Pharmacological properties

Fenistil - drops for adults with pronounced antihistamine properties. The tool has an anti-allergic effect, which helps to alleviate the condition of patients with various diseases of allergic origin.

The medication also has decongestant and antipruritic properties, which helps not only eliminate the manifestations of allergies, but also prevents their recurrence for a short period of time. The medicine has an effect rather quickly, does not have sedative properties, which worsen the condition of many patients when treated with other antihistamines.

Pharmacodynamics and pharmacokinetics

The medicine has an effect almost immediately after the penetration of the solution into the digestive tract. The active ingredient enters the systemic circulation and acts on histamines, which are produced in the body under the influence of allergens. As a result of blocking histamine receptors, tissue edema is eliminated, itching is relieved.

Many people note the complete elimination of itching, but even its relief significantly improves the condition. Patients talk about eliminating the burning sensation of the skin and mucous membranes.

The drug has other features:

• One of the important abilities of the remedy is the elimination of edema of the mucous membranes. With the development of allergies, it is possible that rhinitis or conjunctivitis can join, therefore, the effect on the mucous membranes helps to improve the condition.
• The action of the drug persists for a long period of time, which eliminates the need for repeated use of drops throughout the day.
• The first effect from the application is observed within 10-15 minutes after use.
• The agent is quickly absorbed in the body, absorption occurs in the small intestine, after which the ingredient enters the bloodstream and spreads throughout the body, affecting the production of histamines.
• The bioavailability of the drug is approximately 70%. The active substance of the composition binds well to plasma proteins, its maximum concentration in the blood is observed 2 hours after taking a single dosage of the drug.

The agent is well processed in the liver, decomposes into metabolites. When an organ is damaged, a slowdown in this process is observed, which somewhat worsens the effectiveness of the drug. The drug does not accumulate in tissues and organs, this reduces the risk of overdose with prolonged use.

After processing, the ingredients are excreted from the body with the help of the kidneys; a small part of the ingredients is evacuated with the feces.

Only 10% of the total dose of the active substance is evacuated unchanged, the rest is excreted in the form of metabolites. With damage to the genitourinary system, there is a deterioration in the excretion of drug components, which increases the risk of their accumulation in tissues and blood. As a result, an overdose may develop. Pharmacokinetic features may differ from patient to patient.
