Furthermore, two MEs with best flux values were selected for bioavailability evaluation after transdermal application over rat’s skin.</p><p><strong>Results: </strong>The results showed that the MEs complies with colloidal systems properties. Also, the developed MEs were stable throughout the study, ideal viscous systems with droplet sizes below 500 nm and isotropic. Besides, FTIR-spectra could reveal the structure of the MEs and encapsulation of atenolol inside the dispersed phase. Moreover, the flux values of atenolol in MEs through rat’s skin varied with different factors such as atenolol concentration, MEs’s composition, and zetapotential. The highest flux value of the developed systems was 243.5±16.3 µg. cm<sup>-2</sup>. h<sup>-1</sup>. Furthermore, the <em>in vivo</em> results showed that using the two tested microemulsions maximum plasma levels of atenolol 5.22±0.43 and 4.06±0.15 mg. ml<sup>-1</sup>at 8.18 and 3.64 h respectively could be achieved.</p><p><strong>Conclusion: </strong>The developed microemulsions can be promise formulations for transdermal administration of atenolol as alternative for oral tablets.</p> ER -
