Relief of symptoms associated with allergic rhinitis and urticaria.
Composition:
1 tabl contains 5 mg desloratadine. 1 ml oral solution contains 0.5 mg desloratadine; the solution contains sorbitol.
Action:
Desloratadine is a sedative, long-acting histamine antagonist with selective antagonistic activity towards peripheral H-receptors1. Antiallergic properties of desloratadine include inhibiting the release of cytokines inducing an inflammatory response (i.e., IL-4, IL-6, IL-8 and IL-13) from human mast cells and basophils, as well as inhibiting the expression of P-selectin on the surface of endothelial cells. In patients with allergic rhinitis, desloratadine is effective in relieving symptoms such as sneezing, pruritus, nasal discharge, as well as itching, tearing and redness of the eyes and pruritis. In patients with urticaria, it reduces the number and size of urticarial lesions and soothes pruritus. Desloratadine does not easily penetrate to o.u.n., so that it practically does not exert a calming effect, does not cause drowsiness or does not affect psychomotor activity. Desloratadine is rapidly absorbed from the gastrointestinal tract (about 30 min), reaching Cmax after about 3 h. Plasma protein binding is 83-87%. T0,5 is 27 hours.
Contraindications:
Hypersensitivity to des loratadine, loratadine or to any of the excipients.
Precautions:
Use with caution in patients with severe renal impairment. The efficacy and safety of desloratadine in the form of in children aged <12 years. The efficacy and safety of desloratadine oral solution in infants up to 1 year have not been determined. Desloratadine has not been studied in children <2 years of age who have a slow metabolism. The safety of desloratadine in children from 2 to 11 years of age who have a slowed metabolism is the same as in children with normal metabolism. Due to the content of sorbitol, the oral solution should not be used in patients with fructose intolerance, glucose-galactose malabsorption or sucrase-isomaltase deficiency.
Pregnancy and lactation:
The safety of the medicine during pregnancy has not been established - use is not recommended. Desloratadine is excreted in breast milk - use is not recommended during breastfeeding.
