Question
Osmotic pump products are becoming more practical with advances in the technology. Name the three examples of osmotic drug delivery systems.
Solution
-
Alzet Osmotic Pumps: These are small, implantable pumps that deliver drugs, hormones, and other test agents at controlled rates over durations ranging from one day to six weeks. They are used in research settings.
-
DuPont's Osmotic Delivery System (SODAS): This system uses an osmotic pressure difference across a semi-permeable membrane to deliver a drug at a controlled rate. The drug is contained in a core surrounded by a semi-permeable membrane with a delivery orifice.
-
ProNeura: Developed by Titan Pharmaceuticals, ProNeura is a long-term, continuous drug delivery system that consists of a small, solid rod made from a mixture of ethylene-vinyl acetate (EVA) and a drug substance. The rod is inserted subdermally and is designed to deliver drugs for up to one year.
