Pharmacological action
Desal – a blocker of histamine H1 receptors (long-acting). It is the primary active metabolite of loratadine. Inhibits the release of histamine and C4 leukotriene from mast cells. Prevents development and facilitates the course of allergic reactions. It has anti-allergic, antipruritic and anti-exudative action. Reduces capillary permeability, prevents the development of tissue edema, relieves spasm of smooth muscles. It practically does not have a sedative effect and, when taken at a dose of 7.5 mg, does not affect the rate of psychomotor reactions. In comparative studies of desloratadine and loratadine, there were no qualitative or quantitative differences in the toxicity of the two drugs in comparable doses (taking into account the concentration of desloratadine).
Pharmacokinetics
After ingestion, it begins to be determined in plasma after 30 minutes. Food does not affect distribution. Bioavailability is proportional to the dose in the range from 5 mg to 20 mg. Plasma protein binding is 83-87%. It does not cross the blood-brain barrier (BBB). Intensively metabolized in the liver by hydroxylation with the formation of 3-OH-desloratadine, combined with glucuronide, only a small portion of the oral dose is excreted by the kidneys (less than 2%) and with feces (less than 7%).
