Pharmacological properties
Pharmacodynamics.
Mechanism of action.
Carvedilol is a non-selective β-blocker with vasodilator activity. It also has antioxidant and antiproliferative properties.
Pharmacodynamic effects.
The active ingredient carvedilol is a racemate; the enantiomers differ in their effects and metabolism. The S(–)-enantiomer has activity directed at blocking both α1- and β-adrenoceptors, while the R(+)-enantiomer exhibits activity directed at blocking only α1-adrenoceptors. Due to cardioselective blockade of β-adrenoceptors, it reduces blood pressure, heart rate and cardiac output. Carvedilol reduces pulmonary artery pressure and right atrial pressure. By blocking α1-adrenoceptors, it causes peripheral vasodilation and reduces systemic vascular resistance. Due to these effects, the load on the heart muscle is reduced and the development of angina is prevented. In patients with heart failure, this leads to an increase in the ejection fraction from the left ventricle and a decrease in the symptoms of the disease. Similar effects were observed in patients with left ventricular dysfunction.
Carvedilol does not exhibit intrinsic sympathomimetic activity and, like propranolol, has membrane-stabilizing properties. Plasma renin activity is reduced and fluid retention is rare. Certain properties of traditional β-blockers appear to be absent from some vasodilator β-blockers such as carvedilol.
Clinical efficacy and safety.
Clinical studies have shown that the balance of vasodilation and β-blockade provided by carvedilol causes the following effects.
Hypertension: The effect on blood pressure and heart rate is most pronounced 1–2 hours after administration.
In patients with arterial hypertension and healthy kidneys, carvedilol reduces renal vascular resistance. There are no significant changes in glomerular filtration, renal blood flow, and electrolyte excretion.
Carvedilol has been shown to maintain stroke volume and reduce total peripheral resistance without compromising the blood supply to individual organs and vascular beds, such as the kidneys, skeletal muscles, forearms, legs, skin, brain, or carotid artery. The incidence of cold extremities and early fatigue during physical activity is reduced.
Hypertensive patients with renal failure. Several open-label studies have shown that carvedilol is effective in patients with renal hypertension, chronic renal failure, hemodialysis patients, or renal transplant patients. Carvedilol produces a gradual reduction in blood pressure on dialysis and nondialysis days, and the blood pressure-lowering effects are comparable to those seen in patients with normal renal function.
Stable angina. In patients with stable angina, carvedilol has demonstrated anti-ischemic (improved total exercise time, time to 1 mm ST-segment depression, and time to angina) and antianginal properties that were maintained during long-term treatment. Acute hemodynamic studies have demonstrated that carvedilol significantly reduces myocardial oxygen demand and sympathetic overactivity, and reduces myocardial preload (pulmonary artery pressure and pulmonary wedge pressure) and afterload (total peripheral resistance), with subsequent improvement in left ventricular systolic and diastolic function without significant changes in cardiac output.
Carvedilol has no adverse effect on metabolic risk factors for coronary heart disease. It does not affect normal serum lipid levels, and in hypertensive patients with dyslipidemia, a beneficial effect on serum lipids has been observed after 6 months of oral therapy.
Two studies compared carvedilol 25 mg twice daily with other antianginal drugs with proven efficacy in patients with chronic stable angina pectoris. The selected dosing regimens were widely used in clinical practice. Both trials were double-blind, parallel-group designs. The primary objective was to determine total exercise time (TET).

The results of both studies clearly demonstrated that there was no significant difference in VTE at trough levels after 12 weeks of therapy. However, the hazard ratios derived from the Cox proportional hazards model showed a trend in favor of carvedilol, indicating that on average carvedilol was 114% more effective than verapamil (90% CI [confidence interval]: 85–152%) and 134% more effective than isosorbide dinitrate (90% CI: 96–185%). This also applied to time to angina and ST-segment depression. The increase in VTE was about 50 seconds in all groups; the improvements in time to angina and ST-segment depression were about 30 seconds, which is clinically significant.
In study 060, 48-hour Holter monitoring demonstrated a reduction in the number and duration of ST-segment depressions (silent myocardial ischemia) in both treatment groups. Carvedilol also reduced premature atrial and ventricular contractions, couplings, and conduction.
