Indications to use

Koraksan's use is shown at therapy of stable stenocardia at patients with a normal sinoatrial rate:

  • Existence of contraindications to beta adrenoblockers or at their intolerance;
  • Inadequate control of stable stenocardia at optimum doses of beta adrenoblockers, for a combination with beta adrenoblockers.

Besides, drug is appointed at chronic heart failure at patients with the heart rate (HR) of 70 and more beats per minute and a sinoatrial rate for the purpose of reduction of frequency of development of possible cardiovascular complications.

Contraindications

  • Sinuatrial blockade;
  • Bradycardia, at ChSS at rest less than 60 beats per minute;
  • Acute myocardial infarction;
  • Unstable stenocardia;
  • Cardiogenic shock;
  • Heavy arterial hypotension (the systolic arterial pressure (AP) below 90 mm of a mercury column (hg) and diastolic is lower than the ABP 50 mm hg);
  • Sick Sinus Syndrome (SSS);
  • Acute or unstable heart failure;
  • Atrioventricular block (AV blockade) of the III degree;
  • Continuous stimulation by an artificial pacemaker of heart;
  • Concomitant use of strong inhibitors of isoenzymes of system of P450 3A4 cytochrome, such, as нефазодон, antibiotics of group of macroleads (телитромицин, кларитромицин, джозамицин, peroral erythromycin), antifungal drugs of group of azoles (итраконазол, кетоконазол), HIV protease inhibitors (ритонавир, нелфинавир);
  • The expressed liver failure (on a scale of Chayld-Pyyu more than 9 points);
  • Glucose galactose sprue, lactose intolerance, deficit of lactase;
  • Period of pregnancy and breastfeeding;
  • Age up to 18 years;
  • Hypersensitivity to drug components.

Drug is contraindicated to the women of reproductive age who are not applying well-tried remedies of contraception.

With care Koraksan sick with arterial hypotension, AV blockade of the II degree, chronic heart failure of the IV class (NYHA classification), a moderate form of the liver failure expressed by a renal failure (is recommended to appoint at the clearance of creatinine (CC) less than 15 ml/min.), inborn lengthening of an interval of QT, recently had stroke, a pigmental degeneration of a retina.

Under careful medical control it is necessary to accept drug at a combination to moderate inhibitors and inductors of isoenzymes CYP3A4, medicines extending QT interval, grapefruit juice, blockers of the slow calcium channels reducing ChSS (diltiazem, verapamil), nekaliysberegayushchy diuretics.

Route of administration and dosage

Pill is taken inside, during food, 2 times a day (in the morning and in the evening).

At stable stenocardia the initial daily dose makes 10 mg (on 1 tablet of 5 mg in the morning and in the evening). On the basis of clinical indications, in 3-4 weeks of reception the daily dose can be brought to 15 mg. In case of decrease in ChSS at rest to less than 50 beats per minute or emergence of symptoms of bradycardia (dizziness, strong decrease in the ABP, increased fatigue), the daily dose of drug needs to be lowered to 5 mg. In the absence of therapeutic effect after a dose decline use of drug should be cancelled.

At chronic heart failure the recommended initial daily dose – 10 mg. In 2 weeks of use if ChSS at rest keeps stability at the level of more than 60 beats per minute, the dose can be raised to 15 mg.

Correction of a daily dose of Koraksan depends on stability at the patient of ChSS at rest:

  • 50 beats per minute and less – 5 mg (against the background of emergence of symptoms of bradycardia);
  • From 50 to 60 beats per minute – 10 mg;
  • It is higher than 60 beats per minute – 15 mg.

If ChSS of 50 beats per minute and less or bradycardia symptoms at the patient remain, it is necessary to consider a question of drug withdrawal.

To patients at the age of 75 years the recommended initial daily dose is also more senior makes 5 mg, its perhaps further increase.

Patients with an impaired renal function (KK more than 15 ml/min.) are recommended to appoint an initial daily dose of 10 mg, in case of therapeutic effect its increase up to 15 mg is possible in 3-4 weeks of administration of drug.

Correction of the usual recommended dosing is not required to patients with easy degree of a liver failure (to 7 points on a scale of Chayld-Pyyu).

At the expressed renal failure and moderate degree of a liver failure it is recommended to appoint drug with care.

Side effects

Koraksan's use can cause side effects:

  • From cardiovascular system: often – bradycardia; infrequently – supraventricular premature ventricular contraction, a heart consciousness; very seldom – SSSU, fibrillation of auricles, AV blockade of II and III degrees; frequency is unknown – the expressed decrease in the ABP (it can be connected with bradycardia);
  • From sense bodys: very often – changes a svetovospriyatiya (photopsia); often – a sight illegibility; infrequently – вертиго; frequency is unknown – a vision disorder, a diplopia;
  • From the alimentary system: infrequently – nausea, diarrhea or a lock;
  • From respiratory system: infrequently – an asthma;
  • From a nervous system: often – a headache (especially the first 4 weeks of therapy), dizziness; frequency is unknown – a syncope;
  • From a musculoskeletal system: infrequently – spasms of muscles;
  • From integuments and a hypodermic fatty tissue: frequency is unknown – an itch, skin rash, an erythema, a small tortoiseshell, a Quincke's disease;
  • From laboratory and tool indicators: infrequently – an eosinophilia, a hyperuricemia, lengthening of an interval of QT on the electrocardiogram (ECG), increase in level of concentration of creatinine in blood;
  • General frustration: frequency is unknown – increased fatigue, an adynamy, an indisposition.

