Pirifur consists of Nalidixic Acid, Phenazopyridine Hydrochloride.
Nalidixic Acid - A synthetic 1,8-naphthyridine antimicrobial agent with a limited bacteriocidal spectrum. It is an inhibitor of the A subunit of bacterial DNA gyrase.
Indication: For the treatment of urinary tract infections caused by susceptible gram-negative microorganisms, including the majority of E. Coli, Enterobacter species, Klebsiella species, and Proteus species.
Pirifur (Nalidixic Acid) is a quinolone antibacterial agent for oral administration. Pirifur (Nalidixic Acid) has marked antibacterial activity against gram-negative bacteria including Enterobacter species, Escherichia coli, Morganella Morganii; Proteus Mirabilis, Proteus vulgaris, and Providencia rettgeri. Pseudomonas species are generally resistant to the drug. Pirifur (Nalidixic Acid) is bactericidal and is effective over the entire urinary pH range. Conventional chromosomal resistance to Pirifur (Nalidixic Acid) taken in full dosage has been reported to emerge in approximately 2 to 14 percent of patients during treatment; however, bacterial resistance to Pirifur (Nalidixic Acid) has not been shown to be transferable via R factor.
Phenazopyridine Hydrochloride - A local anesthetic that has been used in urinary tract disorders. Its use is limited by problems with toxicity (primarily blood disorders) and potential carcinogenicity.
Indication: For the symptomatic relief of pain, burning, urgency, frequency, and other discomforts arising from irritation of the lower urinary tract mucosa caused by infection, trauma, surgery, endoscopic procedures, or the passage of sounds or catheters.
