Telzap AM pills 10mg +80mg, 28pcs

Composition

1 tablet of 10 mg + 80 mg contains:  active ingredients:  amlodipine-10,000 mg (as amlodipine bezylate-13,870 mg), telmisartan-80,000 mg; excipients:  sorbitol, sodium hydroxide, povidone K 25, microcrystalline cellulose, calcium hydrophosphate dihydrate, meglumine, magnesium stearate.

Pharmacological action

The drug Telzap ® AM contains two antihypertensive substances with complementary mechanisms of action that provide control of blood pressure (BP) in patients with essential arterial hypertension; amlodipine belongs to the pharmacological group of slow calcium channel blockers (BMCC), and telmisartan belongs to the group of angiotensin II receptor antagonists (ARA II). The combination of these substances exhibits an additive antihypertensive effect, causing a more pronounced decrease in blood pressure than each of the components of the drug separately.

Amlodipine

Amlodipine-a dihydropyridine derivative, belongs to the BMCC class, inhibits the transmembrane supply of calcium ions to cardiomyocytes and smooth muscle cells of blood vessels. The mechanism of antihypertensive action of amlodipine is associated with the vasodilating effect on vascular smooth muscles. The exact mechanism by which amlodipine reduces the frequency and severity of angina attacks is not fully understood, but amlodipine can reduce myocardial ischemia due to the following two effects: :

amlodipine dilates the peripheral arterioles and thereby reduces the total peripheral vascular resistance (OPSS), the so-called afterload. Since the heart rate (HR) when taking amlodipine practically does not increase, this reduction in the load on the heart muscle reduces the energy consumption of the myocardium and its oxygen demand.

the mechanism of antianginal action of amlodipine also seems to be associated with dilation of the main coronary arteries and arterioles, both in areas of the myocardium with normal blood flow and in ischemic areas. This dilation increases oxygen delivery to the myocardium in patients with coronary artery spasm (Prinzmetal angina or variant angina).

In patients with arterial hypertension, taking amlodipine once a day provides a clinically significant reduction in blood pressure in the “lying” and “standing” positions for 24 hours. Orthostatic hypotension is not characteristic during the use of amlodipine due to the slow onset of action of the drug.

In patients with arterial hypertension and normal renal function, amlodipine at therapeutic doses leads to a decrease in renal vascular resistance, an increase in glomerular filtration rate and effective plasma flow in the kidneys without changing filtration or proterinuria.

No adverse metabolic effects or changes in plasma lipid concentrations were observed when taking amlodipine. Amlodipine can be taken in patients with asthma, diabetes, and gout. The use of amlodipine in patients with heart failure is not accompanied by a negative inotropic effect (exercise tolerance does not decrease, the left ventricular ejection fraction does not decrease).

Telmisartan

Mechanism of action

Telmisartan is a specific ARA II (type AT1) that is effective when taken orally. Having a very high affinity for the binding site of the AT1 receptor subtype with angiotensin II. telmisartan displaces angiotensin II from binding to the receptor, without having an agonist effect on this receptor. Telmisartan does not exhibit the properties of a partial agonist of the AT1 receptor. Telmisartan selectively binds to the AT1 receptor. Communication with the receptor is long-term.

Telmisartan does not show affinity for other receptors, including AT-2 receptors and other less well-studied angiotensin receptors. Telmisartan reduces the concentration of aldosterone in blood plasma, does not inhibit renin and does not block ion channels. Telmisartan does not inhibit the activity of angiotensin-converting enzyme (ACE) (kininase II), an enzyme that also destroys bradykinin. This suggests that the drug will not increase the adverse events associated with the action of bradykinin.

A dose of telmisartan 80 mg per day almost completely stops the increase in blood pressure under the influence of angiotensin II.

The antihypertensive effect persists for 24 hours and remains significant for 48 hours.

After taking the first dose of telmisartan, the antihypertensive effect develops gradually over 3 hours. A pronounced antihypertensive effect usually develops 4-8 weeks after regular use. The effect persists for 24 hours after taking telmisartan and remains significant for up to 48 hours.

In patients with arterial hypertension, telmisartan reduces SBP and DBP without affecting heart rate. After abrupt discontinuation of treatment with telmisartan, there is a gradual (over several days) return of blood pressure indicators to their values before starting the drug without the development of “withdrawal”syndrome.

