🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionLisinopril is absorbed slowly and incompletely from the gastrointestinal tract, with an average bioavailability of about 25-30%. Food does not significantly affect absorption.
DistributionLisinopril distributes widely into body tissues, except it does not cross the blood-brain barrier to a significant extent. It crosses the placenta and is excreted in breast milk in small amounts.
Protein BindingLisinopril has very low protein binding (about 7%), primarily to albumin.
MetabolismLisinopril is not metabolized by the liver and is excreted unchanged in the urine.
Half-LifeThe elimination half-life is approximately 12 hours, but it is prolonged in patients with renal impairment.
ExcretionLisinopril is excreted primarily unchanged in the urine via glomerular filtration. About 70% of an absorbed dose is recovered in urine, and about 30% in feces.
BioavailabilityApproximately 25-30%
Onset of ActionBlood pressure reduction begins within 1 hour after oral administration, with peak effect in about 6 hours.
Peak Plasma TimePeak plasma concentration is reached in about 6-8 hours.
Duration of ActionThe antihypertensive effect lasts for about 24 hours, allowing once-daily dosing.

How It Works

This medicine works by blocking the angiotensin-converting enzyme (ACE). This enzyme converts angiotensin I to angiotensin II, a powerful substance that narrows blood vessels. By blocking ACE, this medicine reduces the production of angiotensin II, leading to relaxation of blood vessels and lower blood pressure. It also reduces the secretion of aldosterone, which helps lower sodium and water retention and reduces potassium loss. This results in decreased workload on the heart and improved kidney blood flow.

Mechanism Steps

1
ACE inhibition: This medicine binds to and inhibits the angiotensin-converting enzyme, preventing the conversion of angiotensin I to angiotensin II.
2
Reduced angiotensin II: Lower levels of angiotensin II lead to less vasoconstriction and reduced aldosterone release.
3
Vasodilation: Blood vessels relax and widen, lowering blood pressure and reducing the heart's workload.
4
Reduced aldosterone: Decreased aldosterone leads to increased sodium and water excretion, further lowering blood pressure and reducing potassium loss.
5
Cardiac and renal effects: The combined effects reduce preload and afterload, improve cardiac output in heart failure, and slow kidney damage in diabetic nephropathy.

💡 How to Take lisir 2.5mg tablet

Strength: 2.5 mg immediate-release tablet

1Take this medicine by mouth with or without food.
2Swallow the tablet whole with a glass of water.

Dosage Information

Adult DosageThe usual starting dose for hypertension is 10 mg once daily, but your doctor may start with 2.5 mg if you are also taking a diuretic or have heart failure. The dose may be increased gradually up to 40 mg daily. For heart failure, the starting dose is 2.5-5 mg once daily, increased as tolerated. After a heart attack, 5 mg is given within 24 hours, then 5 mg after 24 hours, and 10 mg once daily thereafter. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may be more sensitive to the blood pressure-lowering effects. Start with a lower dose (e.g., 2.5-5 mg) and monitor closely for dizziness and kidney function.
Renal ImpairmentIn patients with renal impairment, the initial dose should be reduced. For creatinine clearance 10-30 mL/min, start with 2.5-5 mg daily. For creatinine clearance less than 10 mL/min, start with 2.5 mg daily. Dose must be individualized by a qualified clinician.
Hepatic ImpairmentNo specific dose adjustment is required for hepatic impairment, but caution is advised. Monitor for adverse effects.
Maximum Daily Dose40 mg per day
