Objective: A new, simple, sensitive, and economical UV spectro-photometric method was developed for the simultaneous analysis of Adapalene and Dapsone in pharmaceutical formulation. Method: This UV method was developed with Tetrahydrofuran and Distilled water as solvents. The wavelengths selected for analysis in the present method were 237 nm and 293 nm. The method was validated as per ICH guidelines. Results: The method was validated for linearity, accuracy, precision, specificity and robustness. Linearity was found to be within the concentration range of 0.05-0.25 µg/ml for Adapalene and 2.5-12.5 µg/ml for Dapsone. Accuracy for the method was determined by recovery studies. The % drug recovered was found to be 99-102% w/w. The % RSD values of repeatability and intermediate precision were found to be less than 2, providing method was precise in nature. From all these studies it was observed that there was no interference of excipients from the formulation during the analysis. Conclusion: The advantages of this method for analytical purposes lie in the rapid determination, its cost-effectiveness, easy preparation...

Background: Leukocytes play an important role in tissue apoptosis as scavengers and vital components of inflammation, which has been generated during ischemia-reperfusion injury. The present study aimed to investigate the cerebroprotective potential of naringin through anti-inflammatory mechanism. Methods: Cerebral infarction was induced through bi-lateral common carotid artery occlusion for 30 min and 4 h reperfusion in rats. Cerebral infarction, number of leukocytes/cu.mm, and inflammatory markers (TNF α, IL-6 and IL-10) were measured in ischemic rat brain. Results: Percentage of infarction, the number of leukocytes/cu.mm, inflammatory markers (TNF-α, IL-6) and myeloperoxidase were significantly increased, and IL-10 levels were significantly decreased in ischemia-reperfusion injury rats relative to sham control rats. Percentage of infarction, the number of leukocytes/cu.mm, inflammatory markers TNF-α, IL-6, and myeloperoxidase were significantly decreased and IL-10 levels were significantly increased in naringin treated rats relative to ischemia-reperfusion injured rats. Conclusion: This study indicates that infiltrating leukocytes and inflammation plays a key role in cerebral ischemia- reperfusion injury and naringin alleviate the inflammation and infiltrating...

The study aims to investigate the antioxidant and antidiabetic activity of Leucaena leucocephala ethanol leaf extract (LLME). L. leucocephala leaves extraction was carried out by the maceration method. Phytochemical analysis was performed using standard analytical procedures. Diphenyl picrylhydrazyl (DPPH) radical and 2, 2’-azinobis (3-ethylbenzathiazoline-6-sulfonic acid) (ABTS) radical scavenging assay; α-amylase and α-glucosidase inhibition assays were performed. The extraction yield of LLME by maceration was 65%. The phytochemical screening confirmed the presence of alkaloids, monosaccharides, proteins, amino acids, steroids, flavonoids, glycosides, tannins, and saponins. The total phenol content of LLME was 970 mg of GAE/g, and total flavonoid content was found to be 550 mg of QE/g. In DPPH and ABTS assay LLME showed good antioxidant activity (IC50: 11.21 ± 0.2 and 11.87 ± 0.05 µg/mL) when compared to the standard drug, ascorbic acid (IC50:11.09 ± 0.05 and 11.01 ± 0.09 µg/mL). Similarly, in α-amylase and α-glucosidase inhibition assay, acarbose revealed enzyme inhibition activity with an IC50 value of 12.02 ± 0.02 and 12.11 ± 0.02 µg/mL while LLME showed...

The objective of the present study was to develop and characterize the fast disintegrating tablets, which rapidly disintegrates in the sublingual area without the need of water or with a little amount of water. Amlodipine besylate is a calcium channel blocker (long-acting) basically used in the treatment of angina and hypertension for immediate relief in life-threatening conditions. In this work, we prepared the fast disintegrating tablet of Amlodipine besylate for the increasing rate of dissolution using two different classes of super-disintegrating agents naturals are (Locust bean gum; Plantago ovata) and synthetic are (Croscarmellose sodium, Crospovidone). The method of preparation was direct compression. The pre-formulation studies were also performed. The tablets were prepared and evaluated according to the parameters in the pharmacopeia. Results revealed that fast disintegrating tablets prepared with Locust bean have the highest drug release (in-vitro) of 98% within 30 min. The use of Locust bean as super disintegrant has majorly promoted the rapid release of the active drug. This study gives knowledge about the pivotal fundaments related...

Chemoprevention is the novel approach that inhibits and delays or reverses the process of cancer development by using natural herbs and plant products. The aim of the present study was to evaluate the anticancer efficacy of orally administered Capparis decidua fruit extract (CDE) on skin carcinogenesis model in swiss albino mice by the single topical application of the 7,12 dimethylbenz (a)anthracene (100µg/100µl of acetone) followed by croton oil after 2 weeks (1% in acetone/thrice in a week). Oral administration of the CDE at a dose of 50 mg/kg b.wt./day during the peri initiation stage (one week before DMBA and one week after the application followed by croton oil till the end of the experiment) and post-initiation stage (after 2 weeks DMBA application, from the day of croton oil treatment till the end of the experiment). A significant reduction in the tumor incidence, tumor burden, and a cumulative number of papillomas was observed, along with the increase in the average latent period in mice treated with CDE drugs compared with...
