TELMISAR TELMISARtan 40mg Film-Coated Tablet 1's

For the treatment of hypertension and cardiovascular risk reduction in patients unable to take Angiotensin-Converting Enzyme (ACE) Inhibitors.

 

Route of Administration: Oral.
Treatment of Essential Hypertension: The usually effective dose is 40 mg once daily. Some patients may already benefit at a daily dose of 20 mg. In cases where the target blood pressure is not achieved, the dose of Telmisartan can be increased to a maximum of 80 mg once daily. Alternatively, Telmisartan may be used in combination with thiazide type diuretics such as hydrochlorothiazide, which has been shown to have an additive blood pressure lowering effect with Telmisartan. When considering raising the dose, it must be borne in mind that the maximum antihypertensive effect is generally attained four to eight weeks after the start of treatment.
Cardiovascular Prevention: The recommended dose is 80 mg once daily. It is not known whether doses lower than 80 mg of Telmisartan are effective in reducing cardiovascular morbidity.
When initiating Telmisartan therapy for the reduction of cardiovascular morbidity, close monitoring of blood pressure is recommended, and if appropriate adjustment of medications that lower blood pressure may be necessary. Telmisartan may be taken with or without food.
Special Patient Populations: Renal Impairment: No posology adjustment is required for patients with mild to moderate renal impairment. Limited experience is available in patients with severe renal impairment or haemodialysis. A lower starting dose of 20 mg is recommended in these patients.
Hepatic impairment: In patients with mild to moderate hepatic impairment, the posology should not exceed 40 mg once daily.
Elderly: No dose adjustment is necessary for elderly patients.
Paediatric Patients: Telmisartan is not recommended for use in children below 18 years due to a lack of data on safety and efficacy.

 

Overdosage

May be taken with or without food.

Hypersensitivity to the active substance or to any of the excipients.
Second and third trimesters of pregnancy.
Biliary obstructive disorders.
Severe hepatic impairment.

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.
Intravascular Hypovolaemia: Symptomatic hypotension, especially after the first dose of Telmisartan, may occur in patients who are volume and/or sodium depleted by vigorous diuretic therapy, dietary salt restriction, diarrhoea, or vomiting. Such conditions should be corrected before the administration of Telmisartan. Volume and/or sodium depletion should be corrected prior to administration of Telmisartan.
Dual Blockade of the Renin-Angiotensin-Aldosterone System: As a consequence of inhibiting the renin-angiotensin-aldosterone system, hypotension, syncope, hyperkalaemia, and changes in renal function (including acute renal failure) have been reported in susceptible individuals, especially if combining medicinal products that affect this system. Dual blockade of the renin-angiotensin-aldosterone system (e.g. by adding an ACE-inhibitor to an angiotensin II receptor antagonist) is therefore not recommended in patients with already controlled blood pressure and should be limited to individually defined cases with close monitoring of 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 such as Telmisartan has been associated with acute hypotension, hyperazotaemia, 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.
Hyperkalaemia: The use of medicinal products that affect the renin-angiotensin-aldosterone system may cause hyperkalaemia. In the elderly, in patients with renal insufficiency, in diabetic patients, in patients concomitantly treated with other medicinal products that may increase potassium levels, and/or in patients with intercurrent events, hyperkalaemia may be fatal. Before considering the concomitant use of medicinal products that affect the renin angiotensin aldosterone system, the benefit risk ratio should be evaluated.
The main risk factors for hyperkalaemia to be considered are: Diabetes mellitus, renal impairment, age (>70 years).
Combination with one or more other medicinal products that affect the renin angiotensin-aldosterone system and/or potassium supplements. Medicinal products or therapeutic classes of medicinal products that may provoke hyperkalaemia are salt substitutes containing potassium, potassium-sparing diuretics, ACE inhibitors, angiotensin II receptor antagonists, non-steroidal anti-inflammatory medicinal products (NSAIDs, including selective COX-2 Inhibitors), heparin, immunosuppressives (cyclosporin or tacrolimus), and trimethoprim.
Intercurrent events, in particular dehydration, acute cardiac decompensation, metabolic acidosis, worsening of renal function, sudden worsening of the renal condition (e.g. infectious diseases), cellular lysis (e.g. acute limb ischemia, rhabdomyolysis. Close monitoring of serum potassium in at risk patients is recommended.
Sorbitol: This medicinal product contains sorbitol. Patients with rare hereditary problems of fructose intolerance should not take Telmisartan.
Ethnic Differences: As observed for angiotensin converting enzyme inhibitors, Telmisartan and the other angiotensin II receptor antagonists are apparently less effective in lowering blood pressure in black people than in non-blacks, possibly because of higher prevalence of low-renin states in the black hypertensive population.
Other: 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.
Hepatic Impairment: Telmisartan is not to be given to patients with cholestasis, biliary obstructive disorders or severe hepatic impairment since Telmisartan is mostly eliminated with the bile. These patients can be expected to have reduced hepatic clearance for Telmisartan. Telmisartan should be used only with caution in patients with mild to moderate hepatic impairment.
Renal Impairment and Kidney Transplantation: When Telmisartan is used in patients with impaired renal function, periodic monitoring of potassium and creatinine serum levels is recommended. There is no experience regarding the administration of Telmisartan in patients with recent kidney transplantation.
Use in Pregnancy: Angiotensin II receptor antagonists should not be initiated during pregnancy. Unless continued angiotensin II receptor antagonist therapy is considered essential, patients planning pregnancy should be changed to alternative antihypertensive treatments which have an established safety profile for use in pregnancy. When pregnancy is diagnosed, treatment with angiotensin II receptor antagonists should be stopped immediately, and, if appropriate, alternative therapy should be started.

