As a result, the bacteria fail to reproduce. As humans rely on diet for obtaining folic acid, they are usually safe against the adverse effects of inhibition of folate production.

Trimethoprim kills the bacteria by inhibiting the enzyme dihydrofolate reductase, thereby blocking the production of folic acid. Folic acid is essential for bacterial cells to survive, and the lack of this mineral can kill the bacteria.
