Primary Outcome Measures
NameTimeMethod
Area Under the Plasma Concentration-time Curve (AUC) From Time Zero to Infinity (AUCinf) of SSP-004184 After One DosePeriods 1 & 2: Within 30 min pre-dose, and Post-dose 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 24, 48, 72, 96, and 120 hrs. Period 3: Within 30 min pre-dose, and Post-dose 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 12.5, 13, 13.5, 14, 14.5, 16, 20, 24, 48, 72, 96, and 120 hrs.

AUCinf is the area under the curve extrapolated to infinity, calculated using the observed value of the last nonzero concentration. AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure how much and how long a drug stays in a body.

Area Under the Steady-state Plasma Concentration-time Curve (AUClast) of SSP-004184 After One DosePeriods 1 & 2: Within 30 min pre-dose, and Post-dose 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 24, 48, 72, 96, and 120 hrs. Period 3: Within 30 min pre-dose, and Post-dose 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 12.5, 13, 13.5, 14, 14.5, 16, 20, 24, 48, 72, 96, and 120 hrs.

AUC 0-last is the area under the plasma concentration versus time curve from time 0 to the time of last quantifiable concentration. AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure how much and how long a drug stays in a body

Maximum Plasma Concentration (Cmax) of SSP-004184 After One DosePeriods 1 & 2: Within 30 min pre-dose, and Post-dose 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 24, 48, 72, 96, and 120 hrs. Period 3: Within 30 min pre-dose, and Post-dose 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 12.5, 13, 13.5, 14, 14.5, 16, 20, 24, 48, 72, 96, and 120 hrs.

Cmax is a term that refers to the maximum (or peak) concentration that a drug achieves in the body after the drug has been administrated

Secondary Outcome Measures
NameTimeMethod
Area Under the Steady-state Plasma Concentration-time Curve (AUClast) of SSP-004184 After Two DosesPeriods 1 & 2: Within 30 min pre-dose, and Post-dose 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 24, 48, 72, 96, and 120 hrs. Period 3: Within 30 min pre-dose, and Post-dose 0.5, 1, 1.5, 2, 2.5, 4, 8, 12, 12.5, 13, 13.5, 14, 14.5, 16, 20, 24, 48, 72, 96, and 120 hrs.

AUClast is the area under the concentration versus time curve from the time of dosing to the last measurable concentration. AUC can be used as a measure of drug exposure. It is derived from drug concentration and time so it gives a measure how much and how long a drug stays in a body.
