Pharmacological effect

Loratadine - a blocker of histamine H1 receptors (long-acting). Inhibits the release of histamine and leukotriene C4 from mast cells. Prevents the development and facilitates the course of allergic reactions. It has antihistamine, antiallergic, antipruritic and anti-exudative action. Reduces capillary permeability, prevents the development of tissue edema, relieves spasm of smooth muscles. The antiallergic effect develops after 30 minutes, reaches a maximum after 8 to 12 hours and lasts 24 hours. It does not affect the central nervous system and does not cause addiction (because it does not penetrate the blood-brain barrier).

Pharmacokinetics

Quickly and completely absorbed in the digestive tract. Tmax - 1.3-2.5 h; food intake slows it down by 1 hour. Cmax in the elderly increases by 50%, with alcoholic liver damage, depending on the severity of the disease. Communication with plasma proteins - 97%. Metabolized in the liver to form the active metabolite of descarboethoxyloratadine with the participation of cytochrome P450, CYP3A4 and, to a lesser extent, CYP2D6 isoenzymes. Equilibrium concentration of loratadine and metabolite in plasma is achieved on the 5th day of administration. Does not penetrate the BBB. T1 / 2 loratadine - 3-20 hours (average 8.4 hours), active metabolite - 8.8-92 hours (average 28 hours); in elderly patients, respectively - 6.7-37 hours (average 18.2 hours) and 11-38 hours (17.5 hours). When alcoholic liver damage T1 / 2 increases depending on the severity of the disease. Excreted by the kidneys and with bile. In patients with chronic renal failure and during hemodialysis, the pharmacokinetics are virtually unchanged.
