Abstract
Captopril is an ACE inhibitor that is used for the treatment of high blood pressure. The reason of this examine became to encapsulate the drug in unique polymer having mucoadhesive belongings and hence combining the benefits of microparticulates with mucoadhesive drug transport device. The microcapsules with a coat which include alginate and a mucoadhesive polymer including sodium carboxymethylcellulose (SCMC), methylcellulose, Carbopol 934P and hydroxyl propylmethylceullulose (HPMC) E15V have been organized through ionotropic gelation method, in which gelation became finished with oppositely charged counter ions to shape microparticles. The organized microcapsules have been subjected for diverse evaluations. The ensuing microparticles had been discrete, large, round and loose–flowing. Captopril release from those microcapsules became gradual and prolonged over longer duration of time. Drug launch for a few formula became diffusion controlled and others exhibited anomalous behavior. The organized microcapsules exhibited correct mucoadhesive belongings in the in vitro wash–off test. Among all formulations, batch containing sodium alginate and carbopol 934 confirmed better encapsulation efficiencies, correct float belongings and most prolongation of drug launch and correct mucoadhesion residences drug release and excellent mucoadhesion residences.