Chronic heart failure. Carvedilol significantly reduces mortality and the need for hospitalization and improves symptoms and left ventricular function in patients with ischemic or non-ischemic chronic heart failure. The effect of carvedilol is dose-dependent.
Patients with chronic heart failure and renal failure. Carvedilol reduces morbidity and mortality in dialysis patients with dilated cardiomyopathy, as well as all-cause mortality, cardiovascular mortality, and mortality from heart failure or the need for first hospitalization in heart failure patients with mild to moderate chronic kidney disease not requiring dialysis. A meta-analysis of placebo-controlled clinical trials involving a large number of patients (> 4000) with mild to moderate chronic kidney disease supports the treatment of patients with left ventricular dysfunction, with or without symptomatic heart failure, with carvedilol to reduce the risk of death and heart failure-related events.
Pediatric Patients. The safety and efficacy of carvedilol in children and adolescents have not been established due to the limited number and size of studies. The available studies have focused on the treatment of pediatric heart failure, which differs from adult disease in characteristics and etiology. Due to the small number of participants compared to studies in adults and the lack of an optimal dosing regimen for children and adolescents, the available data are insufficient to establish the pediatric safety profile of carvedilol.
Pharmacokinetics.
Absorption.
Carvedilol is rapidly and almost completely absorbed after oral administration. It is almost completely bound to plasma proteins. The volume of distribution is approximately 2 l/kg. The plasma concentration is proportional to the applied dose.
Due to extensive first-pass metabolism in the liver (mainly by the hepatic enzymes CYP2D6 and CYP2C9), the bioavailability of carvedilol is only about 30%. Three active metabolites are formed that exhibit β-blocking activity; one of them (the 4'-hydroxyphenyl derivative) has 13 times the β-blocking activity of carvedilol. Compared with carvedilol, the active metabolites have weak vasodilator activity. Metabolism is stereoselective; therefore, the plasma level of R(+)-carvedilol is 2–3 times higher than that of S(–)-carvedilol. The plasma levels of the active metabolites are about 10 times lower than those of carvedilol. The half-life varies greatly: 5–9 hours for R(+)-carvedilol and 7–11 hours for S(–)-carvedilol.
In elderly patients, an increase in carvedilol levels of approximately 50% is observed.
In patients with cirrhosis of the liver, the bioavailability of carvedilol is increased by 4 times, and the maximum plasma concentration is 5 times higher than in healthy subjects. In patients with impaired liver function, the bioavailability increases to 80% due to reduced first-pass metabolism. Since carvedilol is excreted mainly in the feces, significant accumulation of the drug is unlikely in patients with impaired renal function.
The presence of food in the stomach slows down the rate of absorption of the drug, but this does not affect its bioavailability.
Distribution.
Carvedilol is highly lipophilic, with plasma protein binding of about 95%. The volume of distribution ranges from 1.5 to 2 l/kg and is increased in patients with cirrhosis.
Biotransformation.
In humans, carvedilol is extensively metabolized in the liver by oxidation and conjugation to various metabolites, which are excreted mainly in the bile. Enterohepatic circulation of the parent compound has been demonstrated in animals.
Demethylation and hydroxylation on the phenolic ring form three metabolites with beta-adrenergic blocking activity.
Pharmacokinetic studies in humans have shown that the oxidative metabolism of carvedilol is stereoselective. Based on in vitro studies, it is suggested that various cytochrome P450 isoenzymes may be involved in the oxidation and hydroxylation processes, including CYP2D6, CYP3A4, CYP2E1, CYP2C9, and CYP1A2.
Studies in healthy volunteers and patients have shown that the R-enantiomer is predominantly metabolized by CYP2D6. The S-enantiomer is predominantly metabolized by CYP2D6 and CYP2C9.
Genetic polymorphism.
Results from clinical pharmacokinetic studies in humans have shown that CYP2D6 plays an important role in the metabolism of R- and S-carvedilol. As a result, plasma concentrations of R- and S-carvedilol are increased in CYP2D6 poor metabolizers. The importance of CYP2D6 genotype in the pharmacokinetics of R- and S-carvedilol has been confirmed in population pharmacokinetic studies, while other studies have not confirmed this observation. It was concluded that CYP2D6 genetic polymorphisms may be of limited clinical significance.
Elimination.
