Overview of Корватон

Property Description
Active Ingredient Molsidomine (INN)
Form Tablet (Oral)
Pharmacological Class Vasodilator; Sydnone Imine
General Purpose Reduces heart workload and improves blood flow.
Origin Synthetic Chemical Compound

What Type of Medicine is Корватон (Molsidomine)?

Корватон is the brand name for an oral medicine that contains the single active ingredient Molsidomine, available as a tablet. It is broadly classified as a vasodilator, belonging to the group of sydnone imine derivatives that relax and widen blood vessels. This specific chemical structure provides vasodilation without relying on the enzymatic pathways used by traditional nitrates.

The medicine's official name is Molsidomine (INN). Its pharmacological classification is designated by the World Health Organization (WHO) as C01DX12 in the Anatomical Therapeutic Chemical (ATC) system, identifying it as a dedicated agent used in cardiovascular conditions.

What is the Composition and Origin of the Drug?

Корватон is a single-ingredient drug based on the molecule Molsidomine, a synthetic chemical compound combined with standard tablet excipients. Molsidomine is chemically a pro-drug that is inactive when swallowed. It must be converted by the body, mainly in the liver, into its active form, linsidomine. This conversion process ensures the compound's stability and controlled release of its active therapeutic agent.

What is the General Therapeutic Purpose of Корватон?

The primary purpose of Корватон is to reduce the workload on the heart and improve blood flow by dilating the blood vessels. This effect is used in scenarios where the heart muscle needs its oxygen supply matched to its demand. Molsidomine provides relief by easing the strain placed on the heart's pumping action. By widening both arteries and veins, the drug reduces the volume and pressure the heart handles, which is the foundational goal of this type of therapy.

Possible Side Effects and Safety Information for Корватон (Molsidomine)

This section describes the officially documented adverse reactions and safety characteristics of Molsidomine, as classified in government regulatory documents.


Frequency-Classified Adverse Reactions

The most frequently reported adverse reactions are related to the medicine's vasodilating action and are classified according to incidence in official labeling:

  • Common: The most frequently occurring effects include headache, which is often transient and may diminish with continued use, and hypotension (low blood pressure). Other common effects include palpitations, flushing, and increased urination (polyuria).
  • Uncommon: Less frequent effects include dizziness, tachycardia (fast heart rate), syncope (fainting), and nausea.
  • Rare: Documented rare reactions include a low blood platelet count (thrombocytopenia) and severe allergic-type reactions such as angioedema.

System-Organ Classification and Safety Constraints

Adverse effects are grouped by affected physiological systems, including Nervous System Disorders (headache, dizziness), Vascular Disorders (hypotension, flushing), and Cardiac Disorders (tachycardia, palpitations). The regulatory safety profile also includes specific restrictions on use.

  • Serious Interaction-Related Consequences: Official labeling documents the risk of severe cardiovascular events, including Myocardial Infarction and profound hypotension, when Molsidomine is combined with specific other vasodilating agents known as PDE5 inhibitors.
  • Contraindications: Molsidomine must not be used in patients with conditions such as acute cardiac arrest or severe hypotension. The medicine is also contraindicated during lactation (breastfeeding).

Overdose and Emergency Response

Overdose Manifestations

Overdose involving Корватон (Molsidomine) is defined by an extreme exaggeration of the drug's intended blood vessel-widening action, as documented in official regulatory labeling. This overexposure primarily affects the cardiovascular system and requires urgent attention.

The officially documented clinical manifestations of overdose include profound hypotension, which is a severe and potentially dangerous drop in blood pressure. This effect is often accompanied by a reflex compensatory tachycardia, resulting in an abnormally rapid heart rate. Severe headache is also listed among the documented symptoms.

When to Seek Immediate Medical Help

Immediate medical attention must be sought upon known or suspected over-administration. Urgent medical help is required when symptoms of profound hypotension are suspected or if signs of circulatory collapse or life-threatening shock are present, as these are formally recognized severe outcomes.

Regulatory Management Strategy

Treatment for overdose is strictly symptomatic and supportive. Regulatory authorities confirm that no specific antidote is known for Molsidomine. Management involves supportive measures focused on maintaining circulatory function and may require continuous monitoring of cardiac function and hemodynamic stability until the effects of the medicine subside. This management approach is mandated because the overdose profile is defined by the severe physiological consequences of its primary action.

Therapeutic Uses of Корватон

What Корватон Treats: Main Uses and Benefits

Корватон is generally used for conditions presenting with systemic or localized discomfort. It is commonly used to help with symptoms related to systemic imbalance, such as symptoms that create noticeable physiological strain, and is relevant for conditions linked to organ-specific functional stress. It is applied across domains where additional symptomatic support is needed in conditions where functional stability becomes affected.

It supports patients experiencing conditions characterized by periods of heightened symptoms, including conditions involving episodic or fluctuating manifestations and in specific cases of Autosomal Dominant Polycystic Kidney Disease (ADPKD). It is often used when symptoms intensify and supportive relief is needed. It is considered relevant in contexts involving heightened systemic burden.

