Pharmaceutical Technology® Europe spoke with Ali Rajabi-Siahboomi, vice president and chief innovation officer at Colorcon, about the evolution of coating design and how it has impacted investment, as well as innovations in packaging for oral solid dosage products.
Coating design for solid dosage products has evolved from sugar coating to film coating to solvent-based and then to aqueous coating over the years, according to Rajabi-Siahboomi. “But the development of this robust and optimized formulation that we've had, and the umbrella of the Opadry system, has made it much easier to have the right film coating, but at the same time, apply it much more efficiently,” he says.
The functionalities of film coating have changed over the years as well, according to Rajabi-Siahboomi. “Many years ago, [film coating] was just more for adding color and recognizing different dosages and different product. Nowadays, we apply functionalities [such as] moisture barrier … putting tags in those film coating so that we can identify them as part of authentication and counterfeiting, anti-counterfeiting. So, there has been a whole evolution, but when we talk about some of these challenges, … it highlights the need for continuously focusing on innovating, bringing continuous improvement and innovation in this field.”
