The emergence of tolerance with repeated use is not noted.
It has no sedative, cholino- and adrenolytic effects.
It does not lead to a change in the function of calcium / potassium channels, the QT interval when used in therapeutic doses.
Pharmacokinetics
After oral administration, fexofenadine hydrochloride is rapidly absorbed from the gastrointestinal tract, reaching Cmax (maximum concentration) in 1-3 hours. The average Cmax after taking 120 and 180 mg is approximately 427 and 494 ng / ml, respectively.
Plasma protein binding ranges from 60 to 70% (mainly with albumin and alpha1-glycoprotein). It does not penetrate the blood-brain barrier.
T1 / 2 (half-life) after repeated administration of fexofenadine - 14.4 hours. In moderate and severe renal failure (creatinine clearance 41–80 and 11–40 ml / min), T1 / 2 increases by 59 and 72%, respectively; in patients on hemodialysis - by 31%.
