“ Neostigmine administered after vitamin B6 (5.91 x 10(-8) and 1.48 x 10(-7) M) produces a mean contraction of 104.50 + 8.77 and 108.8 + 12.65 (mean + SD) compared with acetylcholine.”
“The contraction produced by the combination of vitamin B6 and neostigmine is greater and more prolonged than that produced by neostigmine alone.”
