A 54mg tablet of Concerta, which uses OROS technology. 22% of the drug is contained in the red overcoat, while the remaining 78% is split between two drug layers of differing concentration. The tablet uses an additional push layer that expands as water enters the tablet via the osmotic membrane. The drug is expelled via the laser-drilled hole visible on the left side of the tablet. The osmotic-controlled release oral delivery system (OROS) is an advanced controlled release oral drug delivery system in the form of a rigid tablet with a semi-permeable outer membrane and one or more small laser drilled holes in it. As the tablet passes through the body, water is absorbed through the semipermeable membrane via osmosis, and the resulting osmotic pressure is used to push the active drug through the opening(s) in the tablet. OROS is a trademarked name owned by ALZA Corporation, which pioneered the use of osmotic pumps for oral drug delivery. insulin-dependent diabetes or adult-onset diabetes) commonly begins as insulin resistance, with cells using insulin incorrectly.
