Interaction Map: Interactions with other medicines and products — official regulatory information for Lipril 20

Interaction scope

Medicinal product categories with documented interactions: Neprilysin inhibitors, Dual RAS blockers, Potassium-sparing diuretics, NSAIDs, Other Antihypertensives, Antidiabetic Agents, and Lithium.

Specific interacting medicines (if explicitly listed): Sacubitril/Valsartan, Aliskiren, Spironolactone, Amiloride, Triamterene.

Mechanistic basis of interactions (only if stated in label): Pharmacodynamic effects (e.g., additive hyperkalaemia, excessive hypotension) and alteration of renal clearance (e.g., Lithium). Lisinopril is documented as not being metabolized by the Cytochrome P450 system.

Timing-based interaction rules (if applicable): Lisinopril must not be administered within 36 hours of initiating or stopping Sacubitril/Valsartan.

Population-specific interaction notes (if applicable): Co-administration of Aliskiren is contraindicated in patients with diabetes. The risk of renal function deterioration with NSAIDs is heightened in elderly or volume-depleted patients.

Interaction-related restrictions: Concomitant use with Neprilysin Inhibitors is prohibited. Concomitant use with potassium-sparing diuretics is generally not recommended.

---

Interaction classifications (high-level)

Interaction severity classification (as defined in official documents): Contraindicated (Sacubitril/Valsartan, Aliskiren in diabetes), Use Not Recommended (Potassium-sparing diuretics, Lithium).

Regulatory basis (EMA / FDA / etc.): FDA Prescribing Information, EMA Summary of Product Characteristics (SmPC).

Interaction-context constraints (as defined in official documents): Restrictions are imposed based on drug class, disease state (diabetes), and organ function status (renal impairment).

---

Resulting interaction structure

Official interaction statements:

• Contraindicated Combination: Co-administration with Sacubitril/Valsartan is strictly prohibited due to an increased risk of angioedema.
• Pharmacodynamic Risk: Concomitant use with potassium-sparing diuretics, supplements, or other potassium-increasing agents increases the documented risk of hyperkalaemia.
• Exposure Effect: Lisinopril reduces the renal clearance of Lithium, resulting in an officially documented increase in serum Lithium concentrations and potential toxicity.
• Food Interaction: Lisinopril's absorption is not influenced by the presence of food in the stomach.

Connection to the overall interaction profile (2–4 sentences):

The official profile is structured around prohibitions on Dual Renin-Angiotensin System blockade and managing pharmacodynamic risks like hyperkalaemia. Regulatory documents mandate specific timing rules for contraindicated combinations and formally list additive effects, while confirming the absence of CYP-mediated interaction pathways.

Lipril (Lisinopril) is an oral, nonsulfhydryl, long-acting angiotensin-converting enzyme (ACE) inhibitor that acts within the renin-angiotensin-aldosterone system (RAAS).

It functions as a competitive inhibitor of the ACE enzyme, which is a peptidyl dipeptidase found predominantly in the endothelium of blood vessels. This inhibition blocks the catalytic conversion of the decapeptide angiotensin I into the potent vasoconstrictor and aldosterone-releasing octapeptide, angiotensin II. The resulting decrease in systemic angiotensin II concentration leads to two primary downstream effects. First, it causes arteriolar relaxation and vasodilation, which decreases systemic vascular resistance. Second, it suppresses the adrenal cortex's secretion of the mineralocorticoid aldosterone. Reduced aldosterone activity decreases sodium and water reabsorption in the renal collecting ducts, resulting in natriuresis and diuresis, which ultimately decreases plasma volume. This system-level modulation of the RAAS pathway contributes to a sustained reduction in peripheral vascular resistance and circulating fluid volume.

Administration Guidelines

Lipril 20 (Lisinopril) is administered orally and is available as an oral tablet across multiple strengths, including 2.5 mg up to 40 mg. Standard regimens are designed for once-daily use. The medication can be taken with or without food, but administration should occur at approximately the same time each day to maintain consistent usage.

---

Dosing Regimens and Adjustment

Administration typically follows a titration approach, starting with a low initial dose which is then gradually increased to reach the appropriate maintenance dose for the condition, adhering to specified maximum daily limits, such as 80 mg for hypertension. For chronic conditions like hypertension, use is intended to be long-term. Following acute myocardial infarction, the stepped regimen includes a minimum duration of six weeks.

---

Population-Specific Use and Scheduling

Specific dosage modifications are defined for certain populations. The initial dose is reduced in adults who have impaired kidney function (creatinine clearance 30 mL/min or less). The initial dose is also lower when the patient is concurrently taking a diuretic. Pediatric use, for children age six and older, requires weight-based dosing. Should a dose be missed, it is typically recommended to skip the missed dose and resume the schedule at the next designated time, avoiding a double dose.

Research Evidence Overview

Lipril 20 contains lisinopril, an Angiotensin-Converting Enzyme (ACE) inhibitor. Research has consistently evaluated its use in managing hypertension (high blood pressure), congestive heart failure (CHF), and following acute myocardial infarction (heart attack) in clinically stable patients.

---

Clinical Trials in Hypertension and Heart Failure

Numerous studies confirm the compound's effect in reducing both systolic and diastolic blood pressure. In patients with mild to moderate essential hypertension, clinical trials utilizing a daily dose of 20 mg to 40 mg have demonstrated significant blood pressure reduction.

Research on lisinopril in congestive heart failure has shown that its use is associated with improvements in measures of heart function, including increased exercise tolerance and improved left ventricular ejection fraction. Studies comparing lisinopril to other ACE inhibitors in the elderly population with CHF found it to be similarly effective and well-tolerated.

---

Post-Myocardial Infarction Findings

Data from large-scale trials, such as the GISSI-3 study, evaluated the effect of lisinopril when initiated within 24 hours of an acute myocardial infarction. The findings indicated that lisinopril use was associated with a reduction in both overall mortality and the risk of developing left ventricular dysfunction when administered for up to six weeks.

Renal and Metabolic Research

Studies involving patients with diabetic nephropathy and hypertension have examined the effect of lisinopril on kidney health parameters. Results have included observed reductions or trends toward reductions in albuminuria, indicating an evaluation of its potential for renal protection in this population.
