Кромоспир: Definition and Active Ingredient

Кромоспир is a pharmaceutical preparation whose single active ingredient is Sodium Cromoglycate, also commonly referred to as Cromolyn sodium. This substance is a synthetic compound derived from the chromone chemical structure, establishing it as a single-active ingredient product. It is primarily formulated into various aqueous solutions, utilizing pharmaceutical excipients tailored for compatibility with sensitive mucous membranes. The compound is recognized for its role as a key preventative agent in managing chronic allergic issues, a property recognized within medical directories.

Pharmacological Class and Primary Function

Кромоспир belongs to the pharmacological class of mast cell stabilizers. Its primary function is to provide prophylactic (preventative) treatment, serving as an effective antiallergic agent for susceptible individuals, such as patients with seasonal allergies. This action is achieved by stabilizing mast cells, thereby inhibiting the release of potent inflammatory mediators, such as histamine and leukotrienes, which are responsible for triggering allergic symptoms. This key stabilizing property helps patients maintain a normal state by preventing allergic episodes from developing rather than treating acute, severe symptoms once fully established.

Available Forms and Primary Delivery Routes

The active compound is formulated into specialized dosage forms to facilitate direct, localized action at the mucous membranes where allergic reactions begin. These preparations typically include ophthalmic solutions (eye drops), nasal sprays, and inhalation solutions for nebulization. This structural variation reflects the drug's intended delivery via ocular, nasal, and pulmonary routes, maximizing the compound’s localized stabilizing effect against sensitizing allergens and allowing for focused administration in both adults and children.

What side effects are possible with Кромоспир?

Official Safety Profile of Кромоспир (Sodium Cromoglycate)

Official regulatory documents classify the possible adverse effects of Sodium Cromoglycate based on frequency and the body system affected. Since the medicine is delivered locally (ocular, nasal, or respiratory routes), adverse reactions are often confined to the site of application.

Common Adverse Reactions

The most commonly reported adverse reactions are related to local irritation. These include transient stinging or burning when using the ophthalmic solution, or throat irritation and cough following inhalation. Gastrointestinal effects such as nausea and diarrhea, as well as headache, are also commonly documented, particularly with higher systemic exposure from oral or inhalation forms.

System-Organ Class Example Documented Adverse Reactions
Respiratory Disorders Cough, throat irritation, nasal irritation
Gastrointestinal Disorders Nausea, diarrhea, unpleasant taste
Nervous System Disorders Headache, dizziness
Eye Disorders Transient stinging, burning, blurred vision

Serious Adverse Reactions and Safety Constraints

Regulatory labeling specifies that rare, but serious, adverse reactions include severe hypersensitivity reactions, such as anaphylaxis (a severe allergic reaction) and angioedema (swelling of the face, tongue, or throat). Paradoxical increased wheezing or difficulty in breathing is also documented as a serious risk, emphasizing that the medicine is only for prophylactic use and has no role in treating acute symptoms.

Use of the medicine is contraindicated in individuals with known hypersensitivity to the active ingredient or any excipients. Caution is noted for patients with pre-existing renal or hepatic impairment, as elimination of the compound may be decreased, which could potentially increase the effects of the medicine.

Therapeutic Uses of Кромоспир

What Кромоспир Treats: Main Uses and Benefits

The primary therapeutic use of Кромоспир (Sodium Cromoglycate) is to provide prophylactic support—meaning its role is to provide supportive symptom management in anticipation of symptoms. The preparation is used across conditions presenting with episodic or fluctuating manifestations related to allergy.

The medication is commonly used in situations to help address the irritating manifestations of several key conditions, including allergic rhinitis, allergic conjunctivitis, mild-to-moderate bronchial asthma, and specialized cases like systemic mastocytosis and exercise-induced bronchoconstriction (EIB). It is relevant when supportive symptom management is appropriate, and helps manage symptom clusters that may become intense or disruptive.

In clinical scenarios, it is applied in addressing symptoms of physiological responses, such as chronic sneezing, intense itching, and recurrent wheezing. Кромоспир provides support that helps ease the overall symptom burden, assisting with maintaining functional stability and contributing to improved day-to-day comfort during symptomatic periods.


Quick Fact: Relief for Recurrent Allergic Symptoms The primary purpose is supportive relief, helping patients cope more steadily with symptom fluctuations associated with seasonal or perennial allergen exposure.

Eligibility and Restrictions for Use

Who Can and Cannot Use Кромоспир?

Eligibility for using Кромоспир (Sodium Cromoglycate) is strictly defined by official regulatory labeling, focusing on specific patient populations and health conditions.


Contraindicated Populations

The medicine is contraindicated and must not be used by patients with a known hypersensitivity or allergy to cromolyn sodium or to any of the non-active ingredients (excipients) found in the specific product formulation. This is the primary absolute exclusion.

