SUMMARY--What diuretic do you usually write for during CHF hospitalizations??   If you said furosemide you are not alone  One in a study in JACC 2013 looked at HF hospitalizations in 2009 and 2010 – In total 251,472 patients got a loop diuretic during their hospitalization and almost 87% got just furosemide, about 3% only got bumex, while only 0.4 received only torsemide.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4038646/#R11  What is the difference between bumetanide and furosemide? Nothing—or at least nothing we care about. No hard outcomes, no patient oriented outcomes.  Bumetanide is stronger—An article from 2015 in American Heart Journal states bumetanide is about 40 times stronger than furosemide- thus at times you might have your sphincter tighten when you go to write for 120-160mg of furosemide but feel comfortable writing for 3-4mg of bumex. They also discuss how bumetanide also appears to have a higher more consistent bioavailability at around 80-100% while furosemide seems to range from 10-100% d
