Uses for Cytalux
Cytalux injections are used to aid in the identification and removal of ovarian cancerous lesions that occur during surgery.
This medication is administered only under the supervision of a physician who has special training in near-infrared imaging (NIR) systems.
Cytalux contains pafolacianine sodium, a tetrasodium salt of pafolacianine, an optical imaging agent. Pafolacianine sodium has the chemical formula (S)-2-(4-((2-amino-4-oxo-3,4- dihydropteridin-6-yl)methyl)amino)benzamido). -3-(4-(((E)-2-((E)-2-(3,3-dimethyl-5-sulfonato-1-(4-\ssulfonatobutyl) -3H-indol-1-ium-2-yl)vinyl) hydrate of -6-((E)-2-(3,3-dimethyl-5-sulfonato-1-(4-sulfonatobutyl)indolin-2-ylidene)ethylidene)cyclohex-1-en-1-yl)oxy)phenyl)propanoate
Tetrasodium. Pafolacianine sodium has the following structure: C 61H 63N 9Na 4O 17S 4, a molecular mass of 1414.42 g/mol, and a molecular formula of C 61H 63N 9Na 4O 17S 4.
The intravenous solution of Cytalux (pafolacianine) injection is a sterile, non-pyrogenic, dark blue green, clear water solution. In a 1.6 mL volume, each vial contains 3.2 mg (2 mg/mL) pafolacianine (equal to 3.4 mg pafolacianine sodium), 14.4 mg sodium chloride, 0.23 mg potassium phosphate monobasic, 1.27 mg sodium phosphate dibasic heptahydrate, and 0.23 mg potassium phosphate monobasic. The pH is between 7.1 and 7.8 and is modified with sodium hydroxide and/or hydrochloric acid.

- Infusion-Related Reactions: Stop the infusion and use antihistamines and/or nausea drugs as needed.
- The presence of non-fluorescing tissue in the surgical field does not rule out the presence of a tumor, but it does raise the risk of misinterpretation. Non-cancerous tissues may show fluorescence.
- Toxicity to the fetus: Cytalux may harm the fetus. Inform females with reproductive potential of the risk to a fetus.
- Use just 5% Dextrose Injection to reduce the risk of Pafolacianine Aggregation and Infusion Reactions.
Dosage and administration
Recommended Testing, Prior to Administration of Cytalux
- Take a pregnancy test on females with reproductive potential to determine if there is no pregnancy.
prior to the administration of Cytalux
Do not stop taking folate, folic acid, or folate supplements at least 48 hours prior to taking the medication.
It is recommended to administer antihistamines and/or anti-nausea medications to prevent the effects of infusions.
Recommended Dosage and Administration
- The recommended dosage of Cytalux is an injection intravenously of 0.025 mg/kg, diluted to 250
