“ Mg++ , DL-2-amino-5-phosphonopentanoic acid and MK-801 (D-5-methyl-10,11,dihydro-5H-dibenzo[a,d] cyclohepten-5-10-imine maleate), but not 6-cyano-7-nitroquinoxaline-2,3-dione, inhibited the L-glutamic acid-evoked release of NE.”

“The results indicate that in the pulmonary artery, Mg++ alters the sensitivity to histamine but not to norepinephrine, and may differentially inhibit bound Ca++ release by norepinephrine and histamine.”
“Phenytoin and the Mg2+ ion were found to have a marked inhibitor effect by increasing the threshold norepinephrine concentration and decreasing the maximal rate of depolarization of SR.”
