What is Octafluoropropane?

Octafluoropropane lipid microsphere preparation is an ultrasound contrast agent. Ultrasound contrast agents are used to help provide a clear picture during ultrasound. Ultrasound is a special kind of diagnostic procedure. It uses high-frequency sound waves to create images or “pictures” of certain areas inside the body. The sound waves produced by the ultrasound equipment can be reflected (bounced off) by different parts of the body, like for example, the heart. As the sound waves return they are electronically converted into images on a television screen. Unlike x-rays, ultrasound does not involve ionizing radiation.

The Octafluoropropane lipid microspheres preparation contains very small gas-filled lipid microspheres that reflect the sound waves and help create a better picture. The lipid microsphere preparation is given by injection into a vein before ultrasound to help diagnose problems of the heart.

Octafluoropropane lipid microsphere is to be given only by or under the direct supervision of a doctor with specialized training in ultrasound procedures.

Octafluoropropane indications

Octafluoropropane is indicated for use in patients with suboptimal echocardiograms to opacify the left ventricle and to improve the delineation of the left ventricular endocardial borders.

DOSAGE AND ADMINISTRATION

Recommended Dosage

• The recommended dose of Octafluoropropane is 0.5 mL injected into a peripheral vein.
• If the contrast enhancement is inadequate after the dose of 0.5 mL, additional doses in increments of 0.5 mL may be repeated for further contrast enhancement as needed.
• The maximum total dose should not exceed 5mL in any 10 minute period.
• The maximum total dose should not exceed 8.7 mL in any one patient study.

Preparation Instructions

• Do not use if the container has been damaged, the protective seal and/or rubber cap have been entered, or the upper white layer is absent (may indicate the microspheres have been damaged and may result in poor or no echo contrast).
• Invert the Octafluoropropane vial and gently rotate to resuspend the microspheres. This process will allow the product to come to room temperature before use.
• Inspect the vial for complete resuspension. Do not use if the solution appears to be clear rather than opaque and milky-white.
• Vent the Octafluoropropane vial with a sterile vent spike or with a sterile 18 gauge needle before withdrawing the Octafluoropropane suspension into the injection syringe.
• Do not inject air into the vial.
• Use the product within one minute of suspension. If one minute is exceeded, resuspend by inverting and gently rotating the microsoheres in the syringe. Failure to adequately resuspend Octafluoropropane may cause inadequate delivery of the microspheres, and may result in inadequate contrast.

Administration Instructions

• Inspect visually for particulate matter and discoloration prior to administration, whenever solution and container permit. Do not inject if the solution is not opaque, milky-white, and absent particulate matter.
• Inject through a 20-gauge or larger angiocatheter into a peripheral vein at a rate not exceeding 1 mL per second. Suggested methods of administration include: a short extension tubing, heparin lock, or intravenous line, all with a 3-way stopcock.
• Administer intravenously; do not administer Octafluoropropane by intra-arterial injection.
• Do not aspirate blood back into the Octafluoropropane containing syringe before administration; this may promote the formation of a blood clot within the syringe.
• For short extension tubing or heparin lock: fill one syringe with 0.9% Sodium Chloride Injection, USP, and FLUSH the line for patency before and after the injection of Octafluoropropane.
• For a continuous intravenous line: open an intravenous line with 0.9% Sodium Chloride Injection, USP (or 5% Dextrose Injection, USP) at a slow infusion rate to maintain vascular patency. Flush the line immediately after injection of Octafluoropropane
• Do not use the single-patient use vial for more than one patient. Discard unused product.

How should I use Octafluoropropane?

Use Octafluoropropane (protein-type a microspheres) as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Octafluoropropane (protein-type a microspheres) will be given as an injection at your doctor's office, hospital, or clinic.
• Keep this product, as well as syringes and needles, out of the reach of children and away from pets. Do not reuse needles, syringes, or other materials. Ask your health care provider how to dispose of these materials after use. Follow all local rules for disposal.
• If you miss a dose of Octafluoropropane (protein-type a microspheres), contact your doctor right away.

Ask your health care provider any questions you may have about how to use Octafluoropropane (protein-type a microspheres).

Uses of Octafluoropropane in details

Use: Labeled Indications

Cardiovascular imaging: Opacification of the left ventricular chamber and improvement of delineation of the left ventricular endocardial border in patients with suboptimal echocardiograms

Off Label Uses

Focal liver lesion evaluation

Data from several observational studies support the use of Octafluoropropane lipid microspheres in the evaluation of focal liver lesions. Additional trials may be necessary to further define the role of Octafluoropropane lipid microspheres in this setting.

The World Federation for Ultrasound in Medicine and Biology guidelines and good clinical practice recommendations for contrast enhanced ultrasound (CEUS) in the liver provides general advice on the use of ultrasound contrast agents (eg, Octafluoropropane lipid microspheres) when evaluating focal liver lesions.

Octafluoropropane description

Octafluoropropane, a diagnostic drug that is intended to be used for contrast enhancement during the indicated echocardiographic procedures, is comprised of lipid-coated microspheres filled with octafluoropropane(OFP) gas. When exposed to ultrasound waves, the microspheres resonate and "echo" strong signals back to the ultrasound machine. The difference in density between the gas-filled bubbles and the blood around them creates an increased level of contrast visible in the resulting ultrasound image. During echocardiography, activated Octafluoropropane enhances images of the inner edges or borders of the heart, producing an improved image that may enable physicians to better diagnose patients.

Octafluoropropane dosage

Octafluoropropane Dosage

Generic name: Octafluoropropane

Dosage form: injectable suspension

The information at Drugs.com is not a substitute for medical advice. Always consult your doctor or pharmacist.

Octafluoropropane® IS INTENDED FOR ADMINISTRATION ONLY AFTER ACTIVATION IN THE VIALMIX® APPARATUS. Before injection, this product must be activated and prepared according to the instructions outlined below. The Vialmix® apparatus should be ordered from Bristol-Myers Squibb Medical Imaging, 331 Treble Cove Road, North Billerica, MA 01862. For customer orders call 1-800-299-3431.

Octafluoropropane® may be injected by either an intravenous bolus or infusion.

Bolus: The recommended dose for activated Octafluoropropane® is 10 microliters (µL)/kg of the activated product by intravenous bolus injection within 30-60 seconds, followed by a 10 mL saline flush. If necessary, a second 10 microliters (µL)/kg dose followed by a second 10 mL saline flush may be administered 30 minutes after the first injection to prolong contrast enhancement.

Infusion: The recommended dose for activated Octafluoropropane® is via an IV infusion of 1.3 mL added to 50 mL of preservative-free saline. The rate of infusion should be initiated at 4.0 mL/minute, but titrated as necessary to achieve optimal image enhancement, not to exceed 10 mL/minute.

The maximum dose is either two bolus doses or one single intravenous infusion. The safety of bolus and infusion dosing in combination or in sequence, has not been studied.

Imaging: After baseline non-contrast echocardiography is completed, the mechanical index for the ultrasound device should be set at 0.8 or below. Then inject activated Octafluoropropane® (as described above) and begin ultrasound imaging immediately. The activated Octafluoropropane® echocardiogram images should be evaluated in combination with the non-contrast echocardiogram images.

Octafluoropropane® ACTIVATION, PREPARATION AND HANDLING INSTRUCTIONS:

1. Allow the vial to warm to room temperature before starting the activation procedure.
