Green (Solution, Spray) Instructions for Use

ATC Code

A01AD02 (Benzydamine)

Active Substance

Benzydamine (Rec.INN registered by WHO)

Clinical-Pharmacological Group

A drug with local anesthetic, antimicrobial, and anti-inflammatory action for topical application in dentistry

Pharmacotherapeutic Group

NSAID

Pharmacological Action

NSAID, an indazole derivative, without a carboxyl group. The absence of a carboxyl group imparts the following features: Benzydamine is a weak base (whereas most NSAIDs are weak acids), has high lipophilicity, and penetrates well into the site of inflammation (where pH is lower) along the pH gradient and accumulates in therapeutic concentrations.

It has an anti-inflammatory and local analgesic effect, and has an antiseptic (against a wide range of microorganisms), as well as an antifungal effect.

The anti-inflammatory effect is due to a decrease in capillary permeability, stabilization of cell membranes due to inhibition of synthesis and inactivation of prostaglandins, histamine, bradykinin, cytokines, complement factors and other nonspecific endogenous damaging factors.

Benzydamine suppresses the production of pro-inflammatory cytokines, especially TNFα, and to a lesser extent IL-1β. The main feature of benzydamine is that, being a weak inhibitor of prostaglandin synthesis, it demonstrates potent inhibition of pro-inflammatory cytokines. For this reason, Benzydamine can be classified as a cytokine-suppressing anti-inflammatory drug.

The local anesthetic effect of benzydamine is associated with the structural features of its molecule, similar to local anesthetics. The analgesic effect is due to an indirect decrease in the concentration of biogenic amines with algogenic properties and an increase in the pain sensitivity threshold of the receptor apparatus; Benzydamine also blocks the interaction of bradykinin with tissue receptors, restores microcirculation and reduces pain sensitivity at the site of inflammation.

Benzydamine has an antibacterial effect due to rapid penetration through the membranes of microorganisms with subsequent damage to cellular structures, disruption of metabolic processes and the function of cell lysosomes.

It has an antifungal effect against 20 strains of Candida albicans and Candida non-albicans, causing structural modifications of the fungal cell wall and their metabolic chains, thus preventing their reproduction.

Pharmacokinetics

When applied topically, it is well absorbed through the mucous membranes and quickly penetrates into inflamed tissues. It is detected in the blood plasma in an amount insufficient to obtain systemic effects. It is excreted mainly by the kidneys and through the intestines in the form of metabolites or conjugation products.

Indications

Symptomatic therapy of pain syndrome in inflammatory diseases of the oral cavity and ENT organs (of various etiologies): pharyngitis, laryngitis, tonsillitis; gingivitis, glossitis, periodontosis, stomatitis (including after radiation and chemotherapy); calculous inflammation of the salivary glands; after dental treatment or extraction; after surgical interventions and injuries (tonsillectomy, jaw fractures); candidiasis of the oral mucosa (as part of combination therapy).

Dosage Regimen

For oropharyngeal spray, administer the solution directly to the affected area.

For adults and children 12 years and older, use 4-8 sprays, 2-6 times daily.

For children 6 to 12 years old, use 4 sprays, 2-6 times daily.

For children 3 to 6 years old, the dose is 1 spray per 4 kg of body weight, with a maximum single dose of 4 sprays; administer 2-6 times daily.

For all patients, individualize the frequency of administration based on the severity of pain and inflammation.

For oral rinse solution, use 15 mL undiluted.

Rinse the mouth thoroughly for 30 seconds to 2 minutes, then expectorate the solution completely.

Repeat the rinse procedure 2-3 times daily, or as directed by a physician.

The maximum duration of continuous use without medical consultation is 7 days.

If symptoms persist beyond this period, discontinue use and consult a physician.

Avoid contact with eyes. In case of accidental contact, rinse thoroughly with water.

Adverse Reactions

Local reactions: rarely – dry mouth, burning sensation in the oral cavity; frequency unknown – numbness in the oral cavity.

Allergic reactions: infrequently – photosensitivity; rarely – sensitivity reactions, skin rash, skin itching; very rarely – angioedema, laryngospasm; frequency unknown – anaphylactic reactions.

Contraindications

Children under 3 years of age; children over 3 years of age (depending on the dosage form used); hypersensitivity to benzydamine.

With caution

Hypersensitivity to acetylsalicylic acid or other NSAIDs; bronchial asthma (including history).

Use in Pregnancy and Lactation

Should not be used during pregnancy and breastfeeding.

Pediatric Use

Contraindicated in children under 3 years of age; in children over 3 years of age – depending on the dosage form used.

Geriatric Use

There are no special instructions for limiting use in elderly patients.

Special Precautions

If there is an ulcerative lesion of the oropharyngeal mucosa, the patient should consult a doctor if symptoms persist for more than 3 days.

Not recommended for use in patients with hypersensitivity to acetylsalicylic acid or other NSAIDs.

Use with caution in patients with bronchial asthma, as bronchospasm may develop.

Storage Conditions

Store at 2°C (36°F) to 25°C (77°F). Keep in original packaging, protected from light. Keep out of reach of children.
