Examples

“Like⟳ batrachotoxin and veratridine, grayanotoxins act at the voltage-dependent sodium channel in its open⟳ conformation, inhibiting its inactivation.”

“2013, Thomas D. White, The Demonstration and Measurement of Adenosine Triphosphate Release⟳ from Nerves, David Paton (editor), Methods in Pharmacology, Volume 6: Methods Used in Adenosine Research⟳, page 47, The veratrum alkaloid, veratridine, depolarizes excitable tissues by activating the Na⁺ channels present⟳ in the cell membranes. Therefore, one would expect⟳ veratridine to produce⟳ a depolarization of nerve that is quite similar to physiological depolarization insofar as it is mediated by changes in Na⁺ conductances.”

“2013, Domingo M. Aviado, The Lung Circulation, Volume 1: Physiology and Pharmacology, page 39, The results from veratridine will be described first because they illustrate⟳ the ultimate way of obtaining proof that the carotid sinus baroreceptors can respond⟳ to foreign chemical agents.”
