Study to Determine the Tolerability, Safety and Pharmacokinetics of Ketorolac Tromethamine by Intranasal Administration in Healthy Volunteers

This was a phase 1, open label, multiple dose study in healthy male and female volunteers. Subjects received intranasal ketorolac tromethamine (30 mg) three times daily (t.i.d.) for three days (seven doses in total). Doses were administered every eight hours.

The objective of this study in healthy volunteers was to determine the safety, tolerability, and pharmacokinetics of multiple doses of intranasal ketorolac tromethamine.

Treatment and study plan

Ketorolac Tromethamine

Drug

Subjects received intranasal ketorolac tromethamine (30 mg) three times daily (t.i.d.) for three days (seven doses in total). Doses were administered every eight hours.

Primary outcomes

  1. Cmax (the Maximum Observed Plasma Concentration)

    Time frame: Blood samples for determination of plasma concentration of ketorolac were taken immediately prior to each dose and every hour for 8 hours post-dose on Day 1 (morning doses)

    PK analysis by standard model independent methods was performed by a pharmacokineticist using WinNonlin Professional. Actual blood sampling times were converted to a time from dosing (elapsed time). Elapsed times were listed by subject for each treatment, together with the individual plasma concentrations of ketorolac.

  2. Tmax (the Time to Maximum Concentration)

    Time frame: Blood samples for determination of plasma concentration of ketorolac were taken immediately prior to each dose and every hour for 8 hours post-dose on Day 1 (morning doses)

    PK analysis by standard model independent methods was performed by a pharmacokineticist using WinNonlin Professional. Actual blood sampling times were converted to a time from dosing (elapsed time). Elapsed times were listed by subject for each treatment, together with the individual plasma concentrations of ketorolac.

  3. AUC 0-8h (the Area Under the Plasma Concentration-time Curve From Time 0 to 8 Hours Post-dose)

    Time frame: Blood samples for determination of plasma concentration of ketorolac were taken immediately prior to each dose and every hour for 8 hours post-dose on Day 1 (morning doses)

    PK analysis by standard model independent methods was performed by a pharmacokineticist using WinNonlin Professional. Actual blood sampling times were converted to a time from dosing (elapsed time). Elapsed times were listed by subject for each treatment, together with the individual plasma concentrations of ketorolac.

  4. Cmax,ss (the Maximum Observed Plasma Concentration at Steady State)

    Time frame: Blood samples for determination of plasma concentration of ketorolac were taken immediately prior to each dose and every hour for 8 hours post-dose on Day 3 (morning doses)

    PK analysis by standard model independent methods was performed by a pharmacokineticist using WinNonlin Professional. Actual blood sampling times were converted to a time from dosing (elapsed time). Elapsed times were listed by subject for each treatment, together with the individual plasma concentrations of ketorolac.

  5. Tmax,ss (the Time to Maximum Concentration at Steady State)

    Time frame: Blood samples for determination of plasma concentration of ketorolac were taken immediately prior to each dose and every hour for 8 hours post-dose on Day 3 (morning doses)

    PK analysis by standard model independent methods was performed by a pharmacokineticist using WinNonlin Professional. Actual blood sampling times were converted to a time from dosing (elapsed time). Elapsed times were listed by subject for each treatment, together with the individual plasma concentrations of ketorolac.

  6. Cmin,ss (the Minimum Observed Plasma Concentration at Steady State)

    Time frame: Blood samples for determination of plasma concentration of ketorolac were taken immediately prior to each dose and every hour for 8 hours post-dose on Day 3 (morning doses)

    PK analysis by standard model independent methods was performed by a pharmacokineticist using WinNonlin Professional. Actual blood sampling times were converted to a time from dosing (elapsed time). Elapsed times were listed by subject for each treatment, together with the individual plasma concentrations of ketorolac.

  7. Tmin,ss (the Time to Minimum Concentration at Steady State)

    Time frame: Blood samples for determination of plasma concentration of ketorolac were taken immediately prior to each dose and every hour for 8 hours post-dose on Day 3 (morning doses)

    PK analysis by standard model independent methods was performed by a pharmacokineticist using WinNonlin Professional. Actual blood sampling times were converted to a time from dosing (elapsed time). Elapsed times were listed by subject for each treatment, together with the individual plasma concentrations of ketorolac.

  8. AUCτ (the Area Under the Plasma Concentration-time Curve Over the Dosing Interval at Steady-state)

    Time frame: Blood samples for determination of plasma concentration of ketorolac were taken immediately prior to each dose and every hour for 8 hours post-dose on Day 3 (morning doses)

    PK analysis by standard model independent methods was performed by a pharmacokineticist using WinNonlin Professional. Actual blood sampling times were converted to a time from dosing (elapsed time). Elapsed times were listed by subject for each treatment, together with the individual plasma concentrations of ketorolac.

  9. MRT (the Mean Residence Time

    Time frame: Blood samples for determination of plasma concentration of ketorolac were taken immediately prior to each dose and every hour for 8 hours post-dose on Day 3 (morning doses)
