Pharmacological properties:

Pharmacodynamics. Bisoprolol - the selection a beta 1 adrenoblocker, without own sympathomimetic activity, does not possess membrane stabilizing action. As well as for other beta1-adrenoblockers, the action mechanism at arterial hypertension is not clear. At the same time, it is known what бисопролол reduces activity of a renin in a blood plasma, reduces the need of a myocardium for oxygen, urezhat the heart rate (HR). Has hypotensive, antiarrhytmic and anti-anginal effect.
Blocking in low doses a beta 1 adrenoceptors of heart, reduces stimulated catecholamines formation of cyclic adenosinemonophosphate (tsAMF) from adenosinetriphosphate (ATP), reduces intracellular current of calcium ions, oppresses all functions of heart, reduces atrioventricular (AV) conductivity and excitability. At exceeding of a therapeutic dose has beta2-adrenoceptor blocking effect. The general peripheric vascular resistance at the beginning of drug use, in the first 24 h, increases (as a result of reciprocal increase of activity of alpha adrenoceptors and elimination of stimulation of beta2-adrenoceptors), in 1-3 days is returned to a reference value, and at prolonged use - decreases.
The anti-hypertensive effect is connected with reduction of minute volume of blood, sympathetic stimulation of peripheral vessels, decrease of the activity of sympathoadrenal system (SAS) (is of great importance for patients with initial hypersecretion of a renin), recovery of sensitivity in response to a lowering of arterial pressure (ABP) and influence on the central nervous system (CNS). At arterial hypertension the effect develops in 2-5 days, stable action is noted in 1-2 months.
The anti-anginal effect is caused by reduction of need of a myocardium for oxygen as a result of decrease in contractility and other functions of a myocardium, lengthening of a diastole, improvement of perfusion of a myocardium. Due to increase in end diastolic pressure in a left ventricle and increases in stretching of muscle fibers of ventricles oxygen requirement, especially at patients with the chronic heart failure (CHF) can increase.
At use in average therapeutic doses, unlike non-selective beta adrenoblockers, exerts less expressed impact on the bodies containing beta2-adrenoceptors (a pancreas, skeletal muscles, smooth muscles of peripheral arteries, bronchial tubes and a uterus) and on carbohydrate metabolism; does not cause a delay of ions of sodium in an organism; expressiveness of atherogenous action does not differ from effect of propranolol.

Pharmacokinetics. Bisoprolol is almost completely soaked up in digestive tract, meal does not influence absorption. The effect of "the first passing" through a liver is insignificant that results in high bioavailability (90%).
Bisoprolol is metabolized on an oxidizing way without the subsequent conjugation. All metabolites have strong polarity and are removed by kidneys. The main metabolites found in a blood plasma and urine do not show pharmacological activity. The data obtained as a result of experiments with microsomes of a liver of the person of in vitro show what бисопролол is metabolized first of all by means of CYP3A4 isoenzyme (about 95%), and the isoenzyme of CYP2D6 plays only a small role.
Communication with proteins of a blood plasma about 30%. Distribution volume - 3,5 l/kg. The general clearance - about 15 l/h. The maximum concentration in a blood plasma is defined in 2-3 hours. Permeability through a blood-brain barrier and a placental barrier - low.
Plasma elimination half-life of blood (10-12 hours) provides efficiency within 24 hours after reception of a single daily dose.
Bisoprolol is brought from an organism in two ways, 50% of a dose are metabolized in a liver with formation of inactive metabolites. About 98% are removed by kidneys, 50% are brought out of them in not changed look; less than 2% - through intestines (with bile).
As removal takes place in kidneys and in a liver equally, with an abnormal liver function or with a renal failure of dose adjustment it is not required to patients. The pharmacokinetics of a bisoprolol is linear and does not depend on age.
At patients with HSN plasma concentration of a bisoprolol are higher, and the elimination half-life is more long in comparison with healthy volunteers.

Indications to use:

- Arterial hypertension;
- coronary heart disease: prevention of attacks of stable stenocardia.

Route of administration and doses:

Drug Bisoprolol - Tev is accepted inside, in the morning on an empty stomach, 1 time a day with a small amount of liquid, in the morning till a breakfast, in time or after it. Tablets should not be chewed or pounded in powder.
In all cases the mode of reception and a dose are selected by the doctor to each patient individually, in particular, considering ChSS and a condition of the patient. At arterial hypertension and coronary heart disease drug is appointed on 5 mg of 1 times a day. If necessary the dose is increased to 10 mg of 1 times a day. At treatment of arterial hypertension and stenocardia the maximum daily dose makes 20 mg of 1 times/days.
For patients with the expressed renal failures (KK less than 20 ml/min.) or with the expressed abnormal liver functions the maximum daily dose makes - 10 mg of 1 times a day. Increase in a dose at such patients needs to be carried out with extra care. Dose adjustment is not required from elderly patients.

