It’s time for bioavailability at home

Increasing fluid overload can reduce the intestinal absorption of diuretics, compromising bioavailability.1-3 Through subcutaneous administration, FUROSCIX is able to deliver at-home, IV-equivalent diuresis with 99.6% absolute bioavailability—even in the presence of fluid overload.1

In an open-label, crossover study

Open-label, crossover study design1:

  • Study subjects represented likely FUROSCIX patients
    • NYHA Class II and Class III chronic heart failure
    • Fluid overload treated with oral diuretics for at least 3 months
  • Patients discontinued oral furosemide at least 24 hours prior to study treatment
  • Patients randomized to either drug, then received alternate treatment after 7-day wash out

Furosemide can cause dehydration and azotemia. If increasing azotemia and oliguria occur during treatment of severe progressive renal disease, furosemide should be discontinued.

Urine output over the periods of 0 to 8 hours and 0 to 24 hours following administration of 80-mg furosemide by 5-hour subcutaneous infusion with FUROSCIX, or IV administration of 2 doses of 40 mg 2 hours apart. Time 0 indicates the start of diuresis therapy.
