For oral use.

Adults

Hypertension

Monotherapy: The recommended initial dosage is 10 mg once daily in uncomplicated hypertension. Depending upon clinical response, patient's dosage may be titrated (by doubling the dose allowing adequate time for dosage adjustment) to a maintenance dosage of 20 to 40 mg/day given as a single dose or divided into 2 doses. Long-term control is maintained in most patients with a single daily dosage regimen. Patients have been treated with dosages up to 80 mg/day.

Concomitant Diuretics: In order to determine if excess hypotension will occur, an initial dosage of 2.5 mg of Acupril Tablets is recommended in patients who are being treated with a diuretic. After this the dosage of Acupril Tablets should be titrated (as described above) to the optimal response.

Congestive Heart Failure

In order to closely monitor patients for symptomatic hypotension, a single 2.5 mg initial dosage is recommended. After this, patients should be titrated to an effective dose: (up to 40 mg/day) given in 1 or 2 doses with concomitant diuretic and/or cardiac glycoside therapy. Patients are usually maintained effectively on doses of 10-20 mg/day given with concomitant therapy. Take either with or without food. The dose should always be taken at about the same time of day to help increase compliance.

Severe Heart Failure

In the treatment of severe or unstable congestive heart failure, Acupril Tablets should always be initiated in hospital under close medical supervision.

Other patients who may also be considered to be at higher risk and should have treatment initiated in hospital include: patients who are on high dose loop diuretics (e.g.> 80 mg frusemide) or on multiple diuretic therapy, have hypovolaemia, hyponatraemia (serum sodium < 130 mmol/l) or systolic blood pressure < 90 mm Hg, are on high dose vasodilator therapy, have a serum creatinine > 150 µmol/l or are aged 70 years or over.

Take either with or without food. The dose should always be taken at about the same time of day to help increase compliance.

Elderly/Renal Impairment (over 65 years of age)

In elderly patients and in patients with a creatinine clearance of less than 40 ml/min, an initial dosage in essential hypertension of 2.5 mg is recommended followed by titration to the optimal response.

Paediatric population

<2 but no recommendation on a posology can be made.

Dual blockade of the renin-angiotensin-aldosterone system (RAAS)

There is evidence that the concomitant use of ACE-inhibitors, angiotensin II receptor blockers or aliskiren increases the risk of hypotension, hyperkalaemia and decreased renal function (including acute renal failure). Dual blockade of RAAS through the combined use of ACE-inhibitors, angiotensin II receptor blockers or aliskiren is therefore not recommended.

If dual blockade therapy is considered absolutely necessary, this should only occur under specialist supervision and subject to frequent close monitoring of renal function, electrolytes and blood pressure.

ACE-inhibitors and angiotensin II receptor blockers should not be used concomitantly in patients with diabetic nephropathy.

Acupril Tablets should be used with caution in selected patients with aortic stenosis or outflow obstruction.

Sensitivity reactions:

Sensitivity reactions may occur in patients with or without a history of allergy or bronchial asthma, e.g., purpura, photosensitivity, urticaria, necrotising angiitis, respiratory distress including pneumonitis and pulmonary oedema, anaphylactic reactions.

Symptomatic hypotension:

Symptomatic hypotension is seen rarely in uncomplicated hypertensive patients but it is a possible consequence of ACE inhibition. In hypertensive patients receiving Acupril, hypotension is more likely to occur if the patient has been salt/volume-depleted e.g., by diuretic therapy, dietary salt restriction, dialysis, diarrhoea or vomiting, or has severe renin-dependent hypertension.

If symptomatic hypotension occurs, the patient should be placed in the supine position and, if necessary, receive an intravenous infusion of normal saline. A transient hypotensive response is not a contraindication to further doses; however, lower doses of Acupril or any concomitant diuretic therapy should be considered if this event occurs.

In patients with congestive heart failure, who are at risk of excessive hypotension, Acupril therapy should be started at the recommended dose under close medical supervision; these patients should be followed closely for the first two weeks of treatment and whenever the dosage of Acupril is increased.

