Abstract: | The purpose of the present study was to develop and characterize the chitosan sponges loading with doxycycline hyclate and
their antibacterial activities. The pore density of chitosan sponge prepared with freeze drying technique was increased as
the higher concentrated chitosan solution was used. The sponge prepared from 10% w/w of the chitosan solution and crosslinking with glutaraldehyde solution was utilized for loading with doxycycline hyclate.
The drug release and sustainable antibacterial activity of fabricated sponge were assessed using dissolution test and agar
diffusion test, respectively. Drug release from non-crosslinked sponge into phosphate buffer pH7.4 was slower than that from
crosslinked sponge since the former could absorb the medium and form gel to retard the initial drug diffusion. Sustainable
antibacterial activity of developed sponge was evident against S. aureus and E. coli. In conclusion, the in vitro release profile and antibacterial efficiency indicated that doxycycline hyclate could be sustained using chitosan sponge. |