Features of use:

Control of a condition of the patients accepting drug Bisoprolol - Teva, has to include measurement of ChSS and the ABP, carrying out an ECG, definition of concentration of glucose of blood at patients with a diabetes mellitus (1 time in 4-5 months). At patients of advanced age it is recommended to monitor function of kidneys (1 times in 4-5 months).
It is necessary to train the patient in a technique of calculation of ChSS and to instruct about need of medical consultation at ChSS less than 50 beats/min.
Before an initiation of treatment it is recommended to conduct a research of function of external respiration at patients with the burdened bronchopulmonary anamnesis.
The patients using contact lenses should consider that against the background of treatment by drug reduction of products of the lacrimal liquid is possible.
At drug use Bisoprolol - Teva with a pheochromocytoma is available for patients risk of development of paradoxical arterial hypertension (if effective blockade of alpha adrenoceptors is previously not reached).
At a thyrotoxicosis бисопролол can mask certain clinical signs of a thyrotoxicosis (for example, tachycardia). Sharp drug withdrawal at patients with a thyrotoxicosis is contraindicated as it is capable to strengthen symptomatology.
At a diabetes mellitus can mask the tachycardia caused by a hypoglycemia. Unlike non-selective beta adrenoblockers practically does not strengthen the hypoglycemia caused by insulin and recovery of concentration of glucose in blood to normal value does not detain.
At simultaneous use of a clonidine its reception can be stopped only in several days after drug withdrawal Bisoprolol - Teva. Strengthening of expressiveness of hypersensitivity reaction and lack of effect of usual doses of Epinephrinum against the background of the burdened allergological anamnesis is possible.
In case of need performing planned surgical treatment drug should be cancelled for 48 h before carrying out the general anesthesia. If the patient accepted drug before surgical intervention, it should pick up medicine for the general anesthesia with minimum negative inotropic effect.
Reciprocal activation of a vagus nerve can be eliminated with intravenous administration of atropine (1-2 mg).
Medicines which exhaust depot of catecholamines (including Reserpinum) can strengthen effect of beta adrenoblockers therefore the patients accepting such combinations of medicines have to be under constant observation of the doctor regarding identification of the expressed decrease in the ABP or bradycardia.
Patients with bronkhospastichesky diseases can appoint with care cardioselective beta adrenoblockers in case of intolerance and/or inefficiency of other antihypertensives. Against the background of reception of beta adrenoblockers at patients with the accompanying bronchial asthma resistance of respiratory tracts can amplify. At exceeding of a dose of drug Bisoprolol - Teva at such patients arises danger of development of a bronchospasm. In case of identification at patients of the accruing bradycardia (ChSS less than 50 уд. / min.), the expressed decrease in the ABP (systolic the ABP less than 100 mm hg), AV of blockade, it is necessary to reduce a dose or to stop treatment. Bisoprolol - Teva is recommended to stop therapy by drug at development of a depression.
It is impossible to interrupt sharply treatment because of danger of development of heavy arrhythmias and a myocardial infarction. Drug withdrawal is carried out gradually, reducing a dose within 2 weeks and more (lower a dose by 25% in 3-4 days).
It is necessary to cancel drug before a concentration research in blood and urine of catecholamines, a normetanefrina, vanilinmindalny acid, credits of antinuclear antibodies.
At smokers efficiency of beta adrenoblockers is lower.
Influence on ability to manage vehicles and to work with the equipment demanding the increased concentration of attention
 Drug use Bisoprolol - Teva does not influence ability to manage vehicles according to results of a research at patients with an ischemic heart disease. However owing to individual reactions ability to manage vehicles or work with technically difficult mechanisms can be broken. On it it is necessary to pay special attention in an initiation of treatment, after change of a dose, and also at simultaneous alcohol intake.