Similar considerations apply to patients with ischaemic heart or cerebrovascular disease in whom an excessive fall in blood pressure could result in a myocardial infarction or cerebrovascular accident.

Impaired Renal Function

In patients with renal insufficiency, monitoring of renal function during therapy should be performed as deemed appropriate; although in the majority renal function will not alter or may improve.

The half-life of Acuprilat is prolonged as creatinine clearance falls. Patients with a creatinine clearance of <40 ml/min require a lower initial dosage of Acupril. These patients' dosage should be titrated upwards based upon therapeutic response, and renal function should be closely monitored although initial studies do not indicate that Acupril produces further deterioration in renal function.

As a consequence of inhibiting the renin-angiotensin-aldosterone system, changes in renal function may be anticipated in susceptible individuals. In patients with severe heart failure whose renal function may depend on the activity of the renin-angiotensin-aldosterone system, treatment with ACE inhibitors including Acupril, may be associated with oliguria and/or progressive azotemia and rarely acute renal failure and/or death.

In clinical studies in hypertensive patients with unilateral or bilateral renal artery stenosis, increases in blood urea nitrogen and serum creatinine have been observed in some patients following ACE inhibitor therapy. These increases were almost always reversible upon discontinuation of the ACE inhibitor and/or diuretic therapy. In such patients, renal function should be monitored during the first few weeks of therapy.

Some patients with hypertension or heart failure with no apparent pre-existing renal vascular disease have developed increases >1.25 times the upper limit of normal) in blood urea and serum creatinine, usually minor and transient, especially when Acupril has been given concomitantly with a diuretic. Increases in blood urea nitrogen and serum creatinine have been observed in 2% and 2%, respectively of hypertensive patients on Acupril monotherapy and in 4% and 3%, respectively of hypertensive patients on Acupril/HCTZ. These increases are more likely to occur in patients with pre-existing renal impairment. Dosage reduction and/or discontinuation of a diuretic and/or Acupril may be required.

There is insufficient experience in patients with severe renal impairment (creatinine clearance <10 ml/min). Treatment is therefore not recommended in these patients.

Angioedema:

Angioedema has been reported in patients treated with angiotensin-converting enzyme inhibitors. If laryngeal stridor or angioedema of the face, tongue, or glottis occur, treatment should be discontinued immediately, the patient treated appropriately in accordance with accepted medical care, and carefully observed until the swelling disappears. In instances where swelling is confined to the face and lips, the condition generally resolves without treatment; antihistamines may be useful in relieving symptoms. Angioedema associated with laryngeal involvement may be fatal. Where there is involvement of the tongue, glottis, or larynx likely to cause airway obstruction, appropriate therapy e.g., subcutaneous adrenaline solution 1:1000 (0.3 to 0.5 ml) should be promptly administered.

Patients with a history of angioedema unrelated to ACE inhibitor therapy may be at increased risk of angioedema while receiving an ACE inhibitor.

Intestinal angioedema:

Intestinal angioedema has been reported in patients treated with ACE inhibitors. These patients presented with abdominal pain (with or without nausea or vomiting); in some cases there was no prior history of facial angioedema and C-1 esterase levels were normal. The angioedema was diagnosed by procedures including abdominal CT scan or ultrasound, or at surgery, and symptoms resolved after stopping the ACE inhibitor. Intestinal angioedema should be included in the differential diagnosis of patients on ACE inhibitors presenting with abdominal pain.

Ethnic Differences

Black patients receiving ACE inhibitor therapy generally have a higher incidence of angioedema than non-black patients. It should also be noted that in controlled clinical trials, ACE inhibitors have an effect on blood pressure that is less in black patients than in non-blacks.

Neutropenia/agranulocytosis:

ACE inhibitors have been rarely associated with agranulocytosis and bone marrow depression in patients with uncomplicated hypertension but more frequently in patients with renal impairment, especially if they also have collagen vascular disease. As with other ACE inhibitors, monitoring of white blood cell counts in patients with collagen vascular disease and/or renal diseases should be considered.

Agranulocytosis has been rarely reported during treatment with Acupril. Monitoring of white blood cell counts in patients with collagen vascular disease and/or renal disease should be considered.