After a single oral dose of 50 mg carvedilol, about 60% is excreted in the bile and in the feces as metabolites within 11 days. After a single oral dose, only about 16% is excreted in the urine as carvedilol or its metabolites. Urinary excretion of unchanged drug is less than 2%. After intravenous infusion of 12.5 mg in healthy volunteers, plasma clearance of carvedilol reaches about 600 ml/min, and the half-life is about 2.5 hours. The half-life of the 50 mg capsule observed in the same subjects was 6.5 hours, which actually corresponds to the half-life of the capsule. After oral administration, the total body clearance of S-carvedilol is about twice that of R-carvedilol.
Special patient groups.
Elderly: Age has no statistically significant effect on the pharmacokinetics of carvedilol in patients with hypertension.
Pediatric patients: Studies in pediatric patients have shown that weight-adjusted clearance is significantly higher in children compared to adults.
Hepatic impairment: In a study in patients with cirrhosis, carvedilol bioavailability was four times higher, peak plasma concentration was five times higher, and volume of distribution was three times higher than in healthy volunteers.
Renal impairment: Since carvedilol is primarily excreted in the feces, significant accumulation in patients with renal impairment is unlikely.
In patients with arterial hypertension and renal insufficiency, the area under the concentration-time curve, half-life, and maximum plasma concentration are not significantly altered. Renal excretion of unchanged drug is reduced in patients with renal insufficiency; however, changes in pharmacokinetic parameters are modest.
Carvedilol is not removed by dialysis because it does not cross the dialysis membrane, probably due to its high level of plasma protein binding.
Heart failure: In a study of 24 Japanese patients with heart failure, the clearance of R- and S-carvedilol was significantly lower than previously estimated in healthy volunteers. These results suggest that the pharmacokinetics of R- and S-carvedilol are significantly altered in heart failure in Japanese patients.
Preclinical safety data.
No special hazard for humans was identified based on conventional studies of safety pharmacology, repeated dose toxicity, genotoxicity and carcinogenic potential.
Impairment of Fertility: When high doses of carvedilol were administered to pregnant rats (≥ 200 mg/kg - at least 100 times the maximum daily human dose), adverse effects on pregnancy and fertility (poor mating, fewer corpora lutea, and fewer implants) were observed.
Teratogenicity: Animal studies do not indicate a teratogenic effect of carvedilol.
Embryotoxicity (increased post-implantation mortality) was observed, but no malformations were observed in rats and rabbits at doses of 200 mg/kg and 75 mg/kg, respectively (38-100 times the maximum daily human dose). The relevance of these findings to humans is unknown. In addition, animal studies have shown that carvedilol crosses the placental barrier, so the possible effects of alpha and beta blockade on the fetus and newborn should also be borne in mind (see section "Use during pregnancy and lactation").
Therefore, effects in non-clinical studies were observed only at exposures considerably in excess of the maximum human exposure, indicating little relevance to clinical use (see section 4.6).

Interaction with other medicinal products and other types of interactions
Some antiarrhythmics, narcotics, antihypertensives, drugs for the treatment of angina, other β-blockers (e.g. in the form of eye drops), drugs that reduce the level of catecholamines (e.g. monoamine oxidase inhibitors, reserpine), and cardiac glycosides may enhance the effects of carvedilol. Therefore, the dose of these drugs and Coriolus® should be selected with caution.
Pharmacokinetic interactions.
Digoxin: Increased digoxin exposure (by almost 20%) has been observed in some studies in healthy volunteers and patients with heart failure. A significantly greater effect was observed in male patients compared to female patients. Therefore, it is recommended to monitor digoxin levels when initiating, adjusting or discontinuing carvedilol. Carvedilol did not affect intravenously administered digoxin.
Inducers or inhibitors of P-glycoprotein, CYP2D6, CYP2D9.
Carvedilol is an inhibitor of P-glycoprotein, therefore the bioavailability of drugs transported by P-glycoprotein may be increased when used concomitantly with carvedilol. In addition, the bioavailability of carvedilol may be altered by inducers or inhibitors of P-glycoprotein.
Fluoxetine and Paroxetine.