Side effects:

Frequency of the side reactions given below was defined according to the following (classification of World Health Organization): very often - not less than 10%; often - not less than 1%, but less than 10%; infrequently - not less than 0,1%, but less than 1%; seldom - not less than 0,01%, but less than 0,1%; very seldom - less than 0,01%, including separate messages.
From heart and vessels: very often - urezheny ChSS (bradycardia, especially at patients with HSN); the heart consciousness, is frequent - the expressed decrease in the ABP (especially at patients with HSN), manifestation of a vasomotor spasm (strengthening of disturbances of peripheric circulation, a cryesthesia in extremities (paresthesia); infrequently - disturbance of AV of conductivity (up to development of total cross block and a cardiac standstill), arrhythmias, orthostatic hypotension, aggravation of a current of HSN with development of peripheral hypostases (puffiness of anklebones, feet; asthma), stethalgia.
From a nervous system: often - dizziness headache, an adynamy, increased fatigue, sleep disorders, a depression, concern; seldom - confusion of consciousness or short-term loss of memory, "dreadful" dreams, hallucinations, a myasthenia, a tremor, myotonia. Usually these phenomena have easy temper and pass, as a rule, within 1-2 weeks, after an initiation of treatment.
From sense bodys: seldom - a vision disorder, reduction of a slezootdeleniye (it is necessary to consider when carrying contact lenses), a sonitus, decrease in hearing, ear pain; very seldom - dryness and morbidity of eyes, conjunctivitis, taste disturbances.
From respiratory system: infrequently - a bronchospasm at patients with bronchial asthma or obstructive respiratory diseases; seldom - allergic rhinitis; nose congestion.
From the alimentary system: often - nausea, vomiting, diarrhea, a lock, dryness of a mucous membrane of an oral cavity, an abdominal pain; seldom - hepatitis, increase in activity of enzymes of a liver (alaninaminotranspherase, aspartate aminotransferase), increase in concentration of bilirubin, taste change.
From a musculoskeletal system: infrequently - an arthralgia, a dorsodynia.
From urinogenital system: very seldom - disturbance of a potentiality, weakening of a libido.
Laboratory indicators: seldom - increase in concentration of triglycerides in blood; in some cases - thrombocytopenia, an agranulocytosis, a leukopenia.
Allergic reactions: seldom - a skin itch, rash, a small tortoiseshell
From integuments: seldom - sweating strengthening, a dermahemia, a dieback, psoriazopodobny skin reactions; very seldom - the alopecia, beta adrenoblockers can aggravate the course of psoriasis.
Others: syndrome of "cancellation" (increase of attacks of stenocardia, increase in the ABP).

Interaction with other medicines:

Simultaneous use of other medicines can affect efficiency and portability of medicines. Such interaction can happen also when two medicines are accepted through a short period. The doctor needs to be informed on use of other medicines even if use is carried out without instruction.
Antiarrhytmic means of the I class (for example, quinidine, Disopyramidum, lidocaine, Phenytoinum; флекаинид, пропафенон) at simultaneous use with bisoprololy can reduce AV conductivity and sokratitelny ability of a myocardium.
Antiaritmicheksy means of the III class (for example, Amiodaronum) can strengthen disturbance of AV of conductivity.
Effect of beta adrenoblockers for topical administration (for example, eye drops for treatment of glaucoma) can strengthen system effects of a bisoprolol (decrease in the ABP, urezheny ChSS).
Parasimpatomimetiky at simultaneous use with bisoprololy can strengthen disturbance of AV of conductivity and increase risk of development of bradycardia. Simultaneous use of drug Bisoprolol - Teva with beta-adrenergic agonists (for example, изопреналин, Dobutaminum) can lead to decrease in effect of both drugs.
The combination of a bisoprolol to the adrenomimetika influencing on beta and alpha adrenoceptors (for example, Norepinephrinum, Epinephrinum), can strengthen vasopressor effects of these means arising with participation of alpha adrenoceptors, leading to increase in the ABP. Similar interactions are more probable at use of non-selective beta adrenoblockers. Meflokhin at simultaneous use with bisoprololy can increase risk of development of bradycardia.
The allergens used for an immunotherapy or extracts of allergens for skin tests increase risk of emergence of heavy system allergic reactions or an anaphylaxis at the patients receiving бисопролол. The iodocontaining X-ray contrast diagnostic intravenous agents increase risk of development of anaphylactic reactions. Phenytoinum at intravenous administration, means for inhalation anesthesia (derivatives of hydrocarbons) increase expressiveness of cardiodepressive action and probability of decrease in the ABP.
Efficiency of insulin and hypoglycemic means for intake can change at treatment bisoprololy (masks symptoms of the developing hypoglycemia: tachycardia, increase in the ABP).
The clearance of lidocaine and xanthines (except theophylline) can decrease in connection with possible increase in their concentration in a blood plasma, especially at patients with initially increased clearance of theophylline under the influence of smoking. Hypotensive effect non-steroidal anti-inflammatory drugs (NPVP) (a delay of ions of sodium and blockade of synthesis of prostaglandins kidneys) weaken, glucocorticosteroids and estrogen (a delay of ions of sodium). Cardiac glycosides, Methyldopum, Reserpinum and гуанфацин, blockers of "slow" calcium channels (verapamil, diltiazem), Amiodaronum and other antiarrhytmic means increase risk of development or aggravation of bradycardia, AV of blockade, a cardiac standstill and heart failure. Nifedipine can lead to considerable decrease in the ABP. Diuretics, a clonidine, sympatholytics, гидралазин and other antihypertensives can lead to excessive decrease in the ABP.
Action of not depolarizing muscle relaxants and anticoagulating effect of coumarins during treatment бисопролол ohm can be extended. Tricyclic and tetracyclic antidepressants, antipsychotic means (neuroleptics), ethanol, sedative and hypnagogues strengthen oppression of the central nervous system.
Simultaneous use with MAO inhibitors owing to considerable strengthening of hypotensive action is not recommended. Having rummaged in treatment between reception of MAO inhibitors and a bisoprolola has to make not less than 14 days. Not hydrogenated alkaloids of an ergot increase risk of development of disturbances of peripheric circulation.
Ergotamine increases risk of development of disturbance of peripheric circulation. Sulfasalazinum increases concentration of a bisoprolol in a blood plasma. Rifampicin shortens an elimination half-life of a bisoprolol.

