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...
