What researchers measure

Primary outcomes

  1. Maximum plasma concentration (Cmax) of phenylephrine

    Time frame: 0 hours to time of maximum observed plasma concentration of phenylephrine (blood samples will be collected up to 24 hours after first administration of study treatment)

  2. Time to Cmax (Tmax) of phenylephrine

    Time frame: 0 hours to time of maximum observed plasma concentration of phenylephrine (blood samples will be collected up to 24 hours after first administration of study treatment)

  3. Area under the concentration versus time curve from time 0 to the last measurable concentration (AUC[0-t])

    Time frame: 0 hours to time of last measurable plasma concentration of phenylephrine (blood samples will be collected up to 24 hours after first administration of study treatment)

  4. Area under the concentration versus time curve from time 0 to infinity (AUC[0-∞])

    Time frame: 0 hours to time of last measurable plasma concentration of phenylephrine (blood samples will be collected up to 24 hours after first administration of study treatment)

  5. Terminal rate constant (λz)

    Time frame: 0 hours to time of last measurable plasma concentration of phenylephrine (blood samples will be collected up to 24 hours after first administration of study treatment)

  6. Terminal elimination half-life (t1/2)

    Time frame: 0 hours to t1/2 of phenylephrine (blood samples will be collected up to 24 hours after first administration of study treatment)