In patients treated with telmisartan, the incidence of dry cough was significantly lower than in patients treated with ACE inhibitors. These data were obtained in clinical trials with a direct comparison of these two types of antihypertensive therapy.

The combined preparation of amlodipine and telmisartan, used once a day, leads to an effective and sustained decrease in blood pressure for 24 hours

. Pharmacokinetics

Amlodipine

Suction

After oral use of amlodipine in therapeutic doses, the maximum plasma concentrations are reached in 6-12 hours. The absolute bioavailability of the drug is 64-80%. Food intake does not affect the bioavailability of amlodipine.

Distribution

The apparent volume of distribution (Vd) is approximately 21 l / kg. In vitro studies have shown that about 97.5% of amlodipine circulating in the blood is bound to plasma proteins.

Biotransformation

Amlodipine is largely (approximately 90%) metabolized in the liver to form inactive metabolites.

The elimination

of T 1/2 of amlodipine from the blood plasma is approximately 35-50 hours, which confirms the possibility of using it once a day. The drug is excreted by the kidneys: 10% of the administered dose of the drug is eliminated in the form of the initial compound and 60% in the form of metabolites. The elimination of amlodipine from the blood plasma occurs in two phases.

Special patient populations

Patients with impaired liver function

There is very limited clinical data on the use of amlodipine in patients with impaired liver function. In patients with hepatic insufficiency, a decrease in clearance of amlodipine was observed, which led to an elongation of T 1/2 and an increase in AUC by approximately 40-60%.

Elderly patients

The time to reach the maximum concentration (tmax) of amlodipine in blood plasma is comparable in elderly patients and in younger patients. In elderly patients, the clearance rate of amlodipine tends to decrease with a corresponding increase in AUC and prolongation of T 1/2.

Telmisartan

Suction

Telmisartan is rapidly absorbed, but the amount of drug absorbed may vary. The average absolute bioavailability of telmisartan is approximately 50%. When taking telmisartan with food, there is a decrease in the area under the concentration-time curve (AUC) from approximately 6% (when taking telmisartan at a dose of 40 mg per day) to 19% (at a dose of 160 mg per day).3 hours after taking the drug, the concentration of telmisartan in the blood plasma is leveled, regardless of food intake.

Distribution

Telmisartan is characterized by a high degree of binding to plasma proteins (> 99.5%), mainly to albumin and alpha-1-acid glycoprotein. The average apparent volume of distribution at steady state (Vdss) is approximately 500 liters.

Biotransformation

The metabolism of telmisartan consists in conjugation of the parent compound with glucuronic acid. The resulting conjugate has no pharmacological activity.

Deduction

The half-life (T 1/2) is more than 20 hours. The maximum plasma concentration (Cmax) and, to a lesser extent, AUC increase disproportionately to the dose increase. There are no data on clinically significant accumulation of telmisartan taken at the recommended doses. It is excreted through the intestines in unchanged form, excretion by the kidneys-less than 1%. Total plasma clearance is high (about 1000 ml / min) compared to “hepatic” blood flow (about 1500 ml / min).

Linearity / non-linearity of pharmacokinetics

There was no linear relationship between the dose of the drug and its plasma concentration. Cmax and, to a lesser extent, AUC increase disproportionately at doses higher than 40 mg per day.

Special patient populations

Gender of patients

There were differences in the concentration of the drug in blood plasma in men and women: the Cmax and AUC values in women were approximately 3 and 2 times higher than in men, respectively.

Elderly patients

The pharmacokinetics of telmisartan did not differ between elderly patients and patients under 65 years of age.

Patients with impaired renal function

In patients with mild, moderate and severe renal impairment, a 2-fold increase in the concentration of telmisartan in blood plasma was observed. However, in patients with renal insufficiency undergoing hemodialysis, plasma concentrations of the drug were lower. Telmisartan is characterized by a high degree of binding to plasma proteins and is not eliminated from the body by hemodialysis.T 1/2 did not change in patients with impaired renal function.

Patients with impaired liver function

The results of pharmacokinetic studies showed an increase in the absolute bioavailability of telmisartan to almost 100% in patients with impaired liver function. T 1/2 did not change in patients with hepatic impairment.

Interaction

Interactions between the two active substances that make up this drug in fixed doses were not detected in clinical studies.

Studies on the drug interactions of Telzap ® AM with other drugs have not been conducted.

