Abstract:
Oral controlled drug delivery systems represent the most popular form of controlled drug delivery systems for the obvious advantages of oral route of drug administration. However, there are certain conditions for which such a release pattern is not suitable like cardiovascular diseases, Diabetes mellitus, Asthma, Arthritis, Peptic ulcer etc. In such cases pulsatile drug delivery system is used in which release drug on programmed pattern i.e. at appropriate time & at appropriate site of action. Pulsatile Drug Delivery systems are basically time controlled drug delivery systems in which the system controls the lag time independent of environmental factors like pH, enzymes, gastro-intestinal motility, etc. The principle rationale for the use of pulsatile release is for the drugs where a constant drug release, i.e., a zero-order release is not desired. In chronopharmacotherapy drug administration is synchronized with biological rhythms to produce maximal therapeutic effect & minimum harm for the patient. Technically, pulsatile drug delivery systems administered via the oral route could be divided into two distinct types, the time controlled delivery systems and the site-specific delivery systems, thus providing special and temporal delivery. In recent pharmaceutical applications involving pulsatile delivery; multiparticulate dosage forms (e.g. pellets) are gaining much favor over single-unit dosage forms. Various pulsatile technologies have been developed on the basis of methodologies, these includes ACCU-BREAK™, AQUALON,  CODAS®, PRODAS®, SODAS®, MINITABS®, DIFFUCAPS®, OROS® etc. Designing of proper pulsatile drug delivery will enhance the patient compliance, optimum drug delivery to the target side & minimizing the undesired effects.

Abstract:
The aim of this reviewis to introduce the basic principles of drug targeting as they have evolved over previous decades. The most important chemical features and biological behavioural characteristics of the carrier molecules exploited for drug targeting purposes will be addressed. Furthermore, a selection of drug targeting preparations that are either in the stage of clinical testing or have been approved for application in the clinic is discussed. As the basis of drug development lies in the understanding of the molecular basis of diseases, selective interference with regulatory processes in health and disease by drug targeting will become a powerful technology. Drug targeting can, in this respect, serve both as a therapeutic approach and as a research tool in unravelling the functions of these processes in normal physiology and under patho-physiological conditions.

ABSTRACT:
Now a day about 74% of drugs are taken orally and are found not to be as effective as desired either due to bioavailability problems or degradation of drug in acidic pH of stomach. To resolve such problems, transdermal drug delivery system (TDDS) was emerged. Transdermal drug delivery systems are dosage forms involves drug transport to viable epidermal and dermal tissues of the skin for local therapeutic effect while a very major fraction of drug is transported into the systemic blood circulation. Transdermal drug delivery systems, also known as ‘‘patches,’’ are dosage forms designed to deliver a therapeutically effective amount of drug across a patient’s skin. This review article provides an overview of TDDS, advantages, limitations, various components of TDDS, methods of preparation, types of transdermal patches, factors affecting transdermal permeation, evaluation parameters and new approaches in TDDS.

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.
