What Is Qbrelis?

Qbrelis is a prescription oral solution containing lisinopril, an angiotensin-converting enzyme (ACE) inhibitor. It is used to treat hypertension in adults and children aged six years and older, as an additional treatment for heart failure, and in certain patients after an acute heart attack. Qbrelis contains 1 mg of lisinopril per milliliter and offers a liquid alternative to lisinopril tablets. It relaxes blood vessels and reduces certain effects of the renin-angiotensin system. Qbrelis carries a boxed warning for fetal toxicity and should not be used during pregnancy.

How Does Qbrelis Work?

Qbrelis contains lisinopril, which inhibits angiotensin-converting enzyme and reduces the conversion of angiotensin I into angiotensin II. Angiotensin II normally constricts blood vessels and stimulates aldosterone production, influencing blood pressure and fluid balance. By reducing these actions, lisinopril relaxes blood vessels and helps lower blood pressure. It also reduces certain pressures and workload affecting the heart. ACE inhibition can increase bradykinin levels, which may contribute to dry cough and angioedema. Qbrelis controls the effects of cardiovascular conditions but does not permanently cure them.

What Conditions Does Qbrelis Treat?

Qbrelis is approved for hypertension in adults and pediatric patients aged six years and older. It is also approved as adjunctive treatment for heart failure and for treatment of hemodynamically stable patients following an acute myocardial infarction. Lowering elevated blood pressure reduces long-term cardiovascular risks. A clinician evaluates blood pressure, kidney function, potassium levels, and other medications before prescribing it. Qbrelis should not be used during pregnancy or in patients with a history of ACE inhibitor-associated angioedema. It is not intended for immediate treatment of a hypertensive emergency.

How Should Qbrelis Be Taken?

Qbrelis is taken orally, with dosing based on the indication, age, kidney function, and treatment response. Adults beginning hypertension treatment commonly receive 10 mg, equivalent to 10 mL of the 1 mg/mL solution, once daily. Patients taking diuretics may begin at 5 mg daily. Children aged six years and older generally start at 0.07 mg per kilogram once daily, up to an initial maximum of 5 mg, when kidney function meets the prescribing criteria. Heart failure and post-heart-attack regimens have separate starting doses. Measure each dose using a suitable oral dosing device rather than a household spoon.

What Are the Side Effects and Warnings of Qbrelis?

Common adverse effects include dizziness, headache, dry cough, and low blood pressure. Serious risks include angioedema, kidney impairment, elevated potassium levels, and significant hypotension. Qbrelis carries a boxed warning for fetal toxicity because medications acting on the renin-angiotensin system can cause serious injury or death to a developing fetus. Patients with a history of ACE inhibitor-related angioedema should not take it. Combining lisinopril with certain potassium supplements or other medications can increase the risk of hyperkalemia. Facial or tongue swelling, breathing difficulty, fainting, or markedly reduced urination requires urgent medical assessment.

Common Questions About Qbrelis

Is Qbrelis the same as lisinopril?

Yes. Qbrelis contains lisinopril in a 1 mg/mL oral solution. Lisinopril tablets contain the same active ingredient but have a different dosage form.

Can children take Qbrelis?

Yes. Qbrelis is approved to treat hypertension in children aged six years and older, with weight-based dosing and kidney function requirements.

Can Qbrelis cause a dry cough?

Yes. Lisinopril and other ACE inhibitors can cause a persistent dry cough. Patients should discuss troublesome symptoms with their clinician.

Is Qbrelis safe during pregnancy?

No. Qbrelis carries a boxed warning for fetal toxicity. Patients who become pregnant should contact their healthcare professional immediately so treatment can be discontinued and replaced appropriately.
