ZESTRIL

Adult Patients: Following oral administration of Zestril, peak serum concentrations of lisinopril occur within about 7 hours, although there was a trend to a small delay in time taken to reach peak serum concentrations in acute myocardial infarction patients. Food does not alter the bioavailability of Zestril. Declining serum concentrations exhibit a prolonged terminal phase, which does not contribute to drug accumulation. This terminal phase probably represents saturable binding to ACE and is n...

14.1 Hypertension Two dose-response studies utilizing a once-daily regimen were conducted in 438 mild to moderate hypertensive patients not on a diuretic. Blood pressure was measured 24 hours after dosing. An antihypertensive effect of Zestril was seen with 5 mg of Zestril in some patients. However, in both studies blood pressure reduction occurred sooner and was greater in patients treated with 10 mg, 20 mg or 80 mg of Zestril than patients treated with 5 mg of Zestril. In controlled clinical studies of patients with mild to moderate hypertension, patients were treated with Zestril 20 mg to 8...

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 Upsher-Smith Laboratories, LLC at 1-855-899-9180 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in ...

Zestril is contraindicated in combination with a neprilysin inhibitor (e.g., sacubitril). Do not administer Zestril within 36 hours of switching to or from sacubitril/valsartan, a neprilysin inhibitor [see Warnings and Precautions (5.2)] . Zestril is contraindicated in patients with: a history of angioedema or hypersensitivity related to previous treatment with an angiotensin converting enzyme in...

Angioedema: Discontinue Zestril, 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 ) 5.1 Fetal Toxicity Zestril can cause fetal harm when adminis...
