Abstract
A new Nasal drug delivery system of Domperidone has been developed as decent drug delivery by using natural mucoadhesive agent extract from Tamarindus indica L. The mucoadhesive strength, pH, viscosity and gelling property of this natural mucoadhesive agent was found to be higher in comparison to synthetic polymers, hydroxy propyl methyl cellulose (HPMC) and carbopol which are conventionally used for similar purpose. In vitro drug release characteristic through franz-diffusion cell using excised bovine nasal membrane was also found to be better in comparison to the above synthetic polymers. Now patient friendly, needle free dosage form may replace the Domperidone injections/ tablets in future.

Abstract:
Dendrimers are perfect monodisperse macromolecules(poloymers) with regular and highly branched 3-D structure. Dendrimers have often been referred to as the “Polymer of the 21st century. They are characterized by branch upon branch architecture which are completely different from traditional Polymers. Exceptional feature of a dendrimer includes a high degree of structural symmetry, a density gradient displaying an intra-molecular minimum value and a well defined number of terminal groups. Dendrimers are normally used as carriers for drug delivery especially for oral, ocular and transdermal delivery. Oral drug delivery system are very important to the field of medicine, since most of the common illness are treated via oral route. Encapsulation and conjugation of drug with dendrimers have shown immerse employment for delivery of hydrophobic and labile drugs. Anticancer and antihypertensive drugs are most promising candidates for oral route using dendrimer as carrier. Dendrimers drug delivery system are therefore increasingly viewed as an advantageous for bioactive like drugs and gene. Although dendrimer drug delivery requires attention to certain manufacturing and biological consideration to be successful.

Abstract
Drug product recall is an action taken to withdraw or remove a batch or an entire production run of a drug product from distribution or use and return them to the manufacturer. It is usually done due to the discovery of deficiencies in quality, efficacy or safety in the marketed drug products. Defective drug products related to quality includes adulterated or spurious drugs. Safety and efficacy related recalls include serious adverse reactions and death. Recalls also include drugs prohibited under the law and also those products for which product licenses are suspended/ cancelled. In USA, guidelines for drug product recall are described under 21 CFR Parts 7, 107 and 1270.  In Australia, guidelines for drug product recall are described under section 65F of the Trade Practices Act 1974. Sections 2(2), 4, 5 and 7 of the European Communities Act 1972 and Directive 2001/95/EC on general product safety are followed in UK for drug product recall. In India, references for drug product recalls, complaint and adverse reactions are mentioned in Para 27, 28 of Schedule M and conditions of license for defective product recall in Rule 74(j) and Rule 78(i) of the Drugs and Cosmetics Act, 1940 and Rules there under. But no effective and uniform recall procedure and guidelines are formulated yet in India. This paper presents a comparative study of drug product recall guidelines in USA, UK and Australia. Based on this comparative study suggestions are provided to develop regulatory guidelines for drug product recall in India.

Abstract
Microspheres constitute an important part of novel drug delivery system by virtue of their small size and efficient carrier capacity. Microspheres are characteristically free flowing powders consisting of proteins or synthetic polymers having a particle size ranging from 1-1000 μm. The range of Techniques for the preparation of microspheres offers a Variety of opportunities to control aspects of drug administration and enhance the therapeutic efficacy of a given drug. There are various approaches in delivering a therapeutic substance to the target site in a sustained controlled release fashion. One such approach is using microspheres as carriers for drugs also known as micro particles. 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. Microspheres received much attention not only for prolonged release, but also for targeting of anticancer drugs. The purpose of the review is to compile various types of microspheres, different methods to preparation, its applications and also various parameters to evaluate their efficiency.

Abstract
Insulin remains the most effective and durable hypoglycemic agent for the treatment of diabetes. Insulin is a major protein hormone secreted by beta –cells of the pancreas and is important for the control of diabetes. Insulin has an important place in drug therapies for insulin dependent diabetes mellitus (type I) and for many patients with non-insulin-dependent diabetes mellitus (type II). It would be highly advantageous if insulin could be administered orally, because the oral delivery of insulin can mimic the physiological fate of insulin and may provide better glucose homeostasis. The desire to deliver protein and peptide biopharmaceuticals conveniently and effectively has led to the intense investigation of targeted delivery systems. The goal of oral insulin delivery devices is to protect the sensitive drug from proteolytic degradation in the stomach and upper portion of the small intestine.

ABSTRACT
Oral route is the most preferred route for administration of various drugs because it is regarded as safest, most convenient and economical route. Recently researcher developed the fast disintegrating tablets with improved patient compliance and convenience. Fast disintegrating tablets are solid dosage forms which dissolve rapidly in saliva without chewing and additional water. Fast disintegrating tablets overcome the disadvantages of conventional dosage form especially dysphagia (difficulty in swallowing) in paediatric and geriatric patients. Natural materials have advantages over synthetic ones since they are chemically inert, nontoxic, less expensive, biodegradable and widely available. They can also be modified in different ways to obtain tailor- made materials for drug delivery systems and thus can compete with the available synthetic excipients. With the increasing interest in polymers of natural origin, the pharmaceutical world has compliance to use most of them in their formulations. The natural superdisintegrants can be used instead of synthetic superdisintegrants as they showed equal disintegrating property as that of synthetic agents or dispersible tablets.

Abstract:
Mouth dissolving tablets (MDT) are useful in patients, such as pediatric, geriatric, bedridden, or developmentally disabled, who may face difficulty in swallowing conventional tablets or capsules and liquid orals or syrup, leading to ineffective therapy, with persistent nausea, sudden episodes of allergic attack, or coughing for those who have an active life style. Over the past three decades, mouth dissolving tablets have gained considerable attention as a preferred alternative to conventional tablets and capsules due to better patient compliance The objective of this article is to review the development of MDTs, challenges in formulation,  benefit, limitation ,new MDT technologies and evaluation methodologies.
