Solubility Estimation for Drugs Treated with the Simple Suspension Method Using Available Dissolution Test Profiles

[Improvement of dissolution test using microdialysis method].

Dissolution testing is a core performance test in pharmaceutical development and quality control. Generally, the HPLC method uses the analysis of dissolution testing. In this study, we attempted to improve the dissolution test by using microdialysis methods. We also investigated the comparison of the conventional HPLC dissolution method (batch-sampling method) and the improved dissolution test ...

Evaluation of Dissolution Hydrodynamics in the USP, PeakTM and Flat-Bottom Vessels Using Different Solubility Drugs

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

pH-metric solubility. 3. Dissolution titration template method for solubility determination.

The main objective of this study was to develop an effective potentiometric saturation titration protocol for determining the aqueous intrinsic solubility and the solubility-pH profile of ionizable molecules, with the specific aim of overcoming incomplete dissolution conditions, while attempting to shorten the data collection time. A modern theory of dissolution kinetics (an extension of the No...

Dissolution rate and apparent solubility of poorly soluble drugs in biorelevant dissolution media.

A series of poorly soluble BCS class II compounds with "grease ball" characteristics were assessed for solubility and dissolution rate in biorelevant dissolution media (BDM) with the purpose of investigating which molecular structures gain most in solubility when dissolved under physiologically relevant conditions. The compounds were studied in four media (simulated intestinal fluid in fasted (...
