Recent Techniques For Oral Time Controlled Pulsatile Technology

Abstract

Pulsatile drug delivery system is defined as the rapid and transient release of certain amount of drug molecules within a short time period immediately after a predetermined off-release period, i.e., lag time. [1] Pulsatile drug delivery aims to release drug on programmed pattern i.e. at appropriate time and at appropriate site of action. Pulsatile systems are gaining a lot of interest as the drug is released completely after defined lag time. Pulsatile drug delivery system is timeand site-specific drug delivery system, thus providing special and temporal delivery and increasing patient compliance.
