The longer half-lived iodine-125 is also occasionally used when a longer half-life radioiodine is needed for diagnosis, and in brachytherapy treatment (isotope confined in small seed-like metal capsules), where the low-energy gamma radiation without a beta component, makes iodine-125 useful.
Split and merge into it. Answered by The Community. Making the world better, one answer at a time. Macrodantin is all macrocrystalline nitrofurantoin while Macrobid is a combination of the macrocrystalline nitrofurantoin as well as the nitrofurantoin monohydrate form (25% and 75% respectively).
Nitrofurantoin. Nitrofurantoin (Furadantin, Macrodantin) is an antibiotic that is used specifically for urinary tract infections as an alternative to TMP-SMX or a quinolone. Unlike many of the other drugs, however, it is usually taken for 7 - 10 days, even in cases of simple cystitis.ntil recent years, the standard treatment for a UTI was 10 days of amoxicillin, a penicillin antibiotic, but it is now ineffective against E. coli bacteria in up to 25% of cases. A combination of amoxicillin-clavulanate (Augmentin) is sometimes given for drug-resistant infections.