Interaction studies have only been performed in adults. As with other medicinal products acting on the renin-angiotensin-aldosterone system, Telmisartan may provoke hyperkalaemia. The risk may increase in case of treatment combination with other medicinal products that may also provoke hyperkalaemia (salt substitutes containing potassium, potassium-sparing diuretics, Angiotensin-Converting Enzyme (ACE) inhibitors, angiotensin II receptor antagonists, Non-Steroidal Anti-Inflammatory Medicinal Products (Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)), including selective (Cyclooxygenase (Cox-2) Inhibitors), heparin, immunosuppressives (cyclosporin or tacrolimus), and trimethoprim). The occurrence of hyperkalaemia depends on associated risk factors. The risk is increased in case of the previously mentioned treatment combinations. The risk is particularly high in combination with potassium sparing-diuretics, and when combined with salt substitutes containing potassium. A combination with ACE inhibitors or NSAIDs, for example, presents a lesser risk provided that precautions for use are strictly followed.
Concomitant Use: Not recommended.
Potassium Sparing Diuretics or Potassium Supplements: Angiotensin II receptor antagonists such as Telmisartan, attenuate diuretic induced potassium loss. Potassium sparing diuretics e.g. spirinolactone, eplerenone, triamterene, or amiloride, potassium supplements, or potassium-containing salt substitutes may lead to a significant increase in serum potassium. If concomitant use is indicated because of documented hypokalaemia, they should be used with caution and with frequent monitoring of serum potassium.
Lithium: Reversible increases in serum lithium concentrations and toxicity have been reported during concomitant administration of lithium with angiotensin converting enzyme inhibitors, and with angiotensin II receptor antagonists, including Telmisartan. If use of the combination proves necessary, careful monitoring of serum lithium levels is recommended.
Concomitant Use Requiring Caution: Non-Steroidal Anti-Inflammatory Medicinal Products: Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) (i.e. acetylsalicylic acid at anti-inflammatory dosage regimens, Cyclooxygenase (COX-2) inhibitors and non-selective NSAIDs) may reduce the antihypertensive effect of angiotensin II receptor antagonists. In some patients with compromised renal function (e.g. dehydrated patients or elderly patients with compromised renal function), the co-administration of angiotensin II receptor antagonists and agents that inhibit Cyclooxygenase may result in further deterioration of renal function, including possible acute renal failure, which is usually reversible. Therefore, the combination should be administered with caution, especially in the elderly. Patients should be adequately hydrated and consideration should be given to monitoring of renal function after initiation of concomitant therapy and periodically thereafter. In one study the co-administration of Telmisartan and ramipril led to an increase of up to 2.5 fold in the AUC0-24 and Cmax of ramipril and ramiprilat. The clinical relevance of this observation is not known.
Diuretics (thiazide or loop diuretics): Prior treatment with high dose diuretics such as furosemide (loop diuretic) and hydrochlorothiazide (thiazide diuretic) may result in volume depletion, and in a risk of hypotension when initiating therapy with Telmisartan. To be taken into account with concomitant use.
Other antihypertensive agents: The blood pressure lowering effect of Telmisartan can be increased by concomitant use of other antihypertensive medicinal products. Based on their pharmacological properties it can be expected that the following medicinal products may potentiate the hypotensive effects of all antihypertensives including Telmisartan: Baclofen, amifostine. Furthermore, orthostatic hypotension may be aggravated by alcohol, barbiturates, narcotics, or antidepressants.
Corticosteroids (Systemic Route): Reduction of the antihypertensive effect.
