Theoritin-MF Pharmacodynamics
Theoritin® MF (3-methyl-7-[4-(4-benzhydrylpiperazinyl-1)butyl] xanthine succinate) is a purine derivative with strong anti-allergic activity, associated with prolonged and selective blockade of H1 -histamine receptors, Theoritin® MF prevents and relieves allergic reactions. It has antipruritic and antiexudative effects. It has weak m-cholinoblocking and antiserotonin activity. It does not have sedative properties and does not affect the speed of psychomotor reactions. It is superior in activity and duration of antihistamine action as compared to first generation H1-histamine blockers – diphenhydramine, chifenadine and azelastine and second generation cetirizine, loratadine, fexofenadine, which was demonstrated on experimental model of Theoritin® MF effect on histamine spasmogenic action in guinea pig isolated ileum. Theoritin® MF is close to azelastine in its antiserotonin activity, which determines the antipruritic effect of this group of drugs and significantly exceeds the other drugs listed above.
