Abstract:
Novel drug delivery systems have several advantages over conventional multi dose therapy. Recent trends indicate that microparticulate drug delivery systems are especially suitable for achieving controlled or delayed release oral formulations with low risk of dose dumping, flexibility of blending to attain different release patterns as well as reproducible and short gastric residence time. The release of drug from microparticles depends on a variety of factors including the carrier used to form the microparticles and the amount of drug contained in them. Consequently, microparticulate drug delivery systems provide tremendous opportunities for designing new controlled and delayed release oral formulations, thus extending the frontier of future pharmaceutical development. One such approach is using microspheres as carriers for drugs. Microencapsulation is a process where by small discrete solid particles or small liquid droplets are surrounded and enclosed by an intact shell. Microencapsulation is used to modify and delayed drug release form pharmaceutical dosage forms. A well designed controlled drug delivery system can overcome some of the problems of conventional therapy and enhance the therapeutic efficacy of a particular drug. It is the reliable means to deliver the drug to the target site with specificity, if modified, and to maintain the desired concentration at the site of interest without untoward effects. Microspheres received much attention not only for prolonged release, but also for targeting of anticancer drugs to the tumor. The intent of the paper is to highlight the potential of microencapsulation technique as a vital technique in novel drug delivery.

Abstract
With advancements in technology, new inventions are emerging day-by-day, resulting in more number of patent filings all over the globe. The analysis of existing patents to analyze novelty or patentability of upcoming inventions and to check the non-infringing process of the patented technology, there is need to analyze patents of targeted domain technology. The analysis of patents is done not only to analyze novelty or infringement but also to explore the undiscovered innovative knowledge covered in patents. Patent searching using keywords, sometimes, gives very broad results. The analysis of thousands of patents becomes difficult for patent analyst. The methodology used with IPC (International Patent Classification) codes helps to reduce the result of patent search and helps patent analyst in targeted search. But in case of Japanese patent search, IPC alone unable to give targeted results. Then it becomes important to understand the concept of JPC (Japanese Patent Classification) codes and their use to make the Japanese patent search easy. The Japanese Patent Classification includes File Index, Facets and F-term. In this article, Japanese Patent Classification codes are explained in details with their consequences, applications, constructions and search methodology using them.

ABSTRACT
Cinitapride1-2, chemically4-amino-N[3-(Cyclohexan-1-yl-methyl)-4-piperidinyl]-2-ethoxy-5-nitrobenzamide has the molecular formula C₂₁H₃₀N₄O₄ and molecular weight 402.49 g.Cinitapride is a drug that has against action to the serotoninergic 5-HT₂ and D₂ dopaminergic receptors that has been indicated in the gastro esophageal reflux and in the functional disorders of gastrointestinal motility treatment, The present study was aimed to formulate and evaluvate the tablets containing Cinitapride based on floating  technique in order to increase gastric retention time, Total 9 formulation (F1-F9)were done using 3 different polymers like (HPMC k4m, HPMC e15m and HPMC k100m ). The formulations prepared were subjected to dissolution tests for 12 hrs, Among all the 9 formulation  formulation (F5) were able to efficiently control Cinitapride release over a time period of 12 hrs. Thus the results of the current study clearly indicate, a promising potential of the floating tablet as an alternative to conventional dosage form.
