- Mechanism of Action Nitroglycerin forms free radical nitric oxide. In smooth muscle, nitric oxide activates guanylate cyclase which increases guanosine 3’5’ monophosphate (cGMP) leading to dephosphorylation of myosin light chains and smooth muscle relaxation.

Nitroglycerin causes the relaxation of vascular smooth muscles, causing arteriolar and venous dilatation. 17 It increases blood flow to the myocardium and reduces cardiac preload and afterload, decreasing myocardial wall stress and ameliorating anginal symptoms. 3,10,12 Nitroglycerin also reduces coronary artery spasm, decreasing systemic ...

Note:Nitronal IV solution has been discontinued in the US for more than 1 year. Note:Hemodynamic and antianginal tolerance often develop within 24 to 48 hours of continuous nitrate administration. Nitrate-free interval (10 to 12 hours/day) is recommended to avoid tolerance development; gradually decrease dose in patients receiving nitroglycerin for...
Note:Nitronal IV solution has been discontinued in the US for more than 1 year. Note: Continuous IV infusion dosing units vary by age (mcg/kg/minute or mcg/minute); extra precautions should be taken. Tolerance to the hemodynamic and antianginal effects can develop within 24 to 48 hours of continuous use. Nitrate-free interval (10 to 12 hours/day) i...
Nitronal (glyceryl trinitrate) 1 mg/mL (temporarily available in the US): To prepare a 100 mcg/mL solution: Withdraw 25 mL D5W from a 250 mL bottle of D5W and replace volume with 25 mg (25 mL) of Nitronal. To prepare a 200 mcg/mL solution: Withdraw 50 mL D5W from a 250 mL bottle of D5W and replace volume with 50 mg (50 mL) of Nitronal.
IV: Prepare in glass bottles, EXCEL or PAB containers. Adsorption occurs to soft plastic (eg, PVC); use administration sets intended for nitroglycerin. Avoid in-line IV filters that adsorb nitroglycerin. Administer via infusion pump. Intra-anal ointment: Using a finger covering (eg, plastic wrap, surgical glove, finger cot), place finger beside 1 i...
Mechanism of action. Glyceryl trinitrate is a prodrug which must be denitrated, with the nitrite anion or a related species further reduced to produce the active metabolite nitric oxide (NO). Organic nitrates that undergo these two steps within the body are called nitrovasodilators, and the denitration and reduction occur via a variety of ...
