Brief Summary

This is an open-label, randomized, single dose, two-sequence two-period crossover study, separated by 7 days washout interval from the first Study Drug Administration. This study is conducted to determine the bioequivalence of cefadroxil from DURICEF™ film coated tablets manufactured by Smithkline Beecham Egypt, LLC affiliated co. to GalaxoSmithKline (GSK) and cefadroxil from BIODROXIL™ film coated tablets manufactured by Kahira Pharm \&Chem .Ind. Co . for Novartis Pharma (NP) after a single oral dose administration of each to healthy adult subjects under fasting conditions. In Period 1, subjects will be randomized to receive cefadroxil tablet manufactured by either GSK or NP. Following a washout of at least 7 days, subjects will be crossed over in Period 2 to receive the cefadroxil tablet that they did not receive in Period 1. DURICEF is a trademark of the GSK group of companies. BIODROXIL is a trademark of Sandoz.

Outcome Measures

Primary Outcomes (2)

• Maximal Measured Plasma Concentration (Cmax) After a Single Dose

  Plasma samples for pharmacokinetic (PK) analysis were drawn at indicated time points of each treatment period. Cmax was defined as maximal measured plasma concentration over the time span specified.

  Pre-dose (0.00) and 0.25, 0.50, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.50, 3.00, 4.00, 6.00, 8.00, 10.00 and 12.00 hours post-dose in each treatment period.

• Area Under the Plasma Concentration-time Curve From Time Zero to the Last Measurable Concentration (AUC0-t) and Area Under the Plasma Concentration-time Curve From Time Zero to Infinity (AUC0-infinity)

  Plasma samples for PK analysis were drawn at indicated time points of each treatment period. Area under the plasma concentration-time curve from time zero (0) to the last measurable concentration (t), as calculated by the linear trapezoidal method. Area under the plasma concentration-time curve from time zero (0) to infinity (AUC0-infinity) was calculated as the sum of the AUC0-t plus the ratio of the last measurable plasma concentration to the elimination rate constant (Ke), where first-order elimination or terminal rate constant calculated from a semi-log plot of the plasma concentration versus time curve. The parameter was calculated by linear least-squares regression analysis using the last three (or more) non-zero plasma concentrations.

  Pre-dose (0.00) and 0.25, 0.50, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.50, 3.00, 4.00, 6.00, 8.00, 10.00 and 12.00 hours post-dose in each treatment period.

Secondary Outcomes (2)

• Time of the Maximum Plasma Concentration (T-max) and Terminal Half- Life (T-half)

  Pre-dose (0.00) and 0.25, 0.50, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.50, 3.00, 4.00, 6.00, 8.00, 10.00 and 12.00 hours post-dose in each treatment period.

• Apparent First-order Elimination or Terminal Rate Constant (Ke)

  Pre-dose (0.00) and 0.25, 0.50, 0.75, 1.00, 1.25, 1.50, 1.75, 2.00, 2.50, 3.00, 4.00, 6.00, 8.00, 10.00 and 12.00 hours post-dose in each treatment period.

Study Arms (2)

Group A

EXPERIMENTAL

Subjects will receive a single oral dose of cefadroxil tablet manufactured by GSK under fasting condition in treatment period 1 followed by 7 days washout interval from the first study drug administration. After the washout interval the subjects will receive a single dose of cefadroxil tablet manufactured by NP under fasting condition in treatment period 2

Group B

EXPERIMENTAL

Subjects will receive a single oral dose of cefadroxil tablet manufactured by NP under fasting condition in treatment period 1 followed by 7 days washout interval from the first study drug administration. After the washout interval the subjects will receive a single dose of cefadroxil tablet manufactured by GSK under fasting condition in treatment period 2
