DESIGN AND EVALUATION OF DILTIAZEM HYDROCHLORIDE LOADED BUCCAL PATCH
The purpose of this study was to develop and optimise the formulation of mucoadhesive patches of Diltiazem hydrochloride using chitosan as base matrix. The patches were prepared by solvent casting method. PVP (K30) and propylene glycol were introduced into the patches formulae to improve the filming properties. The patches were found to be smooth in appearance, uniform in thickness, weight, and ...

DESIGN AND CHARACTERIZATION OF PULSATILE DRUG DELIVERY SYSTEM OF LERCANIDIPINE
The purpose of the present investigation is to formulate and evaluate Lercanidipine pulsatile drug delivery system by press coating method. The inner core tablets were prepared by using direct compression method by using cross-carmellose sodium (Ac-Di-Sol), sodium starch glycolate, crospovidone as super disintegrants. The drug polymer interaction was investigated by FTIR and their results directed...

DEVELOPMENT AND VALIDATION OF STABILITY – INDICATING RP-HPLC CHROMATOGRAPHIC METHOD BY FORCED DEGRADATION STUDIES FOR AZATHIOPRINE BY RELATED SUBSTANCES
Simple, rapid and reproducible stability-indicating methods were established for quantitative determination of azathioprine using a, phenomenex 250 mm × 4.9 mm C18, 5 µm, inertsil and UV detection at 240 nm. The isocratic elution was used to quantify the analyte and the mobile phase was acetate buffer: acetonitrile: methanol (30: 35: 35) was pumped at 1.0 mL/min. The method was linear between 10...

ESTIMATION OF QUERCETIN CONTENT IN THREE DIFFERENT SPECIES OF EUPATORIUM BY HIGH-PERFORMANCE THIN-LAYER CHROMATOGRAPHY
Three different species of Eupatorium namely E. glandulosum, E. odoratum and E. triplinerve belongs to the family Asteraceae are selected for the analysis of quercetin content. Leaves are extracted with ethanol and water and used for the analysis of quercetin by HPTLC technique using the mobile phase containing toluene: ethyl acetate: formic acid: methanol (5.5:4:1:0.5). Determination of quercetin...

SYNTHESIS, EXPERIMENTAL STUDIES OF THE ANTIMICROBIAL POTENTIAL OF SOME NOVEL 1, 5- BENZO THIAZEPINE DERIVATIVES
Optically active 1, 5- benzothiazepines belong to the well known benzothiazepine type substances. Some of them possess important bioactivities. In this article, optically active 2, 3-dihydro-1, 5-benzothiazepine derivatives are synthesized by the reaction of new α-β unsaturated carbonyl compounds with 2-aminothiophenol under mild conditions in the presence of silver sulphate in acetonitrile in s...

PELLETIZATION OF LAMOTRIGINE SOLID DISPERSION FOR IMPROVED SOLUBILIZATION
Poorly solubility in water of many newly developed high-potential drugs is an obstacle in formulation development. The aim of this study was to increase the solubility of Lamotrigine which is a poorly soluble drug and comes under BCS class-II by using solid dispersion technique. Lamotrigine, PEG 4000 and PVPK-30 solid dispersion was prepared by solvent evaporation method and the formulation was ch...

DEVELOPMENT AND CHRACTERIZATION OF SELF ASSEMBELED NANOPARTICLES: A REVIEW
Various types of lipid based vesicular systems have been developed in controlled and targeted drug delivery. Self assembled nanoparticles (SAN) has advantages over traditional colloidal vesicular systems and also avoids some of their major disadvantages. SAN made of solid lipids are submicron colloidal carriers (50-1000nm). These consist of a solid hydrophobic core having a monolayer of phospholip...

CYTOTOXIC ACTIVITY OF CROCUS PALLASII SUBSP. HAUSSKNECHTII IN HUMAN CANCER CELL LINES
Crocus pallasii subsp. haussknechtii grows in the west of Iran where local people consume the corm. It belongs to a saffron family (Iridaceae), which has shown several biological activities including cytotoxic and anti-angiogenesis properties. The corm (the nut and the surrounding fibers) and aerial parts of the species have shown anti-angiogenesis properties in HUV-EC-C cells previously; in the p...

TO INVESTIGATE THE EFFECT OF SPAN 60 AND SPAN 80 POLYMER ON RELEASE RATE OF SIMVASTATIN NOISOME IN COMPARISON WITH PURE SIMVASTATIN
The main objective of the present study was to develop and evaluate the simvastatin noisome using different grades of nonionic surfactants. It was hypothesized that niosomes would increase in vitro release of simvastatin in comparison to the API Mumbai. Niosome were prepared by thin-film hydration method and evaluated for particle size, entrapment efficiency, PDI, and in vitro release. The differe...
