What is Trimpex?
Trimethoprim (INN) is a bacteriostatic antibiotic used mainly in the prevention and treatment of urinary tract infections.
It belongs to the class of chemotherapeutic agents known as dihydrofolate reductase inhibitors. Trimethoprim was formerly marketed by GlaxoSmithKline under trade names including Proloprim, Monotrim, and Triprim, but these trade names have been licensed to various generic pharmaceutical manufacturers.
Trimethoprim is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.
Trimethoprim and sulfamethoxazole are commonly used in combination.
The abbreviations TRI and TMP (in clinical use) or W (in laboratory use) are common for referring to trimethoprim, but abbreviating drug names is not best practice in medicine.
