  Purpose
Primary objective:To study the absolute bioavailability, distribution and elimination parameters of flucloxacillin from two oral formulations of flucloxacillin in healthy male and/or female subjects.

Condition Intervention Phase
Infections, Bacterial Drug: flucloxacillin 250 mg Drug: flucloxacillin 500 mg Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Mono-center, Open, Randomized, Three-way, Twelve-sequence, Cross-over Study to Determine the Extent of Absorption (Absolute Bioavailability), Rate of Absorption and to Further Characterize Distribution and Elimination Characteristics of a Commercial 250 mg and a 500 mg Capsule of Flucloxacillin Each Given as a Single Oral Dose vs. One 250 or 500 mg Intravenous Dose to 24 Healthy Male and/or Female Subjects in the Fasting State

Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • Absolute (Abs.) bioavailability, max. plasma conc., concentration-time curve (AUC) from 0 hto the last quantifiable conc., AUC from 0 h to infinity), timepoint of max. plasma conc., Halflife of drug elimination during the terminal phase [ Time Frame: Up to 60 Days ]

Secondary Outcome Measures:
  • Elimination rate constant, total Clearance, Volume of distribution at steady state, Volume of distribution during the terminal phase, residual area [ Time Frame: Up to 60 Days ]
