How to use
In Vitro:
Emedastine is capable of potently inhibiting histamine-induced cytokine release as well as the chemotaxis of eosinophils, thereby influencing factors contributing to the inhibition of the signs and symptoms of allergic diseases.
In Vivo:
In human, the half-life of emedastine, when administered as slow release capsules is of about 6±7 h.
