About This Medication

11 DESCRIPTION BLUDIGO (indigotindisulfonate sodium injection, USP) is a sterile deep blue or bluish-purple diagnostic dye for intravenous use. Each mL contains 8 mg indigotindisulfonate sodium (equivalent to 7.2 mg indigotindisulfonate) and may also contain citric acid and sodium citrate to adjust pH value between 3 and 6.5 and has an osmolality ≤ 0.05 osmol/kg. Indigotindisulfonate sodium is also known as indigo carmine. The chemical name of indigotindisulfonate sodium is Disodium 3,3’-dioxo-[Δ 2,2’ -biindoline]-5,5’-disulfonate. Its molecular formula is C 16 H 8 N 2 Na 2 O 8 S 2 and its molecular weight is 466.35 g/mol. Its structural formula is: indigotindisulfonate sodium image description

Indications & Usage

1 INDICATIONS AND USAGE BLUDIGO is indicated for use as a visualization aid in the cystoscopic assessment of the integrity of the ureters in adults following urological and gynecological open, robotic, or endoscopic surgical procedures. BLUDIGO is a diagnostic dye indicated for use as a visualization aid in the cystoscopic assessment of the integrity of the ureters in adults following urological and gynecological open, robotic, or endoscopic surgical procedures.

How It Works

12.1 Mechanism of Action Indigotindisulfonate is a dye excreted by the kidney through tubular secretion and enhances visualization of the ureteral orifices by its deep blue color.

Dosage & Administration

2 DOSAGE AND ADMINISTRATION Recommended dose is 5 mL given intravenously over 1 minute. ( 2.1 ) Monitor blood pressure and heart rhythm during and after injection. ( 2.2 ) 2.1 Recommended Dosage The recommended dose of BLUDIGO is 5 mL given as an intravenous injection over 1 minute. The blue color is detectable at the ureteral orifices within 4 minutes to 9 minutes after the intravenous injection. 2.2 Important Administration Instructions Monitor blood pressure and cardiac rhythm during and following the injection [see Warnings and Precautions ( 5.1 )]. Use immediately after opening ampule. Withdraw the contents of the ampule through a 5 micron or smaller filter straw/filter needle to ensure that the withdrawn solution contains no particulates. The withdrawn solution should be inspected visually for particulate matter and discoloration prior to administration. Do not administer with infusion assemblies used with other diluents or drugs. Discard any unused portion.

Side Effects Overview

6 ADVERSE REACTIONS Clinically significant adverse reactions are described elsewhere in the labeling: Cardiovascular Reactions [see Warnings and Precautions ( 5.1 )] Hypersensitivity Reactions [see Warnings and Precautions ( 5.2 )] Adverse reactions (≥ 1%) are constipation, nausea, vomiting, abdominal pain, pyrexia, ALT increase, and dysuria. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact PROVEPHARM Inc at 1–833-727-6556 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of BLUDIGO was evaluated in a randomized, intra-patient controlled, blind to dose of BLUDIGO, clinical trial. A total of 118 adult patients undergoing endoscopic urological or gynecological procedures were treated intravenously; 58 (49%) of these patients received one dose of BLUDIGO 2.5 mL and 60 (51%) of patients received one dose of BLUDIGO 5 mL. The 2.5 mL dose is not approved [see Dosage and Administration ( 2.1 )] . The mean age of patients was 51 years and 35 (30%) patients were 65 years of age or older. The majority of patients were White 105 (89%) and female 87 (74%). The adverse reactions (≥1%) reported in the clinical trial are provided in Table 1. Table 1. Adverse Reactions Reported at ≥1% of Patients Receiving BLUDIGO 5 mL Intravenously BLUDIGO 5 mL (N=60) n (%) Constipation 3 (5.0) Nausea 2 (3.3) Vomiting 2 (3.3) Abdominal Pain 2 (3.3) Pyrexia 2 (3.3) ALT increase 2 (3.3) Dysuria 1 (1.7) 6.2 Postmarketing Experience The following adverse reactions have been identified following the use of indigotindisulfonate sodium injection products. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Cardiovascular disorders: cardiac arrest, arrhythmia, asystole, atrioventricular block second degree, hypotension, elevation in blood pressure, bradycardia, tachycardia General disorders and administration site conditions: injection site discoloration Immune system disorders: anaphylactic reactions with hypotension, dyspnea, bronchospasm, urticaria, erythema

Warnings & Precautions

5 WARNINGS AND PRECAUTIONS Cardiovascular Reactions: Severe or life-threatening cardiovascular reactions including cardiac arrest, arrhythmia, asystole, atrioventricular block second degree, hypotension, elevation in blood pressure, bradycardia, and tachycardia have been reported. Closely monitor blood pressure and cardiac rhythm during and following the BLUDIGO injection. Interrupt administration if reactions are observed. ( 5.1 ) Hypersensitivity Reactions: Serious anaphylactic reactions with hypotension, dyspnea, bronchospasm, urticaria, or erythema have been reported. Monitor patients for anaphylactic reactions and have emergency equipment and trained personnel readily available. ( 5.2 ) Interference with Oximetry Measurements: Anesthesiologists should be aware of the potential for artifactual reduction in SpO 2 when anesthetized patients are administered BLUDIGO. ( 5.3 ) 5.1 Cardiovascular Reactions Severe or life-threatening cardiovascular reactions including cardiac arrest, arrhythmia, asystole, second degree atrioventricular block, hypotension, elevation in blood pressure, bradycardia, and tachycardia have been reported generally within 60 minutes following administration of indigotindisulfonate sodium injection products and required urgent intervention [see Adverse Reactions ( 6.2 )]. Indigotindisulfonate may cause vasoconstriction by interference with vasodilation mediated by nitric oxide dependent mechanisms and by direct vasoconstriction. Indigotindisulfonate may also cause hypotension. Patients with hypertension, heart rate and conduction disorders, or medications causing bradycardia may be at increased risk for elevated blood pressure, hypotension, and bradycardia. Closely monitor blood pressure and cardiac rhythm during and following the injection of BLUDIGO. Interrupt administration if reactions are observed. 5.2 Hypersensitivity Reactions Serious anaphylactic reactions with hypotension, dyspnea, bronchospasm, urticaria, or erythema have been reported with the use of indigotindisulfonate sodium injection products [see Adverse Reactions ( 6.2 )] . BLUDIGO is contraindicated in patients with known hypersensitivity to indigotindisulfonate [see Contraindications ( 4 )] . Monitor patients for anaphylactic reactions and have emergency equipment and trained personnel readily available. 5.3 Interference with Oximetry Measurements Indigotindisulfonate has been reported to interfere with light absorption and transiently interfere with pulse oximetric methods. Anesthesiologists should be aware of the potential for artifactual reduction in SpO 2 when anesthetized patients are administered BLUDIGO.
