Advanced Technology

Each of these technologies has its own unique characteristics. These proprietary technologies enable the drug to achieve releases at different times, rates, and locations.

Mech-trol ®

Exponential release: Allows the achievement of various release profiles by only varying the processing parameters. It also generates release profiles from slow release to fast release.


Bi-lock ®

Immediate release of one layer and controlled release of the second layer: Generates a more stable physical bi-layer tablet and enables a combination of two releases from each layer.

(678) 309-5160

U-trol ®

Release at different times and rates: Enables a pulsatile release of multiple APLs in one unit to achieve a stable plasma concentration. An excellent solution for combination products with different releases.
