Abstract
A bioequivalence study was performed with two different 8-MOP preparations. Thirty-eight patients participated in the investigation. We compared a product already marketed containing a micronized powder in hard gelatine capsules with a new product in soft gelatine capsules containing the 8-MOP in a solution. With the new galenic preparation the serum level obtained was 3.2 (P≤0.01) times higher than with the old product. Thus, the improved resorption out of the solution was mainly responsible for these results. Es wurde eine Studie zur Bioverfügbarkeit von 8-MOP an 38-Psoriasispatienten durchgeführt. Zur Anwendung kamen ein handelsübliches 8-MOP-Präparat, das den Wirkstoff in Form eines mikronisierten Pulvers in Hartgelatinekapseln enthielt und ein 8-MOP-Präparat mit neuer Galenik in gelöster Form, abgefüllt in Weichgelatinekapseln. Mit der neuen galenischen Zubereitung konnten bereits nach einer halben Stunde um den Faktor 3,2 (P≤0.01, Wilcoxon Test) höhere und stabilere 8-MOP-Serumspiegel erzielt werden, wofür in erster Linie die verbesserten Resorptionsbedingungen verantwortlich sind.This publication has 16 references indexed in Scilit:
