Description

Application

Pyrilamine maleate salt has been used:

• to treat Cassiopea sp. as H₁ receptor antagonist[1]
• to intraperitoneally inject mice to prevent the release of endogenous histamine[2]
• in membrane binding assay to determine the K_i values and in the comparative inhibitory concentration (IC₅₀) studies by whole-cell patch clamp technique[3]

Biochem/physiol Actions

Pyrilamine maleate is a H1 histamine receptor antagonist. Pyrilamine maleate induces sleep in vertebrates. In Cassiopea, it induces concentration dependent dormancy.[1]