Interaction with amlodipine

Effect of other drugs on the pharmacological properties of amlodipine

Inhibitors of the CYP3A4 isoenzyme

Concomitant use of amlodipine with potent or moderate inhibitors of the CYP3A4 isoenzyme (HIV protease inhibitors, azole antifungal drugs, macrolides, for example, erythromycin or clarithromycin, as well as with verapamil or diltiazem) may be accompanied by a significant increase in systemic exposure to amlodipine. as a result, the risk of a sharp decrease in blood pressure increases.

Clinical manifestations of these variants of simultaneous use may be more pronounced in elderly patients, and medical supervision is necessary in order to possibly adjust the doses of drugs.

Inducers of the CYP3A4 isoenzyme

With simultaneous use of inducers of the CYP3A4 isoenzyme, the concentration of amlodipine may vary. Blood pressure should be monitored, and dose adjustment of amlodipine should be considered during and after concomitant use, especially with strong inducers of the CYP3A4 isoenzyme (for example, rifampicin and St. John’s wort preparations).

Grapefruits and grapefruit juice

The use of amlodipine against the background of eating grapefruit or grapefruit juice is not recommended, since in some patients this may lead to an increase in the bioavailability of the drug and, accordingly, to an increased antihypertensive effect.

Dantrolene (in the form of infusions)

Fatal ventricular fibrillation and cardiovascular collapse associated with hyperkalemia were observed in animals treated with verapamil in combination with intravenous dantrolene. Due to the risk of hyperkalemia, it is recommended to avoid the use of BMCC. such as amlodipine, concomitantly with dantrolen in patients at risk of developing malignant hyperthermia, as well as for the treatment of this condition.

Effect of amlodipine on the pharmacological properties of other drugs

Amlodipine enhances the effect of other antihypertensive drugs.

Atorvastatin, digoxin and warfarin

In clinical drug interaction studies, amlodipine had no effect on the pharmacokinetics of atorvastatin, digoxin, and warfarin.

Cyclosporine

Studies of the interaction of cyclosporine and amlodipine have not been conducted either in healthy volunteers or in any other population, with the exception of patients who have undergone kidney transplantation.

These patients showed an increase in the residual concentrations of cyclosporine in blood plasma (on average by 0-40%).

In patients receiving amlodipine in combination with cyclosporine after a kidney transplant, it is recommended to monitor the concentrations of cyclosporine and, if necessary, reduce its dose.

Simvastatin

When multiple doses of 10 mg amlodipine and 80 mg simvastatin were administered once a day, the systemic exposure of simvastatin was 77% higher than with simvastatin monotherapy. In patients taking amlodipine. the dose of simvastatin should not exceed 20 mg per day.

Tacrolimus

Concomitant use of tacrolimus with amlodipine is characterized by the risk of increasing the concentration of tacrolimus in blood plasma. Patients taking amlodipine should monitor the concentration of tacrolimus in the blood plasma, as well as, if necessary, adjust the dose to avoid toxic effects of tacrolimus.

Other medications

The safety of co-use of amlodipine with thiazide diuretics, beta-blockers, and ACE inhibitors has been established. long-acting nitrates. nitroglycerin (used sublingually), nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, and oral hypoglycemic agents. Concomitant use of amlodipine and sildenafil showed that each of the drugs had an independent antihypertensive effect.

Interaction with telmisartan

Digoxin

With simultaneous use of telmisartan and digoxin, an increase in the median Cmax of digoxin by 49% and its residual concentration by 20% was observed. At the initial stages of taking digoxin, as well as when adjusting its dose and discontinuing treatment, it is necessary to monitor the concentration of the drug in the body to maintain them within the therapeutic range.

Drugs that are not recommended for simultaneous use

Potassium-sparing diuretics and potassium-containing dietary supplements

ARA II drugs, such as telmisartan, reduce the potassium loss caused by diuretics. Potassium-sparing diuretics, in particular spironolactone, eplerenone, triamterene and amiloride. as well as potassium-containing food additives or salt substitutes can cause a significant increase in the content of potassium in the blood plasma.

In cases where the concomitant use of these drugs with telmisartan is required to eliminate confirmed hypokalemia, treatment should be carried out with caution and subject to regular monitoring of the potassium content in the blood plasma.

Lithium preparations

Concomitant use of lithium and ACE or ARA II inhibitors, including telmisartan. It was accompanied by cases of reversible increase in the concentration of lithium in blood plasma and symptoms of toxicity. If the concomitant use of telmisartan with a lithium preparation is necessary, it is recommended to conduct enhanced monitoring of the concentration of lithium in the blood plasma.

