    From Day 1 (pledget application) through the final follow-up call at Day 10.

  • Maximum observed plasma concentration (Cmax)

    Measurement of the amount of the study medication (cocaine topical solution) in the blood over 8 hours to define the Cmax.

    Screening Visit, Baseline (pre-dose), 20, 40, 60, and 90 minutes, and 2, 4, and 8 hours after pledget application.

  • Time to maximum observed plasma concentration (Tmax)

    Measurement of the time it takes after dosing for the study medication (cocaine topical solution) to reach its highest observed concentration in the blood over 8 hours.

    Screening Visit, Baseline (pre-dose), 20, 40, 60, and 90 minutes, and 2, 4, and 8 hours after pledget application.

  • Area under the plasma concentration versus time curve from time of dosing (0) to the time of last quantifiable concentration (AUClast)

    Measurement of the amount of the study medication (cocaine topical solution) in the blood over 8 hours to define the AUC.

    Screening Visit, Baseline (pre-dose), 20, 40, 60, and 90 minutes, and 2, 4, and 8 hours after pledget application.

  • Area under the plasma concentration versus time curve from time of dosing (0) to infinity (AUCinf)

    Measurement of the total exposure to the study medication in the blood over 8 hours, starting from dosing and extrapolated to infinity.

    Screening Visit, Baseline (pre-dose), 20, 40, 60, and 90 minutes, and 2, 4, and 8 hours after pledget application.

  • Terminal rate constant in plasma from the negative of the regression line slope through the ln plasma concentration versus time data defining the terminal phase [kel (λz)]

    Measurement of the time it takes for the concentration of the study medication in the blood to decrease by half during the terminal elimination phase, over 8 hours, calculated using kel as ln(2)/kel.

    Screening Visit, Baseline (pre-dose), 20, 40, 60, and 90 minutes, and 2, 4, and 8 hours after pledget application.

  • Terminal half-life in plasma calculated from the kel as ln(2)/kel (t½)

    Measurement of the rate at which the study medication is eliminated from the blood during the terminal phase, calculated from the slope of the log-transformed concentration versus time data.

    Baseline (pre-dose), 20, 40, 60, and 90 minutes, and 2, 4, and 8 hours after pledget application.

Other Outcomes (4)

  • Application Site Assessment

  • Pediatric Smell Wheel

    Screening Visit and 90 minutes post-procedure on Day 1.

  • Assessment of Analgesia and Anesthesia

    Screening Visit and on Day 1 (following pledget removal but prior to procedure).
