Pharmacokinetic Drug-Drug Interaction Between Bisoprolol and Ivabradine in Healthy Volunteers

The aim of this study is to undergo a pharmacokinetic study to investigate the incidence of potential pharmacokinetic interaction between Ivabradine and Bisoprolol through the Assessment of the drug-drug interactions of Ivabradine and Bisoprolol by determination of pharmacokinetic parameters of both drugs administered alone and in combination. The pharmacokinetic parameters will include; The maximum plasma concentration (Cmax),the time to reach the peak concentration (tmax), area under the concentration-time curve (AUC0-t) and (AUC0-∞) during the treatment periods, the absorption and elimination rate constants (ka and kel), the half-life and mean residence time (MRT). Study design A comparative randomized open-label three-period crossover study of ivabradine/ bisoprolol in male healthy human volunteers Methodology Eighteen healthy volunteer will be recruited in the study and will be divided into three groups each consisting of six volunteers as follows: Period I: * Group A: Six Volunteers will receive single 10 mg oral dose of ivabradin (Procoralan®, Les Laboratoires Servier Industrie-France). * Group B: Six Volunteers will receive single oral dose of bisoprolol 5mg (Concor®). * Group C: Six Volunteers will receive a single dose of ivabradine 10 mg and bisoprolol 5 mg Period II: * Group A: Six Volunteers will receive a single dose of ivabradine 10 mg and bisoprolol 5 mg * Group B: Six Volunteers will receive single 10 mg oral dose of ivabradin. * Group C: Six Volunteers will receive single oral dose of bisoprolol 5mg. Period III: * Group A: Six Volunteers will receive single oral dose of bisoprolol 5mg. * Group B: Six Volunteers will receive a single dose of ivabradine 10 mg and bisoprolol 5 mg * Group C: Six Volunteers will receive single 10 mg oral dose of ivabradin All drug administration will be followed by 240 ml of water after at least 10 h fasting prior to administration. The three treatment periods will be separated by a one week washout period. Standardized meals will be served at 2, 5, and 10 h after drug dosing. All subjects should abstain from the consumption of fruit juices during the study period. Subject Selection Criteria Eighteen adult male volunteers will be enrolled. Subjects should understand the procedures and are willing to participate and give their final written consent prior to the commencement of the study procedures.
