Outcome Measures

Primary Outcomes (1)

  • Relative single dose bioavailability (AUC48) of IP (in comparison to SP)

    Relative bioavailability between the investigational products and the standard product (IP1 vs. SP, IP2 vs. SP, IP3 vs. SP, and IP4 vs. SP) expressed as ratio of baseline corrected AUC0-72h, i.e. area under the plasma concentration curve from the administration time to the last observation point (72h) of CoQ10 plasma concentrations above the baseline value.

    72 hours

Secondary Outcomes (1)

  • Relative single dose bioavailability (AUCinf) of IP (in comparison to SP)

    72 hours

Other Outcomes (2)

  • Relative single dose bioavailability (AUC48) among all the investigational products

    72 hours

  • Relative single dose bioavailability (AUCinf) among all investigational products

    72 hours
