Idagor 5 mg/10 mg Film-Coated Tablets

Idagor is indicated as substitution therapy for treatment of essential hypertension, in adult patients already controlled with amlodipine and the fixed dose combination perindopril/indapamide, taken at the same dose levels as contained in Idagor.

Posology

One Idagor film-coated tablet per day as a single dose, preferably to be taken in the morning and before a meal. Idagor is not suitable for initial therapy. If a change of the posology is required, titration should be done with the individual components.

Special populations

Renal impairment (see sections 4.3 and 4.4) In severe renal impairment (creatinine clearance below 30 mL/min), treatment is contraindicated. In patients with moderate renal impairment (creatinine clearance 30 - 60 mL/min), Idagor at the doses 10/2,5/5 mg and 10/2,5/10 mg is contraindicated. It is recommended to start treatment with appropriate doses of the individual components. Frequent monitoring of blood pressure, creatinine and potassium should be done.

Concomitant use of perindopril with aliskiren is contraindicated in patients with renal impairment (GFR < 60 ml/min/1,73 m2) (see section 4.3).

Hepatic impairment (see sections 4.3, 4.4 and 5.2) Idagor is contraindicated in patients with moderate (Child Pugh B) and severe (Child Pugh C) hepatic impairment. Safety of Idagor has not been established in these patients.

Elderly (see section 4.4) Elimination of perindoprilat is decreased in the elderly (see section 5.2). Elderly can be treated with Idagor according to renal function (see section 4.3).

Paediatric population The safety and efficacy of Idagor in children and adolescents below 18 years of age, have not been established. No data are available.

Special warnings

Lithium

Lithium should not be used in combination with perindopril/indapamide as contained in Idagor (see sections 4.3 and 4.5).

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

The concomitant use of ACE-inhibitors, such as contained in Idagor angiotensin II receptor blockers or aliskiren increases the risk of hypotension, hyperkalaemia and decreased renal function (including acute renal failure). Should a woman become pregnant while receiving Idagor, the treatment must be stopped promptly and switched to a different class of antihypertensive medicine (s sections 4.3 and 4.6).

Dual blockade of the RAAS with ARBu2019s, ACE-inhibitors or aliskiren

Clinical trial data has shown that dual blockade of the renin-angiotensin-aldosterone-system (RAAS) through the combined use of ACE-inhibitors such as contained in Idagor, angiotensin II receptor blockers or aliskiren is associated with a higher frequency of adverse events such as hypotension, hyperkalaemia and decreased renal function (including acute renal failure) compared to the use of a single RAAS-acting agent (see sections 4.3, 4.4 and 5.1).

Medicines increasing the risk of angioedema

Concomitant use of ACE-inhibitors with sacubitril/valsartan is contraindicated as this increases the risk of angioedema (see section 4.3 and 4.4). Sacubitril/valsartan must not be started until 36 hours after taking the last dose of perindopril therapy. Perindopril therapy must not be started until 36 hours after the last dose of sacubitril/valsartan (see sections 4.3 and 4.4).

Medicines inducing hyperkalaemia

Some medicines or therapeutic classes may increase the occurrence of hyperkalaemia: aliskiren, potassium salts, potassium-sparing diuretics (e.g. spironolactone, triamterene or amiloride), ACE-inhibitors such as contained in Idagor, angiotensin-II receptors antagonists, NSAIDs, heparins, immunosuppressant agents such as ciclosporin or tacrolimus, trimethoprim and co-trimoxazole (trimethoprim/sulfamethoxazole), as trimethoprim is known to act as a potassium-sparing diuretic like amiloride. The combination of these medicine increases the risk of hyperkalaemia.

Idagor is contraindicated during pregnancy and lactation.

Pregnancy

The use of Idagor is contraindicated during pregnancy. Pregnant women should be informed of the potential hazards to the foetus and must not take Idagor during pregnancy (see section 4.3). 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 Idagor should be stopped immediately and if appropriate, alternative therapy should be started. Foetal exposure to ACE-inhibitors during the first trimester of pregnancy has been reported to be associated with an increased risk of malformations of the cardiovascular (atrial and/or ventricular septal defect, pulmonic stenosis, patent ductus arteriosus) and central nervous system (microcephaly, spina bifida) and of kidney malformations.

Idagor passes through the placenta and causes disturbance in foetal blood pressure regulatory mechanisms. Oligohydramnios as well as hypotension, oliguria and anuria in newborns, have been reported after administration of ACE-inhibitors, such as Idagor, during the second and third trimester. Cases of defective skull ossification have been observed. Prematurity and low birth mass can occur (see section 4.3).