Age-Related Eligibility and Restrictions

Population Eligibility Status (Regulatory Wording)
Adults Generally permitted for all labeled indications.
Pediatric (Under 2 years) Safety and effectiveness have not been established for the inhalation solution; use of the oral solution is not recommended unless benefits outweigh the risks.
Geriatric (Over 65) Requires cautious dose selection due to a greater frequency of decreased renal or hepatic function in this population.

Conditional Use and Impairment

Use requires caution and consideration of a dosage adjustment in patients with impaired renal function (kidney disease) or impaired hepatic function (liver disease). The recommended dosage should be decreased in these populations. For women who are pregnant, use is advised only if clearly needed (FDA Pregnancy Category B). Caution should be exercised when administering the medicine to a nursing woman, as it is not known whether the drug is excreted in human milk.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Regulatory documentation indicates that Кромоспир (Sodium Cromoglycate) has a minimal profile for systemic drug–drug interactions, primarily due to its poor absorption and the fact that the absorbed fraction is eliminated largely unchanged. The medicine does not engage in significant interaction pathways involving liver metabolic enzymes, such as Cytochrome P450 (CYP).

The official interaction profile focuses on administration constraints and population-dependent exposure considerations.

Key Interaction Restrictions

Constraint Type Interacting Substance/Condition Restriction Description
Drug-Food Incompatibility Food, fruit juice, milk (Oral Form) The oral formulation must not be mixed with these substances, as doing so may impair the medicine’s function.
Physical Incompatibility Certain Inhaled Solutions The inhalation solution must not be physically mixed in the nebulizer cup with certain other solutions (e.g., Ipratropium) to prevent precipitation or loss of efficacy.

Population-Specific Exposure Note

Patients with impaired renal function (kidney) or impaired hepatic function (liver) may experience increased systemic exposure of Sodium Cromoglycate. This is because the drug's absorbed portion relies on both the renal and biliary routes for elimination, and a reduction in the function of either organ can decrease clearance.

Mechanism of Action

How Кромоспир Works

Mast Cell Stabilization and Calcium Ion Regulation

The drug’s mechanism is centered on the mast cell, a primary cellular target in the Type I hypersensitivity pathway. Кромоспир functions as a membrane stabilizer, primarily by modulating the necessary calcium ion ( Ca^2+) influx required for the cell to activate. This action targets a core molecular step in the cellular cascade, preventing the cell from reaching the necessary threshold for degranulation upon external stimulus.

Inhibition of Inflammatory Mediator Exocytosis

By successfully blocking the molecular signal ( Ca^2+ entry), the drug inhibits the physical process of exocytosis—the fusion and emptying of the mast cell's granules. This prevents the release of powerful inflammatory compounds, such as histamine and leukotrienes, into the surrounding mucosal tissue. This functional interruption of the cascade modulates the local physiological events that follow mediator release, including changes in local vascular permeability and smooth muscle excitation.

⏰ Mechanistic Constraint and Activity Profile

The mechanism acts as an upstream regulator that requires the compound to occupy the cellular target prior to the stimulus event. This molecular constraint limits the mechanism to prevention of the initiating cellular event, defining its physiological scope as non-reversing for established pathway activity. The activity profile is thus defined by its requirement to establish a stable cellular state.

Dosage and Administration Information

How to Use Кромоспир

The usage of Кромоспир (Sodium Cromoglycate) is characterized by established parameters based on the required administration route, focusing on continuous, preventative application.

Administration Routes and Dosing Patterns

The administration routes include Topical Ophthalmic, Intranasal, Oral Inhalation via nebulizer, and Oral solution for systemic use. Maintenance dosing across these forms is typically administered four times daily (QID) at regularly sustained intervals to maintain the necessary prophylactic effect.

Administration Form Standard Adult Regimen Special Timing
Oral Solution Initial dose: 200 mg (two ampoules). Taken 30 minutes before scheduled meals and at bedtime.
Inhalation Solution 20 mg (one single-use vial). Single 20 mg dose is administered 10 to 15 minutes prior to physical activity for acute prophylaxis.
Ophthalmic Solution 1 to 2 drops instilled in each eye. Administered QID at regular intervals.

Preparation and Procedural Constraints

For the oral form, the contents of the ampoule(s) are completely diluted in a glass of water and stirred before ingestion. For the inhalation solution, the 20 mg vial is administered undiluted using only a power-driven nebulizer; manual devices are unsuitable for proper delivery. The oral solution is only for ingestion and is explicitly not for inhalation or injection. Since the preventative action is not immediate, consistent use for up to 4 weeks may be necessary to achieve the maximum benefit. Once symptoms are controlled, particularly in systemic conditions, the dose may be gradually reduced to the minimum effective maintenance level.
