Acute phase reactants are capable of demonstrating the inflammation; however, they cannot be employed to make a difference between bacterial and non-bacterial causes of the inflammation.

Objectives: To prepare DPC by hot melt extrusion method. Physico-chemical characterization of DPC by FT-IR, DSC and XRD studies. To check the superiority of selected superdisintegrants [sodium starch glycolate (SSG), croscarmellose sodium (CCS), crosspovidone (CPV) and sodium carboxymethyl cellulose (SCMC)] in enhancing the dissolution rate of AML from its SLT. To fasten the onset of action, to decrease the hepatic metabolism and thereby increasing AML’s bioavailability in comparison to its conventional tablets. Methods: Standard calibration curve of AML in pH 6.8 phosphate buffer was constructed by spectrophotometric method, drug-excipient compatibility was checked by FT-IR studies. All the Formulations were evaluated for pre& post-compression studies. Accelerated stability studies up to 3 months were conducted for the optimized formulation in a HDPE container pack, as per ICH guidelines. Results and Discussions: Superdisintegrants used in the study are compatible with AML. Pre& postcompression parameters were within the acceptable limits for all formulations. In vitro dissolution kinetic studies indicate the release of AML from SLT increases with the increased concentration of superdisintegrants. The order of superdisintegrants in enhancing the dissolution rate of AML is CPV > SCMC > CCS > SSG. Formulation F3 with 8% w/w CPV, had the highest dissolution efficiency at 10 min (DE10 = 49.80 %); first order dissolution rate constant (K1 = 0.198 min ) with a regression coefficient (r = 0. 956) and lesser time for 50% of drug release (t50 < 6 min), which shows min wetting time of 21.12 sec and min disintegration time of 17 sec, was considered as the optimal SLT. It passed the test for stability as per ICH guidelines. Conclusion: An optimized taste masked AML SLT with the taste masked DPC in combination with the addition of artificial flavor and sweetener was formulated by the direct compression technique, with 8% w/w CPV as superdisintegrant, which will fasten the onset of action and enhances the bioavailability of AML in comparison to its conventional tablets. ⇑ Corresponding author at: Ashok Thulluru, Asstt.

