Abstract-
Microcapsule is a tiny sphere including core material/internal phase or fill, coated with/surrounded by wall know as shell, coating or membrane. The usual size range of the microcapsule lies between 1 to 1000 μm. The technique is usually applied for targeted drug delivery, protection of the molecule and stability if the core material. Microencapsulation system offers potential advantages over conventional drug delivery systems and also established as unique carrier systems for many pharmaceuticals. This article contains the traditional and the recent techniques, including their patents, for the preparation of microcapsules. Solvent exchange method, coacervation, polymerization, hot melts etc are several recent techniques are used for the preparation of the microcapsules. The microencapsulation technique, as Novel drug Delivery System (NDDS), is widely applied for delivery of probiotics, drugs, pesticide, food etc. Although significant advances have been made in the field of microencapsulation, still many challenges need to be rectified during the appropriate selection of core materials, coating materials and process techniques.

ABSTRCT:
The present study in formulation and evaluation of 5-fluorouracil microcapsules. 5-fluorouracil which is used as a anti cancer drug to treat cancer. The capsules were prepared by coacervation phase separation and emulsion solvent evaporation by using gelatin, sodium alginate and ethyl cellulose. The prepared microcapsules were evaluated with various evaluation methods such as drug content, in-vitro drug release studies, kinetic studies and stability studies as per ICH guidelines were performed. The formulated extended release microcapsules were prepared by powder layering technique. In these formulations containing 150mg of 5-fluorouracil was loaded in it. The particle size and dissolution study of  F9 formulation was concluded as the best formulation among other formulations, which showing the most desired drug release. It will be considered as optimized formulation. No significant change was observed in the drug content physical properties and dissolution rate of these micro pellets after the storage period of three months at 40±2ºc and 75±5%RH.

ABSTRACTS
The lyophilized wafer developed throughout this review is an effective and versatile drug delivery system for oramucosal application. This has been established from the extensive physicochemical and physic mechanical profiling conducted. Through a screening and selection of polymers, HPC had the lowest gelation characteristics and was therefore suitable for the development of the wafer system. Suitable excipient and polymer combinations were established which allowed for the development of rapidly disintegrating and prolonged release wafer systems. The wafer system containing HPC, lactose, mannitol and glycine had the ability to disintegrate within 30 seconds. The modified wafer system, consisting of pectin cross linked with zinc ions serving as the drug reservoir, and mucoadhesive polymer combination of pectin, carmellose and gelatin, provided effective release of model drug diphenhydramine hydrochloride over approximately six hours. The modification of this technology to provide a prolonged release mucoadhesive system seems promising. It is envisaged that this system will be applicable to many drugs requiring the extended release of bioactive material. Therefore, the lyophilized wafer matrices developed in this study are highly effective in the rapid delivery of drugs, using the oral route as a site of administration.
