Dissolution profile comparison
How to compare dissolution profiles between different dissolution models?
To allow application of these models to comparison of dissolution profiles, the following procedures are suggested: 1. Select the most appropriate model for the dissolution profiles from the standard, pre-change, approved batches. A model with no more than three parameters is recommended.
What is the rate of dissolution for BCS-based biowaivers?
In vitro Dissolution for BCS-based Biowaivers either very rapid (> 85 % within 15 min) or similarly rapid (85 % within 30 min ) in vitro dissolution characteristics for BCS class I and III Similarity of dissolution profiles
What is the pH of in vitro dissolution test?

dissolution profile comparison may be carried out using model independent or model dependent methods (EMEA, 2001). An extended-release dosage form requires at least three test time points to characterize the in vitro drug release profile. An early time point, usually consisting of 1 to 2 hours, is used to show that there is little probability

The lag time of the dissolution profile is related to the drug solubility in the dissolution media and the method of drug entrapment. The presence of lag time in the dissolution profile of particle size ranges 500-400 µm and 315-80 µm of microcapsules prepared by using 20 % and 33.33% TDC may be due to the molecular dispersion and minute drug ...
