Descriere
In diesem Werk werden Mglichkeiten der Wirkstoffverabreichung dargestellt, wobei physikalische und pharmakokinetische Modelle zur Erzielung der gewnschten Profile und Anstze herangezogen werden. Nach einem berblick ber die Wirkstoffaufnahme und die physiologischen Modelle werden in den Kapiteln ber die oralen Verabreichungswege (die hufigste Form der Verabreichung) die PBPK und verschiedene mgliche Darreichungsformen beschrieben. Bei der systemischen transdermalen Verabreichung ist es notwendig, die Pharmakokinetik der Formulierung und des Wirkstoffs zu verstehen, um die Formulierung von der ersten Konzeption ber die gesamte Entwicklung darauf auszurichten. In weiteren Kapiteln werden die biologischen und praktischen Anstze bei der pulmonalen und mukosalen Verabreichung besprochen. Fr den Fall der Notfallversorgung betrachten die Autoren die Beziehung zwischen parenteralen Infusionsprofilen und PK/PD. In den letzten Kapiteln werden aktuelle Trends dargestellt, darunter virtuelle Experimente zur Verdeutlichung von Mechanismen sowie moderne Anstze in der Wirkstoffverabreichung und personalisierten Medizin.
