Pharmacotherapeutic Group: Angiotensin II antagonists, plain (telmisartan), combinations with dihydropyridine derivatives (amlodipine).
Pharmacology: Mode of action: Telmisartan + Amlodipine besilate combines two antihypertensive compounds with complementary mechanisms to control blood pressure in patients with essential hypertension: an angiotensin II receptor antagonist, telmisartan, and a dihydropyridine calcium channel blocker, amlodipine.
The combination of these substances has an additive antihypertensive effect, reducing blood pressure to a greater degree than either component alone.
Telmisartan + Amlodipine besilate once daily produces effective and consistent reductions in blood pressure across the 24-hour therapeutic dose range.
Telmisartan: Telmisartan is an orally effective and specific angiotensin II receptor (type AT1) antagonist. Telmisartan displaces angiotensin II with very high affinity from its binding site at the AT1 receptor subtype, which is responsible for the known actions of angiotensin II. Telmisartan does not exhibit any partial agonist activity at the AT1 receptor. Telmisartan selectively binds the AT1 receptor. The binding is long lasting. Telmisartan does not show affinity for other receptors, including AT2 and other less characterised AT receptors. The functional role of these receptors is not known, nor is the effect of their possible overstimulation by angiotensin II, whose levels are increased by telmisartan.
Plasma aldosterone levels are decreased by telmisartan. Telmisartan does not inhibit human plasma renin or block ion channels. Telmisartan does not inhibit angiotensin converting enzyme (kininase II), the enzyme which also degrades bradykinin. Therefore it is not expected to potentiate bradykinin-mediated adverse effects.
In man, an 80 mg dose of telmisartan almost completely inhibits the angiotensin II evoked blood pressure increase. The inhibitory effect is maintained over 24 hours and still measurable up to 48 hours.
Amlodipine: Amlodipine is a calcium ion influx inhibitor of the dihydropyridine group (slow channel blocker or calcium ion antagonist) and inhibits the transmembrane influx of calcium ions into cardiac and vascular smooth muscle.
The mechanism of the antihypertensive action of amlodipine is due to a direct relaxant effect on vascular smooth muscle, leading to reductions in peripheral vascular resistance and in blood pressure. Experimental data indicate that amlodipine binds to both dihydropyridine and non-dihydropyridine binding sites. Amlodipine is relatively vessel-selective, with a greater effect on vascular smooth muscle cells than on cardiac muscle cells.

Treatment of essential hypertension.
Replacement Therapy: Patients receiving telmisartan and amlodipine besilate from separate tablets may instead receive Telmisartan + Amlodipine containing the same component doses.
Add on Therapy: Telmisartan + Amlodipine besilate is indicated in patients whose blood pressure is not adequately controlled on telmisartan or amlodipine monotherapy.
Initial therapy: Telmisartan + Amlodipine besilate may also be used as initial therapy in patients who are likely to need multiple drugs to achieve their blood pressure goals. The choice of Telmisartan + Amlodipine besilate as initial therapy for hypertension should be based on an assessment of potential benefits and risks.

Adults: Telmisartan + Amlodipine besilate should be taken once daily.
Replacement therapy: Patients receiving telmisartan and amlodipine besilate from separate tablets can instead receive Telmisartan + Amlodipine besilate containing the same component doses in one tablet once daily, e.g. to enhance convenience or compliance.
Add on therapy: Telmisartan + Amlodipine besilate may be administered in patients whose blood pressure is not adequately controlled with amlodipine or telmisartan alone. Patients treated with 10 mg amlodipine who experience any dose limiting adverse reactions such as oedema, may be switched to Telmisartan + Amlodipine besilate 40 mg/5 mg once daily, reducing the dose of amlodipine without reducing the overall expected antihypertensive response.
Initial therapy: A patient may be initiated on Telmisartan + Amlodipine besilate if it is unlikely that control of blood pressure would be achieved with a single agent. The usual starting dose of Telmisartan + Amlodipine besilate is 40 mg/5 mg once daily. Patients requiring larger blood pressure reductions may be started on Telmisartan + Amlodipine besilate 80 mg/5 mg once daily. If additional blood pressure lowering is needed after at least 2 weeks of therapy, the dose may be titrated up to a maximum of 80 mg/10 mg once daily. Telmisartan + Amlodipine besilate can be administered with other antihypertensive drugs.
Special population: Renal impairment: No posology adjustment is required for patients with renal impairment, including those on haemodialysis. Amlodipine and telmisartan are not dialyzable.
Hepatic impairment: In patients with mild to moderate hepatic impairment Telmisartan + Amlodipine besilate should be administered with caution. For telmisartan the posology should not exceed 40 mg once daily.
Elderly patients: No dose adjustment is necessary for elderly patients. Normal amlodipine dosage regimens are recommended in the elderly, but increase of dosage should take place with care.
Pediatric population: Telmisartan + Amlodipine besilate is not recommended for use in patients aged below 18 years due to a lack of data on safety and efficacy.
Method of Administration: Tablet for oral administration. Telmisartan + Amlodipine besilate may be taken with or without food.