Desensitization:

Patients receiving ACE inhibitors during desensitising treatment with hymenoptera venom have sustained life threatening anaphylactoid reactions. In the same patients, these reactions have been avoided when ACE inhibitors were temporarily withheld, but they have reappeared upon inadvertent re-challenge.

Haemodialysis and LDL Apheresis:

Patients haemodialysed using high-flux polyacrylonitrile ('AN69') membranes are highly likely to experience anaphylactoid reactions if they are treated with ACE inhibitors. This combination should therefore be avoided, either by use of alternative antihypertensive drugs or alternative membranes for haemodialysis. Similar reactions have been observed during low-density lipoprotein apheresis with dextran-sulphate. This method should therefore not be used in patients treated with ACE inhibitors.

Impaired Hepatic Function:

Acupril when combined with a diuretic should be used with caution in patients with impaired hepatic function or progressive liver disease, since minor alterations of fluid and electrolyte balance may precipitate hepatic coma. The metabolism of Acupril to Acuprilat is normally dependent upon hepatic esterase. Acuprilat concentrations are reduced in patients with alcoholic cirrhosis due to impaired de-esterification of Acupril.

Rarely, ACE inhibitors have been associated with a syndrome beginning as a cholestatic jaundice and progressing to a fulminant hepatic necrosis (in some cases fatal). Patients who during ACE inhibitor therapy experience jaundice or clearly elevated hepatic enzymes should discontinue Acupril and receive appropriate medical follow-up.

Cough:

Cough has been reported with the use of ACE inhibitors. Characteristically, the cough is non-productive, persistent and resolves after discontinuation of therapy. ACE inhibitor-induced cough should be considered as part of the differential diagnosis of cough.

Surgery/Anaesthesia:

In patients undergoing major surgery or during anaesthesia with agents that produce hypotension, Acupril may block angiotensin II formation secondary to compensatory renin release.).

Diabetic patients:

In diabetic patients ACE inhibitors may enhance insulin sensitivity and have been associated with hypoglycaemia in patients treated with oral antidiabetic agents or insulin. Glycaemic control should be closely monitored particularly during the first month of treatment with an ACE inhibitor.

Pregnancy

ACE inhibitors should not be initiated during pregnancy. Unless continued ACE inhibitor therapy is considered essential, patients planning pregnancy should be changed to alternative anti-hypertensive treatments which have an established safety profile for use in pregnancy. When pregnancy is diagnosed, treatment with ACE inhibitors should be stopped immediately, and, if appropriate, alternative therapy should be started.

ATC code: C09AA06

Pharmacotherapeutic group: Angiotensin-converting enzyme (ACE) inhibitor.

Acupril is rapidly de-esterified to Acuprilat (Acupril diacid, the principal metabolite), which is a potent angiotensin-converting enzyme (ACE) inhibitor.

ACE is a peptidyl dipeptidase that catalyses the conversion of angiotensin I to the vasoconstrictor angiotensin II which is involved in vascular control and function through many different mechanisms, including stimulation of aldosterone secretion by the adrenal cortex. The mode of action of Acupril in humans and animals is to inhibit circulating and tissue ACE activity, thereby decreasing vasopressor activity and aldosterone secretion.

In animal studies, the antihypertensive effect of Acupril outlasts its inhibitory effect on circulating ACE, whereas, tissue ACE inhibition more closely correlates with the duration of antihypertensive effects. Administration of 10-40 mg of Acupril to patients with mild to severe hypertension results in a reduction of both sitting and standing blood pressure with minimal effect on heart rate. Antihypertensive activity commences within one hour with peak effects usually achieved by two to four hours after dosing. Achievement of maximum blood pressure lowering effects may require two weeks of therapy in some patients. At the recommended doses, antihypertensive effects are maintained in most patients throughout the 24 hour dosing interval and continue during long term therapy.

