PROSOLV® EASYtab SP
Microcrystalline Cellulose, Colloidal Silicon Dioxide, Sodium Starch Glycolate, Sodium Stearyl Fumarate
Introduction
The health science industry faces a wide variety of challenges including increased pressure to:
- Reduce costs
- Accelerate time to market
- Improve product performance
These challenges drive health science companies to find new solutions for improving time- and cost-efficiency in oral dosage form development and production.
Formulation scientists developing direct compression formulations generally require several conventional excipients – often at high levels – to obtain good material flow, compaction, blending properties, content uniformity, carrying capacity, stability, lubricity, and disintegration. Finding the proper excipient combinations and concentrations to achieve adequate solid dosage formulas is a time-consuming, and often expensive process, that varies with active pharmaceutical ingredient (API) characteristics.
PROSOLV EASYtab SP was developed to provide an innovative solution to meet these challenges.
PROSOLV EASYtab SP presents a set of properties that make it well-suited for continuous processing. Because it acts multi-functionally as a filler/binder, flow aid, disintegrate, and lubricant at the same time, production requires only two feeders . This not only leads to space saving, but also helps to simplify control of the production process.
PROSOLV EASYtab SP unique surface structure and good flowability enable fast and segregation-free blending with APIs. Its all-in-one structure, using sodium stearyl fumarate as a lubricant, provides outstanding robustness in terms of blending times.
Compounding with PROSOLV EASYtab SP leads to a homogeneous distribution of the individual components throughout the particle and on its surface. The synergistic effects achieved by this technology include better compactability, flowability, and content uniformity, due to a significantly increased surface area.
What is PROSOLV EASYtab SP
Using the PROSOLV technology PROSOLV EASYtab SP is the first lubricated high functionality excipient on the market. It is an all-in-one, ready-to-use excipient composite. It effectively combines four individual components.
