|---|---|---|---|---|
| Primary | Changes in plasmatic amoxicillin concentrations along time measured by HPLC. | Amoxicillin were extracted from plasma by precipitating plasma proteins with acetonitrile. Amoxicillin plasmatic concentration was accessed every 30 minutes until 3h hours after drug administration and every 2h after this time until 12h of drug administration. Drug plasmatic concentrations were obtained by using a HPLC method. | Change from baseline to 12 hours | No |
