Amtas LP Tablet

Uses of Amtas LP Tablet

Antihypertensive

Side Effects of Amtas LP Tablet

Nausea, headache, dizziness, cough, diarrhoea, fatigue, rash, oedema, flushing, palpitation, chest pain, asthenia, dry mouth; elevations in BUN, serum creatinine and potassium may occur. Potentially Fatal: Angioneurotic oedema reported with ACE inhibitors.

Drug Interactions

There is an increased risk of hypotension with concurrent use of antihypertensives with alprostadil. Amlodipine: Increased risk of hypotension with concurrent use with alprostadil, non-nucleoside reverse trancriptase inhibitors and cytochrome P450 inhibitors such as protease inhibitors (such as ritonovir), quinupristin/dalfopristin, azole antifungals (such as itraconazole and ketoconazole). Reduced effect of amlodipine with cytochrome P450 inducers such as phenobarbital, primidone, rifampicin and St John's Wort. Lisinopril: It reduces potassium loss caused by thiazides. Patients on diuretics may experience increased reduction in BP. Hyperkalaemia with concomitant use of potassium-sparing diuretics/potassium supplements may occur. Lisinopril may increase serum lithium levels; monitoring of serum lithium levels is recommended. Concurrent use with NSAIDs may further worsen renal function in patients with renal impairment; may also reduce the antihypertensive effect of lisinopril.

Contraindications

Hypersensitivity to either component, history of angioedema related to ACE inhibitor, patients with hereditary or idiopathic angioedema. Pregnancy & lactation.

Mechanism of Action

Amlodipine is a dihydropyridine calcium channel blocker that inhibits transmembrane influx of calcium ions into the vascular smooth muscle and cardiac muscle. Lisinopril is an angiotension-converting enzyme inhibitor that reduces BP, mainly by suppressing the renin-angiotensin-aldosterone system. Absorption: Amlodipine: Plasma levels peak between 6-12 hr after oral admin; absolute bioavailability is about 64-90%. Lisinopril: Serum levels peak at approx 7 hr after oral admin. Distribution: Amlodipine: Volume of distribution: 21L/kg; protein-binding: 93 to 98%. Lisinopril: Protein-binding: 25% Metabolism: Amlodipine: About 90% converted to inactive metabolites by the liver. Lisinopril: Does not undergo metabolism. Excretion: Amlodipine: 10% of the parent drug and 60% of the metabolites are removed in the urine; terminal elimination half-life of about 30-50 hr. Lisinopril: Excreted unchanged entirely in the urine; elimination half-life: 11-12 hr.
