Aim of the present investigation was to develop cellulosic polymer based mucoadhesive antifungal gel comprising novel ternary mixture of miconazole nitrate (MN) for buccal delivery. Crosslinking of gel was made by adjusting pH with triethanolamine (TEA) and gel formulation was optimized on the basis of flux of MN (0.562-1.751 mg/cm(2)/h) calculated from ex(More)
In search of the effective and standardized hepatoprotective combination therapy, silymarin and standardized extract of Phyllanthus amarus has been evaluated against CCl(4)-induced hepatotoxicity in rats. Eight groups of rats were used. The animals of group A served as normal and were given only vehicle. The animals of group B served as toxin control and(More)
Isoliquiritigenin (ISL), a chalcone and liquiritigenin (LTG), a flavonoid found in licorice roots and several other plants. ISL displays antioxidant, anti-inflammatory, antitumor and hepatoprotective activities whereas LTG is an estrogenic compound, acts as an agonist selective for the β-subtype of the oestrogen receptor. Both the phenolics were isolated(More)
In North India, poultice of young unfolded leaves of Argyreia speciosa Linn. (Convolvulaceae) is used for healing wounds. In order to find scientific evidence for the traditional utilization of leaves of A. speciosa in wound healing, this investigation was carried out. A linear incision wound of about 3 cm in length and 2 mm in depth and circular excision(More)
Liver is a vital organ responsible for plethora of functions including detoxification, protein synthesis, and the production of biochemicals necessary for the sustenance of life. Therefore, patients with chronic liver diseases such as viral hepatitis, liver cirrhosis, and hepatocellular carcinoma need immediate attention to sustain life and as a result are(More)
Mentha spicata L. var. viridis oil (MVO) is a potent antifungal agent, but its application in the topical treatment is limited due to its irritancy and volatility. It was aimed to develop more efficient, chitosan-incrusted MVO microspheres with reduced volatility and lesser irritancy and to dispense it in the form of ointment. Simple coacervation technique(More)
CONTEXT Enhancement of aqueous solubility of very slightly soluble Miconazole Nitrate (MN) is required to widen its application from topical formulation to oral/mucoadhesive formulations. OBJECTIVE Aim of the present investigation was to enhance the aqueous solubility of MN using binary and ternary mixture approach. MATERIALS AND METHODS Binary mixtures(More)
The aim of the present work was to develop and characterize mucoadhesive film of cellulose (methyl cellulose and hydroxy propyl methyl cellulose) and polymethacrylate (Eudragit RSPO) polymers for buccal delivery of carvedilol. Drug and polymers were found to be compatible as revealed by FTIR and DSC analysis. Mucoadhesive films were prepared by solvent(More)
The present work was aimed to develop an antiseptic cream formulation of Indian basil oil utilizing hydrophilic-lipophilic balance approach. In order to determine the required-hydrophilic lipophilic balance (rHLB) of basil oil, emulsions of basil oil were prepared by phase inversion temperature technique using water, Tween 80, and Span 80. Formulated(More)
Andrographolide (AP), a phytoconstituent of Andrographis paniculata is reported as a potent hepatoprotective agent. However, utility of this molecule is restricted due to its low aqueous solubility, gastric instability and hence low bioavailability. It was aimed to formulate and characterize AP-loaded, natural biopolymer stabilized, multilayered(More)
