Innovations in Pharmaceutical Coating Development


There have been some major advances over the last 20 years in the use of polymeric excipients for film coating in solid oral dosages, including tablets, mini- tablets, soft and hard capsules, multi-particulates and powders. This webinar will provide a review of the main excipients and excipient properties that are important in instant release, sustained release and enteric release applications.

Immediate release film coatings are a commonly used to provide elegance, aesthetic appeal, taste masking of bitter drugs in the tablet formulations. In addition, film coating containing pigments are used for recognition and differentiation of different brands, drug types and strengths through color or a glossy appearance. Film coating also provides protection against light to protect light sensitive drugs. In recent years, new developments in film coating formulations have expanded their functionality to benefit a variety of different areas. These innovations include technologies that offer flexible manufacturing processes and high productivity to simplify product development, can provide enhanced moisture barrier protection to protect moisture sensitive actives (reduce degradants & cost of packaging), make tablets easier to swallow to improve patient adherence, or carry a covert taggant that can be used as an on-dose-authentication platform that ultimately protects against falsified medicines. Each of these topics will be presented with case studies to showcase how these new developments enhance tablet formulations & production from manufacturing to storage and ultimately patient acceptability and safety.

This webinar will include 2 hours of interactive presentations. We have invited academic, industry, and regulatory experts to provide different perspectives. We will allot approximately 35 minutes for each presenter. Discussion and Q&A will be encouraged throughout.
