Pulsatile drug delivery system was developed which have three parts fast dissolving tablet of glimepiride, sustained release chitosan coated microbeads of miglitol and plug of HPMC E5 and spray dried lactose. After preformulation studies fast dissolving tablets were prepared by direct compression method; which shows instant drug release and % CDR of glimepiride fast dissolving tablet was found to be 70.81%. polymer plug have lag time 2.30 hr, chitosan coated miglitol beads shows sustained release upto 81.66% .this system is evaluated using different physicochemical parameters and in-vitro studies. Result suggests that the system can be applicable for diabetes treatment.