In a randomized crossover study in 10 patients with heart failure, concomitant administration of fluoxetine, a potent CYP2D6 inhibitor, resulted in stereoselective inhibition of carvedilol metabolism with a 77% increase in mean AUC of the R(+) enantiomer and a non-statistical 35% increase in AUC of the S(–) enantiomer compared to placebo. However, there were no differences in adverse events, blood pressure, or heart rate between treatment groups. The effect of a single dose of paroxetine, a potent CYP2D6 inhibitor, on the pharmacokinetics of carvedilol was studied in 12 healthy subjects after a single oral dose. Despite a significant increase in exposure to R- and S-carvedilol, no clinical effects were observed in these healthy subjects.
β-agonist bronchodilators.
Non-cardioselective β-blockers antagonize the β-agonist effects of bronchodilators, so such patients require close monitoring.
Hepatic Metabolism Inducers and Inhibitors: Rifampicin decreases carvedilol plasma concentrations by approximately 70%. Cimetidine increases AUC by approximately 30% but does not cause any change in Cmax. Caution may be warranted in those taking mixed-function oxidase inducers, such as rifampicin, as serum carvedilol levels may be decreased, or mixed-function oxidase inhibitors, such as cimetidine, as serum levels may be increased. However, based on the relatively small effect of cimetidine on carvedilol drug levels, the likelihood of any clinically significant interaction is minimal.
Catecholamine-depleting drugs: Patients taking both drugs with β-blocking properties and a drug that may deplete catecholamines (e.g., reserpine and monoamine oxidase inhibitors) should be closely monitored for signs of hypotension and/or severe bradycardia.
In addition, there is evidence that CYP3A4 is involved in the metabolism of carvedilol. Since tacrolimus is a substrate of P-glycoprotein and CYP3A4, carvedilol may also affect its pharmacokinetics through these interaction mechanisms.
Effect of other drugs on the pharmacokinetics of carvedilol.
Inhibitors and inducers of CYP2D6 and CYP2C9 may stereoselectively alter the systemic and/or presystemic metabolism of carvedilol, resulting in increased or decreased plasma concentrations of R- and S-carvedilol. Some examples of such drug effects observed in patients or healthy subjects are given below.
Antiarrhythmic drugs.
Isolated cases of conduction disturbances (rarely with haemodynamic compromise) have been observed when carvedilol and diltiazem have been administered concomitantly. For other drugs with β-blocking properties, ECG and blood pressure monitoring are recommended when carvedilol is administered orally with calcium channel blockers such as verapamil or diltiazem. These drugs should not be administered intravenously.
Careful monitoring of the patient's condition is necessary when carvedilol is used concomitantly with amiodarone (oral) or class I antiarrhythmic drugs. Bradycardia, cardiac arrest, ventricular fibrillation have been reported shortly after the start of treatment with β-blockers in patients receiving concomitant amiodarone. There is a risk of heart failure in the case of concomitant intravenous therapy with class Ia or Ia antiarrhythmic drugs.
An in vitro study with human liver microsomes showed that amiodarone and desethylamiodarone inhibited the oxidation of R- and S-carvedilol. Trough concentrations of R- and S-carvedilol were significantly increased by 2.2-fold in heart failure patients receiving concomitant carvedilol and amiodarone compared with patients receiving carvedilol monotherapy. The effect on S-carvedilol was attributed to desethylamiodarone, a metabolite of amiodarone, which is a potent inhibitor of CYP2C9. Monitoring of β-blocking activity is recommended in patients receiving the combination of carvedilol and amiodarone.
Other antihypertensive drugs.
Like other drugs with β-blocking activity, carvedilol may enhance the effect of other concomitantly administered drugs that are antihypertensive in action (e.g. β1-receptor antagonists) or may cause hypotension in relation to their side effect profile.
Alcohol: Alcohol consumption has an acute hypotensive effect that may potentiate the blood pressure lowering effect of carvedilol. Since carvedilol is soluble in ethanol, the presence of alcohol may affect the rate and/or extent of intestinal absorption of carvedilol. In addition, carvedilol is partially metabolized by CYP2E1, an enzyme known to be induced and inhibited by alcohol.
Grapefruit juice: A single dose of 300 ml of grapefruit juice resulted in a 1.2-fold increase in carvedilol AUC compared to water. Although the clinical significance is unclear, patients should avoid concomitant grapefruit juice, at least until a stable dose-response relationship has been established.
Pharmacodynamic interactions.
