Description

Caroverine HCl is a nonselective NMDA and AMPA glutamate receptor antagonist, also acting as a class B calcium-channel-blocker. Pharmacologically, it has been described as a nonspecific calcium channel blocker and as an antagonist of both non-NMDA and NMDA glutamate receptors. It was discovered in Austria in the 1950s[3]

How to use

In Vitro:

Caroverine (1 μM; pretreated for 10 min) inhibits the pressor response to KCl (80 mM) and noradrenaline (1 μM) in the rat hindquarter preparation. Caroverine markedly suppresses the contraction caused by KCl (40 mM) in the rat isolated aorta.

In Vivo:

Caroverine (1.44 mg/rat; s.c; 1.0 mL/h for 72 h) attenuates impulse noise-induced hearing loss in the rat.
