Bioequivalence Study of Ciprofloxacin in Healthy Adult Subjects Under Fasting Condition
- Conditions
- Healthy Subjects
- Interventions
- Drug: Ciproxin 750 mg
- Registration Number
- NCT05532267
- Lead Sponsor
- Future University in Egypt
- Brief Summary
To evaluate and compare the relative plasma bioavailability and therefore the bioequivalence of two different immediate release products each containing Ciprofloxacin 750 mg, after administering a single oral dose, to healthy adult subjects under fasting conditions.
- Detailed Description
Enrolled subjects were randomized in a two-phase, two-sequence, cross-over design to receive a single dose of the test product (T) or the reference product (R) at each phase, under fasting conditions, with a wash-out period of 7 days.
Ciprofloxacin plasma concentrations were determined using a validated LC-MS-MS method, followed by Pharmacokinetics, and statistical analysis using Phoenix WinNonlin® software to determine the average bioequivalence.
