What is cotrimoxazole?

Cotrimoxazole is a combination antibiotic that contains two active ingredients: sulfamethoxazole and trimethoprim. It is commonly used to treat a variety of bacterial infections, including urinary tract infections, respiratory infections, and certain types of pneumonia. The dual action of the drugs in cotrimoxazole works synergistically to inhibit bacterial folic acid synthesis, enhancing its effectiveness against susceptible bacteria. It is important to use this medication under a healthcare provider's guidance due to potential side effects and resistance issues.