Insulin or oral hypoglycemic agents: Drugs with β-blocking properties may enhance the blood sugar-lowering effect of insulin and oral hypoglycemic agents. The symptoms of hypoglycemia may be masked or attenuated (especially tachycardia). Therefore, regular monitoring of blood glucose levels is recommended for patients taking insulin or oral hypoglycemic agents.
Clonidine: Concomitant administration of clonidine with drugs with β-blocking properties may potentiate the blood pressure and heart rate lowering effects. When concomitant treatment with drugs with β-blocking properties and clonidine is terminated, the β-blocking drug should be discontinued first. Then, after a few days, clonidine therapy can be discontinued by gradually reducing the dosage.
Dihydropyridines.
When dihydropyridines and carvedilol are used concomitantly, careful patient monitoring should be ensured, as cases of heart failure and severe arterial hypotension have been reported.
Nitrates.
Enhances the hypotensive effect.
Nonsteroidal anti-inflammatory drugs (NSAIDs), estrogens, and corticosteroids.
Concomitant use of NSAIDs, estrogens or corticosteroids and beta-adrenergic blockers may lead to increased blood pressure and worsening blood pressure control, which results in water and sodium retention.
Sympathomimetics, α-mimetics and β-mimetics.
With simultaneous use, there is a risk of developing arterial hypertension and pronounced bradycardia.
Ergotamine.
With simultaneous use, vasoconstriction increases.
Muscle relaxants.
When carvedilol is combined with muscle relaxants, neuromuscular blockade is enhanced.
Xanthine derivatives.
It should be used with caution with xanthine derivatives (aminophylline, theophylline) due to reduced β-adrenergic blocking effect.
Anesthetics: Extreme caution should be exercised during anesthesia due to the synergistic negative inotropic and hypertensive effects of carvedilol and anesthetics.
Application features
Arterial hypotension.
Orthostatic hypotension.
Especially at the beginning of treatment with Coriolus® and when the dose is increased, orthostatic hypotension with dizziness and vertigo, sometimes also with fainting, may occur. Patients with heart failure, elderly patients, and patients taking other antihypertensive agents or diuretics are at greatest risk. These effects can be prevented by using a low initial dose of Coriolus®, carefully increasing the maintenance dose and taking the drug after a meal. Patients should be told about measures to avoid orthostatic hypotension (caution when standing up; if dizziness occurs, the patient should sit or lie down).
Discontinuation of treatment.
Carvedilol treatment should not be stopped abruptly, especially in patients suffering from ischemic heart disease.
Abrupt discontinuation of Coriolum® (as with other β-blockers) may cause sweating, tachycardia, dyspnea, and worsening of angina pectoris. Severe exacerbation of angina pectoris and myocardial infarction and ventricular arrhythmias have been reported in patients with angina pectoris after abrupt discontinuation of β-blocker therapy. Carvedilol treatment should not be discontinued abruptly, especially in patients with ischemic heart disease. The dose should be reduced gradually (over a period of 2 weeks).
Chronic heart failure.
In most cases, carvedilol should be prescribed in addition to diuretics, angiotensin-converting enzyme (ACE) inhibitors, digitalis and/or vasodilators in patients with chronic heart failure. Treatment should be initiated in a hospital setting under medical supervision. Therapy should only be initiated if the patient has been stable on standard basic therapy for at least 4 weeks. Patients with severe heart failure, salt depletion or dehydration, the elderly or with low baseline blood pressure should be monitored closely for approximately 2 hours after the first dose or after dose increases, as hypotension may develop. Hypotension due to excessive vasodilation is initially treated by reducing the dose of diuretics, and if symptoms persist, the dose of any ACE inhibitor can be reduced. At the beginning of treatment or during dose increase, worsening of heart failure or fluid retention may occur. In this case, it is necessary to increase the dose of the diuretic. However, in some cases, it may be necessary to reduce the dose or cancel the drug. The dose of carvedilol should not be increased until symptoms associated with worsening heart failure or arterial hypotension due to excessive vasodilation are controlled.
Carvedilol should be prescribed with caution to patients with chronic heart failure who are taking digitalis, as this combination prolongs atrioventricular conduction.
Carvedilol may cause bradycardia. If heart rate is < 55 beats/min and symptoms associated with bradycardia occur, the dose of the drug should be reduced.
