| Maximum Observed Serum Concentration (Cmax) | From hour 0 (pre-dose) to 288 hours post-dose | Cmax is a measure of the maximum amount of drug in the plasma after the dose is given. |
| Time to Maximum Observed Serum Concentration (Tmax) | From hour 0 (pre-dose) up to 288 hours post-dose | Tmax is a measure of the time to reach the maximum concentration in the plasma after the drug dose. |
| Apparent Terminal Half-life (T1/2) | From hour 0 (pre-dose) up to 288 hours post-dose | T1/2 is the time required for a given drug concentration in the plasma to decrease by 50%. |
| Apparent Total Body Clearance (CL/F) | From hour 0 (pre-dose) up to 288 hours post-dose | CL/F is a calculation of the rate at which a drug is removed from the body via renal, hepatic and other clearance pathways, expressed as volume (milliliters) per unit of time (minutes). |
| Apparent Volume of Distribution (Vd/F) | From hour 0 (pre-dose) up to 288 hours post-dose | Vd/F is defined as the distribution of a medication between the plasma and the rest of the body after the dose. It is the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired blood concentration of the drug. |
