ZOOM Online: Pharmaceutical Dissolution Testing - a 2 day Webinar

Register InterestNo Course Dates Currently Available


Dissolution and drug release tests are directly relevant to the safety and efficacy of many common pharmaceutical dosage forms. To achieve reliable and reproducible results, analysts must understand the importance correct equipment set-up, sample introduction and sampling. In addition to use of dissolution testers, this 2 day course will also cover equipment qualification, data evaluation and development and validation of dissolution procedures.

An optional half day will deal with use of dissolution testing in the assessment of bioavailability and bioequivalence.

Delegates will have the opportunity to set up and run dissolution tests using a USP I/II dissolution tester during the course and the course will include case studies and individual/group exercises.


After completing this course, trainees will be familiar with the different types of pharmaceutical dissolution testing equipment and understand the factors that must be considered when developing a test.
