Oral disintegrating tablets (ODTs) have received ever-increasing demand during the last decade, and the field has become a rapidly growing area in the pharmaceutical industry. Upon introduction into the mouth, these tablets dissolve or disintegrate in the mouth in the absence of additional water for easy administration of active pharmaceutical ingredients. The popularity and usefulness of the formulation resulted in development of several ODT technologies. This review describes various formulations and technologies developed to achieve fast dissolution/dispersion of tablets in the oral cavity. In particular, this review describes in detail FDT technologies based on lyophilization, molding, sublimation, and compaction, as well as approaches to enhancing the ODT properties, such as spraydrying, moisture treatment, sintering, and use of sugar-based disintegrants. In addition, taste-masking technologies, experimental measurements of disintegration times, and clinical studies are also discussed.

Diclofenac is currently the eighth largest-selling drug and the most frequently used NSAID (Non-steroidal anti-inflammatory drug) in the world, since its introduction in Japan in 1974. Diclofenac is among the better tolerated NSAIDs. Only major adverse effect of Diclofenac is that it causes direct and indirect irritation of the gastrointestinal tract (GIT). To reduce the side effects on gastrointestinal tract (GIT) and to improve therapeutic efficacy of Diclofenac, it can be formulated in polymeric microspheres.
The use of polymeric carriers in formulations of therapeutic drug delivery systems has gained widespread application, due to their advantage of being biodegradable and biocompatible. Among the microparticulate systems, microspheres have a special importance since it is possible to target drugs and provide controlled release. Diclofenac sodium (DS), is a potent drug in the NSAID group having non-steroidal, anti-inflammatory properties, and is widely used in the treatment of rheumatoid arthritis, osteoarthritis and ankylosing spondylitis. In this present study, it was aimed to prepare microsphere formulations of DS using a natural biodegradable polymer as a carrier for administration to extend the duration period of the dosage form. Microsphere formulations of DS which were prepared were evaluated in vitro for particle size, yield value, encapsulation efficiency, surface morphology, and in vitro drug release.

Viruses are pathogens with an extremely narrow host range. Their phylogenetic origin is vague, tough it has always been considered that viruses are genes that became vagrant after having excluded themselves of the host’s or a related species’ genome (Anderson et.al., 2004). Viruses are usually units consisting of nucleic acids and coat proteins called capsids. Viroids consist only of RNA, i.e. they contain no protein at all. Except for a few cases, Viruses have no energy metabolism of their own. Consequently, they cannot perform syntheses and are thus unable to replicate themselves. Depending on their host species, it is distinguished between plant viruses multiplying almost exclusively within plant cells, bacterial viruses (bacteriophages) that depend on living bacteria, and animal viruses. The genetic information of viruses is either encoded by single-stranded RNA (Most plant viruses), double-stranded RNA (Wound tumor viruses), single-stranded DNA (Gemini viruses) or double stranded DNA (Cauliflower mosaic virus). Based on the shape of the viruses particle, it is distinguished between rod shaped and icosahedral viruses with a capsid that seem almost spherical. Viruses’ cause many disease in humans of international importance for example smallpox polio, hepatitis etc. viruses cause also many important plant disease and are responsible for huge loss in crop production and quality in all part of the world. Around 25 years ago, when genomic properties of geminiviruses were studied, many scientists regarded them as ‘friends of humans’, because of their potential as gene transfer vectors in plant genetic engineering and non-harmful effects on host plants. But far from being friends, these viruses have now emerged as foes and are a serious threat to world agriculture now. Increase in international commodity trade, intercontinental transportation networks and a changing global climate have contribute to the spread of this virus and its whitefly vector (Moffat et.al.,1999).
The spark for launching professional education (Management & Pharmacy), both at the undergraduate and post-graduate level at Lloyd has come from Academicians and Business Leaders who felt that the current trend in higher education is only limited to Books, Classes and Exams, that needs to be replaced by more meaningful education so that students are mounded to not only become better professionals but also good human beings at a relatively young age..

Cognitive deficits have long been recognized as severe and consistent neurological disorders associated with numerous psychiatric and neurodegenerative states such as Alzheimer’s disease. Dementia is one of the age-related mental problems, and a characteristic symptom of Alzheimer’s disease. Alzheimer’s disease (AD) is a progressive neurodegerative disorder which affects older individuals and may progress to a totally vegetative state. Atrophy of cortical and sub-cortical areas is associated with deposition of β-amyloid protein in the form of senile plaques and formation of neurofibrillary tangles. There is marked cholinergic deficiency in the brain, though other neurotransmitter systems are also affected. Various measures to augement cholinergic transmitter in the brain have been tried. The relatively cerebroselective anti-ChEs have been approved for clinical use. Nootropic agents are clinically used in situations where there is organic disorder in learning abilities and for improving memory, mood and behavior, but the resulting side-effects associated with these agents have made their utility limited. Many experimental models are currently available for the evaluation of agents that affect learning and memory processes. In-vitro methods inhibition of acetylcholinesterase activity is measured by determining IC50 with the help of Log probit analysis. In ex-vivo cholinesterase inhibition method the dose response relationship determined for drugs such as physostigmine and tacrine Agents which are H3 receptor agonist are evaluated for [3H] Ach release activity in rat using rat brain slices. The binding affinity of potential nicotinic cholinergic agonist in brain using agonist ligand is determined by [3H]-N- methyl carbamylcholine binding nicotinic cholinergic receptors in rat frontal cortex. In In-vivo methods the inhibitory passive avoidance the test are carried on animals to test the learning and memory capacity of animal by suppressing a particular behavior. It includes step down, step through, two compartment test, up-hill avoidance, scopolamine induced test, and ischemia induced amnesia, memory impairments in basal forebrain. In active avoidance conditioned stimulus is given to the animal, which gives noxious stimulus as a result. It includes runway avoidance, shuttle box avoidance, jumping avoidance. In discrimination learning animals have no choice between the conditioned stimuli. Studies on aged monkeys provides additional advantage for neurobehavioral animal model of aging in that many of behavioral processes thought to be affected by aging.

Technological attempts have been made in the research and development of rate-controlled oral drug delivery systems to overcome physiological adversities, such as short gastric residence times (GRT) and unpredictable gastric emptying times (GET). Conventional oral dosage forms pose low bioavailability problems due to their rapid gastric transition from stomach, especially in case of drugs which are less soluble at alkaline pH of intestine. Similarly, drugs which produce their local action in stomach get rapidly emptied and do not get enough residence time in stomach. So, frequency of dose administration in such cases is increased. To avoid this problem, various efforts have been made to prolong the retention time of drug delivery system. In this review, we will discuss about the various approaches to produce gastro retention of drug delivery system, with current & recent developments of Stomach Specific floating drug delivery system.
The United Group, founded by late Shri Shiv Ram Das Gulati in 1951 emerged from a transport business to the giants in the fields of education, services, transportation and journalism. The group made a mammoth leap in the education arena in the mid 80s by being the pioneers in computer education. This further lead to the establishment of United Institute of Management and United College of Engineering & Research in Allahabad.
