Abstract

The basic purpose of constructing drug delivery systems is to design when and where the drug will be released. The episode of many biological events is really important for such knowledge. Metoprolol pulsatile drug delivery system was developed for this purpose, which can release the drug when blood pressure needs to be modulated in the early morning. The Cup and core techniques were used to build this system, which included immediate release (IR), sustained-release (SR), and a polycaprolactone plug layer. The formulation of the ingredients was facilitated by various preformulation studies. The IR and SR tablets were bilayered, with polycaprolactone entirely coating the IR layer. The IR and SR tablet release profiles were optimised for the F5 batch, which was then used to construct a pulsatile drug delivery system. Clinical trials were conducted with the prepared tablet, which included the use of BaSO4 tagged tablets for X-ray examinations. All of the findings indicated the optimal drug release of metoprolol, which can be used for individuals who are more prone to blood pressure abnormalities in the morning.
