Prediction of the Transdermal Delivery of ß-blockers

  • Chapter

Part of the book series: Frankfurter Seminare für Klinische Pharmakologie ((2742))

Summary

A simple kinetic model for predicting transdermal delivery is described. Basic physicochemical parameters of the therapeutic agent are required to allow simulation of the plasma levels of drugs following topical application. The rate at which the device releases drug to the skin surface is important and complex release patterns can be simulated using STELLA, a software application developed for the Apple Macintosh Computer. Examples of the modelling are provided for a series of ß-blockers and the influence of release characteristics and incorporated penetration enhancers is demonstrated.

Zusammenfassung

Zur Voraussage der transdermalen Resorptionsvorgänge wird ein einfaches kinetisches Modell vorgestellt. Notwendig dazu sind die physiko-chemischen Eigenschaften des Arzneistoffes, mit deren Hilfe die Plasmakonzentrationen nach topischer Applikation simuliert werden können. Hierbei ist entscheidend, mit welcher Geschwindigkeit das System den Arzneistoff an die Haut abgibt. Das komplette Freisetzungsprofil läßt sich mit Hilfe von STELLA simulieren. Es ist eine für den Apple Macintosh entwickelte Software. Beispiele werden für eine Reihe von Betablockern vorgestellt und der Einfluß der Freisetzungscharakteristik und der von inkorporierten „Enhancern“ demonstriert.
