The organic nitrates, including nitroglycerin, isosorbide dinitrate and isosorbide mononitrate, act as prodrugs for nitric oxide (NO) which is a potent vasodilator gas. Nitric oxide activates guanylyl-cyclase in vascular endothelial cells, which increases intracellular cyclic GMP and thereby reduces intracellular calcium concentrates and dephosphorylates myosin light chains causing relaxation of smooth muscle cells.
Ammonium nitrate (AN) is an odorless, colorless or white, crystal salt produced by the reaction of ammonia and nitric acid. It was the first solid nitrogen (N) fertilizer produced on a large scale.ertilizer prills are formed as drops of the concentrated ammonium nitrate solution (95 to 99 percent) fall from a tower and solidify. Low-density prills are more porous and are preferred for industrial or explosive use.