Symptoms: There is no experience of overdose with Telmisartan + Amlodipine besilate. Signs and symptoms of overdose are expected to be in line with exaggerated pharmacological effects. The most prominent manifestations of telmisartan overdosage were hypotension, tachycardia; bradycardia might also occur. Overdose with amlodipine may result in excessive peripheral vasodilation and possibly reflex tachycardia. Marked and probably prolonged systemic hypotension, including shock, with fatal outcome may occur.
Therapy: Supportive treatment should be instituted. Intravenous calcium gluconate may be beneficial in reversing the effects of calcium channel blockade. Telmisartan and amlodipine besilate are not removed by haemodialysis.

Hypersensitivity to the active substances, or to any of the excipients.
Hypersensitivity to dihydropyridine derivatives.
Second and third trimesters of pregnancy.
Lactation.
Biliary obstructive disorders.
Severe hepatic impairment.
Cardiogenic shock.
The concomitant use of Telmisartan + Amlodipine besilate with aliskiren is contraindicated in patients with diabetes mellitus or renal impairment (GFR <60 mL/min/1.73 m²).
In case of rare hereditary conditions that may be incompatible with an excipient of the product, the use of the product is contraindicated.

Hepatic impairment: Telmisartan is mostly eliminated in the bile. Patients with biliary obstructive disorders or hepatic insufficiency can be expected to have reduced clearance. Furthermore, as with all calcium antagonists, amlodipine half-life is prolonged in patients with impaired liver function and dosage recommendations have not been established. Telmisartan + Amlodipine besilate should therefore be used with caution in these patients.
Renovascular hypertension: There is an increased risk of severe hypotension and renal insufficiency when patients with bilateral renal artery stenosis or stenosis of the artery to a single functioning kidney are treated with medicinal products that affect the renin-angiotensin-aldosterone system.
Renal impairment and kidney transplant: When Telmisartan + Amlodipine besilate is used in patients with impaired renal function, a periodic monitoring of potassium and creatinine serum levels is recommended. There is no experience regarding the administration of Telmisartan + Amlodipine besilate in patients with a recent kidney transplant. Telmisartan and amlodipine besilate are not dialyzable.
Intravascular hypovolaemia: Symptomatic hypotension, especially after the first dose, may occur in patients who are volume and/or sodium depleted by e.g. vigorous diuretic therapy, dietary salt restriction, diarrhoea or vomiting. Such conditions should be corrected before the administration of Telmisartan + Amlodipine besilate.
Dual blockade of the renin-angiotensin-aldosterone system: As a consequence of inhibiting the renin-angiotensin-aldosterone system changes in renal function (including acute renal failure) have been reported in susceptible individuals, especially if combining medicinal products that affect this system. Telmisartan + Amlodipine besilate can be administered with other antihypertensive drugs, however dual blockade of the renin-angiotensin-aldosterone system (e.g. by adding an ACE Inhibitor or the direct renin-inhibitor aliskiren to an angiotensin II receptor antagonists) is not recommended and should therefore be limited to individually defined cases with close monitoring or renal function.
Other conditions with stimulation of the renin-angiotensin-aldosterone system: In patients whose vascular tone and renal function depend predominantly on the activity of the renin-angiotensin-aldosterone system (e.g. patients with severe congestive heart failure or underlying renal disease, including renal artery stenosis), treatment with medicinal products that affect this system has been associated with acute hypotension, hyperazotemia, oliguria, or rarely acute renal failure.
Primary aldosteronism: Patients with primary aldosteronism generally will not respond to antihypertensive medicinal products acting through inhibition of the renin-angiotensin system. Therefore, the use of telmisartan is not recommended.
Aortic and mitral valve stenosis, obstructive hypertrophic cardiomyopathy: As with other vasodilators, special caution is indicated in patients suffering from aortic or mitral stenosis, or obstructive hypertrophic cardiomyopathy.
Unstable angina pectoris, acute myocardial infarction: There are no data to support the use of Telmisartan + Amlodipine besilate in unstable angina pectoris and during or within one month of a myocardial infarction.
Patients with cardiac failure: In a long-term, placebo controlled study (PRAISE-2) of amlodipine in patients with NYHA III and IV heart failure of nonischaemic aetiology, amlodipine was associated with increased reports of pulmonary oedema despite no significant difference in the incidence of worsening heart failure as compared to placebo.
Hyperkalaemia: During treatment with medicinal products that affect the renin-angiotensin-aldosterone system hyperkalaemia may occur, especially in the presence of renal impairment and/or heart failure. Monitoring of serum potassium in patients at risk is recommended. Based on experience with the use of medicinal products that affect the renin-angiotensin system, concomitant use with potassium-sparing diuretics, potassium supplements, salt substitutes containing potassium or other medicinal products that may increase the potassium level (heparin, etc,) may lead to an increase in serum potassium and should therefore be co-administered cautiously with telmisartan.
Diabetes mellitus: In diabetic patients with an additional cardiovascular risk, i.e. patients with diabetes mellitus and coexistent coronary artery disease (CAD), the risk of fatal myocardial infarction and unexpected cardiovascular death may be increased when treated with blood pressure lowering agents such as ARBs or ACE-inhibitors. In patients with diabetes mellitus CAD may be asymptomatic and therefore undiagnosed. Patients with diabetes mellitus should undergo appropriate diagnostic evaluation, e.g. exercise stress testing, to detect and to treat CAD accordingly before initiating treatment with Telmisartan + Amlodipine besilate.
Other: Telmisartan + Amlodipine besilate was effective when treating black patients (usually a low-renin population). As with any antihypertensive agent, excessive reduction of blood pressure in patients with ischaemic cardiopathy or ischaemic cardiovascular disease could result in a myocardial infarction or stroke.
Effects on ability to drive and use machines: No studies on the effects on the ability to drive and use machines have been performed. However, patients should be advised that they may experience undesirable effects such as syncope, somnolence, dizziness, or vertigo during treatment. Therefore, caution should be recommended when driving a car or operating machinery. If patients experience these adverse experiences, they should avoid potentially hazardous tasks such as driving or operating machinery.

