How Indigo Carmine Free Acid works

Indigo carmine works as a dye that accumulates in crevices, cysts, and foveolae and stains the tissue blue .

According to one study, the primary action of indigo carmine appears to be at the level of nitric oxide generation and/or its release from the endothelium. In addition to this, indigo carmine appears to inhibit vascular smooth muscle guanylyl cyclase. Therefore, indigo carmine may increase blood pressure by interfering with these nitric oxide-mediated vasodilatory mechanisms .

Toxicity

After intravenous administration, the LD80 was measured at 300 mg/kg in the mouse .

Nausea, vomiting, hypertension, bradycardia and infrequently, rash, pruritus, and bronchoconstriction. Skin discoloration may occur at high doses. Anaphylaxis is a serious adverse event that has been occasionally reported .

Indigotindisulfonate sodium injection should be given to a pregnant woman only if absolutely necessary .

It is not known whether this drug is excreted in human breastmilk .

Food Interaction

No interactions found.

Elimination Route

Biologically inert .

Half Life

4-5 minutes post-injection

Elimination Route

Indigo carmine is excreted largely by the kidneys, retaining its blue color during passage through the body.

Elimination of this dye begins rapidly after injection, appearing in the urine within 10 minutes in most cases. Larger quantities are necessary when intramuscular injection route is employed. Appearance time and elimination are delayed if given by the route of intramuscular injection .
