ABSTRACT
Controlled release of drugs is a dynamic activity of pharmaceutical companies, due to the
indisputable advancement provided by delivery technology to pharmacotherapy. In
addition, this activity give rise to new patented products for a market in which new
substances are reducing and the approved ones more and more face dispensing problems.
Today, no drug product enters the market without its own delivery program built in. In
front of this requirement, pharmaceutical technology researchers proposed the so called
drug delivery “technology platform,” i.e., drug administration based on the use of devices
capable to contain, meter and deliver the drug at appropriate rate and duration.
