   Professor Ping Lee and PhD graduate Dajun Sun recently published a paper, “Probing the mechanisms of drug release from amorphous solid dispersions in medium-soluble and medium-insoluble carriers,” that was featured on the cover of the Journal of Controlled Release.




   Using a simple but clever experimental design to control polymer solubility and drug release mechanisms, this study differentiates the dissolution and supersaturation behaviours of amorphous solid dispersions in medium-soluble and medium-insoluble polymer carriers by altering their pH. In so doing, Professor Lee and Dr. Sun show that the supersaturation profile of the medium-insoluble carriers are distinctively different than those based on conventional medium-soluble carriers, as they lack the initiation surge of supersaturation and provide extended sustained release properties without the use of crystallization inhibitors.


   In the commentary that accompanies this study, Journal of Controlled Release editor-in-chief Professor Kinam Park notes how this is “an important discovery” by the Lee group that “mechanistic insights gained here should open new avenues for improving the in vivo supersaturation behaviors of poorly water-soluble drugs through selecting appropriate medium-soluble and/or medium-insoluble ASD carriers.”

“Accolades for Professor Ping Lee”- Professor Ping I. Lee, GlaxoSmithKline Chair in Pharmaceutics and Drug Delivery has recently been recognized for his many achievements in the field of pharmaceutical sciences. At the American Association of Pharmaceutical Scientists’ Annual Meeting and Exposition in San Antonio, Texas this month, Dr. Lee was conferred the title of Fellow for his sustained remarkable scholarly and research contributions to the pharmaceutical sciences. The American Association of Pharmaceutical Scientists bestows the honour of Fellow to individuals who elevate the stature of the pharmaceutical sciences, demonstrate superior professional excellence, and have made exceptional contributions within their specific fields. Dr. Lee’s accomplishments are also referenced in the journal article “Historical perspective on advanced drug delivery. How engineering design and mathematical modeling helped the field mature” in Advanced Drug Delivery Review 65 (2013)

“University of Toronto grants exclusive rights to Wound Healing Technology to Cardium Therapeutics”- Dr. Ping Lee, a Professor at the University of Toronto’s Leslie Dan Faculty of Pharmacy and GlaxoSmithKline Chair in Pharmaceutics and Drug Delivery and his team have created a new sustained-release form of nitric oxide (NO) that can not only stop the infections at the wound sites, but also has the potential to speed up wound-healing… Cardium Therapeutics Inc. (Amex: CXM) of San Diego [www.cardiumthx.com] acquired the rights to use this Canadian discovery to expand its wound-healing portfolio, which includes dressings, topical creams and gels, and electrospun fibers for bandages.

Dr. Ping Lee, the GlaxoSmithKline Chair in Pharmaceutics and Drug Delivery, was recently quoted in a number of online stories, including Market Watch and The Medical News. In 2009, Dr. Lee aligned with MaRS Innovation to commercialize the novel nitric oxide sustained release technology developed in his laboratory. Cardium Therapuetics has now gained exclusive access to commercial development rights for this wound healing and tissue regeneration technology.

“Polymers may aid drug absorption”- Getting the right drug at the right time is key for almost any patient but making sure the drug is actually being absorbed properly by the body is even more important. Pharmacy Professor Ping Lee and his team are looking at ways to “get that medicine down” and improve how the body absorbs several poorly soluble drugs.
