Therapeutic indications:

Nitrofurantoin monohydrate/macrocrystals capsules are indicated only for the treatment of acute uncomplicated urinary tract infections (acute cystitis) caused by susceptible strains of Escherichia coli or Staphylococcus saprophyticus . 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 monohydrate/macrocrystals capsules and other antibacterial drugs, nitrofurantoin monohydrate/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 agents appro

CLINICAL PHARMACOLOGY
Each nitrofurantoin monohydrate/macrocrystals capsule contains two
forms of nitrofurantoin. Twenty-
five percent is macrocrystalline nitrofurantoin, which has slower
dissolution and absorption than
nitrofurantoin monohydrate. The remaining 75% is nitrofurantoin
monohydrate contained in a powder
blend which, upon exposure to gastric and intestinal fluids, forms a
gel matrix that releases
nitrofurantoin over time. Based on urinary pharmacokinetic data, the
extent and rate of urinary excretion
of nitro
