Antispasmodic activity of the ethanolic extracts of different parts of Nyctanthes arbortristis Linn. was estimated using guinea pig ileum preparation against acetylcholine. Anthelmintic activity was tested following the method described by Kailashraj and Kurup, using earthworm (Pheretima posthuma). The extracts exhibited antispasmodic activity, which was less than that of piperazine citrate. The e...
FORMULATION OF MEDICATED CHEWING GUM OF ONDANSETRON HYDROCHLORIDE AND ITS PHARMACOKINETIC EVALUATIONS
An attempt has been made to formulate new chewing gum device for ondansetron hydrochloride in the form of tablet. The new drug delivery system was obtained, at room temperature, by direct compression using conventional pharmaceutical equipment. The resulting chewing gum tablets comprise a gum core combined with fillers, antioxidants, coloring agent and plasticizers, which provide smooth appearance...
The purpose of the current work was to conduct phytochemical screening and antioxidant activity of different extracts of Leucas aspera. The dried powder of the whole plant was extracted with n-hexane, ethyl acetate and ethanol which were subjected to various chemical tests to ascertain the main constituents of the plant. The results revealed the presence of significant amounts of alkaloids, glycos...
Recently much attention has been paid to the application of microemulsion as drug delivery system. Part of this interest appears as a consequence of their transparency, ease of preparation and long-term stability. These properties as well as their ability for incorporating drugs of different lipophilicity are some of the reasons why microemulsions have been thoroughly considered for pharmaceutical...
Solid lipid nanoparticle proved appropriate as prolonged release formulation for lipophilic drugs. The present work dealt with the preparation of the antifungal lipophilic drug nystatin into solid lipid nanoparticles ((Nyst-SLNs).) formulation for topical delivery with the aim to prolong its release and effectiveness. Hot homogenization and ultrasonication were applied in the production of (Nyst-S...
The present research work was aimed at the enhancement of solubility of Candesartan by Self Emulsifying Drug Delivery Systems (SEDDS). Candesartan is a BCS class II drug having low aqueous solubility and high permeability; hence its bioavailability is solubility rate limited. The saturated solubility of Candesartan in various oils and surfactants was determined. The excipients were screened and se...
ANTIDIABETIC AND GLYCOGENESIS EFFECTS OF DIFFERENT FRACTIONS OF METHANOLIC EXTRACT OF MOMORDICA CHARANTIA (LINN.) IN ALLOXAN INDUCED DIABETIC RATS
The study was undertaken to investigate the antihyperglycemic, oral glucose tolerance test (OGTT) and glycogenesis effects of the different fractions (Petroleum ether, ethyl acetate and chloroform) of methanolic extract of Momordica charantia. The different fractions of the extract were administered intraperitoneally as a single dose of 150 mg/kg body weight to alloxan induced as well as glucose i...
The practice of traditional medicine for the control of fertility in most parts of India is based on the uses of plant medicines for many years. The fact that herbal medicines have been employed for such a long time does not guarantee their efficacy and safety. The aim of the present study was, therefore, to carry out phytochemical screening, efficacy and safety studies on one of the traditionally...
RP-HPLC METHOD DEVELOPMENT AND VALIDATION FOR SIMULTANEOUS ESTIMATION OF RANITIDINE HYDROCHLORIDE AND DOMPERIDONE IN COMBINED TABLET DOSAGE FORM
A simple reverse phase HPLC method was developed for the simultaneous estimation of Ranitidine hydrochloride and Domperidone present in combined tablet dosage forms. Efficient chromatographic separation was achieved on Phenomenax C18 stationary phase (250 X 4.6 mm i. d., 5μ particle size) with simple mobile phase combination of phosphate buffer: acetonitrile: methanol 40: 30: 30 (V/V/V) in an iso...
Let G=(V,E) be a simple connected molecular graph in chemical graph theory, where the vertex set and edge set of G denoted by V(G) and E(G) respectively and its vertices correspond to the atoms and the edges correspond to the bonds. A topological index of a graph G is a numeric quantity related to G which is invariant under automorphisms of G. In this paper, the vertex Szeged index of Titania carb...
