Based on your basic understanding of the USP approach to dissolution, this course provides a foundation for the development and validation of drug dissolution, disintegration, and release methods used in product development, batch release, and stability testing. These tests are in vitro performance tests for most dosage forms such as tablets, capsules, suspensions, transdermal patches and suppositories. They are important components of specifications that establish a drug’s strength, quality, purity, and bioavailability. This course has been fully revised to reflect the content of the revised USP General Chapter <1092> published in USP 38–NF 33 ( First Supplement) with the official date of August 1, 2015.
