Biochem/physiol Actions

Suplatast tosylate is a dimethylsulfonium compound downregulates the expression of histamine H1 receptor gene, suppresses the activity of histidine decarboxylase and regulates IL-4 mRNA. It inhibits the release of histamines and regulates the production of IgE.1,2 Suplatast tosylate is effective in the treatment of mild-to-moderate persistent asthma in children.3
Suplatast tosylate is an anti-allergy, cytokine modulator.
