ABSTRACT

Now a days Diabetes is a dreadful disease which alter the metabolism of carbohydrates, proteins and fatty acids. Most commonly occurring type is non-insulin dependent diabetes mellitus which may affect 90-95% of the people. Incretins are becoming popular these days. Incretins are gut hormones secreted in response to food. They mainly increase the secretion of insulin. Now a days Incretin mimetics, DPP- IV inhibitors are used in the treatment of type-2 diabetes. However, many oral hypoglycemics are available, but still there is a need to overcome the problems associated with oral hypoglycemics.

ABSTRACT

The aim of present work was to develop fast dissolving tablets of Valsartan by direct compression method using different binders such as acacia, sucrose, starch, gelatin, hydroxypropyl methylcellulose (HPMC) H7509, and Polyvinyl-pyrrolidone (PVP). During the compression of tablets, binders keep the composition of these fast dissolving tablets together. The right selection of binder or combination of these is essential to maintain the integrity and stability of the tablet. The prepared tablets were evaluated for parameters such as hardness, friability, drug content, weight variation, wetting time, water absorption ratio, in-vitro disintegration time, in vitro dissolution studies and stability studies. The study reveals that formulations prepared by direct compression (F5) exhibits better dissolution (90.57%) with lowest disintegration time (40 seconds) containing sucrose as binding agent.

ABSTRACT

The main objective of the present work was to formulate fast-dissolving tablets of an antiemetic drug using natural (xanthum gum, Isapgula husk and banana powder) and synthetic (crospovidone and croscarmelose) superdisintegrants by direct compression method and compare their effect on tablet formulations. This study was also aimed to find out the best superdisintegrants for the prepared formulations with better disintegrating property and better in-vitro dissolution profile. The infra red spectra of pure drug with different excipients showed no shift in peak, hence no interaction between drugs and excipients. The tablets were subjected to the various parameters like weight variation, hardness, thickness, friability, dispersion time, disintegration time, drug content and in-vitro drug release. All the powder blend showed good to acceptable flow ability as the powder blends showed angle of repose below 30°, bulk density in the range between 0.486 to 0.522 g/cm3, tapped density in the range between 0.568-0.590 g/cm3, and the compressibility index was found to be between 12.71 and 14.98 which ensures the powder blends may be suitable for direct compression. In vitro disintegration time for all formulation batches i.e. F1 to F15 showed wide variation in the range between 23 to 36 seconds. Percentage drug content for all tablets were in between 94.4 to 97.25%. In vitro dissolution study for all tablets was performed and formulation F11 containing Isapgula husk as natural superdisintegrants showed 97.25% drug release within 8 minutes, which might be due to swelling ability of Isapgula husk.

ABSTRACT

Ulcerative colitis is a chronic-relapsing, progressive inflammatory bowel disease characterized by diffuse mucosal inflammation of the colon. Repeated damage and injury of the intestinal surface are key features of inflammatory bowel disease. It can be concluded that sitagliptin is partially effective for treatment of experimentally induced ulcerative colitis model in mice. Furthermore, it can be also concluded that effects of simvastatin treatment were mostly dose dependantfor treatment of experimentally induced ulcerative colitis model in mice. Thus, the aim of this study is to evaluate effect of combination of sitagliptin and simvastatin as an early treatment of experimentally induced ulcerative colitis in mice. Furthermore in this study, effect of large dose of either sitagliptin or simvastatin will be compared with combination of both drugs. Thirty mice were equally divided into the following groups: control group, non-treated DSS-induced colitis group, DSS-induced colitis mice treated with simvastatin(50mg/kg/d)group, DSS-induced colitis mice treated with sitagliptin (100 mg/kg/day) group, DSS-induced colitis mice treated with sitagliptin (20mg/kg/d) combined with simvastatin (5mg/kg/d) group. Combination of sitagliptin 20 mg/kg/d + simvastatin 5 mg/kg/d produced a significant decrease in serum TNF-α, colonic tissue MDA & NO levels.Furthermore, reduced glutathione was significantly increased up to near normal level. As regard colon length, it returned to nearly normal length. Combination of small dose of both drugs showed 66% decrease in DAI. This combination restored normal histological appearance of the colon. This is a very good combination as regards to their small doses and consequently less adverse effects.

