Pharmacological properties

Pharmacodynamics

The active substance in the composition of Delorsin tablets is desloratadine, the primary active metabolite of loratadine. It has a long-term antihistamine effect on the body, due to a selective effect on peripheral H ₁ -histamine receptors.

Desloratadine inhibits a cascade of allergic inflammatory reactions, including the release of cytokines that mobilize the inflammatory response [such as interleukins (IL) - IL-4, IL-6, IL-8, IL-13] and pro-inflammatory chemokines [for example, RANTES (Regulated on Activation, Normal T Cell Expressed and Secreted)]. Inhibits the production of superoxide anions by activated polymorphonuclear neutrophils, chemotaxis and adhesion of eosinophils, the release of intercellular adhesion molecules (for example, P-selectin), immunoglobulin E (IgE) -mediated release of prostaglandin D ₂, histamine and cysteine cysteine.

Delorsin prevents the development and facilitates the course of hypersensitivity reactions, providing antipruritic and antiexudative action, reducing capillary permeability, preventing the development of tissue edema and smooth muscle spasm.

The drug does not affect the central nervous system (CNS), has almost no sedative effect (does not cause drowsiness) and does not change the speed of psychomotor reactions. Taking desloratadine does not prolong the QT interval on the electrocardiogram (ECG).

Delorsin begins to act within half an hour after oral administration, the therapeutic effect is observed for 24 hours.

Pharmacokinetics

• absorption: after oral administration in the digestive tract, desloratadine is well absorbed; in blood plasma is determined after half an hour, C _max (maximum concentration) on average reaches after 3 hours;
• distribution: desloratadine binds to plasma proteins at the level of 83–87%. Taking the drug for 2 weeks once a day at a dose of 5–20 mg in adult patients and adolescents did not cause clinically significant accumulation of desloratadine. The substance does not cross the blood-brain barrier (BBB). When Delorsin is taken once a day at a dose of 7.5 mg, its distribution is not affected by the simultaneous intake of food or grapefruit juice;
• Metabolism: The metabolic process takes place in the liver through hydroxylation, resulting in the formation of 3-OH-desloratadine combined with glucuronide. Desloratadine does not inhibit the cytochrome P ₄₅₀ 3A4 and 2D6 enzymes, nor is it an inhibitor or substrate of P-glycoprotein;
• excretion: a small part of the oral dose is excreted in the urine (less than 2%) and in the feces (less than 7%). T _1/2 (half-life) varies from 20 to 30 hours (an average of 27 hours).

Indications for use

Delorsin is used to treat seasonal or year-round allergic rhinitis with the aim of eliminating or relieving nasal congestion, sneezing, mucus discharge from the sinuses, itching in the nose and in the palate, lacrimation, itching and redness of the eyes.

Influence on the ability to drive vehicles and complex mechanisms

During therapy, it is important to take into account the likelihood of developing such negative side reactions as drowsiness and dizziness. When they appear, one should refrain from performing activities that require an increased concentration of attention and speed of psychomotor reactions, including driving vehicles or controlling complex mechanisms.

Application during pregnancy and lactation