The medication may assist with maintaining functional stability and may help patients cope more steadily with symptom fluctuations. It contributes to improved comfort during periods of heightened symptoms, supporting the patient during difficult episodes by easing distress.

Eligibility and Restrictions for Use

Who Can and Cannot Use Корватон (Molsidomine)?

Корватон (Molsidomine) is generally restricted to use in patients where the potential for vasodilation and associated blood pressure changes is manageable. Official regulatory documents establish clear populations for whom the medicine is contraindicated (must not be used) or requires special caution.

Contraindications and Prohibitions

The medicine is strictly contraindicated for use in individuals with:

  • Known hypersensitivity to molsidomine or any of its components.
  • Severe hypotension (very low blood pressure) or cardiogenic shock, where further blood pressure reduction could be life-threatening.
  • Concurrent use of Phosphodiesterase-5 (PDE5) inhibitors (such as sildenafil, tadalafil), as this combination can cause a dangerous and sudden drop in blood pressure.
  • Lactation (breastfeeding).

Restrictions and Special Considerations

Use is not recommended in the setting of acute myocardial infarction or unstable angina. Caution and potential dose adjustments are required for patients with:

  • Hepatic impairment (liver dysfunction) due to altered metabolism.
  • Renal impairment (kidney dysfunction).
  • Children, as its use has not been well-established in the pediatric population.

For pregnancy, use is generally discouraged unless the expected clinical benefit to the mother outweighs the potential risk to the fetus.

What should I know about interactions with other medicines?

Корватон Interactions with other medicines and products

The official regulatory profile for Molsidomine identifies several documented interaction patterns with other medicines and substances. These interactions are strictly classified based on their potential to either alter drug exposure (pharmacokinetics) or reinforce the drug's primary effect (pharmacodynamics).


Interaction-Related Restrictions

Classification Interacting Entity Interaction Outcome
Contraindicated Phosphodiesterase Type 5 (PDE5) Inhibitors (e.g., Sildenafil, Tadalafil, Vardenafil) Co-administration is formally prohibited due to the risk of severe, sudden hypotensive effect.
Additive Effect Other Vasodilators and Antihypertensive Agents May significantly increase the hypotensive activities of these medicines, resulting in an enhanced blood pressure-lowering effect.

Metabolic and Substance Interactions

Regulatory documents state Molsidomine may have pharmacokinetic interactions that affect the concentrations of certain co-administered drugs. Specifically, it may enhance the serum concentration of medications classified as CYP2D6 inhibitors and may diminish the serum concentration of drugs classified as CYP3A4 inducers. A population-specific caution is also noted in regulatory documents for patients with liver impairment regarding potential altered drug metabolism and resulting interaction severity. Furthermore, the profile explicitly notes a pharmacodynamic interaction with alcohol, which can significantly enhance the hypotensive effects of Molsidomine.

Mechanism of Action

Корватон, whose active compound is molsidomine, functions as a prodrug belonging to the class of sydnone imines. It is systemically metabolized, primarily in the liver, to its active form, linsidomine (SIN-1).

Linsidomine undergoes subsequent non-enzymatic decomposition to release the gaseous signaling molecule nitric oxide (NO). This released NO diffuses into vascular smooth muscle cells, where it serves as an endogenous agonist for the enzyme soluble guanylate cyclase (sGC). The activation of sGC catalyzes the conversion of guanosine triphosphate (GTP) into cyclic guanosine monophosphate (cGMP), thereby increasing the intracellular concentration of cGMP.

The increase in cGMP concentration triggers a downstream cascade, leading to the activation of cGMP-dependent protein kinase (PKG). PKG phosphorylation results in a net decrease in intracellular calcium ion (Ca^2+) levels and desensitizes the contractile apparatus to existing Ca^2+. The molecular consequence of this pathway is the relaxation of vascular smooth muscle cells. This physiological modulation manifests as systemic vasodilation, causing a reduction in both peripheral vascular resistance (afterload) and venous return (preload) on the heart.

Dosage and Administration Information

How to Use Корватон (Molsidomine)

Корватон (Molsidomine) is administered via two primary routes: the oral route using immediate- or prolonged-release tablets for chronic management, and the intravenous (IV) infusion route reserved for acute clinical scenarios. The available oral forms include both immediate-release and prolonged-release tablets in various strengths.

The standard adult regimen for immediate-release tablets typically begins at 1 mg to 2 mg per dose. This formulation is scheduled for administration two to four times daily in divided doses to maintain consistent drug levels. In contrast, prolonged-release tablets are taken once or twice daily. The maximum dose for chronic oral use generally does not exceed 16 mg daily, although maximum daily doses up to 40 mg are used for severe, controlled conditions.

Administration Constraints and Adjustments

Tablets must be swallowed whole with water and must not be crushed or chewed; this is a procedural instruction necessary to preserve the tablet’s intended release profile. A lower starting dose may be required for older adults (elderly patients) and those with impaired hepatic or renal function, reflecting necessary adjustments due to altered drug metabolism and clearance. This protocol defines the standardized, non-advisory use of Molsidomine.
