Which medication is commonly prescribed to treat urinary tract infections?

Both Nitrofurantoin and Trimethoprim-sulfamethoxazole are antibiotics that are widely used to treat urinary tract infections (UTIs). Nitrofurantoin is particularly effective for uncomplicated UTIs caused by certain bacteria, as it specifically targets the urinary tract and has a targeted mechanism of action. It disrupts bacterial cell wall synthesis and protein synthesis, making it effective for treating infections in that area.

Trimethoprim-sulfamethoxazole is a combination antibiotic that works synergistically to inhibit bacterial folate synthesis, which is critical for bacterial growth and reproduction. This combination is also highly effective against a range of bacteria commonly responsible for UTIs.

Using both medications together can provide broader coverage and is often a treatment option when a patient may benefit from the properties of both drugs, especially in the case of recurrent infections or infections with resistant organisms. Thus, the correct choice is the one that recognizes the effectiveness of both Nitrofurantoin and Trimethoprim-sulfamethoxazole in treating UTIs.
