Today, FDA published guidance titled “Good Manufacturing Practice Guidance for Active Pharmaceutical Ingredients – Questions and Answers.” FDA explains that, since ICH Q7 has published, there have been many questions raised by firms, both domestic and international, requesting clarification on issues raised in the ICH document. The Q&A document referenced above responds to those questions. […]
On April 18, 2018, the FDA issued a revised draft guidance on Metered Dose Inhalers and Dry Powder Inhalers titled “Metered Dose Inhaler (MDI) and Dry Powder Inhaler (DPI) Products – Quality Considerations Guidance for Industry”. The original guidance was published November 13, 1998. The revision spans some 50 pages of discussion about critical quality […]
With all the discussions of reducing prescription costs, the importation of drugs from Canada almost always appears in the debate. While there are many reputable Canadian on-line and brick and mortar pharmacies from which to import prescription drug products, I have never thought that it was a good idea. ABC News (here) seem to validate […]
The FDA has struggled with the best methods to determine the bioequivalence of topical dermatological drug products for years. For example, FDA considered numerous methods including transepidermal water loss (TEWL), skin stripping, and others to demonstrate the bioequivalence of retinoid acne products.

March approvals appear to be moving in the right direction as firms, apparently, are catching up with elemental impurity issues and their amendments are working their way through the review and approval process. Unofficial March ANDA approval numbers taken from the Recent New and Generic Drug Approvals list (here) show 50 full approvals and 10 […]
It has been just about 11.5 years since FDA approved an OTC version of MiraLAX and the innovator withdrew the Rx-labeled NDA product from the market. Why did it take this long? Other than the fact that ANDAs approved prior to the approval of the OTC version were making significant profits, there were differences between […]
