ABSTRACT
The basic rationale of sustained release drug delivery system optimizes the biopharmaceutical, pharmacokinetic and pharmacodynamic properties of a drug in such a way that its utility is maximized, side-effects are reduced and cure of the disease is achieved. There are several advantages of sustained release drug delivery over conventional dosage forms like improved patient compliance due to less frequent drug administration, maximum utilization of the drug, increased safety margin of potent drug, reduction of fluctuation in steady-state drug levels, reduction in healthcare costs through improved therapy and shorter treatment period.Presently pharmaceutical industries are focusing on development of sustained release formulations due to its inherent boons.Wide varieties of polymers are available for retarding the release rate of drugs hence sustains the action of drugs. This article contains the basic information regarding sustained-release formulation, its advantages, different types, and characteristics involved in oral sustained-release dosage form design.

ABSTRACT:
Prior studies have suggested that depressed people with evidence of high inflammation are less likely to respond to traditional treatments for the disorder, including anti-depressant medications and psychotherapy. This study was designed to see whether blocking inflammation would be a useful treatment for either a wide range of people with difficult-to-treat depression or only those with high levels of inflammation. The study employed infliximab, one of the new biologic drugs used to treat autoimmune and inflammatory diseases such as rheumatoid arthritis and inflammatory bowel disease. A biologic drug copies the effects of substances naturally made by the body's immune system. In this case, the drug was an antibody that blocks tumour necrosis factor (TNF), a key molecule in inflammation that has been shown to be elevated in some depressed individuals. Study participants all had major depression and were moderately resistant to conventional antidepressant treatment. Each participant was assigned either to infliximab or to a non-active placebo treatment. When investigators looked at the results for the group as a whole, no significant differences were found in the improvement of depression symptoms between the drug and placebo groups. However, when the subjects with high inflammation were examined separately, they exhibited a much better response to infliximab than to placebo.

Abstract
The first and the second generation type of dosage forms had been found to have lower efficacy of drug reaching to the targeted tissue this lead to need for third generation drug delivery system which contains the liposomes, microspheres, microcapsules, nanodiamonds etc. with these type of drug delivery system it had been found to have better patient compliance and reduced side effects. The present paper  deals with the same as there is first formation of Metformin double emulsion and then precipitation of the drug from the polymeric solution. In this study challenge was to encapsulate Metformin with high entrapment efficiency by w/o/o double emulsion solvent diffusion technique using non-aqueous processing media. The primary requirement of this method to obtain microsphere is that selected solvent for polymer must be immiscible with non aqueous processing media, so to fulfill the requirement.

ABSTRACT
Regulatory involvement and environmental concerns are causing pharmacists to take a closer look at how their organizations are managing pharmaceutical waste. Each organization should evaluate its current waste management practices in comparison with state regulatory guidelines. Organizations must then develop a comprehensive plan for full compliance through segregation of waste into the appropriate waste streams. The discovery of a variety of pharmaceuticals in surface, ground, and drinking waters around the country is raising concerns about the potentially adverse environmental consequences of these contaminants. Pharmaceutical waste is not one single waste stream, but many distinct waste streams that reflect the complexity and diversity of the chemicals that comprise pharmaceuticals. Pharmaceutical waste is potentially generated through a wide variety of activities in a health care facility, including but not limited to intravenous (IV) preparation, general compounding, spills/breakage, partially used vials, syringes, and IVs, discontinued, unused preparations, unused unit dose repacks, patients’ personal medications and outdated pharmaceuticals. The consistent increase in the use of potent pharmaceuticals, driven by both drug development and our aging population, is creating a corresponding increase in the amount of pharmaceutical waste generated.

ABSTRACT
The word “Dossier” has its English meaning as - a collection or file of documents on the same subject, especially a file containing detailed information about a person or a topic. Any preparation for human use that is intended to modify or explore physiological systems or pathological states for the benefit of the recipient is called as “pharmaceutical product for human use”. Process of reviewing and assessing the dossier of a pharmaceutical product containing its detailed data (administrative, chemistry, pre-clinical and clinical)  and the permission granted by the Regulatory Agencies of a country with a view to support its marketing / approval in a country is called as the “Marketing Approval  or the “Registration” “Marketing Authorization” or the “Product Licensing”.
“Registration Dossier” of the pharmaceutical product is a document that contains all the technical data (administrative, quality, nonclinical and clinical) of a pharmaceutical product to be approved / registered / marketed in a country. It is more commonly called as the New Drug Application (NDA) in the USA or Marketing Authorization Application (MAA) in the European Union (EU) and other countries, or simply Registration Dossier. Basically, this consists of data proving that the drug has quality, efficacy and safety properties suitable for the intended use, additional administrative documents, samples of finished product or related substances and reagents necessary to perform analyzes of finished product. Therefore, they are the vehicle in a country through which drug sponsors formally propose that the Regulatory Agencies approve a new pharmaceutical for sale and marketing.

Abstract:
New cancer targeted therapies that make use therapeutic antibodies or small molecules have made treatment more tumor specific and less toxic. Nevertheless, there remain several challenges to the treatment of cancer, including drug resistance, cancer stem cells, and high tumor interstitial fluid pressure. In many solid tumors, for example, increased interstitial fluid pressure makes the uptake of therapeutic agents less efficient. One of the most promising ways of meeting such challenges is ligand-targeted therapy that may be used to make targeting more specific and carry higher dosages of anti-cancer drug to tumor tissue.

Abstract:
Herbal medicines are very popular in treatment of the asthma in the modern era because of lots of benefits of it like less cost, less side effects, easily available etc. Herbal alternatives to asthma are better way for treatment of asthma. Various herbal medicines recognize that immune system functioning can play a vital role in helping to control the symptoms of asthma and strengthen the body's defenses against environmental allergens. Herbal medicines like ephedra, ginger, chamomile, elderberry, licorice, mullein, stinging nettle etc are very beneficial in asthma. Scientists have found evidence to support herbal's wide range of medicinal actions. These actions include the lowering of cholesterol levels, relief for allergies and asthma etc. Herbs have been used by people for longer than we have been keeping written record. Originally they were found in the wild by the gatherers and used for lots of different things. I light here, the use of herbals in asthma. It aims to tap into the body’s own healing mechanism by transforming the “triggers” of such attacks as part of the remedy. Opinions of different authors are saying that herbal medication is better way for asthma treatment.