Medications that require caution when used concomitantly

Nonsteroidal anti-inflammatory drugs (NSAIDs)

NSAIDs (acetylsalicylic acid in doses that provide anti-inflammatory effects, cyclooxygenase-2 (COX-2) inhibitors and non-selective NSAIDs) may weaken the antihypertensive effect of ARA II. In some patients with impaired renal function (in particular, in patients with dehydration or in elderly patients with reduced renal function), the simultaneous use of ARA II and drugs that suppress COX-2 may lead to an aggravation of impaired renal function, and in some cases to acute renal failure, which is usually reversible.

In this regard, treatment with these drug combinations requires caution, especially in elderly patients. The patient should have a sufficient degree of hydration. Monitoring of renal function is recommended before starting a combination of medications, as well as regularly during treatment.

Ramipril

In a clinical study with the simultaneous use of telmisartan and ramipril, an increase in the AUC0-24 and Cmax values of ramipril and ramiprilat up to 2.5 times was observed. The clinical significance of this observation is unclear. Diuretics (thiazide and loop)

Previous treatment with high doses of diuretics such as furosemide (loop diuretic) and hydrochlorothiazide (thiazide diuretic), as well as restriction of table salt intake, diarrhea, or vomiting may lead to a decrease in BCC and increase the risk of excessive blood pressure reduction at the initial stage of telmisartan therapy.

Medications that require special attention when used simultaneously

Other antihypertensive drugs

The effect of telmisartan may be enhanced with the simultaneous use of other antihypertensive drugs. Double blockade of the renin-angiotensin-aldosterone system (RAAS)

Clinical studies have shown that achieving double blockade of the RAAS with the combined use of ACE inhibitors, ARA II or aliskiren was associated with an increased incidence of adverse events such as decreased blood pressure, hyperkalemia and impaired renal function (including acute renal failure), compared with monotherapy with a drug acting on the RAAS.

Concomitant use of the combination of amlodipine and telmisartan with drugs containing aliskiren is contraindicated in patients with diabetes mellitus and/or moderate or severe renal insufficiency (GFR less than 60 ml/min / 1.73 m2 of body surface area) and is not recommended in other patients.

Concomitant use of the combination of amlodipine and telmisartan with ACE inhibitors is contraindicated in patients with diabetic nephropathy and is not recommended in other patients.

Baclofen and amifostin

Given the pharmacological properties of some drugs (in particular, baclofen and amifostine), it can be predicted that they will potentiate the effect of all antihypertensive drugs, including telmisartan.

Alcohol, barbiturates, narcotic drugs and antidepressants

The risk of developing orthostatic hypotension may increase with alcohol consumption, as well as the use of barbiturates, narcotic drugs or antidepressants.

Glucocorticoids (for systemic use)

Attenuation of the antihypertensive effect of telmisartan.

How to take, course of use and dosage

Inside, once a day, regardless of food intake, with a small amount of liquid.

• Patients receiving amlodipine and telmisartan as separate tablets may be transferred to Telzap ® AM, which contains the same doses of active ingredients.
• Telzap ® AM can be used in patients in whom the use of amlodipine alone or telmisartan alone does not lead to adequate blood pressure control. Patients taking amlodipine at a dose of 10 mg, who have observed adverse reactions that limit the use of the drug, for example, peripheral edema, can switch to taking Telzap ® AM at a dose of 5 mg + 40 mg 1 time per day, which will reduce the dose of amlodipine, but will not reduce the overall expected hypotensive effect.
• Treatment of arterial hypertension in a patient may begin with the use of Telzap ® AM in cases where it is assumed that achieving blood pressure control with any one drug is unlikely. The initial dose of Telzap ® AM is 5 mg + 40 mg once a day. Patients who need a more significant reduction in blood pressure can start taking Telzap ® AM at a dose of 5 mg + 80 mg once a day.

If an additional reduction in blood pressure is required, the dose of the drug can be gradually increased to a maximum of 10 mg + 80 mg, no earlier than 2 weeks after the start of therapy.

Maximum daily dose: 10 mg of amlodipine + 80 mg of telmisartan.

Elderly patients (over 65 years of age): no dose adjustment is required.

Patients with impaired renal function

No dose adjustment is required in patients with mild to moderate renal impairment. Experience with the drug in patients with severe renal impairment or undergoing hemodialysis is limited. In this category of patients, treatment with Telzap ® AM should be carried out with caution, since amlodipine and telmisartan are not eliminated from the body by hemodialysis.