Pregnancy: Telmisartan: The use of angiotensin II receptor antagonists is not recommended during the first trimester of pregnancy and should not be initiated during pregnancy. When pregnancy is diagnosed, treatment with angiotensin II receptor antagonists should be stopped immediately, and, if appropriate, alternative therapy should be started. The use of angiotensin II receptor antagonists is contraindicated during the second and third trimesters of pregnancy. Non-clinical studies with telmisartan do not indicate teratogenic effect, but have shown fetotoxicity. Angiotensin II receptor antagonists' exposure during the second and third trimesters is known to induce human fetotoxicity (decreased renal function, oligohydramnios, skull ossification retardation) and neonatal toxicity (renal failure, hypotension, hyperkalaemia). Unless continued angiotensin II receptor antagonist 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. Should exposure to angiotensin II receptor antagonists have occurred from the second trimester of pregnancy, ultrasound check of renal function and skull is recommended. Infants whose mothers have taken angiotensin II receptor antagonists should be closely observed for hypotension.
Amlodipine: Data on a limited number of exposed pregnancies do not indicate that amlodipine or other calcium receptor antagonists have a harmful effect on the health of the fetus. However, there may be a risk of prolonged delivery.
Lactation: It is not known whether telmisartan is excreted in human milk. Non-clinical studies have shown excretion of telmisartan in breast milk. Amlodipine has been identified in breastfed infants of treated women. The effect of amlodipine on infants is unknown. Because of the potential adverse reactions in nursing infants, a decision should be made whether to discontinue nursing or to discontinue therapy, taking into account the importance of this therapy for the mother.
Fertility: No data from controlled clinical studies with the Fixed Dose Combination or with the individual components are available. Separate reproductive toxicity studies with the combination of telmisartan and amlodipine have not been conducted. In non-clinical studies, no effects of telmisartan on male and female fertility were observed. Similarly, no effects on male and female fertility were reported for amlodipine.

Fixed Dose Combination: The safety and tolerability of Telmisartan + Amlodipine besilate has been evaluated in five controlled clinical studies with over 3500 patients, over 2500 of whom received telmisartan in combination with amlodipine.

No interactions between the two components of this fixed dose combinations have been observed in clinical studies.
Interactions common to the combination: No drugs interaction studies have been performed with Telmisartan + Amlodipine besilate and other medicinal products.
Concomitant use to be taken into account: Other antihypertensive agents: The blood pressure lowering effect of Telmisartan + Amlodipine besilate can be increased by concomitant use of other antihypertensive medicinal products.
Agents with blood pressure lowering potential: Based on their pharmacological properties it can be expected that the following medicinal products may potentiate the hypotensive effects of all antihypertensives including Telmisartan + Amlodipine besilate, e.g. baclofen, amifostine. Furthermore, orthostatic hypotension may be aggravated by alcohol, barbiturates, narcotics, or antidepressants.
Corticosteroids (systemic route): Reduction of the antihypertensive effect.
Interactions linked to telmisartan: Telmisartan may increase the hypotensive effect of other antihypertensive agents.
Co-administration of telmisartan did not result in a clinically significant interaction with digoxin, warfarin, hydrochlorothiazide, glibenclamide, ibuprofen, paracetamol, simvastatin, and amlodipine. For digoxin a 20% increase in median plasma digoxin trough concentration has been observed (39% in a single case), monitoring of plasma digoxin levels should be considered.
In one study the co-administration of telmisartan and ramipril led to an increase of up to 2.5 fold in the AUC_0-24 and C_max of ramipril and ramiprilat. The clinical relevance of this observation is not known.
Reversible increases in serum lithium concentrations and toxicity have been reported during concomitant administration of lithium with angiotensin converting enzyme inhibitors. Cases have also been reported with angiotensin II receptor antagonists including telmisartan. Therefore, serum lithium level monitoring is advisable during concomitant use.

Store at temperatures not exceeding 30°C. Protect from moisture.
