Sulfamethoxazole/trimethoprim, commonly known as sulfameth/trimethoprim 800⁄160, is a widely prescribed antibiotic used to treat various bacterial infections. The combination of sulfamethoxazole and trimethoprim works by inhibiting the growth and reproduction of bacteria, ultimately leading to their elimination from the body. In this article, we will delve into the effectiveness of sulfameth/trimethoprim 800⁄160, its dosage tips, and what patients can expect from the treatment.
Understanding Sulfamethoxazole and Trimethoprim
Sulfamethoxazole is a sulfonamide antibiotic that works by inhibiting the production of folic acid, a crucial nutrient for bacterial growth. Trimethoprim, on the other hand, is a dihydrofolate reductase inhibitor that prevents the conversion of folic acid into its active form, tetrahydrofolate. By combining these two mechanisms, sulfameth/trimethoprim 800⁄160 creates a synergistic effect, making it more effective against a wide range of bacterial infections.

- Urinary tract infections (UTIs): Sulfameth/trimethoprim 800⁄160 is commonly used to treat UTIs caused by Escherichia coli, Klebsiella pneumoniae, and other gram-negative bacteria.
- Respiratory tract infections: The antibiotic is effective against bacterial infections such as bronchitis, pneumonia, and sinusitis.
- Skin and soft tissue infections: Sulfameth/trimethoprim 800⁄160 can be used to treat infections like abscesses, cellulitis, and folliculitis.
According to various studies, sulfameth/trimethoprim 800⁄160 has a high efficacy rate, with a reported cure rate of 80-90% for UTIs and 70-80% for respiratory tract infections.
Dosage Tips
To ensure the effectiveness of sulfameth/trimethoprim 800⁄160, it is essential to follow the prescribed dosage and administration instructions. Here are some dosage tips to keep in mind:
