Objective: To study Analgesic and anti-inflammatory activity of Amarwel extracts on experimentally induce pain and inflammation on animalsMaterials and Methods: Petroleum ether extract, methanol extract, and aqueous extracts of Cuscuta reflexa (PECR, MECR, and AECR respectively) at three dose levels of 50, 200 and300 mg/kg body weight of an animal by oral route were used for biological activities. The analgesic activity of was determined using hot plate analgesia, acetic acidinduced writhing response and formalin test. The anti-inflammatory activity of was determined using models like carrageenan, serotonin and histamine-induced paw edema models along with cotton pellet induced granuloma. Probable mechanism involved in the antiinflammatory effect of methanol and aqueous extracts was evaluated with various tests like ulcerogenicity test; acetic acid induced vascular permeability test, and leukocyte migration test using a single dose of 300 mg/kg orally.
Results: The HPTLC analysis showed presence of quercetin in MECR and AECR (0.121 and 0.071 mg% respectively). Acute oral toxicity test revealed the LD50 of >2 g/kg. PECR, MECR and AECR (200 and 300 mg/kg p.o.) significantly (P<0.05) increased latency against thermal stimulus, decreased the acetic acid-induced writhing responses and licking times of the second phase in the formalin test. Moreover, MECR and AECR (200 and 300 mg/kg p.o.) exhibited significant (P<0.01) antiinflammatory effect against carrageenan and mediator-induced paw edema.
Conclusion: Results suggest significant analgesic and anti-inflammatory effects produced by MECR and AECR.

The oral drug delivery systems exhibit variable and short gastric emptying time, which result in incomplete drug release from the delivery system. This leads to diminished efficacy of administered dose. Floating drug delivery system (FDDS) can retain the dosage form in the gastric region for several hrs. Designing the Floating drug delivery system for prolong gastric retention helps in improving bioavailability and improve solubility of the drug that are less soluble in a high pH environment. FDDS applicable for drugs having poor bioavailability because of narrow absorption window in the GIT. FDDS increase the bioavailability of drug by retains the dosage form at the site of absorption. This review mainly focus on information on the basis o their design, classification, advantages, evaluation and future scope of FDDS.Keywords

Orally fast dissolving films are an emerging technology with fast onset of activity and improved patient compliance. It enhances the viability of API's and gives better medication use. These formulations are suitable for cold, allergy rhinitis, asthma attacks, CNS issue where fast onset of activity is needed for quicker help. The sublingual course of medication organization is extremely compelling following the medication retained through the sublingual veins by passes hepatic first pass metabolic procedure and also gives a better bioavailability. The present article outlines the definition viewpoints, manufacturing methods like solvent casting method, evaluation parameters and applications of fast dissolving films by sublingual route It has been estimated that approximately 84% of all sales of the top selling commercially available products are delivered via the oral route. Thin film drug delivery has come forward as an advanced alternative to the traditional tablets, capsules and liquids frequently associated with prescription and OTC medications. Similar in size, shape, and thickness to a postage stamp, thin film strips are classically designed for oral administration, with the user placing the strip on or under the tongue(sublingual)or along the inside of the cheeks(buccal).These drug delivery options allows the medication to bypass the first pass metabolism thereby making the medication further available. As the strip dissolves, the drug can enter the blood stream enterically, buccally or sublingually. The permeation is superior with sublingual than buccal than palatal region.Keywords

Many of the newly invented drugs are poorly soluble and they create major problems during formulation and shows poor bioavailability. The problem is even more complex for drugs which belong to BCS class 2 category. To overcome these problems nanotechnology is used to improve the solubility as well as bioavailability of poorly soluble drugs. The reduction of drug particles into submicron range leads to a significant increase in dissolution rate and therefore enhances bioavailability. Nanosuspension contains submicron colloidal dispersion of the pharmaceutical active ingredient particles in a liquid phase stabilized by surfactant. Nanosuspension can be prepared by using stabilizers, organic solvents and other additives such as buffers, salts, polyols, osmogent and cryoprotectant. Nanosuspensions can be delivered by oral, parenteral, pulmonary and ocular routes. Nanosuspensions not only solves the problem of poor solubility and bioavailability but also alter the pharmacokinetics of the drug and thus improving safety and efficacy. This review article mainly focuses on preparation of nanolsuspensions by various techniques with their advantages and disadvantages, formulation consideration, characterization and their applications in drug delivery.Keywords

Chewing gum has been used for centuries to clean the mouth or refresh the breath. Chewing gum was patented for first time on filed in 1869 and the first medicated chewing gum was commercially made available 1928. In 1991 The European Pharmacopoeia defines medicated chewing gum as ''solid, single-dose preparations with a base consisting mainly of gum that are intended to be chewed but not swallowed''. Chewing gum is an excellent drug delivery system for self-medication as it is convenient and can be administered discretely without water or any other liquid. Basics of the gum formulation, quality control tests, regulatory and safety issues have been addressed to ensure desired therapeutic effects. The release of a drug from chewing gum is dependent upon its water solubility. Water soluble substances are released rapidly and completely from chewing gum and methods are available which retard their release from chewing gum to provide an extended release profile. Slightly water soluble drugs are released slowly and incompletely from chewing gum and require special formulation techniques to produce a satisfactory release profile.Keywords

