Mechanisms compared
Prometrium: Progesteron in Prometrium bindet an Progesteronrezeptoren und moduliert die Genexpression in reproduktiven und anderen Geweben. Formoterol: Formoterol aktiviert selektiv Beta-2-adrenerge Rezeptoren der glatten Atemwegsmuskulatur und führt über eine cAMP-vermittelte Relaxation zur Bronchodilatation.
