Study Notes
### OROS Tablet Design
- Small laser-drilled holes in OROS tablets serve as a precise entry point for water to enter.
- This controlled water entry is crucial for the osmotic pump mechanism to function.
Osmotic Release Systems
- Osmotic release systems offer a significant advantage over other controlled-release methods by maintaining a consistent drug release rate, independent of external factors like pH, enzymes, or the presence of food in the digestive system.
OROS Trademark
- The trademark "OROS" belongs to Alza Corporation, a company specializing in drug delivery technologies.
Osmotic Pump Mechanism
- The osmotic pump relies on a semi-permeable membrane that allows water to enter, while the drug itself remains trapped inside.
- As water enters the tablet, it creates pressure that pushes the drug through the laser-drilled holes, delivering a controlled and consistent dose over an extended period.
Advantage of Osmotic Pumps
- A notable advantage of using osmotic pumps is their ability to deliver drugs independently of gastrointestinal factors, ensuring consistent release and predictable therapeutic effects.
