Acetazolamide Tablets and Sodium Nitrite

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

When use of sodium nitrite is required, the doctor should be told if you have been receiving treatment with acetaZOLAMIDE. Sodium nitrite can cause hypotension (low blood pressure), and the risk may be greater when combined with other medications that decrease blood pressure such as acetaZOLAMIDE. Excessively low blood pressure can lead to shock, collapse, coma, or even death. Your doctor will need to monitor you closely and possibly take extra precautions for you to safely use these medications together. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

MONITOR: Coadministration with antihypertensive agents, diuretics, vasodilators, or phosphodiesterase-5 (PDE5) inhibitors may potentiate the hypotensive effect of sodium nitrite. Since sodium nitrite can cause serious hypotension and methemoglobin formation, patients may be at increased risk for complications related to inadequate perfusion and oxygenation. In healthy volunteers, oral doses of 120 to 180 mg caused minimal cardiovascular changes when subjects were maintained in the horizontal position. However, subjects exhibited tachycardia and hypotension with syncope within minutes after being placed in the upright position. A wide range of methemoglobin concentrations may occur following sodium nitrite administration. Methemoglobin concentrations as high as 58% have been reported after administration of two 300 mg doses to an adult. There have been reports of severe hypotension, methemoglobinemia, cardiac dysrhythmias, coma, and death in patients without life-threatening cyanide poisoning but who were treated with injection of sodium nitrite at dosages less than twice those recommended for the treatment of cyanide poisoning.

MANAGEMENT: Sodium nitrite should be used with caution in the presence of concomitant antihypertensive agents, diuretics, vasodilators, or PDE5 inhibitors . Hemodynamics should be monitored during and after administration of sodium nitrite, and the infusion rate decreased if significant hypotension occurs. In addition, methemoglobin levels should be monitored and oxygen administered during treatment whenever possible.
