rience additive hypotensive effects.
Caffeine; Ergotamine: Ergot alkaloids are contraindicated in patients with hypertension, angina, or coronary artery disease; which are the primary patient populations for which nitroglycerin is utilized. Because of the potential to cause coronary vasospasm, ergot alkaloids can oppose the vasodilatory actions of nitroglycerin and, in doing so, may precipitate angina. In addition, oral administration of nitroglycerin decreases the first-pass metabolism of dihydroergotamine, thereby increasing its oral bioavailability.
Calcium-channel blockers: Nitroglycerin can cause hypotension. This action may be additive with other agents that can cause hypotension such as calcium-channel blockers. Patients should be monitored more closely for hypotension if nitroglycerin, including nitroglycerin rectal ointment, is used concurrently with a calcium-channel blocker.
Carbetapentane; Chlorpheniramine; Phenylephrine: Concomitant use of nitrates with sympathomimetics can result in antagonism of the antianginal effects of nitrates. In addition, amyl nitrite can block the alpha-adrenergic effects of epinephrine, possibly precipitating tachycardia and severe hypotension.
Carbetapentane; Diphenhydramine; Phenylephrine: Concomitant use of nitrates with sympathomimetics can result in antagonism of the antianginal effects of nitrates. In addition, amyl nitrite can block the alpha-adrenergic effects of epinephrine, possibly precipitating tachycardia and severe hypotension.
Carbetapentane; Guaifenesin; Phenylephrine: Concomitant use of nitrates with sympathomimetics can result in antagonism of the antianginal effects of nitrates. In addition, amyl nitrite can block the alpha-adrenergic effects of epinephrine, possibly precipitating tachycardia and severe hypotension.
Carbetapentane; Phenylephrine: Concomitant use of nitrates with sympathomimetics can result in antagonism of the antianginal effects of nitrates. In addition, amyl nitrite can block the alpha-adrenergic effects of epinephrine, possibly precipitating tachycardia and severe hypotension.
Carbetapentane; Phenylephrine; Pyrilamine: Concomitant use of nitrates with sympathomimetics can result in antagonism of the antianginal effects of nitrates. In addition, amyl nitrite can block the alpha-adrenergic effects of epinephrine, possibly precipitating tachycardia and severe hypotension.
Carbetapentane; Pseudoephedrine: Concomitant use of nitrates with sympathomimetics can result in antagonism of the antianginal effects of nitrates. In addition, amyl nitrite can block the alpha-adrenergic effects of epinephrine, possibly precipitating tachycardia and severe hypotension.
Carbinoxamine; Dextromethorphan; Pseudoephedrine: Concomitant use of nitrates with sympathomimetics can result in antagonism of the antianginal effects of nitrates. In addition, amyl nitrite can block the alpha-adrenergic effects of epinephrine, possibly precipitating tachycardia and severe hypotension.
Carbinoxamine; Hydrocodone; Phenylephrine: Concomitant use of nitrates with sympathomimetics can result in antagonism of the antianginal effects of nitrates. In addition, amyl nitrite can block the alpha-adrenergic effects of epinephrine, possibly precipitating tachycardia and severe hypotension.
