  Generic Medication guide:

What is the medication available as Bactrim?

Bactrim is a development of the Swiss pharmaceutical company Roche Holding that is also available under other names but only if made by different pharmaceutical companies. The active agents of both the branded medicine and the generics are Sulfamethoxazole and Trimethoprim which make these formulations combined antibacterials.
The formulation is a chemotherapeutic substance with an ample spectrum of bactericidal action due to the blocking of folate biosynthesis in bacterial cells: Sulfamethoxazole breaks down the synthesis of dihydrofolic acid, and Trimethoprim prevents the transformation of dihydrofolic acid to tetrahydrofolic acid.
The formulation is effective against almost all groups of bacterial pathogens, i.e. gram-negative, gram-positive, and even Chlamydia, actinomycetes, and Klebsiella.
To save on the treatment, especially if you need to buy Bactrim and use it for a long period of time, you can get a generic version of the medication instead from this webpage.
