Pipemidic acid is primarily used as an antibacterial agent, particularly effective against Gram-negative bacteria. It is commonly prescribed for treating urinary tract infections (UTIs) caused by susceptible organisms. The chemical works by inhibiting bacterial DNA gyrase, an enzyme essential for DNA replication, thereby stopping bacterial growth. It is often administered orally in the form of tablets or capsules. Pipemidic acid is also used in some cases for gastrointestinal infections and respiratory tract infections, though its use is more limited in these areas. It is generally well-tolerated, but like all antibiotics, it should be used judiciously to avoid the development of resistant bacterial strains.
