An isocratic, reversed phase HPLC method was developed, using an Inertsil ODS C8 (100 x 4.6) mm,5u column and the mobile phase containing an homogenous mixture of buffer and acetonitrile (65:35,v/v). The flow rate of the mobile phase was maintained at 1.0ml/min and the detection was carried out at wavelength 250 nm. The developed method was validated with respect to linearity, accuracy (recovery), precision, system suitability, selectivity, ruggedness to prove the stability indicating ability of the...

The aim of this article was to develop pidotimod dispersible tablet and optimize the ingredients for the tablets. The effect of ingredients (diluents, disintegrants and lubricants) on the characteristics of the tablets was evaluated. The pidotimod dispersible tablets were prepared by wet granulation. The effect of diluents on the tablets was investigated by Carr’s index, dissolution, hardness, friability and taste. The effect of disintegrants on the tablets was determined by dissolution and cost. And the effect of lubricants on the tablets was studied by weight, hardness and dissolution behavior. The results showed that the optimum proportion was 400mg pidotimod, 120mg MCC, 80mg mannitol, 120mg CMS-Na, 60mg lactose, 20mg aspartame, 10mg magnesium stearate and 6%PVP 50% ethanol solution. Pidotimod dispersible tablets with optimum proportion showed acceptable taste, hardness, friability, dissolution behavior. The preparation process was simple and the tablets could be prepared by ordinary tablet production equipment. So it is suitable for mass industrialized production. The final tableting formulation and the simplified process both had tremendous potentials in commercial large-scale...

The liquisolid technique is a novel concept, where a liquid may be transformed into a free flowing, readily compressible and apparently dried powder by simple physical blending with selected carrier and coating material. The in vitro dissolution property of poorly water soluble Nifedipine was improved by exploring the potential of liquisolid technique. Different liquisolid tablets were prepared by suspending Nifedipine in PEG 400 with Avicel PH 102 as carrier, Aerosil 200 as coating material and Sodium starch glycolate as disintegrating agent. The liquid load factors for liquid vehicle was calculated to obtain the optimum amounts of carrier and coating materials necessary to produce acceptable flowing and compactable powder admixtures viable to produce tablets. The formulated liquisolid tablets were evaluated for post compression parameters such as weight variation, hardness, friability and drug content uniformity. The interaction between drug and excipients in prepared Liquisolid tablets were studied by differential scanning calorimetry (DSC) and FT-IR. The result showed that liquisolid formulation of Nifedipine exhibited higher percentage of drug release than directly compressed...

The genus Swietenia belongs to Meliaceae family which consists of 37 genera and about 300 species which is found in most of the parts of India. In present investigation we made an efficient effort to extract ricinoleic acid from the seed oil of Swietenia humilis, Zucc. They are used in medicine folklore to cure various diseases in Mexico, Africa and India. Physicochemical properties of Swietenia humilis Zucc seed oil were identified along with its fatty acid composition. The structure of the ricinoleic acid was confirmed by IR, NMR and Mass spectral studies. The extracted ricinoleic acid was screened for its antimicrobial and anthelmintic...

Energy drinks (EDs) are caffeine-based beverages that commonly contains large amount of carbohydrates, sugar, health supplements and various energy stimulants, such as ginseng and vitamin B, to name a few. These drinks are marketed for young people actively involved in sports or overworking hours, as natural alternatives that increases fun and improve physical and cognitive performances such as attention, concentration and alertness. There are commonly held false perceptions that the consumption of EDs can rectify the impairment to human physiology because of alcohol consumption including visual reaction time and motor coordination, which is highly required for sports and driving activities, to name a few. The sensory analysis was done in the form of survey. The statistical analysis was done using SPSS software and Analysis of Variance (ANOVA). The graph was obtained between feedbacks (given by the candidates) and number of people for different sensory properties like smell, taste, flavour, texture, and...