Protein tyrosine phosphatases (PTPs) catalyze the dephosphorylation of tyrosine-phosphorylated proteins and are negative regulators of tyrosine kinase receptor mediated signaling. PTP1B directly interacts with both the IR and IGF- 1R. The importance of PTP1B inhepatic metabolism has been demonstrated in vivo and incellular models. Mice lacking the ptpn1 gene exhibit increased insulin sensitivity owing to enhanced phosphorylation of IR in liver and skeletal muscle, resistance to weight gain on a high-fat diet, and an increased basal metabolic rate. So it is a potential therapeutic target for insulin resistance associated with obesity and type 2 diabetes. To date, studies of PTP-1Bhave been limited by the availability of specific antagonists. Here we investigate a series of 2, 5-disubstituted oxadiazole as novel PTP1B inhibitor. We synthesized few compounds from 2, 5-disubstituted oxadiazole series and screened for the PTP1B inhibition. Compound 9exhibited significant inhibitory activity against PTP1B. Compound 9 showed IC50 value of 0.46 μmol/L and favorable pharmacodynamics properties in mouse. Structure-activity relationships were explained with the help of molecular modeling approach.Keywords

Conventional oral drug delivery systems supply continues release of drug, which cannot release of the drug and effective concentration at the target site. Drug can be delivered in a controlled manner over a long period of time by the process of osmosis. Osmotic devices are the most promising technique for controlled drug delivery. Osmotic drug delivery system is one among the controlled drug delivery employed orally and also as an implantable devices. Various patents available for osmotic drug delivery system like Rose-Nelson pump, Higuchi leeper pump, Higuchi Theeuwes pump, Elementary Osmotic pump etc. various techniques available for preparation of Osmotic Drug Delivery System include Push pull osmotic pump, Osmotic bursting osmotic pump, Liquid oral osmotic system, Sandwiched osmotic tablets, monolithic osmotic system and Controlled porosity osmotic pump. The present review is concerned with the study of drug release system which are tablets coated with walls of controlled porosity. When these system are exposed to water, low levels of water soluble additives is leached from polymeric material i.e. semi permeable membrane and drug releases in a controlled manner over an extended period of time. Drug delivery from this system is not influenced by the different physiological factors within the gut lumen and the release characteristics can be predicted easily from the known properties of the drug and the dosage form. In this paper, various type of osmotically controlled drug delivery systems and mainly the basic components and evaluation parameter of controlled porosity osmotic pump tablets have been discussed briefly.Keywords

It is suggested here that liquisolid technique has the potential to be optimized for the reduction of drug dissolution rate and thereby production of sustained release systems is possible. In the present study, carvedilol was dispersed in polyethylene glycol 400 as the liquid vehicle. Then a binary mixture of carrier-coating materials ((Avicel PH-102) as the carrier and silica200 as the coating material) was added to the liquid medication under continuous mixing in a mortar. The final mixture was compressed using the tablet compression machine. The effect of drug concentration, loading factor, thermal treating and on release profile of carvedilol from liquisolid compacts were investigated. The release rate of carvedilol from liquisolid compacts was compared to the release of carvedilol from matrix tablets. X-ray crystallography and DSC were used to investigate the formation of any complex between drug and excipients or any crystallinity changes during the manufacturing process. carvedilol tablets prepared by liquisolid technique showed greater retardation properties in comparison with matrix tablets. This investigation provided evidence that (HPMC) hydroxypropyl methylcellulose has important role in sustaining the release of drug from liquisolid tablets. The results also showed that wet granulation had remarkable impact on release rate of carvedilol from liquisolid compacts, reducing the release rate of drug from liquisolid compacts. The results showed that aging (liquisolid tablets were kept at 400C and 75 % relative humidity for 3 months) had no effect on hardness and dissolution profile of drug. The kinetics studies revealed that most of the liquisolid formulations followed the zero-order release pattern. Infrared spectroscopy and DSC ruled out any changes in crystallinity or complex formation during the manufacturing process of liquisolid formulations.Keywords

Sharpless enantioselective epoxidation of achiral primary allyl alcohols is one of the best reaction discovered during the last about three decades. The reaction was typically named after discovery of this by Karl Barry Sharpless. For this discovery Sharpless received the Nobel Prize for medicinal chemistry in the year 2001. This reaction is stearoselective, i.e. it produces only enantionmers as final product. This reaction converts primary and secondary allylic alcohols into the 2, 3 epoxy alcohols. The final enantionmers which is formed will be a stereoselective depending upon the catalyst used during the same reaction. This reactions turns to be industry beneficial due to its applicability and high yield of products in the reaction.Keywords

Selective estrogen receptor modulators are the class of a chemical compounds acting on a estrogen receptors. These are selectively inhibit or stimulate the estrogen like actions in various tissues. SERMs play a key role in breast cancer chemoprevention. These agents antagonize estrogens in some tissues and mimic their action in others. The mechanism for tissue selectivity appears to be related to differences in their molecular and three-dimensional structures, which affect the transcriptional activity of the activated estrogen receptor. For example, tamoxifen and toremifene act as estrogen antagonists in breast tissue and as estrogen agonists in the endometrium. The present review article is directed towards highlighting the importance of SERMs in treatment of breast cancer.Keywords
