OROS: What you should know.

What is OROS?

Osmotic Controlled-Release Oral Delivery System releases
medicine over a course of time. The resulting osmotic
pressure is used to push the active drug through the laser
drilled opening(s) in the tablet and into the
gastrointestinal tract.



We constructed a case study over a time period of 6 minutes to compare the differences between OROS vs NON OROS tablets.

In this example the drilled pill dissolved before the undrilled pill
