Descripción general

Mepyramine maleate, a first generation antihistamine, is an antagonist of histamine H1 receptor, with Kds of 0.8 nM, 5200 nM and >3000 nM for H1, H2, and H3 receptor, respectively, and a pKd of 9.4 for H1 receptor.

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

Nota

Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
