Qbrelis lisinopril 1 mg/mL Solution, 150 mL

5 WARNINGS AND PRECAUTIONS Angioedema: Discontinue QBRELIS; provide appropriate therapy and monitor until resolved ( 5.2 ). Renal impairment: Monitor renal function periodically ( 5.3 ). Hypotension: Patients with other heart or renal diseases have increased risk, monitor blood pressure after initiation ( 5.4 ).

Hyperkalemia: Monitor serum potassium periodically ( 5.5 ). Cholestatic jaundice and hepatic failure: Monitor for jaundice or signs of liver failure ( 5.6 ).

5.1Fetal Toxicity Use of drugs that act on the renin-angiotensin system during the second and third trimesters of pregnancy reduces fetal renal function and increases fetal and neonatal morbidity and death. Resulting oligohydramnios can be associated with fetal lung hypoplasia and skeletal deformations. Potential neonatal adverse effects include skull hypoplasia, anuria, hypotension, renal failure, and death.

When pregnancy is detected, discontinue QBRELIS as soon as possible [see Use in Specific Populations ( 8.1 )].

5.2Angioedema and Anaphylactoid Reactions Angioedema Head and Neck Angioedema Angioedema of the face, extremities, lips, tongue, glottis and/or larynx, including some fatal reactions, have occurred in patients treated with angiotensin converting enzyme inhibitors, including lisinopril, at any time during treatment. Patients with involvement of the tongue, glottis or larynx are likely to experience airway obstruction, especially those with a history of airway surgery. QBRELIS should be promptly discontinued and appropriate therapy and monitoring should be provided until complete and sustained resolution of signs and symptoms of angioedema has occurred.

Patients with a history of angioedema unrelated to ACE inhibitor therapy may be at increased risk of angioedema while receiving an ACE inhibitor [see Contraindications ( 4 )] . ACE inhibitors have been associated with a higher rate of angioedema in Black than in non-Black patients. Patients receiving coadministration of an ACE inhibitor and mTOR (mammalian target of rapamycin) inhibitor (e.g., temsirolimus, sirolimus, everolimus) therapy or a neprilysin inhibitor may be at increased risk for angioedema [see Drug Interactions ( 7.7 , 7.8 )] .

Intestinal Angioedema Intestinal angioedema has occurred in patients treated with ACE inhibitors. These patients presented with abdominal pain (with or without nausea or vomiting); in some cases there was no prior history of facial angioedema and C-1 esterase levels were normal. In some cases, the angioedema was diagnosed by procedures including abdominal CT scan or ultrasound, or at surgery, and symptoms resolved after stopping the ACE inhibitor.

Anaphylactoid Reactions Anaphylactoid Reactions During Desensitization Two patients undergoing desensitizing treatment with hymenoptera venom while receiving ACE inhibitors sustained life-threatening anaphylactoid reactions. Anaphylactoid Reactions During Dialysis Sudden and potentially life threatening anaphylactoid reactions have occurred in some patients dialyzed with high-flux membranes and treated concomitantly with an ACE inhibitor. In such patients, dialysis must be stopped immediately, and aggressive therapy for anaphylactoid reactions must be initiated.

Symptoms have not been relieved by antihistamines in these situations. In these patients, consideration should be given to using a different type of dialysis membrane or a different class of antihypertensive agent. Anaphylactoid reactions have also been reported in patients undergoing low-density lipoprotein apheresis with dextran sulfate absorption.

5.3Impaired Renal Function Monitor renal function periodically in patients treated with QBRELIS. Changes in renal function including acute renal failure can be caused by drugs that inhibit the renin-angiotensin system. Patients whose renal function may depend in part on the activity of the renin-angiotensin system (e.g., patients with renal artery stenosis, chronic kidney disease, severe congestive heart failure, po…

6 ADVERSE REACTIONS Common adverse reactions (events 2% greater than placebo) by use: Hypertension: headache, dizziness and cough ( 6.1 ). Heart Failure: hypotension and chest pain ( 6.1 ). Acute Myocardial Infarction: hypotension ( 6.1 ). To report SUSPECTED ADVERSE REACTIONS, contact Azurity Pharmaceuticals, Inc., at 1-800-461-7449 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice. Hypertension In clinical trials in patients with hypertension treated with lisinopril, 5.7% of patients on lisinopril discontinued with adverse reactions. The following adverse reactions (events 2% greater on lisinopril than on placebo) were observed with lisinopril alone: headache (by 3.8%), dizziness (by 3.5%), and cough (by 2.5%).

Heart Failure In patients with systolic heart failure treated with lisinopril for up to four years, 11% discontinued therapy with adverse reactions. In controlled studies in patients with heart failure, therapy was discontinued in 8.1% of patients treated with lisinopril for 12 weeks, compared to 7.7% of patients treated with placebo for 12 weeks. The following adverse reactions (events 2% greater on lisinopril than on placebo) were observed with lisinopril: hypotension (by 3.8%), and chest pain (by 2.1%).

In the two-dose ATLAS trial [see Clinical Studies ( 14.2 )] in heart failure patients, withdrawals due to adverse reactions were not different between the low and high dose groups, either in total number of discontinuation (17-18%) or in rare specific reactions (< 1%). The following adverse reactions, mostly related to ACE inhibition, were reported more commonly in the high dose group: Table 1. Dose-related Adverse Drug Reactions: ATLAS trial High Dose (n=1568) Low Dose (n=1596) Dizziness 19% 12% Hypotension 11% 7% Creatinine increased 10% 7% Hyperkalemia 6% 4% Syncope 7% 5% Acute Myocardial Infarction Patients treated with lisinopril had a higher incidence of hypotension (by 5.3%) and renal dysfunction (by 1.3%) compared with patients not taking lisinopril.

