What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Area Under the Plasma Concentration Versus Time Curve From Time Zero to Infinity (AUC 0→∞) for Amoxicillin | 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. | Assessed over a 24-hour period starting post-dose on day 4 | 
| Maximum Plasma Concentration (Cmax) for Amoxicillin | 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. | Assessed over a 24-hour period starting post-dose on day 4 |
