Multilayer Tablet Technology, VersaTab™
Due
to low manufacturing costs and ease of administration, tablets continue
to be a preferred dosage form for controlled-release applications.
Controlled-release tablets are oral dosage forms from which the active
is released over an extended period of time (up to 24 hours) upon
ingestion. This allows a decrease in the dosing frequency and a
reduction in peak plasma concentrations, thereby improving patient
compliance and reducing the risk of undesired side effects.
Conventional single layered tablets have been traditionally used to
deliver active molecules into the blood stream. However, these
conventional single layered tablets present less than optimal delivery
characteristics such as non-linear delivery profiles of the active
ingredients, which can potentially lead to higher side effects.
IntelGenx has developed a multilayered technology which eliminates most
of the inconveniences of the single layered tablet and offers
wide-ranging flexibility.
Advantages of IntelGenx’ VersaTab™ Technology
- Linearization of the release profile using controlled erosion of inactive cover layers
- Multiple actives with independent release profiles
- Separation of active ingredients - avoidance of chemical incompatibility in fixed-dose combinations
- Cost-effective manufacturing
- Suitable for a wide range of API’s
- Improved patient compliance due to reduced dosing frequency
- Broad patent coverage
