Description
Nitrofurantoin Product Overview
Nitrofurantoin (C8H6N4O5) is a yellow crystalline powder that is very slightly soluble in water. It concentrates in the urine, where it acts against the bacteria that cause most urinary tract infections, and resistance remains low.
In addition, pharmaceutical companies use macrocrystalline nitrofurantoin and the monohydrate in capsules, including modified-release combinations of both, and in oral suspensions for uncomplicated cystitis and its prevention. Crystal size affects absorption and stomach tolerance, so the form is specified carefully. It is a first-line treatment for cystitis in many guidelines.
Notably, Zyntex supplies nitrofurantoin only to licensed pharmaceutical companies. Related urinary anti-infectives in our range include Trimethoprim and Fosfomycin Sodium.
