  • HPMC-Kapseln sind nicht magensaftresistent, das bedeutet, sie lösen sich bereits im Magen auf und geben so die Inhaltsstoffe frei.

    Magensaftresistente Kapseln können zwar ebenfalls aus HPMC bestehen, sie sind aber zusätzlich noch mit synthetischen Stoffen überzogen, die der Magensäure standhalten. Die Idee hinter solchen Kapseln ist, dass sie sich im Dünn- bzw. Dickdarm auflösen und dort erst die Inhaltsstoffe freigeben. Dies ist dann sinnvoll, wenn bspw. das saure Milieu des Magens die Wirkstoffe zerstören würde. Die Einnahme solcher Kapseln sollte aber immer mit dem behandelnden Arzt bzw. der Ärztin abgesprochen werden, da die Anwendung genau beachtet werden muss.
