When administered in a therapeutic dose, loratadine is rapidly absorbed from the gastrointestinal tract and is almost completely metabolized in the body. Cmax of loratadine in plasma is reached after 1-1.3 h, the main active metabolite, descarboethoxyloratadine, after about 2.5 h. With simultaneous ingestion, the bioavailability of loratadine and descarboethoxyloratadine increases by about 40% and 15%, respectively, the time to reach Cmax increased by about 1 h, its values ​​for these substances remained unchanged. Plasma protein binding of loratadine is high - about 98%, the active metabolite is less pronounced. On average, T1 / 2 loratadine is 8.4 h, descarboethoxyloratadine - 28 h (8.8-92 h). About 80% of loratadine is excreted in the form of metabolites in the urine and feces in equal proportions within 10 days, about 27% in the urine during the first days.
