Accepted November 9, 2012 A reliable, selective and sensitive LC-MS/MS assay has been proposed for the determination of nitrofurantoin in human plasma. The analyte and nitrofurazone were extracted from 100 μL of human plasma via SPE on Strata-X 33 μm extraction cartridges. Chromatography was done on a BDS Hypersil C18 (100 mm × 4.6 mm, 5 μm) column under isocratic conditions. Quantitation was d...

OBJECTIVE To investigate the role of skin biopsy in nitrofurantoin peripheral neuropathy. DESIGN We describe the clinical features and skin biopsies of 2 cases of non-length-dependent small-fiber neuropathy/ganglionopathy attributable to nitrofurantoin. SETTING Clinical evaluation and skin biopsies were performed at a tertiary teaching hospital in Baltimore, Maryland. PATIENTS A 59-year-o...

Urinary tract infection (UTI) is a common and painful human illness that, unfortunately not responsive to commonly used antibiotics in current practice. The role of fosfomycin and nitrofurantoin in the era of growing bacteria resistance has been widely discussed. In this study, we aimed to know the local antimicrobial susceptibilities, fosfomycin and nitrofurantoin susceptibility in particular,...

Solubility and permeability of nitrofurantoin (NITRO) were compared with those its cocrystals containing isoniazid (ISO), bipyridyl (BIP), or phenanthroline (PHE) as coformers, their parent mixtures. NITRO dissolution profiles evaluated via HPLC; we resorted to molecular dynamics (MD) simulations rationalize the experimental data on basis nitrofurantoin–coformers nitrofurantoin–water intermolec...

PURPOSE The activities of breast cancer resistance protein (Bcrp/ABCG2) as well as P-glycoprotein (P-gp) and drug-metabolizing enzymes can be inhibited by several flavonoids or drugs in rats. However, the species, gender and regional differences of effects of flavonoids on Bcrp/ABCG2 in rats and mice remain unclear, although Bcrp, like P-gp, is also important in controlling drug absorption and ...

OBJECTIVES To determine the in vitro resistance of group B streptococcus (GBS) to 12 antibiotics. To determine if there has been any decrease in sensitivity to the penicillins or other antibiotics currently used for GBS chemoprophylaxis in pregnant women. Find suitable alternative antibiotics to penicillin. Find an antibiotic that will have minimal selective pressure for resistance among the en...

Nitrofurantoin is a commonly used urinary tract antibiotic that has been found at high concentrations in human milk. In vivo studies in rats were carried out to determine the mechanism by which this drug crosses the mammary epithelium. Lactating rats were gavage-fed with nitrofurantoin, and their milk and plasma levels of the antibiotic were measured at intervals up to 8 hr. The average milk-to...