The most often undesirable effects of reception of an ivabradin have dozozavisimy character and are connected with the mechanism of clinical effect of drug.

Special instructions

Koraksan has no clinical effect at treatment or prevention of arrhythmias, against the background of supraventricular or ventricular tachycardia its effect falls.

Purpose of an ivabradin is not recommended to patients with fibrillation of auricles (ciliary arrhythmia) and other types of arrhythmias, caused by dysfunction of a sinus node.

The patients with chronic heart failure accepting drug and patients with other diseases – against the background of simultaneous use with Amiodaronum or antiarrhytmic drugs I of a class are more subject to risk of development of fibrillation of auricles. Use of drug for patients with disturbances of intra ventricular conductivity (blockade of the left or right leg of a ventriculonector), chronic heart failure and a ventricular dissinkhroniya has to take place under fixed control of the doctor.

At bradycardia with ChSS at rest less than 60 beats per minute, and directly after a stroke purpose of drug is contraindicated to unstable heart failure.

At emergence of disturbances of visual functions, it is necessary to consult with the doctor.

In need of purpose of drug the patient with an inborn syndrome of the extended QT interval treatment has to take place under strict control of an ECG.

At patients with fibrillation of auricles the risk of development of the expressed bradycardia at pharmacological cardioversion of recovery of a sinoatrial rate is not confirmed. In 24 hours prior to carrying out planned electric cardioversion it is necessary to stop Koraksan's reception.

Change of hypotensive therapy at chronic heart failure at the patients accepting Koraksan has to take place under monitoring of the ABP.

Drug does not exert impact on ability of the patient to control of vehicles and mechanisms, however, it is necessary to consider a possible vision disorder in the form of temporary change a svetovospriyatiya and to be careful during sharp change of intensity of light, preferential at night.

Medicinal interaction

Combinations with inductors and inhibitors of an isoenzyme CYP3A4 as they cause decrease and increase (according to) the level of concentration of an ivabradin in a blood plasma are not recommended.

Koraksan's combination to strong inhibitors of an isoenzyme CYP3A4 as they can cause increase in average concentration of an ivabradin in a blood plasma by 7-8 times is contraindicated.

The accompanying purpose of a flukonazol and other moderate inhibitors of an isoenzyme CYP3A4 is possible if ChSS at rest exceeds 60 beats per minute. The initial dose of drug is recommended of 5 mg a day, treatment needs to be accompanied with control of ChSS.

Additional lengthening of an interval of QT causes a combination of an ivabradin to Disopyramidum, quinidine, bepridily, ibutilidy, sotaloly, Amiodaronum and other antiaritmika; ziprazidony, Pimozidum, sertindoly, tsizapridy, galofantriny, pentamidine, meflokhiny, erythromycin (at intravenous administration). Treatment in this combination needs to be carried out under careful and regular control of an ECG.

Increase in risk of development of arrhythmia can be promoted by a hypopotassemia therefore with care it is necessary to appoint drug at a concomitant use of nekaliysberegayushchy diuretics (loopback and thiazide diuretics).

Combined use of rifampicin, barbiturates, Phenytoinums, the vegetable means including a St. John's Wort of the made a hole or other inductors of an isoenzyme CYP3A4 can reduce concentration and action of an ivabradin.

There is no clinically significant influence on pharmacokinetics and a pharmacodynamics of drug from a combination to warfarin, digoxin, inhibitors of a protonew pomp (лансопразол, омепразол), GMG-KOA-reduktazy inhibitors (симвастатин), FDE5 inhibitors (sildenafit), blockers of slow calcium channels derivatives of a dihydropyridinic row (лацидипин, амлодипин).

Koraksan does not influence pharmacokinetics of an amlodipin, warfarin, digoxin, a simvastatin, latsidipin and a pharmacodynamics of warfarin, digoxin, acetylsalicylic acid.

Grapefruit juice increases concentration of an ivabradin in a blood plasma twice therefore during treatment it is recommended to avoid its use.

Use of drug in a combination with antagonists of receptors of angiotensin II, APF inhibitors, beta adrenoblockers, antagonists of Aldosteronum, diuretics, nitrates of the prolonged and short action, a fibratama, GMG-KOA-reduktazy inhibitors, inhibitors of a proton pomp, hypoglycemic means for intake, antiagregantny drugs is shown.
