Does ketotifen act by directly stimulating beta-adrenergic system?
Through this study we proved that the inhibitory effect ketotifen has on antigen-specific histamine release (ASHR) does not have any relation with beta-adrenergic system stimulation. However, it increases the inhibitory effect of histamine release caused by isoproterenol. Therefore, although ketotifen does not directly stimulate beta-adrenergic receptors to inhibit mediator secretion, its action correlates with the response produced through the stimulation of these receptors.
