Pharmacological properties
Pharmacodynamics
Benzydamine hydrochloride - the active substance of the drug, is an NSAID (non-steroidal anti-inflammatory agent), a derivative of indazole without a carboxyl group. Due to the absence of a carboxyl group, the substance is a weak base (most NSAIDs are among weak acids), has a high lipophilicity, and penetrates well into the inflammatory focus along a pH gradient (where the pH is lower), in which it accumulates in therapeutic concentrations.
Benzydamine hydrochloride has anti-inflammatory and local analgesic effects, has antifungal and antiseptic (against a wide range of microorganisms) properties.
The anti-inflammatory effect of the substance is based on a decrease in capillary permeability, stabilization of cell membranes due to inhibition of biosynthesis and inactivation of cytokines, prostaglandins, bradykinin, histamine, complement factors and other non-specific damaging endogenous factors.
The action of benzydamine hydrochloride is aimed at suppressing the production of pro-inflammatory cytokines, in particular tumor necrosis factor-α (TNF-α) and, to a somewhat lesser extent, interleukin-lβ (IL-lβ).
Benzydamine can be classified as a cytokine-suppressing anti-inflammatory drug because its main feature is that it exhibits potent inhibition of pro-inflammatory cytokines, while being a weak inhibitor of prostaglandin biosynthesis.
The local anesthetic effect of the substance is based on the structural features of its molecule, similar to local anesthetics, the analgesic effect is based on an indirect decrease in the concentration of biogenic amines with algogenic properties, and an increase in the pain sensitivity threshold of the apparatus. Benzydamine also blocks the interaction of bradykinin and tissue receptors, increases the pain threshold and restores microcirculation in the inflammatory focus.
The antibacterial effect of benzydamine hydrochloride is due to its rapid penetration through the membranes of microorganisms, which leads to damage to cellular structures, disruption of metabolic processes and damage to cell lysosomes.
The substance has antifungal effect against twenty strains of Candida albicans and non-albicans strains. The mechanism of action is based on structural modifications of the cell wall of fungi and their metabolic chains, which, as a result, prevents their reproduction.
Pharmacokinetics
When applied topically, benzydamine hydrochloride is absorbed well through the mucous membranes, the substance quickly penetrates into inflamed tissues, and is found in blood plasma in an amount that is insufficient for the development of systemic effects.
Excretion is carried out mainly by the kidneys and through the intestines in the form of conjugation products or metabolites.
Indications for use
Benzydamine is prescribed for the symptomatic treatment of pain syndrome accompanying various etiologies of inflammation:
- oral cavity: periodontal disease, glossitis, gingivitis, stomatitis (including conditions after radiation therapy);
- ENT organs: laryngitis, pharyngitis, tonsillitis;
- conditions after injuries and surgical interventions (jaw fractures, tonsillectomy), treatment / extraction of teeth;
- calculous inflammation of the salivary glands;
- candidiasis of the oral mucosa (in combination with other drugs).
For the treatment of diseases of infectious and inflammatory etiology, in which a systemic approach is required, Benzydamine is used as part of a combination therapy.
Contraindications
Absolute:
- age up to 12 years;
- pregnancy and lactation;
- individual intolerance to the components of the drug.
Relative (Benzydamine is prescribed under medical supervision):
- bronchial asthma (including a burdened history);
- individual intolerance to acetylsalicylic acid or other NSAIDs.
Benzydamine, instructions for use: method and dosage
A solution of Benzydamine is applied topically as a gargle, after a meal.
For rinsing the mouth or throat, patients of all age groups (including the elderly) are shown to use 15 ml of solution 2-3 times a day. Rinsing is carried out for 20-30 seconds, after which the drug should be spat out.
In cases where the use of an undiluted solution leads to a burning sensation, the drug is diluted with water in a ratio of 1 ÷ 1.
The maximum duration of therapy is 7 days. If at the end of this period the condition does not improve or the development of new symptoms is noted, you should consult your doctor.
Side effects
During the period of use of Benzydamine, the following undesirable side effects may develop (> 10% - very often;> 1% and 0.1% and 0.01% and <0.1% - rarely; <0.01% - very rarely):
- local reactions: rarely - burning sensation in the oral cavity, xerostomia; with an unspecified frequency - a feeling of numbness in the oral cavity;
- allergic reactions: infrequently - photosensitivity; rarely - skin rash, hypersensitivity reactions, pruritus; very rarely - laryngospasm, angioedema; with an unknown frequency - anaphylactic reactions;
- others: with an unknown frequency - laryngospasm.
Overdose
There have been no reports of an overdose of Benzydamine. If you use the drug in accordance with the instructions, the development of an overdose is unlikely.
If Benzydamine is swallowed, the following symptoms may appear: respiratory depression, abdominal cramps, vomiting, convulsions, ataxia, tachycardia, fever, anxiety, hallucinations, fear.
Therapy: symptomatic. It is necessary to cleanse the stomach by induction of vomiting or rinse it using a gastric tube (the procedure should be carried out under the supervision of a doctor). The patient's condition must be monitored. Supportive therapy and ensuring the required level of hydration are indicated. No antidote known.
special instructions
If hypersensitivity reactions develop during therapy with Benzydamine, it is necessary to stop using the drug and seek medical advice.
In some patients, ulcers in the mouth and throat may indicate a more serious condition. If symptoms persist within 3 days of therapy, you should consult a doctor.
The composition of Benzydamine contains parahydroxybenzoates, which can lead to the development of allergic reactions.
Drivers of vehicles should take into account that 1 dose of Benzydamine contains 1200 mg of 95% alcohol.
Athletes should take into account that when using drugs containing ethanol, the results of anti-doping tests for the maximum permissible content of ethanol in the blood (according to the standards established by some sports federations) may turn out to be positive.
