ORAL
PRESCRIPTION DRUG
Nitrofurantoin capsules (macrocrystals) are 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 capsules (macrocrystals) and other antibacterial drugs, nitrofurantoin capsules (macrocrystals) 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. Nitrofurantoi

Abbreviated New Drug Application
NITROFURANTOIN- NITROFURANTOIN CAPSULE NUCARE PHARMACEUTICALS,INC. ---------- NITROFURANTOIN NITROFURANTOIN CAPSULES USP (MACROCRYSTALS) To reduce the development of drug-resistant bacteria and maintain the effectiveness of nitrofurantoin (macrocrystals) and other antibacterial drugs, nitrofurantoin (macrocrystals) should be used only to treat or prevent infections that are proven or strongly suspected to be caused by bacteria. DESCRIPTION: Nitrofurantoin, USP (macrocrystals) is a synthetic chemical of controlled crystal size. It is a stable, yellow, crystalline compound. Nitrofurantoin, USP (macrocrystals) is an antibacterial agent for specific urinary tract infections. It is available in 25 mg, 50 mg, and 100 mg capsules for oral administration. INACTIVE INGREDIENTS: Each capsule contains D&C Yellow # 10, FD&C Blue # 1, FD&C Blue # 2, FD&C Red # 40, gelatin, iron oxide black, lactose anhydrous, magnesium stearate, pregelatinized corn starch, sodium lauryl sulfate, talc and titanium dioxide. The 50 mg and 100 mg capsules also contain FD&C Yellow No. 6. CLINICAL PHARMACOLOGY: Nitrofurantoin (macrocrystals) is a larger crystal form of nitrofurantoin. The absorption of nitrofurantoin (macrocrystals) 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 four times a day 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), 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 r 전체 문서 읽기
