Bioavailability study of a new amoxicillin tablet designed for several modes of oral administration

A new tablet of amoxicillin (Flemoxin solutab) has been formulated with galenic properties which allow it to be taken as a tablet, either swallowed, chewed or sucked, or to be taken after dispersion in water. This study was undertaken to compare the bioavailability of the new tablet (swallowed as such, or after dispersion) with a commercially available amoxicillin capsule and, for purposes of internal reference, with a Flemoxin forte suspension. Each formulation was administered to 12 volunteers according to a repeated 4 X 4 latin square design. Statistical analysis revealed that the tablet and suspension formulations tested gave significantly higher maximum plasma levels, occurring significantly faster after intake, when compared to the capsule. Furthermore, the new tablet showed a statistically significantly greater area under the plasma concentration-time curve with a highly predictable absorption when compared to the capsule. The method of intake of the new tablet appeared to be of no relevance with respect to the observed bioavailability.
