Hypertension is still one of the most serious global health problems and requires continuous management with medications used over long periods of time. Successful management of hypertension involves maintaining constant and consistent plasma levels of medication in order to achieve therapeutic effectiveness. The traditional methods of delivering medications via the oral route have not provided a mechanism for long-term, sustained and controlled release of medications throughout the duration of therapy. This can lead to inconsistent plasma concentrations of drugs and a lack of compliance by patients to their medication regimen. In light of this finding, transdermal drug delivery systems made of polymers present a new way to deliver antihypertensive medications due in part to their ability to control the rate of drug release from the device providing better therapeutic results.
This research will provide an analysis of the polymer engineering and controlled-release mechanisms involved in designing transdermal drug delivery systems for the delivery of antihypertensive drugs using an analytical approach that utilizes secondary data from the literature. The data collected for this research project will be obtained from published journal articles, pharmaceutical product databases and material science literature as well as examining new products involving polymeric drug delivery. The analysis will focus on four areas; 1) polymer types and matrix design, 2) controlled-release mechanisms used for the release of drugs including diffusion, swelling and erosion, and 3) new technologies including smart polymers and nanocomposites, 4) industrial and clinical implications associated with the manufacturing scalability, import/export regulations and regulatory issues related to these new products.
Research reveals that drug stability, permeability, and controlled release, and thus therapeutic consistency of drugs are greatly improved by polymer engineering. Advanced polymers and systems, particularly stimul-responsive and hybrid systems, also show much promise as viable means of improving the transdermal delivery of drugs. Nonetheless, the issues of pricing, reliability, and regulatory standardization continue to exist.
The findings suggest that integrating polymeric materials into pharmacokinetics will yield a strong basis for developing effective transdermal antihypertensive delivery systems. Thus, ongoing advancement and cooperative interdisciplinary efforts will propel this field into the future.