With care
 Psoriasis, depression (including in the anamnesis), a diabetes mellitus (can mask hypoglycemia symptoms), allergic reactions (in the anamnesis), a bronchospasm (in the anamnesis), performing the desensibilizing therapy, Printsmetal's stenocardia, AV blockade of the I degree, the expressed renal failures (the clearance of creatinine (CC) less than 20 ml/min.); the expressed abnormal liver functions; thyrotoxicosis, advanced age.

Use at pregnancy and during breastfeeding
Pregnancy
 Bisoprolol does not render direct cytotoxic, mutagen and teratogenic action, but has pharmacological effects which can make harmful effects on the course of pregnancy and/or on a fruit, or the newborn. Usually beta adrenoblockers reduce placental perfusion that leads to delay of growth of a fruit, pre-natal death of a fruit, abortions or premature births. The fruit and the newborn child can have pathological reactions, such as a pre-natal arrest of development, a hypoglycemia, bradycardia.
Bisoprolol - Tev should not be applied during pregnancy, use is possible if the advantage for mother exceeds risk of development of side effects in a fruit and/or the child. In that case when treatment by drug Bisoprolol - Teva is considered as necessary, it is necessary to trace a blood stream in a placenta and a uterus, and also to watch growth and development of future child, and in case of the undesirable phenomena concerning pregnancy and/or a fruit, to accept alternative methods of therapy. It is necessary to inspect carefully the newborn after the delivery. Symptoms of a hypoglycemia and bradycardia, as a rule, arise during the first 3 days of life.
Breastfeeding period
 There are no data on penetration of a bisoprolol into breast milk. Therefore administration of drug Bisoprolol - Teva is not recommended to women during feeding by a breast.
In need of use of drug in the period of a lactation, breastfeeding needs to be stopped.

Overdose:

Symptoms: arrhythmia, ventricular premature ventricular contraction, the expressed bradycardia, AV blockade, the expressed decrease in the ABP, an acute heart failure, a hypoglycemia, a Crocq's disease, breath difficulty, a bronchospasm, dizziness, a syncope, spasms.
Treatment: at overdose emergence, first of all it is necessary to stop administration of drug, to carry out a gastric lavage, to appoint the adsorbing means, to carry out symptomatic therapy.
At the expressed bradycardia - intravenous administration of atropine. If effect insufficient, with care it is possible to enter the means possessing positive chronotropic action. Temporary statement of an artificial pacemaker can sometimes be required.
At the expressed decrease in the ABP - intravenous administration of plasma substituting solutions and vazopressor.
At a hypoglycemia intravenous administration of a glucagon or intravenous administration of a dextrose (glucose) can be shown.
At AV to blockade: patients have to be under constant observation and receive treatment by beta-adrenergic agonists, such as Epinephrinum. In case of need - statement of an artificial pacemaker.
