Abstract

Azithromycin belongs to group II of the biopharmaceutical classification system, its low aqueous solubility explains its
poor bioavailability. The purpose of the present work was to develop a Nano suspension of azithromycin by the solvent
/ antisolvent method to improve its dissolution speed, for this, the influence of the temperature of the dispersion means
was determined. An ethanolic solution of azithromycin (200 mg / ml) was added at a rate of 100 ul / s, on an aqueous
solution of tween 80 (4.5 mg / ml) at 0, 25 and 80°C. Azithromycin nanoparticles of 268.2 nm were obtained, with a
polydispersity index of 0.396, Z potential of -39.6 mV and 94.2% purity. With them, powder was made to reconstitute
oral suspension using hydroxyethyl cellulose as a protective colloid and xanthan gum as a viscosifier. The dissolution
speed of azithromycin nanoparticles is almost 400% higher than azithromycin powder.
