An Open Label Study to Evaluate the Impact of Duration of Subcutaneous Infusion of a Novel, pH Neutral Formulation of Furosemide (Furoscix®) on Safety and Local Skin Tolerability
An Open Label Study to Evaluate the Impact of Duration of Subcutaneous Infusion of a Novel, pH Neutral Formulation of Furosemide (Furoscix®) on Safety and Local Skin Tolerability
This is a Phase 1 study to evaluate the safety and tolerability of shortened subcutaneous
 infusions of Furoscix.
Furoscix 80 mg will be administered as a subcutaneous infusion following a step-wise decrease
 in infusion times starting with a 5 hour infusion time. Subsequent cohorts will enroll
 following a safety assessment of the prior cohort. While maintaining the 80 mg dose, infusion
 time will ultimately be reduced to 30 minutes.

 with all study procedures.

 4. In the opinion of the investigator, able to participate in the study.