In a randomised clinical trial using target doses of 2.5, 5, 10 and 20 mg of Acupril, 112 children and adolescents with hypertension or high normal blood pressure over 8 weeks (2 weeks double blind and 6 weeks extension), failed to reach its primary objective of reduction of diastolic blood pressure after 2 weeks. For systolic blood pressure (secondary objective of efficacy) at Week 2 only there was a statistically significant linear dose response across treatments with a significant difference between the Acupril 20 mg QD and placebo treatment groups.

Long term effects of Acupril on growth, puberty and general development have not been studied.

Two large randomised, controlled trials (ONTARGET (ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial) and VA NEPHRON-D (The Veterans Affairs Nephropathy in Diabetes)) have examined the use of the combination of an ACE-inhibitor with an angiotensin II receptor blocker.

ONTARGET was a study conducted in patients with a history of cardiovascular or cerebrovascular disease, or type 2 diabetes mellitus accompanied by evidence of end-organ damage. VA NEPHRON-D was a study in patients with type 2 diabetes mellitus and diabetic nephropathy.

These studies have shown no significant beneficial effect on renal and/or cardiovascular outcomes and mortality, while an increased risk of hyperkalaemia, acute kidney injury and/or hypotension as compared to monotherapy was observed. Given their similar pharmacodynamic properties, these results are also relevant for other ACE-inhibitors and angiotensin II receptor blockers.

ACE-inhibitors and angiotensin II receptor blockers should therefore not be used concomitantly in patients with diabetic nephropathy.

ALTITUDE (Aliskiren Trial in Type 2 Diabetes Using Cardiovascular and Renal Disease Endpoints) was a study designed to test the benefit of adding aliskiren to a standard therapy of an ACE-inhibitor or an angiotensin II receptor blocker in patients with type 2 diabetes mellitus and chronic kidney disease, cardiovascular disease, or both. The study was terminated early because of an increased risk of adverse outcomes. Cardiovascular death and stroke were both numerically more frequent in the aliskiren group than in the placebo group and adverse events and serious adverse events of interest (hyperkalaemia, hypotension and renal dysfunction) were more frequently reported in the aliskiren group than in the placebo group.

Peak plasma Acupril tablets concentrations are observed within 1 hour of oral administration. The extent of absorption is approximately 60%, and is not influenced by food. Following absorption, Acupril is de-esterified to its major active metabolite, Acuprilat, and to minor inactive metabolites. Acupril tablets have an apparent half-life of approximately one hour. Peak plasma Acuprilat concentrations are observed approximately 2 hours following an oral dose of Acupril. Acuprilat is eliminated primarily by renal excretion and has an effective accumulation half-life of 3 hours. In patients with renal insufficiency and creatinine clearance of ≤40ml/min, peak and trough Acuprilat concentrations increase, time to peak concentration increases, apparent half-life increases, and time to steady state may be delayed. The elimination of Acuprilat is also reduced in elderly patients >65 years) and correlates well with the impaired renal function which frequently occurs in the elderly. Acuprilat concentrations are reduced in patients with alcoholic cirrhosis due to impaired de-esterification of Acupril tablets. Studies in rats indicate that Acupril tablets and its metabolites do not cross the blood-brain barrier.

The pharmacokinetics of Acupril has been studied in a single dose study (0.2 mg/kg) in 24 children aged 2.5 months to 6.8 years and a multiple dose study (0.016-0.468 mg/kg) in 38 children aged 5-16 years old, weighing 66-98 kg on average.

As in adults, Acupril was rapidly converted to Acuprilat. Acuprilat concentrations generally peaked 1 to 2 hours post dose and declined with a mean half-life of 2.3 hours. In infants and young children the exposure following a single 0.2-mg/kg dose is comparable to that observed in adults after a single 10-mg dose. In a multiple dose study in school age and adolescents, the AUC and Cmax values of Acuprilat were observed to increase linearly with increasing dose of Acupril on a mg/kg basis.”

Lactation:

After a single oral dose of 20mg of Acupril in six breast-feeding women M/P (milk to plasma ratio) for Acupril was 0.12. Acupril was not detected in milk after 4 hours after the dose. Quinalaprilat milk levels were undetectable (<5µg/L) at all time points. It is estimated that a breastfed infant would receive about 1.6% of the material weight-adjusted dosage of Acupril.
