Sustained Release System
Ready-mix sustained release material where weight gain is the control variable and the profile holds batch to batch.
What this range covers
Sustained and controlled release drug delivery systems built on polymers and resins, supplied ready-mix so that release profiles can be reproduced batch to batch.

Application parameters
Rglax Coat film coating
Tablet bed and inlet temperatures are given as aqueous over non-aqueous (AQ / NAQ). Settings are indicative and confirmed against your core during trials.

Common questions
What controls the release rate with SR100?
Weight gain. Release rate follows the amount applied, so the build-up is the control variable. It is fixed at trial against your target dissolution profile, then held batch to batch.
Why supply it as a ready-mix?
Because in-house polymer blending is where extended release profiles drift between batches. A ready-mix removes that variable, so the profile you qualified is the profile you keep.
