INHIBITOR->OFF-TARGET
HNMT inhibitors may increase histamine levels in peripheral tissues and exacerbate histamine-related diseases, such as allergic rhinitis, urticaria, and peptic ulcer disease. However, the effect of HNMT inhibitors on brain function is not yet fully understood. Some studies suggest that an increase in brain histamine levels by novel HNMT inhibitors could contribute to the improvement of brain disorders.
