In vitro Evaluation of Novel Sustained Release Microspheres of Glipizide Prepared by the Emulsion Solvent Diffusion-Evaporation Method
The objective of the current investigation is to reduce dosing frequency and improve patient compliance by designing and systematically evaluating sustained release microspheres of Glipizide. An anti-diabetic drug, Glipizide, is delivered through the microparticulate system using ethyl cellulose as the controlled release polymer. Microspheres were developed by the emulsion solvent diffusion-eva...

Abstract Introduction: Preparation of tramadol HCl sustained release delivery system as an analgesic drug could improve its efficacy, reduce side effects and increase patient compliance. Objective: The aim of the present study was to prepare tramadol HCl loaded microspheres and coat them by solvent evaporation (ESE) method, in order to obtain an appropriate sustained release behavior and to p...
متن کاملPreparation of Eudragit E100 microspheres by modified solvent evaporation method.
The objective of this investigation was to develop the hollow microspheres as a new dosage form of floating drug delivery system with prolonged stomach retention time. Hollow microspheres containing ranitidine hydrochloride were prepared by solvent evaporation method using Eudragit RLPO dissolved in a mixture of dichloromethane and ethanol. The maximum yield and drug loading amount of hollow mi...

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
15 صفحه اولEffect of Thickness on the Structural Properties of Tellurium Film Prepared by Thermal Evaporation
In this research, tellurium (Te) film with thicknesses of 100-250 nm were deposited on ceramic substrates by thermal evaporation at 373 K. The thickness of the film was determined by Rutherford backscattering spectroscopy. The influence of the thickness on the structural, morphological and molecular bonds was characterized using XRD, scanning electron microscope, and Raman spectroscopy. The XRD...
