Common questions
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.
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.
