Abstract:
Selective estrogen receptor modulators, called SERMs for short, blocks the naturally circulating estrogen in breast tissues and other estrogen-sensitive tissues in the body. Each estrogen receptor has a slightly different structure, depending on the kind of cell it is in. If a SERM binds to a estrogen receptor, there is no site available for estrogen to bind and it can't attach to the cell. SERMs are called "selective" because they bind to particular estrogen receptors. This selective binding action is sometimes called estrogen inhibition, or estrogen suppression.

ABSTRACT
The purpose of this research is to design proniosomal powder drug delivery system of flurbiprofen in a trial to overcome the adverse effects associated with oral administration of the drug. Conventional chemotherapy for the treatment of intracellular infection is no more effective due to limited permeation of drug into cell. This can be overcome by the use of vesicular drug delivery system. Encapsulation of a drug in vesicular structure can be predicted to prolong the existence of the drug in the systemic circulation and thus enhance penetration into target tissue and reduce toxicity.Proniosomal powder are generally present in transparent, translucent or white texture, which makes them physically stable during storage and transport. Due to the limited solvent system present, the proniosomes formed were the mixture of many phases of liquid crystal, viz. lamellar, hexagonal and cubic phase liquid crystals.The potential of proniosomes as a transdermal drug delivery system for flurbiprofenwas investigated by encapsulating the drug in various formulations of proniosomal powder composed of various ratios of sorbitan fatty acid esters, cholesterol, prepared by slurry method. The formulated systems were characterized in vitro for size, vesicle count, drug entrapment, drug release profiles and vesicular stability at different storage conditions. Stability studies for proniosomal powder were carried out for 4 weeks. The method of proniosome loading resulted in an encapsulation yield of 30.6 – 75.4%. Proniosomes were characterised by transmission electron microscopy. In vitro studies showed prolonged release of entrapped flurbiprofen. At refrigerated conditions, higher drug retention was observed. It is evident from this study that proniosomes are a promising prolonged delivery system for captopril and have reasonably good stability characteristics.

Abstract
Iontophoresis, a 250 years old technology for delivering the drug is simply based on the use of electrical potential. Being so old, it is still having too popped up just because of its unlimited aspects to work with. In the present review, I tried to compile the vast aspects of a drug delivery system termed as iontophoresis. Iontophoresis is one of the most interesting and challenging endeavors facing the pharmaceutical scientist. The systemic drug delivery systems often require large dose and are associated with gastrointestinal side effects, while topical application of solutions, suspensions, and ointments show variability in absorption patterns. Iontophoresis technique is capable of expanding the range of compounds that can be delivered through ocular, transdermal, ural, transungual, buccal or by nasal route.

Abstract
The goal in designing controlled floating delivery system to reduce the frequency of dosing and / or to increase effectiveness of drug by localization at the site of action, reducing the dose required or providing uniform drug delivery with high bioavailability of buoyant drugs and also reduce the severity and frequency of side effects by maintaining patient blood levels of the drug above the minimum effective level and below the minimum toxic level.
Oral route has been the commonly adopted and most convenient route for drug administration. Oral route of administration has been received more attention in the pharmaceutical field because of the more flexibility in the designing of dosage form than drug delivery, design for other routes.  For sustained drug delivery dosing interval can be extended either by manipulating the drug molecule to reduce the rate of elimination or by altering the release rate of a dosage form to retard the rate of absorption. Both these approaches decrease fluctuating in plasma level in case of multiple dosing extending the dosing interval without under or over dosing.

ABSTRACT
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.
