What Type of Medicine is Конкор (Bisoprolol)?

Конкор is a synthetic, single-ingredient pharmaceutical product manufactured by Merck Healthcare KGaA, classified as a cardioselective beta-blocker, based on the active ingredient Bisoprolol Fumarate. It is designated as a prescription-only medicine (Rx). Bisoprolol is recognized as a highly potent beta1-adrenergic receptor antagonist, a chemical structure that distinguishes it within the beta-blocker class by having a strong affinity for receptors predominantly located in the heart. This focused action is a key feature of its clinical profile.

Composition and Physical Form

The product is a single-ingredient medicine (monotherapy) that delivers Bisoprolol Fumarate in a solid, film-coated tablet form for oral administration. The Bisoprolol active substance is confirmed to be a synthetic compound. The brand formulation has been frequently utilized in clinical trials as a reference product, underscoring its established quality and standard formulation. Bisoprolol's comparatively long half-life is a differentiating factor that allows the medication to be administered once daily, which supports patient adherence. The tablet contains the synthetic active substance along with pharmaceutical excipients, ensuring reliable and controlled intake via the oral route.

General Purpose for Cardiovascular Support

The general purpose of Bisoprolol is to support the cardiovascular system by reducing the physical workload on the heart and helping to stabilize its function. By inhibiting the stimulating effects of adrenaline and related hormones, the medicine achieves a negative chronotropic effect, meaning it slows the heart rate and decreases the force of myocardial contraction. This principle is clinically recognized for improving the overall efficiency of the heart, which is a cornerstone of management for conditions where a reduced cardiac burden is necessary. By modulating sympathetic overactivity, Bisoprolol improves circulatory stability, making it essential for long-term cardiac support.

What side effects are possible with Конкор?

Possible Side Effects and Safety Information for Конкор (Bisoprolol)

Official regulatory documents classify the risks associated with this medication primarily through System-Organ Classes (SOCs), with major involvement in the Cardiovascular, Nervous System, and Gastrointestinal systems.

Key Adverse Reaction Categories

Adverse reactions are classified by frequency (e.g., Common, Uncommon, Rare). Common reactions are those affecting up to 1 in 10 patients and typically include fatigue, dizziness, headache, and gastrointestinal symptoms such as nausea, diarrhea, or constipation. A feeling of coldness or numbness in the extremities is also a recognized common event.

System-Organ Class Common Adverse Reactions
Nervous System Dizziness, headache
General Disorders Fatigue, asthenia (weakness)
Cardiovascular Bradycardia (slow heart rate)
Gastrointestinal Nausea, vomiting, diarrhea, constipation

Clinically Significant and Serious Reactions

Serious adverse reactions, which require immediate medical attention, include worsening of pre-existing heart failure, profound symptomatic bradycardia (excessively slow heart rate), and certain degrees of atrioventricular (AV) block. Uncommon reactions include hypotension (low blood pressure), depression, sleep disturbances (insomnia), and bronchospasm (especially in patients with a history of asthma or obstructive airway disease).

Safety Restrictions and Monitoring

Safety data emphasizes that therapy must not be stopped suddenly, particularly in patients with pre-existing ischemic heart disease, as this can lead to an acute deterioration of their condition, such as exacerbation of angina or myocardial infarction. Dose must be reduced gradually over approximately two weeks under medical guidance.

  • Population Specificity: Safety and efficacy are not established in children under 18 years of age. For patients with severe renal impairment (creatinine clearance <20 ml/min) or severe hepatic impairment, the dose should be carefully monitored and typically should not exceed 10 mg per day. Bisoprolol may mask symptoms of hypoglycemia in diabetic patients or signs of thyrotoxicosis in patients with hyperthyroidism, requiring cautious monitoring in these groups.

Overdose and Emergency Response

An overdose of Конкор (Bisoprolol Fumarate) is formally documented to result in manifestations of profound cardiodepression. The official prescribing information lists symptoms such as bradycardia (abnormally slow heart rate) and hypotension (low blood pressure), which may escalate to severe outcomes like cardiogenic shock, advanced AV block, or worsening heart failure. Other documented presentations include bronchospasm, nervous system effects like confusion, drowsiness, and convulsions. Hypoglycemia (low blood sugar) is a recognized finding, with regulatory sources noting it is common in the pediatric population following exposure.

Immediate Emergency Actions

Action Mandate Required Response
Seek Immediate Medical Attention Contact a poison control center immediately for expert instructions.
Severe Symptoms Present Call emergency services immediately (e.g., if the person has collapsed, has had a seizure, or has difficulty breathing).

Overdose Management Context

There is no specific antidote known for Bisoprolol overdose. Regulatory documents state that management involves providing supportive and symptomatic treatment to counter the physiological effects, such as the administration of intravenous fluids or glucagon. Continuous ECG monitoring and observation of vital signs are required due to the drug’s long duration of action.

