Talliton: pharmachologic effect

Alpha1– and beta1-, beta2-adrenoblokator. The drug is a non-selective beta-blocker with vasodilating action (by blocking α1-adrenoreceptorov), and also possesses antioxidant activity. Talliton active substance is a mixture of two enantiomers of racemic carvedilol.

Carvedilol reduces round, ugnetaet renin-angiotensin-alydosteronovuyu sistemu. Reduces the activity of renin in blood plasma, therefore, when applied practically not observed water retention.

Karvedilol, Being competitive β-adrenergic blocker, It has a negative chrono, ʙatmo- and inotropic effect. The drug slows conduction in AV-node. Carvedilol has no intrinsic sympathomimetic activity, It has a membrane-stabilizing effect.

The set vasodilator and beta-adrenoceptor blocking properties of carvedilol manifests the following clinical effects.

The appointment of the drug is not accompanied by an increase in systemic vascular resistance (as in the case with other beta-blockers). Carvedilol significantly reduces the heart rate, However, renal perfusion and function remain unchanged. As well as PR does not change, the feeling of cold extremities when using carvedilol is rare (in contrast to the use of beta-blockers without vasodilating activity).

The antihypertensive effect develops in 2-3 h after a single application and lasts for 24 no. In long-term treatment of the maximum effect observed after 3-4 of the week.

In CHD carvedilol has antianginal, which is stored in the long-term treatment. Studies have shown hemodynamic, Carvedilol reduces pre- and afterload on the heart.

The beneficial effect of carvedilol on hemodynamics of the heart, Left ventricular ejection fraction was observed as in dilated cardiomyopathy, and in the form of ischemic heart disease. In heart failure, carvedilol reduces end-systolic and end-diastolic volume, as well as peripheral and pulmonary vascular resistance. Ejection fraction and cardiac index in the normal function of the heart do not change.

In the case of left ventricular dysfunction alpha1-adrenoceptor blocking effect of carvedilol leads to arterial and expansion, less, veins. In clinical studies it has been found, that the supplemental taken against the background of cardiac glycosides, ACE inhibitors and diuretics, carvedilol reduces mortality, It slows the progression of the disease and improves the general condition of the patient regardless of the severity of the disease.

During treatment with carvedilol ratio of HDL-C / LDL-C is not changed.

Talliton: pharmacokinetics

Absorption

After oral administration, carvedilol is rapidly absorbed from the gastrointestinal tract. Metabolized in the “first pass” through the liver. Bioavailability is about 25%. Cmax achieved through 1 hours after oral administration.

Pharmacokinetics carvedilol is linear (plasma concentration is proportional to the dose). Concomitant food has no effect on the bioavailability and carvedilol value Cmax plasma, but can increase the time to reach Cmax.

Distribution

Carvedilol is lipophilic compound. Plasma protein binding - 98-99%. In Кажущийсяd approximately 2 l / kg.

Carvedilol and its metabolites can cross the placental barrier, and are excreted in breast milk.

Metabolism

Kavedilol metabolized primarily in the liver, primarily due to the formation of glucuronides. Demethylation and hydroxylation of the phenyl ring results in the formation 3 metabolites with beta activity adrenoblokiruyuschey; 4-hydroxy metabolite of beta-blocker in 13 times more active carvedilol. At the same time, active metabolites possess weaker vasodilator properties, and 2 gidroksikarbazolovyh metabolite is more potent antioxidants as compared to the parent compound.

Deduction

Average T1/2 karvedilola - 6-10 no. The clearance of plasma - 590 ml / min. Carvedilol is derived mainly from the bile.

Pharmacokinetics in special clinical situations

The concentration of carvedilol plasma levels in elderly patients 50% better, than young.

Carvedilol is derived mainly through the digestive tract, therefore, renal impairment is not observed drug accumulation.

In cirrhosis apparent Vd significantly increased, bioavailability carvedilol 4 times, than normal, Cmax – in 5 times more, than normal.

Carvedilol substantially not removed from the blood during dialysis.

Talliton: testimony

  • essential hypertension (alone or in combination with a diuretic);
  • stable angina;
  • congestive heart failure (II and III functional class NYHA classification) in combination with a diuretic, digoxin or ACE inhibitors.

Talliton: dosing regimen

At essential hypertension the initial dose is 12.5 mg 1 times / day for 2 days (1 tab. by 12.5 mg in the morning or 1 tab. 6.25 mg 2 times / day, morning and evening). The recommended maintenance dose – 25 mg (1 tab. by 25 mg in the morning or 1 tab. 12.5 mg 2 times / day, morning and evening).

With little effect, but not earlier 14 days of treatment, dose can be increased up to the maximum - 50 mg / day (by 25 mg 2 times / day, morning and evening).

The maximum single dose - 25 mg, The maximum daily dose - 50 mg.

At chronic stable angina The recommended starting dose – by 12.5 mg 2 times / day (in the morning and in the evening) during 2 first days. The recommended maintenance dose - 25 mg 2 times / day (in the morning and in the evening).

The recommended starting dose is 3.125 mg 2 times / day for 14 days (1/2 tab. by 6.25 mg in the morning and evening). If the treatment is well tolerated and has a clinical need, the dose can be increased to 6.25 mg 2 times / day (by 1 tab. 6.25 mg in the morning and evening). Perhaps subsequent increase in dose to 12.5 mg 2 times / day (by 1 tab. 12.5 mg in the morning and evening), then to 25 mg 2 times / day (by 1 tab. 25 mg in the morning and evening). Patients received the maximum tolerated dose. The maximum dose for patients weighing up to 85 kg - By 25 mg 2 times / day (in the morning and in the evening) and 50 mg 2 times / day (in the morning and in the evening) – to patients weighing more 85 kg.

At the beginning of treatment, and to increase the dose of each state of the patients should be monitored, tk. possibly worsening heart failure. It may develop fluid retention, but due to the vasodilator effect - hypotension and lethargy. When fluid retention should increase the dose of diuretics, Besides, may require dose reduction Talliton. In some cases, the treatment should be interrupted Talliton.
