What antibiotic is used for urinary specimens only?

Nitrofurantoin is best for infections confined to the urinary tract because it is concentrated in the urine after excretion, achieving high drug levels in the bladder where most UTIs occur, while its levels in blood and tissues are low. This makes it effective for uncomplicated lower UTIs but not suitable for kidney infections or systemic infections, since it won’t reach therapeutic levels there. The other antibiotics have good systemic distribution and can treat infections beyond the bladder, so they aren’t described as urinary-tract–specific.
