Cysto-Conray II is a sterile aqueous solution intended for instillation as a diagnostic radiopaque medium. Cysto-Conray II contains 17.2% w/v iothalamate meglumine which is 1-Deoxy-1-(methylamino)-D-glucitol 5-acetamido-2,4,6-triiodo-N-methylisophthalamate (salt) and has the following structural formula:

Each milliliter of Cysto-Conray II contains 172 mg of iothalamate meglumine, equivalent to 81 mg (8.1% w/v) of organically bound iodine, 0.110 mg edetate calcium disodium as a stabilizer and 0.115 mg of monobasic sodium phosphate as a buffer.

Cysto-Conray II is hypertonic under conditions of use and is supplied in containers from which the air has been displaced by nitrogen. The pH of Cysto-Conray II is 6.6 to 7.6.

The most important characteristic of contrast media is the iodine content.  The relatively high atomic weight of iodine contributes sufficient radiodensity for radiographic contrast.

Following instillation by sterile catheter, Cysto-Conray II provides for visualization of the lower urinary tract. Clinical literature reports indicate that routinely less than 1 percent of a retrograde urographic radiopaque is absorbed systemically, however, as much as 12 percent absorption was observed with pyelorenal back flow and may produce iodine medicated thyrotropic effects described under PRECAUTIONS .

Cysto-Conray II is indicated for use in retrograde cystography and cystourethrography.

See WARNINGS concerning inadvertant intrathecal administration.

SEVERE ADVERSE EVENTS – INADVERTENT INTRATHECAL ADMINISTRATION: Serious adverse reactions have been reported due to the inadvertent intrathecal administration of iodinated contrast media that are not indicated for intrathecal use. These serious adverse reactions include: death, convulsions, cerebral hemorrhage, coma, paralysis, arachnoiditis, acute renal failure, cardiac arrest, seizures, rhabdomyolysis, hyperthermia, and brain edema. Special attention must be given to ensure that this drug product is not administered intrathecally.

Diagnostic procedures which involve the use of radiopaque diagnostic agents should be carried out under the direction of personnel with the prerequisite training and with a thorough knowledge of the particular procedure to be performed. Appropriate facilities should be available for coping with any complication of the procedure, as well as for emergency treatment of severe reactions to the contrast agent itself. After administration of the radiocontrast agent, competent personnel and emergency facilities should be available for at least 30 to 60 minutes since delayed reactions have occurred (see ADVERSE REACTIONS ).

The possibility of an idiosyncratic reaction in susceptible patients should always be considered (see ADVERSE REACTIONS ). The susceptible population includes patients with a history of a previous reaction to a contrast medium, patients with a known sensitivity to iodine per se and patients with a known clinical hypersensitivity: bronchial asthma, hay fever and food allergies.

A positive history of allergies or hypersensitivity does not arbitrarily contraindicate the use of a contrast agent where a diagnostic procedure is thought essential, but caution should be exercised (see ADVERSE REACTIONS ). Premedication with antihistamines or corticosteroids to avoid or minimize possible allergic reactions in such patients should be considered. Recent reports indicate that such pre-treatment does not prevent serious life-threatening reactions, but may reduce both their incidence and severity.

Since these procedures require instrumentation, special precautions should be observed in those patients known to have an acute urinary tract infection.

Filling of the bladder should be done at a steady rate, exercising caution to avoid excessive pressure. Sterile procedures should be employed in administration.

No long-term animal studies have been performed to evaluate carcinogenic potential, mutagenic potential or whether this drug affects fertility in males or females.

Category C. Animal reproduction studies have not been conducted with Cysto-Conray II. It is also not known whether this drug can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Cysto-Conray II should be used in pregnant women only if clearly needed.

Iothalamate salts are excreted unchanged in human milk. Although it has not been established that serious adverse reactions occur in nursing infants, because of the potential for adverse reactions, caution should be exercised when Cysto-Conray II is administered to a nursing woman.

Patients receiving diagnostic agents for instillation urography should be instructed to:

Thyroid Function Tests – If indicated, these tests generally should be performed prior to the administration of any iodinated agent. However, thyroid function can be evaluated after use of these agents by using T resin uptake or free thyroxine assays.

Irritation of the bladder or ureter, common to some degree to all contrast media administered for retrograde urographic procedures, may occasionally occur.

As with all contrast media, intravasation may lead to hypersensitivity reactions such as a sense of warmth, flushing, sneezing, sweating, chills, fever, urticaria, laryngeal edema, bronchospasm, hypertension, hypotension, cardiac arrhythmias and cardiac arrest.

Adverse reactions associated with procedural technique include injury to the urethra, bladder, ureter, and introduction of infection.

In the event of serious or anaphylactoid reactions, it should be kept in mind that the reactions known to occur with intravenous administration of radiopaque contrast materials are possible.

Unless contraindicated, an appropriate laxative is given the night before the examination.

The radiographic procedure normally employed for cystography and cystourethrography should be employed. A preliminary radiograph is recommended before the contrast agent is administered.

Sterile catherization is essential. Cysto-Conray II may be introduced by gravity flow using an appropriate venoclysis set or by syringe. Excessive pressure should be avoided with any method of administration.

Cystography and Cystourethrography – Either Conray 43 supplied at 43% w/v or Cysto-Conray II supplied at a 17.2% w/v concentration may be used for these procedures. The desired concentration will vary depending upon the patient’s size and age and also with the technique and equipment used. (SEE CONRAY 43 PACKAGE INSERT FOR SPECIFIC INFORMATION ABOUT THE USE OF THIS PRODUCT.) Sufficient volume of contrast medium is administered to adequately fill the urinary bladder. The volume of solution required will vary depending upon the individual patient. Adults usually require a volume in the range of 200 to 400 mL. Children require a volume in proportion to their body size. The usual dose ranges from 30 to 300 mL.

Store at 20° to 25°C (68° to 77°F) [see USP Controlled Room Temperature]. Exposing this product to very cold temperatures may result in crystallization of the salt. If this occurs, the containers should be brought to room temperature. Shake vigorously to assure complete dissolution of any crystals. The speed of dissolution may be increased by heating with circulating warm air. Before use, examine the product to assure that all solids are redissolved and that the container and closure have not been damaged.

This product is sensitive to light and must be protected from strong daylight or direct exposure to the sun.

As with all contrast media, the containers should be inspected prior to use to ensure that breakage or other damage has not occurred during shipping and handling. All containers should be inspected for closure integrity. Damaged containers should not be used.
