Every tablet contains: Nalidixic corrosive 500 mg Phenazopyridine hydrochloride 50 mg Signs: PIRIFUR® is shown for the treatment of urinary tract diseases and attending indications delivered by gram-negative microorganisms touchy to nalidixic corrosive, including E. coli, Enterobacter sp, Klebsiella sp.. what's more, most Proteus sp. Pharmacokinetics: Nalidixic corrosive has a place with the gathering of quinolones and has a powerful bactericidal action in any urinary pH. It has been accounted for chromosomal imperviousness to traditional helpful measurements of nalidixic corrosive; notwithstanding, it has not been discovered exchanging bacterial imperviousness to antimicrobial element pathway R. PIRIFUR® has a stamped antibacterial action against gram negative microbes including Escherichia coli, Morganella morganii, Proteus mirabilis, P. vulgaris, Providencia rettgeri; Enterobacter, Klebsiella, and a few strains of Pseudomonas. The pain relieving and neighborhood analgesic activity on pollakiuria phenazopyridine urinary tract, alleviates agony, blazing, direness, criticalness and urinary diseases present. Additionally, the bactericidal operators kills contamination. After organization, PIRIFUR® is quickly consumed from the gastrointestinal tract. It is in part metabolized in the liver and quickly discharged through the kidneys. Groupings of nalidixic corrosive in pee, kidney, lung, prostate, bile, macrophages and neutrophils at higher serum levels are recognized. Nalidixic corrosive focuses in CSF and prostatic liquid are littler than those in serum. The in place nalidixic corrosive shows up in the pee together with a dynamic metabolite hidroxinalidíxico corrosive which has a comparable bactericidal movement of nalidixic corrosive. After organization of a measurement of 1 g of nalidixic corrosive, top plasma levels of dynamic medication is acquired in one to two hours, averaging around 20 to 40 ug/ml. In pee, the top medication levels midpoints from 150 to 200 ug/ml, three to four hours after organization. Urinary convergences of the dynamic mixes above 50 ug/ml (five times the base inhibitory fixation) are acquired for 8 to 12 hours. Roughly 4% of the medication is discharged in the defecation. Crystalluria has not been watched brought about by the organization of PIRIFUR.
