Gelucire 50/13 (G50/13) was assessed to develop controlled release formulation of salbutamol sulphate (SBL) a highly water soluble drug by semisolid matrix filling capsule technique. Drug release profiles of SBL release by using G50/13 and its blends with other hydrophilic or hydrophobic materials were investigated. Lipid matrix formulations prepared with increasing amount of polymer showed a s...

Gelucire is the family of vehicle derived from mixtures of mono-, diand tri-glycerides with PEG esters of fatty acids. They have a wide variety of application in pharmaceutical formulations. These are used in the preparation of fast release and sustained release formulations. In order to increase the bioavailability of drugs, the residence time of the orally administered dosage form in the uppe...

A solid dispersion of Meloxicam (MX), a poorly soluble, non steroidal anti-inflammatory drug, and Gelucire 50/13 was prepared by spray drying. Spherical microparticles were yielded with smooth surfaces as observed by scanning electron microscopy. According to differential scanning calorimetry and powder X-ray diffractometry analysis, MX was transformed from the crystalline state to the amorphou...

the objective of this work was to develop and evaluate the levofloxacin hemihydrate floating formulations (f1-f9). selection of optimized batch was done by model dependent approach and novel mathematical approach. f1-f9 batches were prepared by direct compression method using gelucire 43/01 (hydrophobic) and hydroxypropylmethylcellulose (hydrophilic) polymer in different ratios. the floating ta...

The challenge in developing oral drug delivery systems of poorly soluble basic drugs is primarily due to their pH dependent solubility. Cinnarizine (CNZ), a model for a poorly soluble basic drug, has pH dependent solubility; where it dissolves readily at low pH in the stomach and exhibits a very low solubility at pH values greater than 4. It is also characterized by a short half life of 3-6h, w...

The aim of this investigation was to improve the dissolution properties of the water-insoluble drug ezetimibe (EZE) and potentially improve bioavailability. A combination of melt and adsorption techniques was employed for the preparation of solid dispersions. PEG 4000, PEG 6000, and Gelucire 44/14 were used as hydrophilic carriers, and lactose monohydrate was used as an adsorbent. Phase solubil...

Non steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed medications to the geriatric patients for the treatment of arthritis and other painful disorders. The major side effects of NSAIDs are related to their effects on the stomach and bowels. The present study concerns assessment of the potential of liquid in situ gelling emulsion formulations (emulgels) as patient compliant stom...
