Nanoemulsions are submicron sized emulsions that are under investigation as drug carriers for improving the delivery of therapeutic agents. These are the thermodynamically stable isotropic system in which two immiscible liquids are mixed to form a single phase by means of appropriate surfactant and cosurfactant. Nanoemulsion droplet sizes fall typically in the range of 20-200nm and shows narrow si...
The poor dissolution rate of water-insoluble drugs is still a major problem conforming the pharmaceutical industry. The most common method for improving the solubility is by increasing the surface area of the drug through micronization. But, in practice the effect of micronization is often disappointing, especially when the drugs are encapsulated or tablet. It is generally recognized that low solu...
Chromolaena odorata or siam weed is regarded as one of the most harmful weeds present on earth. Many efforts are being made for the control of this weed. But, none of them have provided any significant success. It has been utilized in the traditional medicinal systems for its curative properties for centuries. Some of the current studies have revealed its medicinal properties which have lead to an...
The stems of Cissus quadrangularis L. (Vitaceae) are reported to have great medicinal value. The present investigation was therefore undertaken to determine the requisite pharmacognostic standards for evaluating the plant material. The macroscopic features of the Cissus quadrangularis L. stem were observed under magnifying lens. Microscopic characters and powder analysis were determined under micr...
Oral drug delivery remains the preferred route of drug delivery. Novel technologies with improved performance, patient compliance, and enhanced quality have emerged in the recent past. The fast dissolving drug delivery system started gaining popularity and acceptance as a new drug delivery system because they are easy to administer and lead to better patient compliance. Fast dissolving drug delive...
DEVELOPMENT AND VALIDATION OF SPECTROPHOTOMETRIC METHOD FOR SIMULTANEOUS ESTIMATION OF GLICLAZIDE AND METFORMIN HYDROCHLORIDE IN BULK AND TABLET DOSAGE FORM BY SIMULTANEOUS EQUATION METHOD
A simple, rapid, accurate, precise, specific and economical spectrophotometric method for simultaneous estimation of Gliclazide (GLC) and Metformin hydrochloride (MET) in combined tablet dosage form has been developed. It employs formation and solving of simultaneous equation using two wavelengths 227.0 nm and 237.5 nm. This method obeys Beer’s law in the employed concentration ranges of 5-25 μ...
Oral Disintegrating Drug Delivery Systems (ODDDS) have the unique property of rapidly disintegrating and/or dissolving and releasing the drug as soon as they come in contact with saliva, thus obviating the requirement of water during administration. Methods to improve patient’s compliance have always attracted scientists towards the development of fancy oral drug delivery systems. Among them, or...
ANTIOXIDANT, ORGAN PROTECTIVE AND AMELIORATIVE PROPERTIES OF METHANOL EXTRACT OF ANOGEISSUS LEIOCARPUS STEM BARK AGAINST CARBON TETRACHLORIDE- INDUCED LIVER INJURY
The methanol extract of the stem bark of Anogeissus leiocarpus was evaluated in vivo at 2.5mg/kg for antioxidant, hepatoprotective and ameliorative effect on hepatocellular injury following pre-treatment or post-treatment with carbon tetrachloride (CCl4). Levels of the lipid peroxidation product, malondialdehyde (MDA) or thiobarbituric reactive substances (TBARS) were taken as a measure of oxidati...
The synthesis of gold nanoparticles has received considerable attention and has been a focus of research due to their high chemical and thermal stability, fascinating optical, electronic properties, and promising applications such as nanoelectronics, biomedicine, sensing, and catalysis. Different physical and chemical methods for gold nanoparticles synthesis are known but these methods are either ...
ANTIBACTERIAL, RADICAL- SCAVENGING ACTIVITIES AND CYTOTOXICITY PROPERTIES OF PHALERIA MACROCARPA (SCHEFF.) BOERL. LEAVES IN HEPG2 CELL LINES
Antibacterial, and radical scavenging activities of four crude extracts of Phaleria macrocarpa (Scheff) Boerl.) leaves extracts and its active crude cytotoxic properties in HepG2 cells were investigated. The susceptibility bacteria tests were performed by the Mueller Hinton agar well diffusion method. The Radical scavenging activity was measured by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method...
