The Pulsatile Drug Delivery System represents an innovative method for the targeted delivery of medications, allowing for a rapid and temporary release of active ingredients after a predetermined release time. This form of controlled drug delivery is particularly relevant for patients with specific conditions such as cardiovascular diseases, diabetes mellitus, asthma, arthritis, and ulcers, where conventional oral delivery systems may not be effective. By programming the release of the active ingredient at the appropriate time and place, the effectiveness of the treatment is maximized while minimizing unwanted side effects. The book provides a comprehensive overview of various technologies and methods used in the development of pulsatile delivery systems, highlighting their benefits for patient adherence and targeted drug administration.