ABSTRACT

Preeclampsia is a syndrome occurring in pregnancy that affects multiple systemic functions and leads to increased maternal and foetal morbidity as well as mortality. Ischemia Modified Albumin is a well-known marker of cardiac Ischemia. We aimed to test the hypothesis that variation in maternal serum Ischemia Modified Albumin (IMA) in preeclampsia during pre and post labour within 48 hours. A Longitudinal observational study was conducted between June 20 to April 2013in subjects with normal pregnancy (n=30), women with preeclampsia (n=30) and non-pregnant women (n=30) to evaluate the levels of IMA. The women studied were in 20-35thweeks of gestation visited obstetrics clinic in R.L. Jalappa hospital& Research center, Kolar, in a southern state of India. We estimated the maternal serum IMA levels before and after the delivery within 48 hours by using Albumin Cobalt Binding procedure. The results obtained were analysed by using Microsoft Excel 2013 and Quick R.  p value < 0.05 is considered as statistically significant. The Median IMA level in the preeclampsia group before delivery 1.071ABSU [inter quartile range (IQR) 0.453-1.708ABSU] and the same within 48hrs after delivery 1.013ABSU [inter quartile range (IQR) 0.526-1.774 ABSU)] was significantly lower (p<0.02) than in normal pregnant group before delivery 0.328 ABSU [inter quartile range (IQR) 0.154-0.592 ABSU] and the same within 48hrs after delivery 0.570ABSU [inter quartile range (IQR) 0.060-0.751 ABSU. However, a significant increase in IMA concentrations (p<0.001) when compared to non-pregnant women 0.101 ABSU [inter quartile range (IQR) 0.049-0.358ABSU]. In vivo modification of albumin at the amino terminal residues loose in vitro Cobalt (Co (II)) binding ability. The trend of Modified albumin as IMA in preeclampsia shows the gradual increase after the delivery within 48 hrs. However the levels of IMA in normal pregnancy show a tenfold increase than the non-pregnant women.

ABSTRACT

To increase the low bioavailability and short ocular residence time of lomefloxacin eye drops, aqueous solutions of drug in chitosan/ Pluronic (poloxamer) were prepared to identify suitable compositions with regard to gel forming properties and drug release behaviour. Mixtures of solutions of Pluronic (10-25% w/w) with chitosan (0.1-0.3% w/w) of different molecular weights (Mw) were prepared. Lomefloxacin release was determined using a membrane less dissolution model in artificial tear solution up to 8 hours and the samples were analyzed spectrophotometrically at 281nm. The rheological behaviour of solutions in response to dilution or temperature changes and also the phase change temperature (PCT) were determined using a brookfield’s viscometer. Antimicrobial effect of the solutions was studied in nutrient agar using Staphylococcus aureus by using agar well diffusion method. The formulation consisted of 15% Pluronic and 0.1% low Mw chitosan, with the highest release efficiency (41.952 %) , is suggested as a suitable ophthalmic preparation for sustained release of lomefloxacin HCl. It was liquid in non-physiologic conditions (pH 4 and 25ºC) and transferred to the gel form upon physiologic conditions (pH 7.4 and 37ºC). The PCT of this in situ gel did not change upon dilution.

ABSTRACT

The present study was aimed to develop generic formulation of sustained release matrix tablets of Nevirapine using TSP as a hydrophilic polymer. The tamarind seed polysaccharide was extracted from tamarind kernel powder and this polysaccharide was utilized in the formulation of matrix tablets containing Nevirapine by wet granulation technique and evaluated for its drug release characteristics. TSP is a hydrophilic and rate controlling polymer. Granules were prepared and evaluated for loose bulk density, tapped density, compressibility index and angle of repose, shows satisfactory results. Formulation was optimized on the basis of acceptable tablet properties (hardness, friability, drug content and weight variations.), in vitro drug release and stability studies. All the formulations showed compliance with pharmacopoeial standards. The in vitro release study of matrix tablets were carried out in phosphate buffer pH 7.4 for 12hr. Among all the formulations, F5 shows 99.062% better controlled release at the end of 12 hr. The results indicated that a decrease in release kinetics of the drug was observed by increasing the polymer concentration. The release data was fitted to various mathematical models such as, Higuchi, Krosmeyer-Peppas, first-order, and zero order to evaluate the kinetics and mechanism of the drug release. The drug release of optimized formulations F5 follows Krosmeyer-Peppas kinetics and the mechanism was found to be diffusion coupled with erosion (non-Fickian diffusion). The stability studies were carried out according to ICH guideline which indicates that the selected formulation were stable.

