Pharmachologic effect

Mode of action - anti-allergic, antihistamine.

Pharmacodynamics

Fexofenadine hydrochloride is a blocker of H1-histamine receptors, virtually devoid of sedation. Fexofenadine is a pharmacologically active metabolite of terfenadine.

The antihistaminic effect of the drug manifests itself 1 hour after administration, reaches a maximum after 6 hours and lasts for 24 hours. After 28 days of admission, there is no development of tolerance. At oral intake of doses from 10 to 130 mg there is a linear dose-response relationship. For a 24-hour effectiveness of the drug (for allergic rhinitis), a dose of 120 mg is sufficient. In a dose of up to 240 mg, the drug does not cause changes in the QT interval.

Pharmacokinetics

Fexofenadine hydrochloride after oral administration is rapidly absorbed from the gastrointestinal tract, Tmax is 1-3 hours. The average value of Cmax after taking a dose of 120 mg is 289 ng / ml, and after taking a dose of 180 mg, approximately 494 ng / ml. Binding to plasma proteins is 60-70% (mainly with albumin and alpha1-glycoprotein). Does not penetrate the BBB. Fexofenadine is partially metabolized (5% of the dose).

Biphasic withdrawal. T1 / 2 after repeated administration - 11-15 hours. In patients with moderate (Cl creatinine 41-80 ml / min) and severe (11-40 ml / min) renal failure T1 / 2 increases by 59 and 72%, respectively; In patients on hemodialysis, T1 / 2 increases by 31%. Pharmacokinetics with a single and repeated use of fexofenadine (up to 120 mg twice a day) is linear.

Mostly (80%) is excreted with bile, up to 10% of the dose taken is excreted unchanged in urine.

Indications of the preparation Fexadin

Rarely (less than 1 case per 1000 prescriptions) - a feeling of fatigue, insomnia, nervousness, sleep disturbance.

In some cases - skin rash, hives, itching, and other hypersensitivity reactions (angioedema, dyspnea).

Interaction

When combined with erythromycin or ketoconazole, the concentration of fexofenadine in plasma increases 2-3 times. There is no significant influence on the increase in the QT interval. The intake of aluminum-or magnesium-containing antacids 15 minutes before fexofenadine administration leads to a decrease in the bioavailability of the latter (the time interval between their intake should be at least 2 hours). Does not interact with omeprazole.