Therapeutic Uses of Конкор

What Конкор Treats: Main Uses and Benefits

Конкор (Bisoprolol Fumarate) is applied across domains where additional symptomatic support is needed, addressing conditions characterized by periods of heightened symptoms and symptoms related to systemic imbalance. The medication is used to manage arterial hypertension, provide prophylaxis for stable angina pectoris (effort-induced chest pain), and serve as supportive therapy in stable chronic heart failure.

In clinical scenarios where symptoms interfere with routine activities, the medication is commonly used to help with conditions marked by increased physiological stress, where it is applied in addressing elevated blood pressure and symptoms related to heightened physiological activity. The therapy contributes to easing the overall symptom load, providing support during episodes of heightened discomfort and helps maintain a sense of stability when symptoms are more noticeable.

“The use of this medication in chronic conditions may assist with maintaining functional stability and supports general well-being during symptomatic phases.”

What should I know about interactions with other medicines?

Interactions with other medicines and products

The official regulatory profile for Bisoprolol Fumarate (Конкор) structures interactions based on the risk of adverse cardiodynamic or metabolic effects, resulting in strict regulatory classifications for co-administration.

Official Interaction Restrictions

Contraindicated Combinations are defined by regulatory documents, prohibiting co-administration with other beta-blocking agents due to the potential for excessive reduction of sympathetic activity. Combinations are generally not recommended (a high-risk classification) for Verapamil-type calcium antagonists, Class I antiarrhythmic drugs (e.g., Quinidine), and Clonidine-type centrally acting antihypertensive drugs due to severe risks like AV block, profound hypotension, or rebound hypertension upon withdrawal.

Documented Pharmacodynamic and Pharmacokinetic Effects

Pharmacodynamic interactions include co-administration with Dihydropyridine calcium antagonists (e.g., Amlodipine), which may increase the risk of hypotension, and with Digitalis glycosides (e.g., Digoxin), which may increase the risk of bradycardia. NSAIDs may decrease the antihypertensive efficacy of Bisoprolol. Regarding metabolic effects, the regulatory label notes that Rifampicin increases metabolic clearance, causing a shortened elimination half-life and reduced Bisoprolol plasma exposure. Furthermore, the antihyperglycemic effects of Insulin and oral anti-diabetic drugs may be intensified, and the symptoms of hypoglycemia may be masked. The absorption of Bisoprolol is officially documented as not affected by the presence of food.

Mechanism of Action

Selective Blockade of Cardiac beta1 Receptors

This core mechanism involves the drug acting as a highly selective antagonist of the beta1-adrenergic receptor (beta1-AR) in the heart, preventing the binding of stimulating hormones like norepinephrine. The molecular blockade suppresses the internal G s-protein-mediated cascade, leading directly to a slowing of the heart rate (negative chronotropy) and a decrease in the force of myocardial contraction (negative inotropy). The combined reduction in rate and force reduces the oxygen consumption of the myocardium.

Modulation of the Renin-Angiotensin System

Koncor’s mechanism extends to the kidneys, where the beta1-AR blockade suppresses the release of renin from the juxtaglomerular cells. By interrupting this initiating step of the RAAS pathway, the drug limits the production of the vasoconstrictor Angiotensin II. This action influences the systemic signaling cascade, contributing to a change in vascular resistance.

Mechanism Boundary: Loss of Selectivity

The advantage of beta1-selectivity is inherently concentration-dependent. At higher concentrations, the drug loses its preference and begins to competitively block beta2-adrenergic receptors, which are abundant in the airways and vasculature. This functional shift to beta2-adrenergic antagonism results in physiological effects such as increased airway resistance when the concentration exceeds the beta1-selective range.

Dosage and Administration Information

Конкор (Bisoprolol fumarate) should be taken exactly as prescribed by your physician. It is essential to follow all instructions on the prescription label and patient information leaflet.

Administration

  • The tablets are typically taken once daily in the morning, with or without food. They should be swallowed whole with a glass of water. Do not crush or chew the tablets unless specifically advised by your doctor, as this may affect how the medicine works.
  • For high blood pressure or angina, the usual starting dose is 5 mg once daily, with a maximum dose generally not exceeding 20 mg per day.
  • For stable chronic heart failure, treatment begins at a low dose, such as 1.25 mg once daily, and is gradually increased by the doctor over a period of weeks or months based on your response. The maximum recommended daily dose for heart failure is usually 10 mg.

Important Considerations

Action Instruction
If you miss a dose Take it as soon as you remember that day. If you do not remember until the next day, skip the missed dose and take the next dose at the usual time. Never take a double dose to make up for a forgotten one.
Stopping Treatment Do not stop taking Bisoprolol suddenly, even if you feel well. Abrupt discontinuation can worsen your heart condition or increase the risk of heart attack or stroke. Your doctor will advise a gradual dose reduction over at least a week if treatment needs to be stopped.
Monitoring Regular monitoring of your blood pressure and heart rate is necessary, especially during the initial phase and dose adjustments. Always keep scheduled appointments with your doctor.

