How does Trimethoprim work?
Trimethoprim is an antibiotic. It is used to treat infections with bacteria. Bacterial grow and multiply by producing genetic materials for the cells. The bacteria need folic acid to grow the genetic material. Unlike humans that take up folic acid from the diet, bacteria synthesize folic acid themselves. Trimethoprim works by stopping the folate production by the bacteria. With no folate produced, the bacteria will not be able to produce the genetic material necessary for their growth and multiplication. By preventing the bacteria from producing folate, trimethoprim stops the spread of infection in the human body. The remaining bacteria will eventually die or are killed by the immune system.
The doctor should make sure that the bacteria causing the infection are susceptible to trimethoprim before prescribing the medication. The doctor may take a tissue sample from the infected area and the bacteria present in the sample will be cultured and examined later for identification.
What are the benefits of taking Trimethoprim?
When administered to a patient with an infection caused by bacteria that are susceptible to trimethoprim, the bacteria will be deprived of their ability to produce folic acid, which the bacteria will synthesize to produce the genetic material necessary for growth and multiplication.
Trimethoprim stops the growth and multiplication of the bacteria, arresting the infection.
Doctors must make sure that the bacteria causing the infection are susceptible to trimethoprim, otherwise the infection will not be treated.
Trimethoprim is effective in stopping the growth and multiplication of bacteria that caused the infection.