Because carvedilol has an inherent negative dromotropic effect, it should be administered with caution to patients with first-degree heart block.
Kidney dysfunction.
In patients with heart failure and low blood pressure (systolic < 100 mm Hg), ischemic heart disease or systemic atherosclerosis and/or renal insufficiency, reversible deterioration of renal function has been observed during treatment with carvedilol. In patients with heart failure who have such risk factors, renal function should be monitored during titration of carvedilol. If significant deterioration of renal function is observed, the carvedilol dose should be reduced or treatment discontinued.
Diabetes.
Caution should be exercised when using carvedilol in patients with diabetes mellitus, as blood glucose control may deteriorate or early signs of acute hypoglycemia may be masked or attenuated. For patients with diabetes mellitus, regular monitoring of blood glucose levels is recommended when starting carvedilol or when the dose is increased by titration and appropriate adjustment of hypoglycemic therapy.
Diabetes mellitus and hyperthyroidism.
β-blockers slow the heart rate and therefore may mask hypoglycemia in patients with diabetes mellitus and thyrotoxicosis in patients with thyroid disease. In patients with heart failure and diabetes mellitus, blood glucose levels may decrease or increase.
Antiarrhythmic drugs.
When using carvedilol simultaneously with calcium channel blockers such as verapamil and diltiazem, or other antiarrhythmic drugs, especially amiodarone, blood pressure and ECG should be monitored, so their simultaneous intravenous administration should be avoided.
Thyrotoxicosis.
Carvedilol, like other drugs with β-blocking action, may mask the symptoms of thyrotoxicosis.
General anesthesia.
β-blockers reduce the risk of arrhythmias during anesthesia, but may also increase the risk of hypotension, so some anesthetics should be used with caution.
Carvedilol may in very rare cases cause deterioration of liver function. If clinical deterioration is suspected, liver function should be checked. In case of liver failure, the patient should stop taking Coriol®. As a rule, liver function normalizes after discontinuation of treatment.
Chronic obstructive pulmonary disease.
β-blockers may increase bronchial obstruction; therefore, these drugs are not recommended for use in patients with chronic lung disease. In exceptional cases, Coriolus® may be prescribed to patients with mild lung disease when other drugs are ineffective; however, careful monitoring is necessary. It is important that these patients take the lowest effective dose of Coriolus®. If signs of airway obstruction appear, treatment with Coriolus® should be discontinued immediately.
Peripheral vascular disease and Raynaud's syndrome.
Carvedilol should be used with caution in patients with peripheral vascular disease and Raynaud's syndrome, as β-blockers may exacerbate the symptoms of the disease.
Psoriasis.
Patients with a history of psoriasis associated with beta-blocker therapy should be prescribed carvedilol only after consideration of the benefit/risk ratio.
Carvedilol should be used with caution in patients with a history of serious hypersensitivity reactions and in those requiring desensitization, as β-blockers may increase sensitivity to allergens and the severity of anaphylactic reactions. The drug should also be used with caution in patients with psoriasis, as it may exacerbate skin reactions.
Prinzmetal's angina.
In patients with Prinzmetal's angina, nonselective β-blockers may cause chest pain (the α1-adrenoblocking effect of carvedilol may prevent this, but there is insufficient clinical experience with carvedilol in Prinzmetal's angina).
Concurrent use of debrisoquine.
Patients with poor metabolism of debrisoquine require caution at the beginning of treatment.
Pheochromocytoma.
Patients with pheochromocytoma should be given an alpha-blocker before any beta-blocker. Although carvedilol has both alpha- and beta-blocking pharmacological activity, there is no experience with carvedilol in this condition. Therefore, caution should be exercised when prescribing carvedilol to patients suspected of having pheochromocytoma.
Hypersensitivity reactions.
Carvedilol should be administered with caution to patients with a history of serious hypersensitivity reactions and those undergoing desensitization, as β-blockers may increase reactivity in allergy tests, increase sensitivity to allergens, and increase the severity of anaphylactic reactions.
Contact lenses: Contact lens wearers should be warned about the possibility of decreased tear production.
The safety and efficacy of Coriolus® in patients under 18 years of age have not been studied, therefore Coriolus® is not recommended for use in such patients.
