Diphenidol

Diphenidol is a non-selective muscarinic M1-M4 receptor antagonist, has anti-arrhythmic activity. Diphenidol is also a potent non-specific blocker of voltage-gated ion channels (Na+, K+, and Ca2+) in neuronal cells. Diphenidol can be used in the study of antivertigo and antinausea[1][2][3][4][5].
