Caroverine is a spasmolytic drug used in tinnitus treatment improves mechanosensitivity and mechanotransduction phenomenon and otoneuroprotective agent. Caroverine acts as an N-type calcium channel blocker, competitive AMPA receptor antagonist, and non-competitive NMDA receptor antagonist. When excessive glutamate binds to NMDA receptors, the receptor opens and allows calcium and sodium to enter the neuron, abnormal levels of calcium disturbs ionic balance causing spontaneous depolarization state. Pathological spontaneous depolarization state is reversed back to physiological polarization state by antagonistic property of Caroverine.

In Vivo Use Guide

Adult: 20-40 mg 3-4 times daily. Max: 200 mg/day. Max Dosage: 200 mg daily.

Route of Administration: Oral

In Vitro Use Guide

Cytotoxicity of caroverine in HNSCC cell lines was assessed using the Cell Counting Kit-8 (CCK-8, Dojindo Molecular Technologies Inc., Rockville, MD, USA). Briefly, 3 9 103 cells were seeded into 96 well plates and allowed to rest for 24 h. Caroverine was dissolved in dimethyl sulfoxide (DMSO) and diluted to concentrations ranging from 50 to 500 mkM. Cells were incubated with increasing doses of caroverine and after 72 h, cell viability was measured using the CCK-8 kit according to the manufacturer’s protocol.