Patients with impaired liver function

Caution should be exercised when selecting the dose of Telzap® AM in patients with mild or moderate hepatic impairment. The daily dose of telmisartan should not exceed 40 mg. Telzap ® AM is contraindicated in patients with severe hepatic impairment.

Children and teenagers

The use of Telzap® AM in patients under 18 years of age is contraindicated due to the lack of sufficient data on the safety and efficacy of the drug in this age group.

Overdose

Symptoms of overdose in the combination of amlodipine + telmisartan have not been reported. Possible symptoms of overdose consist of symptoms from the individual components of the drug. Overdose of amlodipine can lead to excessive peripheral vasodilation and reflex tachycardia. A marked and persistent decrease in blood pressure, including shock and death, has been reported. The most pronounced symptoms of telmisartan overdose were a decrease in blood pressure and tachycardia. Clinical manifestations such as bradycardia, dizziness, increased plasma creatinine, and acute renal failure were also reported. Treatment The patient should be under close clinical supervision. Treatment should include symptomatic and supportive therapy. The set of treatment measures depends on the length of time since taking the drug and the severity of symptoms. Recommended measures include inducing vomiting and / or gastric lavage, and taking activated charcoal. Regular monitoring of the concentration of electrolytes and creatinine in the blood plasma should be carried out. If blood pressure decreases, the patient should be placed in a supine position with the lower extremities raised, and immediately begin the use of saline and other plasma-substituting solutions to replenish the BCC. Restoration of vascular tone and normalization of blood pressure can be achieved by introducing vasoconstrictors, provided that there are no contraindications to their use. Intravenous use of calcium gluconate may provide relief from symptoms associated with calcium channel blockage. Amlodipine and telmisartan are practically not eliminated from the body by hemodialysis.

Special instructions

Amlodipine

Patients with chronic heart failure

In a long-term placebo-controlled trial (PRAISE-2) in patients with NYHA functional class III-IV CHF of non-ischemic etiology, the use of amlodipine was associated with an increase in reports of pulmonary edema, despite the absence of a significant difference in the incidence of heart failure progression compared to placebo.

BMCC, including amlodipine, should be used with caution in patients with CHF due to the possible risk of other cardiovascular complications and mortality.

Liver function disorders

As with other BMCs, the T%^%1/2 of amlodipine increases in patients with impaired liver function. Therefore, Telzap ® AM should be used with caution in such patients, and the dose of telmisartan should not exceed 40 mg once a day. Telzap ® AM is contraindicated in patients with severe hepatic impairment.

Impaired renal function

In patients with impaired renal function, amlodipine can be used in normal doses. Changes in amlodipine plasma concentrations did not correlate with the severity of renal impairment. Amlodipine is not eliminated from the body during dialysis.

Elderly patients

No dose adjustment of Telzap ® AM is required in elderly patients.Increasing the dose should be done with caution.

Children

The safety and efficacy of Telzap® AM in children have not yet been established.

Sorbitol

This medicinal product contains sorbitol (E 420). Telzap ® AM is contraindicated in patients with rare hereditary problems of fructose intolerance.

Telmisartan

Impaired liver function

The combination of amlodipine + telmisartan is contraindicated in patients with cholestasis, biliary tract obstruction, and / or severe hepatic impairment, as telmisartan is mainly excreted in the bile. There is reason to believe that these patients have reduced hepatic clearance of telmisartan. The drug should be used with caution in patients with mild to moderate hepatic impairment.

Renovascular hypertension

Patients with bilateral renal artery stenosis or stenosis of the artery to a single functioning kidney are at increased risk of significantly lowering blood pressure and developing acute renal failure when treated with drugs acting on the RAAS.

Impaired kidney function and kidney transplantation

When using telmisartan in patients with impaired renal function, it is recommended to periodically monitor the content of potassium and creatinine in blood plasma. There is no experience of using the drug in patients who underwent kidney transplantation shortly before use. Telmisartan is not eliminated by dialysis.

Decreased circulating blood volume (BCC)

Reduction of blood pressure. especially after the first use of Telzap ® AM, it may occur in patients with a reduced BCC and / or low blood sodium content against the background of previous diuretic treatment, restriction of salt intake, diarrhea or vomiting. Such conditions (fluid and/or sodium deficiency) should be corrected before starting Telzap ® AM.

