objective(s): the aim of this work was to investigate the effect of the natural and the chemically modified form of cyclodextrins namely; β-cyclodextrin (β-cd) and hydroxypropyl-β-cyclodextrin (hp-β-cd) respectively on the solubility and dissolution rate of aripiprazole; an antipsychotic medication showing poor aqueous solubility.   materials and methods: phase solubility of aripiprazole with t...

the present investigation was focused to formulate semi-solid capsules (sscs) of hydrophobic drug telmisartan (tlms) by encapsulating semi-solid matrix of its solid dispersion (sd) in hpmc capsules. the combinational approach was used to reduce the lag time in drug release and improvise its dissolution. sds of tlms was prepared using hot fusion method by varying the combinations of pluronic-f68...

− Fenofibrate has been used for many years to lower cholesterol levels and its pharmacokinetic profile is well understood. However, due to its low solubility in water, it has low bioavailability after oral administration. In order to improve the dissolution rate, fenofibrate was formulated into a self-microemulsifying drug delivery systems (SMEDDS). We used pseudo-ternary phase diagrams to eval...

the present work was aimed to design and develop self-nanoemulsifying drug delivery systems (snedds) with the objective to overcome the problems associated with the delivery of talinolol, a hydrophobic and poorly bioavailable drugs having ph dependant solubility. the solubility of talinolol in various oils, surfactants, cosurfactants and aqueous phases were determined to identify and select the...

A combination of fusion and surface adsorption techniques was used to enhance the dissolution rate of cefuroxime axetil. Solid dispersions of cefuroxime axetil were prepared by two methods, namely fusion method using poloxamer 188 alone and combination of poloxamer 188 and Neusilin US2 by fusion and surface adsorption method. Solid dispersions were evaluated for solubility, phase solubility, fl...

diosmin, a vascular-protecting agent, is practically insoluble in water, and its oral absorption is limited by its extremely low dissolution rate. in this study, β-cyclodextrin (βcd) and 2-hydroxypropyl-β-cyclodextrin (hpβcd) were obtained to improve the solubility and dissolution rate of diosmin. phase solubility studies of diosmin with βcd and hpβcd in distilled water were conducted to charac...

Pioglitazone, a class II Biopharmaceutical Classification System drug having poor water solubility and slow dissolution rate may have a negative impact on its subtherapeutic plasma drug levels leading to therapeutic failure. In order to improve its water solubility and thus dissolution, cyclodextrin complexation technique was followed. The phase solubility studies were carried using three diffe...
