In dogs with congestive heart failure, does the use of torasemide as a first line diuretic result in a superior survival time when compared to furosemide?
Clinical bottom line
Category of research question
The number and type of study designs reviewed
Five studies were critically appraised, they were all prospective randomised controlled trials
Strength of evidence
There is currently a lack of studies looking at comparing furosemide directly with torasemide in patients with congestive heart failure. There are many similarly drawn conclusions from the studies: torasemide is not inferior to furosemide in the treatment of CHF, torasemide is comparable to furosemide at one tenth the dose (or less) and that torasemide may be more effective at diuresis than furosemide with a prolonged duration of action
There is currently no clear and obvious benefit for the use of torasemide, over furosemide, as a first line diuretic for dogs with congestive heart failure
The application of evidence into practice should take into account multiple factors, not limited to: individual clinical expertise, patient’s circumstances and owners’ values, country, location or clinic where you work, the individual case in front of you, the availability of therapies and resources.
