Application

Pyrilamine maleate salt has been used:
  • to treat Cassiopea sp. as H1 receptor antagonist
  • to intraperitoneally inject mice to prevent the release of endogenous histamine
  • in membrane binding assay to determine the Ki values and in the comparative inhibitory concentration (IC50) studies by whole-cell patch clamp technique

Biochem/physiol Actions

Pyrilamine maleate is a H1 histamine receptor antagonist. Pyrilamine maleate induces sleep in vertebrates. In Cassiopea, it induces concentration dependent dormancy.