Treatment with Bisoprolol is typically long-term. Continue to take your medication as directed to control your condition, even if you experience no symptoms.

Recent Clinical Evidence

Recent Clinical Evidence Overview

Clinical research on bisoprolol (the active ingredient in Конкор) has primarily focused on its role in chronic heart failure (CHF) and hypertension. Guidelines from major cardiology organizations affirm its role as a key component of management for heart failure with reduced ejection fraction (HFrEF).


Core Efficacy Findings

Large randomized trials, such as the Cardiac Insufficiency Bisoprolol Study II (CIBIS-II), investigated bisoprolol's impact when added to standard CHF therapy. Study findings included:

  • Chronic Heart Failure (CHF): Studies observed that bisoprolol was associated with a reduction in all-cause mortality and sudden cardiac death compared to placebo in patients with stable, moderate-to-severe CHF.
  • Hypertension: Trials demonstrate that bisoprolol use is associated with dose-dependent reductions in both systolic and diastolic blood pressure over a 24-hour period.

Combination Therapies and Safety Profile

Recent research continues to examine fixed-dose combinations (FDCs) of bisoprolol with other anti-hypertensive agents, such as amlodipine or hydrochlorothiazide. Studies suggest that FDCs may promote adherence and lead to clinically relevant reductions in blood pressure. The drug’s high selectivity for beta1 receptors is a point of study, with research exploring its minimal impact on metabolic parameters and lung function compared to less selective agents.

  • Tolerability: Common adverse events reported in clinical trials include fatigue, headache, dizziness, and bradycardia (slow heart rate). Serious adverse events are monitored, and incidence has been reported as comparable between treatment and placebo groups in major heart failure trials.

Frequently Asked Questions (FAQ)

Common questions about Конкор (FAQ)

Q: What is Конкор used for?

Конкор (Bisoprolol Fumarate) is a type of medicine known as a beta-blocker. It is primarily used to treat several heart and circulation conditions, including:

  • High blood pressure (hypertension): It helps to lower the pressure by making the heart beat slower and with less force.
  • Chronic stable angina pectoris: This is chest pain caused by reduced blood flow to the heart. Bisoprolol helps reduce the heart's workload.
  • Chronic stable heart failure: Used as an add-on treatment to standard therapy to improve symptoms and survival in patients with a stable, mild to severe condition.

Q: How does Конкор work to lower blood pressure?

Конкор works by selectively blocking beta-1 adrenergic receptors mainly located in the heart. This action has several effects that help lower blood pressure and reduce the heart's workload:

  1. Reduced Heart Rate: It slows down the heart rate, meaning the heart pumps less frequently.
  2. Reduced Force of Contraction: It decreases the force with which the heart muscle contracts.
  3. Decreased Renin Release: It can reduce the release of the hormone renin by the kidneys, which is part of a system that can raise blood pressure.

Together, these actions decrease the cardiac output and reduce the pressure exerted on the blood vessel walls, leading to lower blood pressure.


Q: Can I suddenly stop taking Конкор?

No, you should never stop taking Конкор suddenly unless specifically advised by a healthcare professional. Abruptly discontinuing beta-blockers, especially in people with heart conditions like angina or coronary artery disease, can lead to serious health problems. This is often called the beta-blocker withdrawal syndrome and can result in:

  • A significant increase in blood pressure (rebound hypertension).
  • Worsening chest pain (angina).
  • Heart attack or dangerous heart rhythm changes.

If your doctor decides you need to stop treatment, the dosage will typically be gradually reduced over 1-2 weeks to allow your body to adjust safely.


Q: What are the common side effects of Конкор?

While not everyone experiences them, some of the common side effects that may occur, particularly at the beginning of treatment, include:

  • Fatigue or tiredness
  • Dizziness or lightheadedness
  • Headache
  • Coldness or numbness in the extremities (hands and feet)
  • Gastrointestinal issues, such as nausea, vomiting, diarrhea, or constipation.

Most common side effects are mild and transient. If side effects persist or are bothersome, you should discuss them with your prescribing physician.


Q: Is Конкор the same as other blood pressure medicines?

No, Конкор (Bisoprolol) belongs to the class of drugs known as beta-blockers, which work in a specific way to lower heart rate and reduce the heart's pumping force. Other types of blood pressure medications work differently, for example:

  • ACE Inhibitors (e.g., ramipril, lisinopril): These widen blood vessels by blocking the formation of a substance called angiotensin II.
  • Calcium Channel Blockers (e.g., amlodipine): These relax the muscle cells in blood vessel walls.
  • Diuretics (Water Pills): These help the body eliminate excess sodium and water, reducing blood volume.

Because they have different mechanisms, doctors often combine Конкор with other classes of blood pressure medications to achieve the best therapeutic effect.
