A Total Error Approach for the Validation of Quantitative Analytical Methods

Posted by Anagha Kakade on Mar 13, 2017 10:15:00 AM

The total error approach is a statistical technique for assessing performance of analytical methods. It could be used for any lab data analysis in oncology or other clinical trials or for the testing of new drugs. Due to variable parameters involved in inter-laboratory transfer of clinical trials like analysts, instruments, day/sessions and geographic location, there are chances of different assignable and non-assignable causes of variations. Here, the statistical analysis of measurement processes helps to identify and quantify sources of variation. The total error approach evaluates the variability in the parameters and helps the scientist in decision making.

Dissolution Analyses: Comparison of Profiles Using f2 Analysis Calculation

Posted by Anagha Kakade on Sep 22, 2016 12:43:47 PM

A dosage form is the form in which a drug is produced and dispensed; for example, tablet, capsule or suspension. The rate and extent to which the amount of drug substance dissolved over a period of time is called dissolution. Dissolution testing is the primary pharmaceutical test that is designed to probe the performance of dosage forms.  The dissolution method developed is compared with the innovator’s reference product to evaluate the release pattern and establish the method comparison for estimating the drug release. The purpose of this article is to provide some insight into the comparison of dissolution profiles using f2 analyses.
