ABSTRACT
Diabetes a chronic (lifelong) disease marked by high levels of sugar in the blood. Diabetes is a common disease in older age, affecting about one in five individuals. In 2000, according to the World Health Organization, at least 171 million people worldwide suffer from diabetes, or 2.8% of the population. Its incidence is increasing rapidly, and it is estimated that by 2030, this number will almost double. Diabetes is also associated with mortality and significant morbidity, including neurological disability. Diabetes affects both peripheral nervous system and central nervous system. Neuropathy along with retinopathy and nephropathy appears in late stage of diabetes but effect on cognition starts in early stage of diabetes. Although the effects of diabetes on the peripheral nervous system are well established, the effects of diabetes on the central nervous system have been less clear. Several studies have found that diabetes is related to dementia and cognitive function. It is unclear in which stage of diabetes the cognitive decrements become manifest and how they progress over time. Study is conducted to confirm the association of cognitive function with diabetes.

ABSTRACT:
In this review article, we discussed abouteffluent testing and treatment in pharmaceutical industry,Biological treatment of wastewater is frequently the most beneficial method for selecting various toxic compounds from the environment. Most of the organic compounds in industrial wastewaters are of natural origin and can be degraded by common bacteria in aerobic or anaerobic processes. The composition of these wastewaters is very variable. A great variety of organic chemicals can be determined among the principal components of these types of wastewaters. Antibiotics are the major group of pharmaceuticals. Among all the other pharmaceutical drugs and substances, antibiotics are important compounds due to its serious irreversible increase the release to the environment^{[1][2][3][4][5]}

ABSTRACT
The purpose of this research was to formulate and systemically evaluate in-vitro and in-vivo performances of mucoadhesive Ramipril microspheres for its potential use in the treatment of hypertension, myocardial infraction. Ramipril mucoadhesive microspheres, containing chitosan as mucoadhesive polymer and ethyl cellulose as carrier polymer, were prepared by an emulsion-solvent evaporation technique. Preformulation studies were carried out before formulation design. Total seven formulations were prepared.Microspheres were discrete, spherical, free-flowing and showed a good percentage of drug entrapment efficiency. An in-vitro wash off test showed that Ramipril mucoadhesive microspheres adhered more strongly to the gastric mucous layer and could be retained in the gastrointestinal tract for an extended period of time. In-vitro dissolution test was carried out by using phosphate buffer pH 6.8. All the formulations showed good dissolution profiles. Among all the formulation F5 showed good dissolution profile with 81.0% of drug release in 12 hours. In-vitro release kinetic data of Ramipril microspheres showed that the drug release mechanism was diffusion controlled as the plots of Higuichi model was linear. All formulations exhibited Non-Fickian diffusion (n value is in between 0.5 to 1) mechanism. Stability studies were done for the selected formulation indicates that there is no change in drug content of the formulation.The results showed a sustained anti-hypertensive effect over a longer period of time in case of mucoadhesive microspheres, compared to the powder. In conclusion, the prolonged gastrointestinal residence time and slow release of Ramipril resulting from the mucoadhesive microspheres, could contribute to the provision of a sustained anti-hypertensive effect.

ABSTRACT:
The aim of this study was to evaluate the effect of increasing nifedipine on the characteristics of fast-disintegrating sublingual tablets for the potential emergency treatment of anginal pain and hypertension. Nifedipine undergoes first pass metabolism in liver and gut wall which has oral bioavailability of 43-77%. Sublingual dosage form bypasses the metabolism of the nifedipine in liver and offers a fast relieve from anginal pain and hypertension. An attempt has been made to prepare fast dissolving tablets of nifedipine were prepared by wet granulation technique using Crospovidone and croscarmellose sodium (CCS) as super disintegrants as super disintegrants, Flavor and sweetener impart the taste to the formulation. The porous granules were compressed in to tablets by 8mm punch rotary tablet machine. All the formulations were evaluated for weight variation, hardness, friability, content uniformity, wetting time, and disintegration time and dissolution rate. Among the formulations, F9 one containing to be the best acceptable in terms of palatability, fast dissolving tablet having adequate strength. The disintegration time was found to be 56 ± 0.4 seconds, hardness of 4.6 ± g /cm², wetting time of 31sec   and drug release of 99.85 % in 9 mins. All the formulations showed low weight variation. The present study demonstrated potentials for rapid absorption, improved bioavailability, effective therapy and patient compliance.

Abstract:
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.

Abstract:
“Paclitaxel” is a potent mitotic inhibitor acting as anti-neoplastic agent, obtained as complex diterpins, termed “Taxanes” from the barks of Taxus breufolia (Pacific Yew). The oral bioavailability of the drug varies around 6-7% and has a strong protein binding capacity altering between 89% - 98%. Most of these drugs have a central role in metastatic ovarian and breast carcinoma, along with advanced head and neck cancer, small cell lung cancer, esophageal adenocarcinoma, hormone refractory prostate cancer, Kaposi’s Sarcoma and also in the prevention of recurrent narrowing of Coronary Stents. Paclitaxel mainly functions by improvising enhanced stabilization of microtubule polymers during cell division and binds specifically to the beta-tubulin subunits, thus antagonizing disassembly of the key cytoskeletal protein, producing abnormal arrays of microtubules throughout the cell cycle.  Due to the poor aqueous solubility there is a need for the development of alternative formulations of paclitaxel with improved solubility and at the same time devoid of major toxic effects. Various approaches employed so far include cosolvents, emulsions, micelles, liposomes, microsphere nanoparticles, cyclodextrins, pastes, and implants. All these formulations have been prepared with specific aims to enhance bio-stability and  reduce the basic toxic effects of Paclitaxel including low blood count, hair loss, peripheral neuropathy, anthralgias , myalgias, nausea, vommiting,  mouth sores and various hypersensitivity reactions . The drug undergoes extensive CYP-mediated hepatic metabolism (majorly CYP2C8 with specific contributions from CYP3A4), and not more than 10% of a unit dose is excreted in the urine intact. We have tried to answer the probable mechanisms of Paclitaxel and how it can be made more bio-available in order to enhance its anti-cancer activities. Our review revealed the active ingredients that are co-administered with paclitaxel did not improve its functions but blocked the pathways that decreased the function of paclitaxel, since P-glycoproteins itself reduces the accumulation of paclitaxel and might use it as a substrate.

ABSTRACT
Diabetes mellitus is a chronic and potentially disabling disease which is like a sleeping giant that is ready to awaken and literally sink our health care system. The present study “Pharmacoeconomic evaluation of anti-diabetic therapy” was carried out with an objective to assess estimated direct medical cost of diabetes and its complications. A hospital based prospective observational study was conducted using a prevalence based ‘cost of illness’ method focusing on estimated direct health care cost of diabetes and its complications. A total of 108 type 2 DM patients were enrolled into the study out of which 68 (62.96%) were males and 40 (37.04%) patients were females. The results revealed that, the average cost was the highest for the age group 45-60 years. The costs for patients with complications were substantially higher than those without complications and the costs were found to increase progressively with the increase in number of complications. The study concludes that Diabetes with complications resulted about 2.5 times higher cost, therefore the burden of diabetes and its complications was significant for individual and families, keeping in mind the burden of the disease on individuals as well as the society, the health policy makers should emphasize on initiatives to prevent the disease prevalence, care and counseling to diabetes patients should be done continuously to prevent the progression of the disease and its devastating complications.