Double blockade of the RAAS

Data on the concomitant use of ACE inhibitors with ARA II or with drugs containing aliskiren confirm an increased risk of a sharp decrease in blood pressure, hyperkalemia, and decreased renal function (including acute renal failure).

Concomitant use of ARA II with drugs containing aliskiren is contraindicated in patients with diabetes mellitus and/or moderate or severe renal insufficiency (GFR less than 60 ml/min / 1.73 m2 of body surface area) and is not recommended in other patients. If it is necessary to implement a double blockade of the RAAS, each case should be considered individually and renal function, water-electrolyte balance and blood pressure indicators should be carefully monitored.

Concomitant use of ARA II with ACE inhibitors is contraindicated in patients with diabetic nephropathy and is not recommended in other patients.

Hypotension, syncope, hyperkalemia, and impaired renal function (including acute renal failure) have been reported with RAAS blockade in predisposed patients, especially with concomitant use of medications acting on the RAAS.

In this regard, double blockade of the RAAS (in particular, with the simultaneous use of telmisartan with other RAAS blockers) is not recommended. Renal function should be carefully monitored if multiple RAAS blockers are required at the same time.

Other conditions associated with RAAS stimulation

In patients whose vascular tone and renal function depend primarily on the activity of the RAAS (for example, patients with severe chronic heart failure or existing kidney disease, including renal artery stenosis), the use of drugs acting on this system, such as telmisartan. It is associated with an acute decrease in blood pressure, hyperazotemia, oliguria, or rarely with the development of acute renal failure.

Primary hyperaldosteronism

In patients with primary hyperaldosteronism, treatment with antihypertensive drugs, the effect of which is carried out by inhibiting the RAAS, is usually ineffective. Therefore, the use of Telzap ® AM is not recommended.

Aortic or mitral valve stenosis, obstructive hypertrophic cardiomyopathy

As with other vasodilators, special care should be taken in patients with aortic or mitral stenosis, as well as hypertrophic obstructive cardiomyopathy.

Patients with diabetes mellitus receiving insulin or other hypoglycemic medications

In patients with diabetes mellitus who are taking insulin or other hypoglycemic drugs, the use of telmisartan may lead to the development of hypoglycemia and should be accompanied by monitoring of blood glucose levels. If necessary, the dose of insulin or other hypoglycemic drugs should be adjusted.

Hyperkalemia

As with other drugs acting on the RAAS, the use of telmisartan may contribute to the development of hyperkalemia.

In elderly patients, patients with renal insufficiency or diabetes mellitus, as well as in patients who are simultaneously receiving treatment with other drugs that increase the content of potassium in the blood plasma, or have concomitant pathological conditions, hyperkalemia can be a cause of death.

When concomitant use of drugs acting on the RAAS should carefully evaluate the benefit-risk ratio.

The main risk factors for hyperkalemia include:

• diabetes mellitus, impaired renal function, elderly (patients over 70 years of age•;

* concomitant use with drugs acting on the RAAS, and/or supplements containing potassium.

Medications that may cause hyperkalemia. These include potassium-containing salt substitutes, potassium-sparing diuretics, ACE inhibitors, ARA II, NSAIDs, including selective COX-2 inhibitors, heparin, immunosuppressants (cyclosporine and tacrolimus) and trimethoprim.

* concomitant diseases, especially dehydration, acute heart failure, metabolic acidosis, acute renal failure (for example, in infectious diseases), cytolysis syndrome (for example, acute limb ischemia, rhabdomyolysis, extensive trauma).

Patients at risk are advised to carefully monitor the potassium content in the blood plasma. Ethnic differences

Like all other ARA II drugs, telmisartan is less effective in reducing blood pressure in black patients than in other races, possibly due to a greater predisposition to a decrease in renin activity in the population of these patients.

Coronary heart disease and cerebrovascular disease

As with any other antihypertensive medication, excessive lowering of blood pressure in patients with coronary heart disease or cerebrovascular disease can lead to the development of myocardial infarction or stroke.

Influence on the ability to drive vehicles and mechanisms

Telzap ® AM has a moderate effect on the ability to drive vehicles and control moving mechanisms. Due to the possible development of dizziness, headache, fatigue, nausea when taking the drug, care should be taken when driving vehicles and engaging in other activities that require concentration of attention and speed of psychomotor functions.

If the described adverse reactions occur, you should refrain from performing these activities.
