FULL PRESCRIBING INFORMATION

SORBITOL DESCRIPTION

3% Sorbitol Urologic Irrigating Solution is a sterile, nonpyrogenic, nonhemolytic, electrically nonconductive solution in a single dose UROMATIC Plastic Container for use as a urologic irrigating solution. Each liter contains 30 g Sorbitol in Water for Injection. pH 5.0 (4.5 to 6.5). Osmolarity 165 mOsmol/L (calc.). No antimicrobial agent has been added.

Sorbitol is a reduced form of dextrose and is designated chemically as D-Glucitol,

The UROMATIC plastic container is fabricated from a specially formulated polyvinyl chloride (PL 146 plastic). The amount of water that can permeate from inside the container into the overwrap is insufficient to affect the solution significantly. Solutions in contact with the plastic container can leach out certain of its chemical components in very small amounts within the expiration period, e.g., di-2-ethylhexyl phthalate (DEHP), up to 5 parts per million; however, the safety of the plastic has been confirmed in tests in animals according to USP biological tests for plastic containers as well as by tissue culture toxicity studies.

CLINICAL PHARMACOLOGY

3% Sorbitol Urologic Irrigating Solution is useful as an irrigating fluid for the urinary bladder because the sorbitol solution is nonhemolytic, electrically nonconductive, and provides a high degree of visibility for urologic procedures requiring endoscopy. During transurethral surgical procedures, the solution acts as a lavage for removing blood and tissue fragments. It is also useful as an irrigating fluid to maintain the patency of an indwelling catheter in the immediate postoperative period. If absorbed either intravascularly or extravascularly during transurethral resections, the sorbitol will be either metabolized to carbon dioxide and water via the fructose pathway, or excreted by a normally functioning kidney.

SORBITOL INDICATIONS AND USAGE

3% Sorbitol Urologic Irrigating Solution is indicated for use as a urologic irrigating fluid with endoscopic instruments during transurethral procedures requiring distension, irrigation, and lavage of the urinary bladder. It may be used for lavage of an indwelling catheter to maintain patency.

SORBITOL CONTRAINDICATIONS

Anuria.

WARNINGS

Not for injection.

Not for use in patients with documented or suspected fructose intolerance.

Solutions for urologic irrigation must be used with caution in patients with severe cardiopulmonary or renal dysfunction.

Irrigating fluids used during transurethral prostatectomy have been demonstrated to enter the systemic circulation in relatively large volumes; thus sorbitol irrigating solution must be regarded as a systemic drug. Absorption of large amounts of fluids containing sorbitol may significantly alter cardiopulmonary and renal dynamics. Appropriate patient monitoring should be maintained due to the possibility of fluid overload. Should fluid overload occur, intensive fluid and electrolyte management is necessary. Monitoring of fluid and electrolyte levels beyond the acute phase may be considered due to the possibility of delayed fluid absorption. (See ADVERSE REACTIONS, Post-Marketing Experience)

Hyperglycemia from metabolism of absorbed sorbitol may occur in patients with diabetes mellitus.

The contents of an opened container should be used promptly to minimize the possibility of bacterial growth or pyrogen formation. Discard the unused portion of irrigating solution since no antimicrobial agent has been added.

PRECAUTIONS

The cardiovascular status, especially of the patient with cardiac disease, should be carefully observed before and during transurethral resection of the prostate when using 3% Sorbitol Urologic Irrigating Solution, because the quantity of fluid absorbed into the systemic circulation by opened prostatic veins may produce significant expansion of the intravascular fluid and lead to fulminating congestive heart failure.

Shift of sodium free intracellular fluid into the extracellular compartment, following systemic absorption may lower serum concentration and aggravate preexisting hyponatremia.

Excessive loss of water and electrolytes may lead to serious imbalances. With continuous administration of solution, loss of water may occur in excess of electrolytes, producing hypernatremia.

Sustained diuresis that results from transurethral irrigation with sorbitol irrigating solutions may obscure and intensify inadequate hydration or hypovolemia.

Pregnancy

Teratogenic Effects

Pregnancy category C.

Animal reproduction studies have not been conducted with 3% Sorbitol Urologic Irrigating Solution. It is not known whether 3% Sorbitol Urologic Irrigating Solution can cause fetal harm when administered to a pregnant woman or can affect reproductive capacity. 3% Sorbitol Urologic Irrigating Solution should be given to a pregnant woman only if clearly needed.

Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

Geriatric Use

Clinical studies of Irrigation Solutions did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from other younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients.

Do not administer unless the solution is clear and the seal is intact.

SORBITOL ADVERSE REACTIONS

Life threatening adverse reactions with intravenous sorbitol infusions have been reported in patients with fructose intolerance.

The literature reports occasional adverse reactions for intravenous sorbitol infusions. These include disturbances such as acidosis, electrolyte loss, marked diuresis, urinary retention, edema, dryness of mouth and thirst, and dehydration; cardiovascular/pulmonary disorders such as pulmonary congestion, hypotension, tachycardia, angina-like pains, and other general reactions such as blurred vision, convulsions, nausea, vomiting, diarrhea, rhinitis, chills, vertigo, and backache. Allergic reactions reported to occur from sorbitol include urticaria.

Should adverse reactions occur, discontinue the irrigant and reevaluate the clinical status of the patient.

Post-Marketing Experience

Following off-label use of 3% Sorbitol Urologic Irrigating Solution for hysteroscopic procedures in women, life-threatening adverse events related to fluid overload have been reported.

SORBITOL DOSAGE AND ADMINISTRATION

The volume of solution needed will vary with the nature and duration of the urologic procedure.

If desired, warm in overwrap to near body temperature in a water bath or oven heated to not more than 45°C.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

HOW SUPPLIED

3% Sorbitol Urologic Irrigating Solution in UROMATIC plastic containers is available as follows:

Exposure of pharmaceutical products to heat should be minimized. Avoid excessive heat. It is recommended the product be stored at room temperature (25°C); brief exposure up to 40°C does not adversely affect the product.

DIRECTIONS FOR USE

Tear overwrap down side at slit and remove solution container. Some opacity of the plastic due to moisture absorption during the sterilization process may be observed. This is normal and does not affect the solution quality or safety. The opacity will diminish gradually. Check for minute leaks by squeezing bag firmly. If leaks are found, discard solution as sterility may be impaired.

Use Aseptic Technique.

• Suspend container using hanger hole.
• Remove protector from outlet port.
• Attach irrigation set. Refer to complete directions accompanying set.