Other clinical adverse reactions occurring in 1% or higher of patients with hypertension or heart failure treated with lisinopril in controlled clinical trials and do not appear in other sections of labeling are listed below: Body as a whole: Fatigue, asthenia, orthostatic effects. Digestive: Pancreatitis, constipation, flatulence, dry mouth, diarrhea. Hematologic: Rare cases of bone marrow depression, hemolytic anemia, leukopenia/neutropenia and thrombocytopenia.

Endocrine: Diabetes mellitus, inappropriate antidiuretic hormone secretion. Metabolic: Gout. Skin: Urticaria, alopecia, photosensitivity, erythema, flushing, diaphoresis, cutaneous pseudolymphoma, toxic epidermal necrolysis, Stevens - Johnson syndrome, and pruritus.

Special Senses: Visual loss, diplopia, blurred vision, tinnitus, photophobia, taste disturbances, olfactory disturbance. Urogenital: Impotence. Miscellaneous: A symptom complex has been reported which may include a positive ANA, an elevated erythrocyte sedimentation rate, arthralgia/arthritis, myalgia, fever, vasculitis, eosinophilia, leukocytosis, paresthesia and vertigo.

Rash, photosensitivity or other dermatological manifestations may occur alone or in combination with these symptoms. Clinical Laboratory Test Findings Serum Potassium: In clinical trials hyperkalemia (serum potassium greater than 5.7 mEq/L) occurred in 2.2% and 4.8% of lisinopril-treated patients with hypertension and heart failure, respectively [see Warnings and Precautions ( 5.5 )] . Creatinine, Blood Urea Nitrogen: Minor increases in blood urea nitrogen and serum creatinine, reversible upon discontinuation of therapy, were observed in about 2% of patients with hypertension treat…

7 DRUG INTERACTIONS Diuretics: Excessive drop in blood pressure ( 7.1 ). NSAIDS: Increased risk of renal impairment and loss of antihypertensive efficacy ( 7.3 ). Dual inhibition of the renin-angiotensin system: Increased risk of renal impairment, hypotension and hyperkalemia ( 7.4 ). Lithium: Symptoms of lithium toxicity ( 7.5 ). Gold: Nitritoid reactions have been reported ( 7.6 ).

7.1Diuretics Initiation of QBRELIS in patients on diuretics may result in excessive reduction of blood pressure. The possibility of hypotensive effects with QBRELIS can be minimized by either decreasing or discontinuing the diuretic or increasing the salt intake prior to initiation of treatment with QBRELIS. If this is not possible, reduce the starting dose of QBRELIS [see Dosage and Administration ( 2.2 ) and Warnings and Precautions ( 5.4 )] .

QBRELIS attenuates potassium loss caused by thiazide-type diuretics. Potassium-sparing diuretics (spironolactone, amiloride, triamterene, and others) can increase the risk of hyperkalemia. Therefore, if concomitant use of such agents is indicated, monitor the patient’s serum potassium frequently.

7.2Antidiabetics Concomitant administration of QBRELIS and antidiabetic medicines (insulins, oral hypoglycemic agents) may cause an increased blood-glucose-lowering effect with risk of hypoglycemia.

7.3Non-Steroidal Anti-Inflammatory Agents Including Selective Cyclooxygenase-2 Inhibitors (COX-2 Inhibitors) In patients who are elderly, volume-depleted (including those on diuretic therapy), or with compromised renal function, co-administration of NSAIDs, including selective COX-2 inhibitors, with ACE inhibitors, including lisinopril, may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving lisinopril and NSAID therapy.

The antihypertensive effect of ACE inhibitors, including lisinopril, may be attenuated by NSAIDs.

7.4Dual Blockade of the Renin-Angiotensin System (RAS) Dual blockade of the RAS with angiotensin receptor blockers, ACE inhibitors, or aliskiren is associated with increased risks of hypotension, hyperkalemia, and changes in renal function (including acute renal failure) compared to monotherapy. The VA NEPHRON trial enrolled 1448 patients with type 2 diabetes, elevated urinary-albumin-to-creatinine ratio, and decreased estimated glomerular filtration rate (GFR 30 to 89.9 mL/min), randomized them to lisinopril or placebo on a background of losartan therapy and followed them for a median of 2.2 years.

Patients receiving the combination of losartan and lisinopril did not obtain any additional benefit compared to monotherapy for the combined endpoint of decline in GFR, end stage renal disease, or death, but experienced an increased incidence of hyperkalemia and acute kidney injury compared with the monotherapy group. In general, avoid combined use of RAS inhibitors. Closely monitor blood pressure, renal function and electrolytes in patients on QBRELIS and other agents that affect the RAS.

Do not co-administer aliskiren with QBRELIS in patients with diabetes. Avoid use of aliskiren with QBRELIS in patients with renal impairment (GFR < 60 mL/min).

7.5Lithium Lithium toxicity has been reported in patients receiving lithium concomitantly with drugs, which cause elimination of sodium, including ACE inhibitors. Lithium toxicity was usually reversible upon discontinuation of lithium and the ACE inhibitor. Monitor serum lithium levels during concurrent use.

7.6Gold Nitritoid reactions (symptoms include facial flushing, nausea, vomiting and hypotension) have been reported rarely in patients on therapy with injectable gold (sodium aurothiomalate) and concomitant ACE inhibitor therapy including lisinopril. 7.7 mTOR Inhibitors Patients taking concomitant mTOR inhibitor (e.g., temsirolimus, sirolimus, everolimus) therapy may be at increased risk for angioedema [see Warnings and Precautions (…
