Pioglitazone is an anti-diabetic drug in high blood sugar in patients with type 2 diabetes (non-insulin-dependent diabetes) which was belongs to poor aqueous solubility and bioavailable drug. By using β Cyclodextrin, the solubility and dissolution rate of Pioglitazone HCL can be enhanced and it was evaluated by synthesizing it into solid inclusion complexes in different ratio of drug: β cyclode...

Atorvastatin is a BCS class II lipid lowering agent. It is insoluble in aqueous solution of pH 4 and below; it is very slightly soluble in water and pH 7.4 phosphate buffer. In the present investigation an attempt has been made to enhance solubility and dissolution of poorly soluble drug by formulating self microemulsifying drug delivery system (SMEDDS). The solubility of atorvastatin in indivi...

  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 ar...

Fexofenadine is a selective histamine H(1) receptor antagonist, used for relief of the symptoms of allergy. However its aqueous solubility is very poor. Solid inclusion complexes of fexofenadine and β-cyclodextrin were prepared at the molar ratios of 1:1 and 1:2 by kneading, and coprecipitation methods to improve its solubility. Characterization of the complexes was performed using infrared spe...

In vitro dissolution methodologies that adequately capture the oral bioperformance of solid dosage forms are critical tools needed to aid formulation development. Such methodologies must encompass important physiological parameters and be designed with drug properties in mind. Two-phase dissolution apparatuses, which contain an aqueous phase in which the drug dissolves (representing the dissolu...

The aim of this study was to design orally disintegrating tablets of Olanzapine and to complex Olanzapine with 2-hydroxypropyl-β- cyclodextrin with special emphasis on disintegration and dissolution studies. Phase solubility studies demonstrated the formation of 1:1 molar inclusion complex by kneading method. Tablets were prepared by using superdisintegrants namely, sodium starch glycolate, cro...

Ciprofloxacin bioavailability may be reduced when ciprofloxacin is co-administered with metallic ion containing preparations. In our previous study, physicochemical interaction between ciprofloxacin and ferrous sulphate was successfully simulated in vitro. In the present work, comparative in vitro ciprofloxacin solubility and dissolution studies were performed in the reactive media containing a...

piroxicam (px), an anti-inflammatory drug, exhibits poor water solubility, dissolution and flow properties. thus, the aim of the present study was to improve the solubility and dissolution rate of px by freeze drying technique using dimethylformamide (dmf), chloroform and water as co-solvent system. the prepared crystals containing px were evaluated for dmf and chloroform solvent residual by ga...

Several attempts have been made to improve the solubility of water insoluble drugs. Over the years, inclusion complexation of drugs with β-cyclodextrin has emerged as a viable attempt to improve the dissolution of water insoluble drugs. The aim of the present work was to improve the dissolution rate of lovastatin, a water insoluble drug, by inclusion complexation with β-cyclodextrin. The stoich...
