General Information

Macrobid is an antibiotic. It fights bacteria in the body. Nitrofurantoin is an antibacterial agent definite for urinary tract infections. Nitrofurantoin chemical name of nitrofurantoin macrocrystals is 1-[5-nitro-2-furanyl]methylene]amino]- 2,4-imidazolidinedione. Nitrofurantoin is not indicated for the treatment of pyelonephritis or perinephric abscesses. Nitrofurantoin is lessened by bacterial flavoproteins to reactive intermediates that inactivate or variate bacterial ribosomal proteins and other macromolecules.

As a consequence of such inactivations, the vital biochemical processes of protein synthesis, aerobic energy metabolism, DNA synthesis, RNA synthesis, and cell wall synthesis are inhibited. Nitrofurantoin, in the form of Macrobid, has been shown to be active against most stretches of the following bacteria both in vitro and in clinical infections. Twenty-five percent is macrocrystalline nitrofurantoin, that has slower dissolution and absorption than nitrofurantoin monohydrate. The unexpended 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.
