PRESCRIPTION DRUG
Nitrofurantoin macrocrystals capsules is specifically indicated for the treatment of urinary tract infections when due to susceptible strains of Escherichia coli, enterococci, Staphylococcus aureus, and certain susceptible strains of Klebsiella and Enterobacter species. Nitrofurantoin is not indicated for the treatment of pyelonephritis or perinephric abscesses.To reduce the development of drug-resistant bacteria and maintain the effectiveness of nitrofurantoin macrocrystals capsules and other antibacterial drugs, nitrofurantoin macrocrystals capsules should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy. Nitrofurantoins lack the broader tissue distribution of other therapeutic age

NITROFURANTOIN MACROCRYSTALS- NITROFURANTOIN MACROCRYSTALS CAPSULE BLUEPOINT LABORATORIES ---------- NITROFURANTOIN MACROCRYSTALS CAPSULES To reduce the development of drug-resistant bacteria and maintain the effectiveness of nitrofurantoin macrocrystals capsules and other antibacterial drugs, nitrofurantoin macrocrystals capsules should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. DESCRIPTION: Nitrofurantoin macrocrystals capsules is a synthetic chemical of controlled crystal size. It is a stable, yellow, crystalline compound. Nitrofurantoin macrocrystals capsules is an antibacterial agent for specific urinary tract infections. It is available in 25 mg, 50 mg, and 100 mg capsules for oral administration. 1-[[(5-NITRO-2-FURANYL)METHYLENE]AMINO]-2,4-IMIDAZOLIDINEDIONE INACTIVE INGREDIENTS: Each capsule contains edible black ink, gelatin, lactose, starch, talc, titanium dioxide, and may contain FD&C Yellow No. 6 and D&C Yellow No. 10. CLINICAL PHARMACOLOGY: Nitrofurantoin macrocrystals capsules is a larger crystal form of nitrofurantoin. The absorption of nitrofurantoin macrocrystals capsules is slower and its excretion somewhat less when compared to nitrofurantoin. Blood concentrations at therapeutic dosage are usually low. It is highly soluble in urine, to which it may impart a brown color. Following a dose regimen of 100 mg q.i.d. for 7 days, average urinary drug recoveries (0 to 24 hours) on day 1 and day 7 were 37.9% and 35.0%. Unlike many drugs, the presence of food or agents delaying gastric emptying can increase the bioavailability of nitrofurantoin macrocrystals capsules, presumably by allowing better dissolution in gastric juices. _MICROBIOLOGY_ Nitrofurantoin is a nitrofuran antimicrobial agent with activity against certain Gram-positive and Gram- negative bacteria. _MECHANISM OF ACTION_ The mechanism of the antimicrobial action of nitrofurantoin is unusual among antibacterials. Nitrofurantoin is reduced by bacterial flavoproteins to reactive Citiți documentul complet
