Class / Mechanism of Action
Antianginal agent, Vasodilator
Induces smooth muscle relaxation and vasodilation of peripheral veins and arteries and coronary arteries
thus improving collateral blood flow to ischemic regions of the myocardium. Reduces cardiac oxygen
demand by decreasing preload. Onset of action: Sublingual tablet and spray, 1-3 minutes. Duration: 25
minutes
Indications
Labeled Indications: Treatment or prevention of angina pectoris
Contraindications
• Hypersensitivity to nitrates or any component of the formulation
• Use with phosphodiesterase-5 inhibitors (Sildenafil, Levitra, Cialis) in previous 48 hours
• Increased intracranial pressure
• Hypotension (SBP <90mmHg or >30mmHg below baseline), Bradycardia <50bpm, Tachycardia
without heart failure (>100bpm), and Right ventricular infarction.
Adverse Reactions / Precautions
• IV/IO access should be placed and SBP should be >110.
o Use cautiously in cases of chest pain unless inferior wall / right-ventricular MI can be
ruled-out by ECG prior to administration
• Can cause severe hypotension with associated paradoxical bradycardia and increased angina
• Use with caution in volume depleted patients
• Do not use for inferior wall MI and suspected right ventricular involvement
