Application

Caramiphen hydrochloride has been used to test its inhibitory effect on voltage-gated Na+ currents using the patch-clamp method.

Biochem/physiol Actions

Caramiphen hydrochloride is non-narcotic and possesses many biological functionalities of being antitussive, anticonvulsive, and neuroprotective. It induces sensory block and displays less toxicity when compared to bupivacaine. The local anesthetic functionality of caramiphen is mediated by its inhibitory effect on voltage-gated Na+ currents.
Caramiphen is an anti-muscarinic similar to atropine; muscarinic acetylcholine receptor antagonist. Caramiphen is commonly used as a cough suppresant, but is also administered for the treatment of Parkinson′s disease. The compound has also been shown to have anti-depressant properties that may involve inhibition of G protein-coupled inwardly rectifying potassium channel GIRK.

Caramiphen is a muscarinic antagonist with potent anticonvulsant properties. Here, we investigated the efficacy of caramiphen against behavioural seizures and neuropathology induced by the nerve agent soman, and revealed two mechanisms that may underlie the anticonvulsant efficacy of caramiphen.

Sarin, a potent organophosphate cholinesterase inhibitor, induces an array of toxic effects including convulsions. Many antidotal treatments contain anticonvulsants to block seizure activity and the ensuing brain damage. Magnesium sulfate (MGS) is used to suppress eclamptic seizures in pregnant women
