ABSTRACT
The purpose of writing the review on gastroretentive drug delivery systems (GRDDS) was to accumulate the current literature with a special emphasis on several gastroretentive approaches that have recently become important methodologies in the field of site-specific orally administered sustained/controlled release drug delivery. Technological efforts have been made in research and development of rate-controlled oral drug delivery systems to solve physiological difficulties, like short gastric residence times (GRT) and unpredictable gastric emptying times (GET). GRDDS are an approach to prolong the GRT, thereby targeting site-specific drug release in the upper gastrointestinal tract (GIT) for local or systemic effect. Conventional oral dosage forms pose low bioavailability problems because of their quick gastric transition from the stomach, particularly in case of drugs that are less soluble at an alkaline pH of the intestine. Also, drugs that produce their local action in the stomach get quickly emptied and don’t get sufficient residence time in the stomach. Several efforts have been made to extend the retention time of drug delivery system to reduce the frequency of dose administration. GRDFs not only prolong dosing intervals, but also increase patient compliance beyond the level of existing controlled release dosage forms. This article gives an overview on advantages, disadvantages and characterization of gastroretentive drug delivery systems. This review also includes commercially available gastroretentive products and patents.

ABSTRACT
The aim of present investigation was to design and evaluate, mucoadhesive buccal patch of Metformin hydrochloride, a BCS class II drug, to provide unidirectional sustained drug delivery to the buccal mucosa that has potential to enhance the bioavailability. The patches were prepared using HPMC K4M as a polymer, polyethylene glycol 400 as a plasticizer, by solvent casting technique. The patches, which were prepared by the solvent casting method, were smooth and elegant in appearance; were uniform in thickness, weight and drug content; showed no visible cracks; and showed good folding endurance. The amount of polymer, which significantly influenced characteristics like swelling index, mucoadhesive strength, diffusion study

ABSTRACT
This article undertakes a review and assessment of regulatory framework in the Indian pharmaceutical industry. Understanding the regulatory circumstances in this segment is extremely critical. The Pharmaceutical industry is one of the major industries in India and it contributes a large share in the overall macro level growth of the India. It is one of the most dynamic sectors in the country but its compliance structure is more complex. The pharmaceutical industry has always been a buoyant sector in the eyes of Investors. With increasing returns, lower risks and high growth, investors are more interested in this industry than ever before.

ABSTRACT
For several decades pharmacist have been aware of the need to protect their products against microbial contamination but it is only during the last one or perhaps two decades the serious thought of has been applied to the science of preservation. Preservatives are commonly used as additives in pharmaceutical products, food and cosmetics. Some of the liquid preparation are susceptible to microbial contamination because of the nature of ingredients present in it. Such preparation are protected by preservatives which avoids degradation and alteration of the product.A preservative is a natural or synthetic chemical added to various products which helps to prevent microbial decomposition. Present article deals with the study of ideal properties, classification, mechanism of action, Pharmaceutical applications and its impact on health of various preservatives used in pharmaceuticals.

ABSTRACT
A new simple and sensitive RP-HPLC method was developed and validated for quantification of Mebendazole in Active Pharmaceutical Ingredient (API) and pharmaceutical formulation.The gradient RP-HPLC method was developed on Agilent (India) C18 250 × 4.6 mm, 5 μ column using mobile phase as acetonitrile: water pH 3.0 with orthophosphoric acid (90:10 v/v) at a flow rate of 1 mL/min and detection was carried out at 234 nm using UV-Visible detector (UV 3000 M). The method was validated linearity, limit of detection, limit of quantification, precision, ruggedness, robustness, accuracy and specificity were found to be satisfactory. The method was found to be linear in the concentration range of 20-100 μ/mL with correlation coefficient of 0.999. The method was validated according to the ICH guidelines and was proved to be specific, linear, accurate, precise and economical for the analysis of Mebendazole.

ABSTRACT
Good storage of data & record management are critical elements of pharmaceutical quality system. Data integrity refers to maintaining & assuring the accuracy & consistency of data over its entire life –cycle in compliance with its applicable regulatory requirements.
Data integrity is mandatory for the regulated pharmaceutical industry, as processing and disposition decisions regarding product quality, safety, efficacy, purity, and compliance with the applicable regulatory requirements are made based on data that is recorded and reported. Data integrity risk should be assessed, mitigated, communicated & reviewed throughout the data life cycle. Healthcare industries should be designed Record-keeping methodologies and systems, in a way that encourages compliance and assures data quality and reliability.

ABSTRACT
In this current work simultaneous estimation of Moxifloxacin HCL and Ketorolac tromethamine in simulated tear fluid was performed by using UV spectroscopy. The zero order derivative spectroscopy revealed that Moxifloxacin HCL had a λ max of 288 nm in Simulated tear fluid (STF) and Ketotorolac tromethamine had λ max of 322nm respectively. The linearity was found in the range of 2-10 µg/ml for Moxifloxacin HCL and 2-14µg/ml for ketorolac tromethamine.  The R2 value was found to be 0.998 and slope y=0.089 for Moxifloxacin HCL and R2 =0.998 and slope y=0.051 for Ketorolac tromethamine. The zero order spectrum was deravatized to first order derivative spectra for both the above mentioned drug. The first order derivative spectra of Moxifloxacin HCL and ketorolac tromethamine indicated that it had a zero crossing point (ZCP) at 286 nm and 328 nm. The absorbance of the mixture containing MOXI and KETO was found out at 286 nm and 328 nm which showed linearity and obeyed beers lamberts law.

ABSTRACT
Biosensors are a tool that combines the biochemical element with a transducer that generates an indication for the identification of disease. Numbers of biosensors are used in different medical application. Biomarker and Biosensors play an important role for early stage exposure of cancer. It is a cost-effective, increased assay speed, resiliency, the ability for multi-target analysis method. Genomic and proteomic molecular tools are also used for the exposure of tumors. These methods produce a molecular mark that provides a new opening for utilizing biosensors and biomarkers. As with many disease conditions, it is not easy to find exact and responsive markers that are associated with only one marker. Different numbers of molecular signatures are used for the diagnosis of cancer, such as proteins, peptides, overexpression gene and gene mutation. This review provides a general idea of the biosensors and biomarkers technology that is currently developed and researched for cancer markers and diagnosis.

ABSTRACT
Non-ionic surfactant vesicles (Niosomes or NSVS) are widely studied as an alternative to hydrated surfactant monomers. Non-ionic surfactants of wide structural types have been found to be useful alternatives to phospholipids in fabrication of vesicular system. They are the microlamellar structures formed by the mixing of Non-ionic surfactant of alkyl or dialkyl polyglycerol ether class and cholesterol with subsequent hydration in aqueous media. This review article deals with the detailed use of Niosome as novel drug delivery system for ophthalmic use, since this route is most frequently used for the treatment of eye infection.
