Phenthonium, a quaternary derivative of (-)-hyoscyamine, enhances the spontaneous release of acetylcholine at rat motor nerve terminals.

1. A quaternary derivative of (-)-hyoscyamine, phenthonium (Phen) induced a concentration-dependent increase in the rate of spontaneous quantal release of acetylcholine (ACh) at the mammalian neuromuscular junction, as shown by intracellular recordings of the miniature endplate potentials (m.e.p.ps)...
