Angeril Tablet

Angeril is an angiotensin converting enzyme (ACE) inhibitor, which after hydrolysis to ramiprilat, blocks the conversion of angiotensin I to the vasoconstrictor substance, angiotensin II. So, inhibition of ACE by ramipril results in decreased plasma angiotensin II, which leads to decreased vasopressor activity and decreased aldosterone secretion. Thus ramipril exerts its antihypertensive activity. It is also effective in the management of heart failure and reduction of the risk of stroke, myocardial infarction and death from cardiovascular events. It is long acting and well tolerated; so, can be used in long term therapy.

Uses

Angerilis used for the following cases:

  • Mild to severe hypertension
  • Congestive Heart failure.
  • To reduce the risk of stroke, myocardial infarction and death from cardiovascular events in patients with a history of cardiovascular disease.
  • Proteinuric non-diabetic nephropathy.

Angeril is also used to associated treatment for these conditions: Cardiovascular Events, Diabetic Nephropathy, Heart Failure, Heart Failure With Reduced Ejection Fraction (HFrEF), High Blood Pressure (Hypertension), Myocardial Infarction, Nondiabetic proteinuric chronic kidney disease, Stroke, High risk cardiovascular event

Dosage

Angeril dosage

Dosage of Angeril must be adjusted according to the patient tolerance and response.

Hypertension: For the management of hypertension in adults not receiving a diuretic, the usual initial dose of Angeril is 1.25 - 2.5 mg once daily. Dosage generally is adjusted no more rapidly than at 2 week intervals. The usual maintenance dosage in adults is 2.5 - 20 mg daily given as a single dose or in 2 divided doses daily. If BP is not controlled with Angeril alone, a diuretic may be added.

Congestive heart failure after myocardial infarction: In this case, Angeril therapy may be initiated as early as 2 days after myocardial infarction. An initial dose of 2.5 mg twice daily is recommended, but if hypotension occurs, dose should be reduced to 1.25 mg twice daily. Therapy is then titrated to a target daily dose of 5 mg twice daily. 

Prevention of major cardiovascular events: In this case, the recommended dose is 2.5 mg once daily for the first week of therapy and 5 mg once daily for the following 3 weeks; dosage then may be increased, as tolerated, to a maintenance dosage of 10 mg once daily.

Side Effects

Angeril is generally well tolerated. Dizziness, headache, fatigue and asthenia are commonly reported side effects. Other side effects occurring less frequently include symptomatic hypotension, cough, nausea, vomiting, diarrhoea, rash, urticaria, oliguria, anxiety, amnesia etc. Angioneurotic oedema, anaphylactic reactions and hyperkalaemia have also been reported rarely.

Precaution

Angeril should be used with caution in patients with impaired renal function, hyperkalaemia, hypotension, and impaired hepatic function.

Interaction

With Diuretics: Patients on diuretics, especially those in whom diuretic therapy was recently instituted, may occasionally experience an excessive reduction of blood pressure after initiation of therapy with ramipril.

With Potassium Supplements and Potassium-sparing Diuretics: Angeril can attenuate potassium loss caused by thiazide diuretics. Potassium-sparing diuretics (spironolactone, amiloride, triamterene, and others) or potassium supplements can increase the risk of hyperkalemia.

Other: Neither ramipril nor its metabolites have been found to interact with food, digoxin, antacid, furosemide, cimetidine, indomethacin, and simvastatin. The combination of ramipril and propranolol showed no adverse effects on dynamic parameters (blood pressure and heart rate). The co-administration of ramipril and warfarin did not adversely affect the anticoagulant effects of the latter drug.

Food Interaction

  • Avoid potassium-containing products. Potassium products increase the risk of hyperkalemia.
  • Take with or without food. The absorption is unaffected by food.

Half Life

Plasma concentrations of ramiprilat decline in a triphasic manner. Initial rapid decline represents distribution into tissues and has a half life of 2-4 hours. The half life of the apparent elimination phase is 9-18 hours, which is thought to represent clearance of free drug. The half-life of the terminal elimination phase is > 50 hours and thought to represent clearance of drug bound to ACE due to its slow dissociation. The half life of ramiprilat after multiple daily doses (MDDs) is dose-dependent, ranging from 13-17 hours with 5-10 mg MDDs to 27-36 hours for 2.5 mg MDDs.

Clearance

The renal clearance of ramipril and ramiprilat was reported to be 7.2 and 77.4 mL/min/1.73m2. The mean renal clearance of ramipril and ramiprilat is reported to be 10.7 and 126.8 mL/min in healthy elderly patients with normal renal function, additionally the Cmax of ramiprilat is approximately 20% higher in this population. While the pharmacokinetics of ramipril appear unaffected by reduced renal function, the plasma concentration and half-life of ramiprilat are increased. In patient's with hepatic failure the concentration of ramipril is initially increased while the tmax of ramiprilat is prolonged due to a reduced ability to metabolize the drug. However, steady state concentrations of ramiprilat are the same in hepatic failure as in healthy patients.

Pregnancy & Breastfeeding use

If pregnancy is detected, ramipril should be discontinued as early as possible unless continued use is considered life saving. Angeril should not be used during lactation.

Contraindication

It is contraindicated in patients who are hypersensitive to any component of this product and in patients with a history of angioedema related to previous treatment with a ACE inhibitor.

Special Warning

Dosage in renal impairment: For the patients with hypertension and renal impairment, the recommended initial dose is 1.25 mg Angeril once daily. Subsequent dosage should be titrated according to individual tolerance and BP response, up to a maximum of 5 mg daily. For the patients with heart failure and renal impairment, the recommended dose is 1.25 mg once daily. The dose may be increased to 1.25 mg twice daily and up to a maximum dose of 2.5 mg twice daily depending upon clinical response and tolerability. 

Use in children: No information is yet available on the use of Angeril in children.

Acute Overdose

Limited data on human overdosage are available. The most likely clinical manifestations would be symptoms attributable to hypotension. Because the hypotensive effect of Angeril is achieved through vasodilation and effective hypovolemia, it is reasonable to treat Angeril overdosage by infusion of normal saline solution.

Storage Condition

Store at cool & dry place, protect from light and moisture.