ABSTRACT

Lupus nephritis occurs about 30-40% of adult with Systemic Lupus Erythematosus and associated with increased morbidity and mortality. Focal and diffuse proliferative forms of lupus nephritis are known to progress to chronic renal failure unless treated by immunosuppressive drugs. Lupus nephritis remains a major cause of deaths among patients of Hispanic and African-American ethnicity. Generally renal involvement is more common in blacks, Indians and Chinese, with less prevalence Caucasians and Arabs. Cyclophosphamide and glucocorticoids are considered to be the standard care for the patients with proliferative lupus nephritis. Intravenous Cyclophosphamide use is limited due to its potentially severe toxic effects. Here we report a case of Cyclophosphamide induced recurrent occurrence of Urinary Tract Infection and Pancytopenia in lupus nephritis patients and it was treated by using the Mycofenolate Mofetil and Prednisolone.

ABSTRACT

Dopamine D2 and D4 receptors play an important role in cognitive functions. Acute administration of both methamphetamine and p-chloroamphetamine induced amnesia in animals but mechanisms of action remained unclear. The aim of this study was to exam both D2 and D4 receptor activation involved in methamphetamine and p-chloroamphetamine induced amnesia. Dopamine D2 and D4 receptor antagonists were challenged proceeding of acute administration of methamphetamine or p-chloroamphetamine in a passive avoidance test, an amnesia murine model. Acute administration of methamphetamine (3 mg/kg, i.p.) before the training trial induced cognition impairment in passive avoidance test. The amnesic effect could be ameliorated by pretreatment of haloperidol (a dopamine D2 receptor antagonist) and L-745,870 (a dopamine D4 antagonist). Methamphetamine also induced locomotor hyperactivity that was improved by pretreatment of haloperdiol but not by L-745,870. p-Chloroamphetamine (5 mg/kg, i.p.) also induced amnesia in passive avoidance test which was significant attenuated by haloperidol, eticlopride (a selective D2 antagonist) and L-745,870 when these antagonists were administrated 50 min before the training trial or immediately after the training trial. We proposed that both D2 and D4 receptors activation were participated in impairment of memory acquisition induced by methamphetamine and p-chloroamphetamine while dopamine D2 receptors activation was also involved in locomotor hyperactivity induced by methamphetamine.

ABSTRACT

Non-steroidal anti-inflammatory drugs (NSAIDs) whose main mechanism is inhibition of cyclooxygenases are commonly used for the management of pain. However, this mechanism is inadequate to explain the central analgesic activity of these drugs. We aimed to examine and to compare the central analgesic activity of diclofenac, etodolac, and indomethacin and the possible involvement of serotonergic and adrenergic mechanisms in their effects by using the hot plate and tail immersion tests. All drugs were assessed at same single doses (10 mg/kg). Mice were pretreated with prazosin and yohimbine, adrenergic antagonists, (1 mg/kg; i.p., 30 min. before testing) for investigating adrenergic mechanisms. Ondansetron and ketanserin, serotonergic antagonists, (0.5 mg/kg; i.p., 30 min. before testing) were also used for investigating serotonergic mechanisms. In tail immersion test, yohimbine and ketanserin decreased the antinociceptive effects of all tested NSAIDs. Ondansetron only antagonized the antinociceptive effect of diclofenac while prazosin was found ineffective. In the hot plate test, prazosin attenuated the antinociceptive effect of indomethacin and etodolac. Yohimbine, ondansetron, and ketanserin reversed the antinociceptive effects of all test drugs. The antinociception induced by tested drugs appears to be mediated either serotonergic (5-HT2/5-HT3) or adrenergic (α12) receptors in spinal/supraspinal level. 5-HT2/ 5-HT3 and α12 receptors are more associated with the supraspinal antinociceptive effect of NSAIDs while 5–HT2 and α2 receptors are predominantly involved in antinociceptive effect at the spinal level.
