Mechanism Of Action Isosorbide dinitrate is converted to the active nitric oxide to activate guanylate cyclase. This activation increases levels of cyclic guanosine 3′, 5′-monophosphate (cGMP) . cGMP activates protein kinases and causes a series of phosphorylation reactions which leads to dephosphorylation of myosin light chains of smooth muscle fibres. Finally there is a release of calcium ions which causes smooth muscle relaxation and vasodilation.
Description of the Drug: Isosorbide dinitrate is a vasodilator used to treat angina in coronary artery disease.
