Key points
- An antibiotic that blocks the folate metabolism bacteria need to build DNA and proteins, stopping them from growing and dividing.

- Mild skin rash or digestive discomfort can occur, while persistent fever or signs of allergic reaction need immediate medical assessment.
What is Trimethoprim?
Trimethoprim is a targeted medication that functions as one of the essential Antibiotics. It works by inhibiting the specific enzymes that bacteria need to survive and reproduce. Because different preparations are manufactured to suit various needs, clinical options may vary in how the active ingredient is delivered to the body.
What Trimethoprim is used for
This medication is widely utilised to manage symptoms and source causes of a Bacterial Infection. By disrupting the processes that allow pathogens to thrive, it stops the bacterial population from increasing, allowing the body to clear the infection naturally.
How does Trimethoprim work?
The mechanism of this medication focuses on folate metabolism. Bacteria, unlike human cells, must produce their own metabolic precursors to create DNA and proteins; this drug blocks that production. When bacteria cannot produce these essential building blocks, they stop growing and dividing. This action is effective against a broad range of bacterial strains often associated with common infections.
