Open-label, Single-dose, Randomized, Two-way Crossover Study to Compare the Pharmacokinetics and Pharmacodynamics of Subcutaneous Injection of SCP-111 (Furosemide) vs Intravenous Injection of Furosemide in Healthy Volunteers

Official 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.
