Perindopril is an ACE inhibitor. It works by blocking the action of angiotensin converting enzyme (ACE). ACE produces angiotensin II, as part of the body's natural control of blood pressure. Angiotensin II causes blood vessels to constrict and narrow, which increases the pressure within the blood vessels. Perindopril blocks the action of ACE, it reduces the production of angiotensin II, thus allows the blood vessels to relax and widen. The overall effect of this is a drop in blood pressure.

Uses

Essential hypertension: Amlodipine is efficacious as monotherapy in the treatment of hypertension. It may be used in combination with other antihypertensive agents.Angina pectoris: Amlodipine is indicated for the treatment of chronic stable angina pectoris ... Read more

Perindopril is a long-acting ACE (Angiotensin Converting Enzyme) inhibitor and is used for-

Essential hypertension,
Stable coronary artery disease,
Congestive heart failure.

Dosage

Reaptan dosage

Hypertension: Usual dose is 5 mg once daily. The maximum dose is 10 mg once daily. Elderly patients with hepatic insufficiency may be started on 2.5 mg once daily; this dose may also be used when adding Amlodipine to other antihypertensive therapy.Angina (Chronic stable or Vasospastic): 5 to 10 mg, using the lower dose for elderly and in patients with hepatic insufficiency. Most patients require 10 mg.Administrations: May be taken without regard to meals.

Hypertension: One Perindopril 4 tablet once daily preferably in the morning. If necessary, the dose may be increased to 8 mg after 1 month of treatment. Perindopril should be taken before food.

Stable coronary artery disease: Perindopril 4 once daily for two weeks, then increased to 8 mg once daily, depending on renal function and provided that the 4 mg dose is well tolerated. Elderly patients should receive Perindopril 2 mg once daily for one week, then Perindopril 4 once daily the next week, before increasing the dose up to 8 mg once daily, depending on renal, function. The dose should be increased only if the previous lower dose is well tolerated.

Congestive heart failure: Perindopril should be started under close medical supervision at a starting dose of 2 mg in the morning. If necessary dose may be increased to 4 mg.

Elderly patients: Start at low daily dose (4 mg or less) and titrate slowly as needed. Experience with doses exceeding 8 mg is limited.

Side Effects

The most common adverse effects of amlodipine are associated with vasodilatory action, such as dizziness, flushing, headache, hypotension and peripheral edema. Gastrointestinal disturbances, increased micturition frequency, lethargy, eye pain and mental depression may also occur. A paradoxical increase in ischaemic chest pain may occur at the start of the treatment and in a few patients excessive fall in blood pressure has led to cerebral or myocardial ischaemia or transient blindness. Rashes, fever and abnormalities in liver function due to hypersensitivity reaction of Amlodipine may occur.

Rare and mild: usually at the start of treatment cough, fatigue, asthenia, headache, disturbances of mood and/or sleep have been reported.

Less often: Taste impairment, epigastric discomfort, nausea, abdominal pain and rash. Reversible increase in blood urea and creatinine may be observed. Proteinuria has occurred in some patients.

Rarely: Angioneurotic edema and decrease in hemoglobin, red cells and platelets have been reported.

Precaution

Precaution should be taken in patients with hepatic impairment and during pregnancy and breast feeding.

In the following cases, Perindopril should be used with caution:

Renovascular hypertension
Surgery/Anesthesia
Renal failure: The dose should be cautiously adjusted in accordance with the creatinine clearance
Symptomatic hypotension is rarely seen, but is more likely in volume-depleted patients, those receiving diuretics, or with the first two doses
In diuretic-treated patients: stop the diuretic 3 days before starting Perindopril. A diuretic may later be given in combination if necessary; potassium-sparing diuretics are not recommended
Combination with neuroleptics or imipramine-type drugs may increase the hypotensive effect. Serum lithium concentrations may rise during lithium therapy

Interaction

Drug Interactions- Potentially hazardous interactions: Little or no data are available in patients with markedly impaired cardiac left ventricular function; however, as with other calcium antagonist drugs, the combination of Amlodipine and p-blockers should be avoided in such patients. Other Significant Interactions- Digoxin: Absence of any interaction between Amlodipine and Digoxin in healthy volunteers has been documented in a controlled clinical study. Cimetidine: An unpublished clinical study indicated no interaction between, Amlodipine and Cimetidine in healthy volunteers. Warfarin: An unpublished clinical study in healthy volunteers indicates that Amlodipine did not significantly alter the effect of Warfarin on prothrombin time. Food: Food does not alter the rate or extent of absorption of Amlodipine.

May enhance hypotensive effect with diuretics. Additive hyperkalaemic effect with K supplements, K-sparing diuretics, and other drugs (e.g. ciclosporin, heparin, indometacin). May increase serum levels and toxicity of lithium. Antihypertensive effect may be reduced by aspirin or other NSAIDs. Coadministration with NSAIDs may also increase the risk of renal impairment. Increased risk of hypoglycaemia with antidiabetic agents. Rarely, nitritoid reactions occur with concomitant use of gold (Na aurothiomalate).

Pregnancy & Breastfeeding use

Pregnancy Category C. There are no adequate and well-controlled studies of Amlodipine in pregnant women. Amlodipine should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. It is not known whether Amlodipine is excreted in human milk. In the absence of this information, it is recommended that nursing be discontinued while Amlodipine is administered.

Perindopril should not be used during pregnancy & lactation.

Contraindication

Hypersensitivity to dihydropyridine derivatives. Pregnant woman.

Perindopril is contraindicated in patients with a history of hypersensitivity to Perindopril. This drug is contraindicated in case of management of hypertension of Children, during Pregnancy & Lactation.

Special Warning

Children with hypertension from 6 years to 17 years of age: 2.5 mg once daily as a starting dose, up-titrated to 5 mg once daily if blood pressure goal is not achieved after 4 weeks. Doses in excess of 5 mg daily have not been studied in pediatric patients.Children under 6 years old: The effect of amlodipine on blood pressure in patients less than 6 years of age is not known.Elderly: Amlodipine used at similar doses in elderly or younger patients is equally well tolerated. Normal dosage regimens are recommended in the elderly, but increase of the dosage should take place with care.Renal impairment: Changes in amlodipine plasma concentrations are not correlated with degree of renal impairment, therefore the normal dosage is recommended. Amlodipine is not dialysable.Hepatic impairment: Dosage recommendations have not been established in patients with mild to moderate hepatic impairment; therefore dose selection should be cautions and should start at the lower end of the dosing range. The pharmacokinetics of Amlodipine have not been studied in severe hepatic impairment. Amlodipine should be initiated at the lowest dose (2.5 mg once daily) and titrated slowly in patients with severe hepatic impairment.

Acute Overdose

Symptoms: Available data suggest that large overdosage could result in excessive peripheral vasodilatation and possibly reflex tachycardia. Marked and probably prolonged systemic hypotension up to and including shock with fatal outcome have been reported.Management: Clinically significant hypotension due to amlodipine overdosage calls for active cardiovascular support including frequent monitoring of cardiac and respiratory function, elevation of extremities, and attention to circulating fluid volume and urine output. A vasoconstrictor may be helpful in restoring vascular tone and blood pressure, provided that there is no contraindication to its use. Intravenous calcium gluconate may be beneficial in reversing the effects of calcium channel blockade. Gastric lavage may be worthwhile in some cases. In healthy volunteers the use of charcoal up to 2 hours after administration of amlodipine 10 mg has been shown to reduce the absorption rate of amlodipine. Since amlodipine is highly protein-bound, dialysis is not likely to be of benefit.
