Summary

This study aims to compare the pharmacokinetics and pharmacodynamics of subcutaneous (SC) and intravenous (IV) furosemide. The test formulation in this study is furosemide injection, 80 mg/1 mL, buffered to a neutral pH for SC administration via an autoinjector. A commercial formulation of furosemide injection, USP, solution 10 mg/mL administered as a 40 mg IV injection over 2 minutes followed by a second dose of 40 mg, 2 hours later, will serve as the reference drug. The objectives of this study are: * To estimate the bioavailability and describe the pharmacokinetics and pharmacodynamics of furosemide administered as SC injection via autoinjector compared with equivalent dose of furosemide administered as two 40 mg IV injections, two hours apart. * To describe the safety and tolerability of furosemide administered as SC injection via an autoinjector.

Detailed description

This is an open-label, single-center, single-dose, randomized, two-way crossover study in healthy volunteers. Each Subject will complete Screening, Baseline, Treatment, and Follow-up Phases. After a Screening Phase, Subjects meeting entry criteria will be admitted to the clinical research unit (CRU) and undergo baseline assessments. Subjects will be randomly assigned in a 1:1 ratio to 1 of 2 treatment sequences (IV furosemide followed by SC or vice versa). Subjects will remain domiciled in the CRU for each treatment period which will be about 12-hours. After final assessments are performed, Subjects may be discharged from the CRU if safety parameters are acceptable to the Investigator and return to the CRU after a 3-day washout period to receive the second treatment sequence. The Follow-up Phase will occur 24-48 hours after discharge from the CRU following treatment sequence 2, completing Subjects' study participation.
