Abstract:
OBJECTIVE:To prepare buspiron hydrochloride sustained-release tablets and to study its release characterization in vitro and the factors affecting drug release.METHODS:Buspiron hydrochloride sustained-release tablets were prepared with hydroxypropyl methylcellulose(HPMC)as hydrophilic gel-matrix material and ethylcellulose(EC)as retarder by wet granulation.The impacts of releasing transmitters,contents of HPMC and EC,and viscosity on the drug release in vitro of the tablets were studied.RESULTS:For the prepared sustained release tablets,the 24h drug release amount was over 90%,and the drug release curve conformed to Higuchi equation.The more contents of HPMC and EC and the higher viscosity of HPMC in the tablets,the slower drug release velocity was obtained;but the viscosity of EC and the releasing transmitters had no significant impacts on the drug release velocity.CONCLUSION:With HPMC and EC as matrix materials,the 24h continuous drug release is available for buspirone hydrochloride sustained-tablets.
