Furosemide (Frusemide) is the prototype loop diuretic in clinical practice with a diuresis that is dose related. Interestingly it is a potent diuretic but some of its effects when given IV are due to the fact that it vasodilates.
- Usual 20-80 mg a day given as a one off morning dose.
- Higher and more frequent doses may be indicated in particular patients.
- Usually given in aliquots of Furosemide 40-50 mg iv
- Ampoules contain 50 mg so most dosing is a multiple of this.
