The main objective of this study was to prepare Risperidone (RIS) nasal powder by spray drying method, so as achieve controlled drug release and high deposition efficiency in the cavity. microparticles with uniform size controllable structure were prepared mixing hydroxypropyl -βcyclodextrin (CD) API before a novel microfluidic technology. properties particles characterized terms particle size,...

The purpose of the present study is to prepare different combinations of drug Simvastatin (SV) with different polymers like Sodium alginate (SA), Hydroxypropylmethylcellulose (HPMC), Pectin (P), Dillenia (D) and Hydroxy propyl βcyclodextrin. (HPC), thereby determine and report any possible interactions between the drug Simvastatin (SV) and various polymers both from natural and synthetic source...

Article history: Received on: 11/01/2013 Revised on: 29/01/2013 Accepted on: 15/01/2013 Available online: 30/03/2013 The drug 5 fluorouracil is sparingly soluble in water. The aqueous solubility and dissolution rate of 5-fluorouracil can be increased by inclusion complexation with β-cyclodextrin. Molecular-modeling studies support the formation of stable molecular inclusion complexation of 5-fl...

Purpose: To formulate simvastatin orodispersible tablets with high dissolution rate and enhanced bioavailability. Methods: Simvastatin solid dispersions in βcyclodextrin, hydroxylpropyl-β-cyclodextrin, and hydroxylbutyl-β-cyclodextrin were prepared in different drug: polymer ratios by kneading and solvent evaporation methods. Compatibility was investigated by Differential scanning calorimetry (...

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...

The enhancement of oral bioavailability of poorly water soluble drugs remains one of the most challenging aspects. Utilization of cyclodextrins attracted the attention of many researchers for the enhancement of the dissolution rate. The complexation of diltiazem hydrochloride with βcyclodextrin (CD) was investigated by phase solubility. Phase solubility study was performed to determine stiochio...

Objectives: The objective of this endeavour is to prepare βcyclodextrin (β-CD) inclusion complex with sulfonamide (SAP) using the co-evaporation technique and screened its effect on in-vitro antimicrobial property against some Gram-positive and Gramnegative bacteria. Methods: A new sulfonamide SAP (4-amino-N-(1, 5-dimethyl-3oxo-2-phenyl-2, 3-dihydro-1H-pyrazol-4-yl) benzene sulfonamide) 4 has b...

Domperidone Maleate (DOM), an antiemetic drug, has been used in treatment of adults and children. It has low aqueous solubility and hence low bioavailability. In present study, an attempt has been made to enhance the solubility of DOM by inclusion complexation with Hydroxypropyl-βCyclodextrin (HP-β-CD) using kneading technique and formulation of fast disintegrating tablets by using Sodium Starc...

The synthesis of the β-cyclodextrin-5-flucytosine inclusion complex in aqueous media has been recently reported, the characterization of the complex proving the complete inclusion of the 5-flucytosine molecule into the β-cyclodextrin cavity. Still, the type of interactions that stabilize the supramolecule and the structure of the complex have been poorly described. The present paper focuses on ...
