Flurbiprofen is a water insoluble non-steroidal anti inflammatory drug and belongs to BCS Class II categories. Solid dispersion is a technique by which we can improve it water solubility. By the help of fast dissolving formulation we can evaluate the effectiveness of solid dispersion. In this research work the solid dispersion of flurbiprofen with polymer like PVP K25, PVP K30, PVP K29-32, and ...

The enhancement of oral bioavailability of poorly water-soluble drugs remains one of the most challenging aspects of drug development. Tadalafil a BCS class II drug is an impotence agent. It is indicated for the treatment of erectile dysfunction and is a selective inhibitor of cyclic guanosine monophosphate (cGMP)-specific phosphodiesterase type-5 (PDE-5).However, insolubility and poor dissolut...

the present study deals with characterization of dispersions of a poorly water-soluble drug, celecoxib (clx) in polyvinyl caprolactame–polyvinyl acetate–polyethylene glycol graft copolymer (soluplus® (sol)) prepared by different techniques. dispersions of clx in sol at different ratios (2:1, 1:1, 1:2, 1:4 and 1:6) were prepared by spray drying, conventional solvent evaporation and melting metho...

Objective(s):Solid dispersion formulation is the most promising strategy to improve oral bioavailability of poorly water soluble drugs. The aim of this study was to compare the effect of polyvinylpyrrolidone K30 (PVP) and poloxamer-188 (PLX) as carrier in solid dispersion formulations of celecoxib (CLX). Materials and Methods: Solid dispersions of CLX:PVP or CLX:PLX were prepared at different r...

Paracetamol is an important anti-inflammatory and analgesic drug widely used in biological disorders. One of major problems with this drugs is its low solubility thus dissolution rate in biological fluid, which results into poor bioavailability after oral administration. In this study polyvinyl pyrrolidone (PVP) is used to enhance bioavailability of paracetamol. Paracetamol and PVP are used in ...

Efavirenz is an HIV-1 specific, non-nucleoside reverse transcriptase inhibitor (NNRTI).It is an antiretroviral agent indicated for the treatment of human immunodeficiency virus type 1 (HIV-1) infection, which is not soluble in water and lower absorption in gastric fluid. In order to improve the solubility and oral absorption of the drug in gastric fluid and to enhance its dissolution rate, soli...

objective(s) the purpose of the present study was to use the solid dispersion (sd) technique to improve the dissolution rates of indomethacin (imc). materials and methods imc solid dispersions in pvp k30 and isomalt (galen iq 990) were prepared using the solvent evaporation technique and a hot melt method in weight ratios of 2, 10 and 30% (imc:pvp). solid dispersions and physical mixtures were ...

Etoricoxib, a non-steroidal anti-inflammatory drug, is used to Osteoarthritis, Rheumatoid arthritis and Acute Gouty arthritis. Etoricoxib is practically insoluble in water; hence present study was carried out to enhance dissolution properties of Etoricoxib through the preparation of Solid Dispersions using PEG 6000 as carrier at various proportions by using different techniques like Physical mi...

The main objective of the current study was to formulate poorly water soluble drug Spirinolactone by using solid dispersion technique in order to achieve a better dissolution rate which would further help in enhancing oral bioavailability. Solid dispersions were prepared using two methods; solvent method and fusion method. Solid dispersion was prepared by using polymers, such as Hydroxy propyly...

Solid dispersions traditionally have been used as effective methods to improve the dissolution properties and bioavailability of poorly water-soluble drugs. Furosemide a loop diuretic belonging to Biopharmaceutical Classification System (BCS) Class IV, has very poor water solubility. The aim of the present study was to improve the solubility and dissolution rate of a poorly water-soluble drug, ...
