The present study focuses on the synthesis of ZnO nanoparticles by chemical method in alcohol base using three different capping agents-Thioglycerol, oleic acid and Triethanol amine (TEA). The effect of concentrations was analyzed for their effectiveness in particle growth and antibacterial activity. The antibacterial activity of ZnO nanoparticles using these capping agents at different concentrations was tested against six laboratory microorganisms namely Escherichia coli, Bacillus subtilis, Pseudomonas aeruginosa, Staphylococcus aureus, Proteus, and Klebsiella by agar well diffusion method. Zone of inhibitions produced by ZnO nanoparticles with different capping agents was tabulated. The quantitative measurement of zones of inhibition led to the conclusion that all the capping agents were effective in inhibiting growth of different organisms of which the maximum activity was shown by Thioglycerol, capped ZnO nanoparticles at a concentration of 0.12% against all...

The work was aimed to develop an immediate release tablet formulation of Fenofibrate and Rosuvastatin in combination for better treatment as well as management of hypercholesterolemia and prevention of cardiovascular diseases. The target was also set to improve the dissolution profile of poorly soluble Fenofibrate. For manufacturing these immediate release combined formulation tablets, Hot-Melt Technology was used which helped in enhancing dissolution profile and moreover, here amino acids are used in conjunction with other excipients. In the developed formulation, the amino acids imparted its action as excipient by helping in the solubilization process which facilitated the release rate of Fenofibrate. The formulated tables were then investigated for hardness test, friability test, weight uniformity and dissolution test. The results showed that all tablets met the expected requirements for these tests and the release rate of fenofibrate also got improved giving an excellent dissolution profile for both fenofibrate and...

The Zingiberaceae has the great importance in the plant kingdom because the members of this family give up spices, perfumes, dyes and valuable medicines. Alongside, a number of species of this family are cultivated for flowering. Mango ginger is one of the important species of this family having medicinal and biological properties such as antiageing, antibacterial, antioxidant, anti-inflammatory, antiallergic, antifungal, platelet aggregation inhibition activity and analgesic activity. In Ayurveda and Unani medicines of system, its rhizomes are useful as expectorant, appetizer, alexteric and laxtative. The rhizomes of mango ginger are also used in skin diseases, bronchitis, asthama and inflammatiom. Present examination aims to evaluate and compare antioxidant potential of different extracts of mango ginger using 1,1-diphenyl-2-picrylhydrazyl assay. In this study, methanol and ethyl acetate extracts of mango ginger rhizomes was estimated as good antioxidant activity which is may be due to phenolics, curcuminoids, essential oil, terpinoids and flavonids present in good amounts in these extracts, whereas dichloromethane and aqueous extracts has very little capability of radical scavenging...

The present study depicts formulation and characterization of boric acid gel formulations. The formulated gels intervenes the advantages of gels along with higher and effective antimicrobial activity when compared to the formulations available in the market. The preparations were evaluated for different parameters as basic physico-chemical properties like physical appearance, texture, pH measurement, spreadability, viscosity and spectral analysis (UV-Visible and IR Spectroscopy) for its standardization. The sharp peak at 230nm was obtained in UV-Vis spectra. I.R spectra revealed that the boric acid binds extensively to the polymers. Antimicrobial activity of formulation was studied using Muller Hinton agar medium against E.coli MTCC 614 and S.aureus MTCC...

Objective: The objective of the present investigation was to formulate and evaluate hydrodynamically balanced floating matrix controlled drug delivery system of Zolmitriptan by increasing its residence time and improves the bioavailability. Methods: Twelve different formulations of floating tablets were prepared using direct compression technique with hydrophilic polymers such as HPMC K4M, K15M, K100M and hydrophobic polymer like ethyl cellulose in different ratios. Dry powder blends of all the formulations were evaluated for precompression parameters and all the formulations were evaluated for post compression parameters after compression into tablet. Characterization of the prepared formulation was done by FTIR and DSC analysis. In-vitro dissolution studies were carried out for all the formulations and optimised formulation was analysed for kinetic as well as mechanism of drug release. Accelerated stability studies were carried out for the optimised formulation at stressed temperatures/humidity conditions i.e 40 ± 2 °C/70 ± 5% RH. Results: The evaluation results of precompression and postcompression parameters revealed that all formulations comply with the specification of official pharmacopoeias. From DSC and...