The prevalence of TB is high among the developing world. This retrospective study was carried out to find the incidence and clinical profiles of pulmonary and extrapulmonary tuberculosis patients in North Indian population. \u0000Material and methods: A retrospective analysis of 552 patients having EPTB and PTB was undertaken from the Dept. of Respiratory Medicine, King George’s Medical University, U.P., Lucknow, out of which 300 were of pulmonary tuberculosis and 252 of EPTB. Demographic characteristics, clinical features and apparent risk factors of disease were obtained from medical case records of all patients visiting the hospital from. The Study included only the confirmed cases of EPTB and PTB with or without other co-infections. \u0000Results: Results were tabulated and statistically studied. The prevalence of EPTB was higher among females than males as compared to PTB and this was statistically significant (p=0.001). No significant (p>0.05) association was found between EPTB and PTB according to the place of residence. However, the tobacco habit, smoking habit, alcohol use and family history were found to be significantly (p<0.01) associated with the type of TB. Pleural (62.3%) site of EPTB was a most common site in EPTB patients. The study shows a significant (p=0.04) association between age distribution and disease condition (both EPTB and PTB) among males. A similar observation was found among female patients. The prevalence of EPTB was 1.80 times significantly higher among smokers. The prevalence of EPTB was also higher among those who had a family history of tuberculosis infection in comparison with new cases. Diabetes was present in 16.7% of the EPTB patients and MDR-TB was present in 12.7%. HIV was present in 8%. Most of the patients of EPTB were new cases (88.1) in comparison with the retreatment cases (11.9). \u0000Conclusion: Among evaluated tuberculosis patients, maximum had EPTB. Pleural tuberculosis was the most common presentation of EPTB. Both pulmonary, as well as extrapulmonary forms of tuberculosis, affected the younger population, between 20-40 years of age, more commonly. The study shows female preponderance among EPTB cases as compared to PTB cases. In female population, EPTB affected younger age group as compared to male patients where PTB was found to be more common. A Higher proportion of EPTB cases were found to be HIV positive and suffering from diabetes as compared to PTB.","PeriodicalId":14206,"journal":{"name":"International Journal of Research and Development in Pharmacy and Life Sciences","volume":"78 1","pages":"2773-2778"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88389068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Azithromycin belongs to BCS class II drug i.e. drug with poor solubility and good permeability. The major problems with this drug is its very poor solubility in biological fluids that results into poor bioavailability after oral administration. The objectives of the present research work were to develop the formulation with enhanced dissolution rate of poorly soluble azithromycin. The solid dispersion of azithromycin was prepared using carrier PEG 6000 by melting method. Tablets were formulated containing solid dispersion products and compared with tablet formulated by pure drug without any carrier. The in vitro dissolution studied showed improved dissolution rate and it was compared with in vivo studied using animal model. Dissolution enhancement of the drug being caused by change in crystalline nature of drug in to amorphous nature.","PeriodicalId":14206,"journal":{"name":"International Journal of Research and Development in Pharmacy and Life Sciences","volume":"1 1","pages":"2769-2772"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89840204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In US alone more than one million people are diagnosed with cancer annually and more than half result in death. Cancer is a medical condition where abnormal cells in body divided without any control. Cancers cells do not respond normally to the body’s control mechanism, so they divide excessively and invade the neighboring tissues. Cancer starts when a normal cell is instantly detected by body immune system. However, if the abnormal cells remain at the original site, it will result in the less severe condition termed as benign tumor. Benign tumor can be completely removed by surgery and pose little threat. Malignant tumors have capability to enter the blood stream invading other tissues and disrupting the normal function of various systems in the body. They are difficult to treat may become life threatening. Cancer cells can spread to distinct locations from the original site by a process called metastasis.","PeriodicalId":14206,"journal":{"name":"International Journal of Research and Development in Pharmacy and Life Sciences","volume":"16 1","pages":"2740-2747"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88450361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chromatography is the method by which a mixture is separated into its individual components as a result of the relative ability of each component to be flushed along or through a stationary phase and mobile phase [1-7]. Alumina gel and magnesium hydroxide react chemically to neutralize or buffer existing quantities of acid. It has no direct effect on the production of gastric acid. Gastroscopic observations have shown that alumina gel, if taken undiluted, forms a coating over the inflamed mucosa for a variable period. Oxetacaine is a topical potent anesthetic. Combining Oxetacaine with alumina gel exerts a prolonged topical anesthetic action when applied to mucous membranes Oxetacaine chemically known as (2,2'-(2hydroxyethylimino)bis[N-(1,1-dimethyl-2-phenylethyl)-Nmethylacetamide]) is a potent safe topical anesthetic drug substance having a molecular formula of C28H41N3O3 and a molecular weight 467.64 g/mol(fig.1).

Ethanolic Extract of Crataeva magnaLour. DC (EECM) has been used in traditional and folklore medicine for the treatment of cancer. The aim of the present investigation was to evaluate the effect of ethanolic extract root bark of Crataeva magnaLour. DC in swiss albino mice against intraperitoneally injected Dalton’s ascitic lymphoma (DAL) cell lines. DAL cells were injected intraperitoneally (1×10cells/ml/mouse) to the mice. The EECM at a dose of 200 mg/kg and 400mg/kg body weight were administered orally for 14 consecutive days to the tumor bearing group of animals. Derived parameters, hematological parameters, serum enzyme and lipid parameters were measured and compared to the control group. 5Flurouracil (20 mg/kg) was used as a standard drug. Both doses of EECM decreased average increase in body weight, reduced the packed cell volume (PCV) viable tumor cell count and increased the life span of DAL treated mice and brought back the hematological parameters, serum enzyme and lipid profile near to normal values. All the values were found to be statistically significant with control group at p<0.01. These observations are suggestive of the protective effect of extracts in Dalton’s Ascitic Lymphoma (DAL). All these findings enable to conclude that both doses of EECM possess a protective effect against DAL.","PeriodicalId":14206,"journal":{"name":"International Journal of Research and Development in Pharmacy and Life Sciences","volume":"8 1","pages":"2757-2763"},"PeriodicalIF":0.0,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79473705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