Indapamide

There are no or limited amount of data (less than 300 pregnancy outcomes) from the use of indapamide in pregnant women. Prolonged exposure to thiazide during the third trimester of pregnancy can reduce maternal plasma volume as well as uteroplacental blood flow, which may cause a feto-placental ischemia and growth retardation. Moreover, cases of hypoglycemia and thrombocytopenia in neonates have been reported following exposure near term. Animal studies do not indicate direct or indirect harmful effects with respect to reproductive toxicity (see section 5.3).

Amlodipine

The safety of amlodipine in human pregnancy has not been established. In animal studies, reproductive toxicity was observed at high doses (see section 5.3).

Breastfeeding

Idagor is contraindicated during lactation.

Perindopril

Because no information is available regarding the use of perindopril during breastfeeding, perindopril is not recommended and alternative treatments with better established safety profiles during breastfeeding are preferable, especially while nursing a newborn or preterm infant.

Indapamide

There is insufficient information on the excretion of indapamide/metabolites in human milk. Hypersensitivity to sulphonamide-derived medicines and hypokalaemia might occur. A risk to newborns/infants cannot be excluded. Indapamide is closely related to thiazide diuretics which have been associated, during breastfeeding, with a decrease or even suppression of milk lactation.

Amlodipine

Amlodipine is excreted in human milk. The proportion of the maternal dose received by the infant has been estimated with an interquartile range of 3 u2013 7 %, with a maximum of 15 %. The effect of amlodipine on infants is unknown.

Fertility

Common to perindopril and indapamide Reproductive toxicity studies showed no effect on fertility in female and male rats (see section 5.3). No effects on human fertility are anticipated.

Amlodipine

Reversible biochemical changes in the head of spermatozoa have been reported in some patients treated by calcium channel blockers. Clinical data are insufficient regarding the potential effect of amlodipine on fertility. In one rat study, adverse effects were found on male fertility (see section 5.3).

No studies on the effects of Idagor on the ability to drive and use machines have been performed. Idagor may affect the ability to drive and use machines. Patients should not drive and use machines until they know how the treatment with Idagor affects them.

Perindopril and indapamide may cause hypotension which may affect the ability of patients to drive and use machines. Amlodipine can cause hypotension, dizziness, headache, visual impairment, fatigue, weariness or nausea, which may impair the ability to drive and use machines.

Summary of the safety profile. The most commonly reported adverse reactions with perindopril, indapamide and amlodipine given separately are: hypokalaemia, dizziness, headache, paraesthesia, somnolence, dysgeusia, visual impairment, diplopia, tinnitus, vertigo, palpitations, flushing, hypotension (and effects related to hypotension), cough, dyspnoea, gastro-intestinal disorders (abdominal pain, constipation, diarrhoea, dyspepsia, nausea, vomiting, change of bowel habit), pruritus, rash, rash maculo-papular, muscle spasms, ankle swelling, asthenia, oedema and fatigue.

Tabulated list of adverse reactions The following undesirable effects have been observed with perindopril, indapamide or amlodipine during treatment and ranked under the following frequency: Very common ( u2265 1/10); common ( u2265 1/100 to < 1/10); uncommon ( u2265 1/1 000 to < 1/100); rare ( u2265 1/10 000 to < 1/1 000); very rare (< 1/10 000); not known (cannot be estimated from the available data).

There is no information on overdosage with Idagor in humans.

For perindopril/indapamide combination Symptoms The most likely adverse reaction in cases of overdose is hypotension, sometimes associated with nausea, vomiting, cramps, dizziness, sleepiness, mental confusion, oliguria which may progress to anuria (due to hypovolaemia). Salt and water disturbances (low sodium levels, low potassium levels) may occur.

Management The first measures to be taken consist of rapidly eliminating the product(s) ingested by gastric lavage and/or administration of activated charcoal, and restoring the fluid and electrolyte balance. If marked hypotension occurs, this can be treated by placing the patient in a supine position with the head lowered. If necessary an intravenous infusion of 0,9 % sodium chloride (isotonic saline) may be given, or any other method of volaemic expansion may be used. Perindoprilat, the active form of perindopril, can be dialysed (see section 5.2).

For amlodipine, Experience with intentional overdose in humans is limited. Symptoms Available data suggest that gross 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. Non-cardiogenic pulmonary oedema has rarely been reported as a consequence of amlodipine overdose that may manifest with a delayed onset (24 - 48 hours post-ingestion) and require ventilatory support. Early resuscitative measures (including fluid overload) to maintain perfusion and cardiac output may be precipitating factors.

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.
