Lexiscan 0.4mg/5ml – Uses, Safety and Important Information

Lexiscan 0.4mg/5ml is a prescription injection containing the active ingredient regadenoson. Healthcare professionals use it as a pharmacologic stress agent for radionuclide myocardial perfusion imaging (MPI). For example, doctors might use it when a patient doesn’t have enough stamina to perform a standard exercise cardiac stress test.

What Is Lexiscan 0.4mg/5ml?

Lexiscan 0.4mg/5ml contains 0.4 mg regadenoson in 5 ml solution (0.08 mg/ml) It comes in a single-dose prefilled syringe. Hence, this medicine should not be considered as a common medicine for home use by patients. It is administered by a qualified healthcare professional in a controlled medical environment.

What is Lexiscan used to do?

Lexiscan assists physicians in radionuclide myocardial perfusion imaging. In this test, the drug temporarily increases blood flow through the coronary arteries. This effect is useful to health care professionals in assessing blood flow to the heart muscle during cardiac imaging.

Lexiscan also can be a pharmacological alternative for those who cannot achieve adequate exercise during a stress test.

How is Lexiscan given?

The prescribing information recommends an IV injection of 5 mL of Lexiscan (0.4 mg of regadenoson). The injection is given over approximately 10 seconds, followed by flushing with saline and then the appropriate radionuclide imaging agent.

Lexiscan should be given only by trained health care professionals. The patient should adhere to the preparation instructions provided by the medical team.

Caffeine and Lexiscan

Patients may be instructed to refrain from caffeine and other methylxanthine-containing products before a planned myocardial perfusion imaging procedure. The prescribing information advises that these products should be avoided for at least 12 hours before the procedure, as they can interfere with the pharmacologic effects of regadenoson.

So, you’ll want to ask your healthcare provider about any foods, drinks and medicines to avoid before you’re tested.

Important Safety Information

Lexiscan can cause serious heart reactions. Reported risks include myocardial ischaemia, heart block, bradycardia, ventricular arrhythmias, cardiac arrest and other cardiovascular complications. Thus, the healthcare professional should have adequate monitoring and emergency equipment available when the medicine is administered.

LEXISCAN is contraindicated in patients with second- or third-degree atrioventricular (AV) block or sick sinus syndrome, unless they have a functioning artificial pacemaker.

Also, allergic reactions can occur. Hypersensitivity reactions including rash, hives, angioedema, breathing problems and rarely severe reactions including anaphylaxis have been reported.

Typical Effects While Testing

Lexiscan can cause temporary effects on the heart and blood vessels and patients may experience symptoms such as shortness of breath, chest discomfort, headache, flushing, dizziness, nausea or a feeling of warmth. Any unusual or severe symptoms should be reported to the healthcare team immediately.

Conclusion

Lexiscan 0.4mg/5ml is an important diagnostic medicine used in radionuclide myocardial perfusion imaging when proper exercise stress is not possible. But it needs professional management and proper oversight. That’s why patients should only take Lexiscan under the direction of a qualified healthcare provider and should carefully follow all preparation instructions.
