Desloratadine is a new, selective, H(1)-receptor antagonist that also has anti-inflammatory activity. In vitro studies have shown that desloratadine inhibits the release or generation of multiple inflammatory mediators, including IL-4, IL-6, IL-8, IL-13, PGD(2), leukotriene C(4), tryptase, histamine, and the TNF-alpha-induced chemokine RANTES. Desloratadine also inhibits the induction of cell adhesion molecules, plateletactivating factor-induced eosinophil chemotaxis, TNF-alpha-induced eosinophil adhesion, and spontaneous and phorbol myristate acetate-induced superoxide generation in vitro. In animals desloratadine had no effect on the central nervous, cardiovascular, renal, or gastrointestinal systems. Desloratadine is rapidly absorbed, has dose-proportional pharmacokinetics, and has a half-life of 27 hours. The absorption of desloratadine is not affected by food, and the metabolism and elimination are not significantly affected by the subject's age, race, or sex. There are no clinically relevant interactions between desloratadine and erythromycin, ketoconazole, or grapefruit juice. Desloratadine is not a significant substrate of the P-glycoprotein transport system. Once daily administration of desloratadine rapidly reduces the nasal and nonnasal symptoms of seasonal allergic rhinitis, including congestion. In patients with seasonal allergic rhinitis and concomitant asthma, desloratadine treatment was also associated with significant reductions in total asthma symptom score and use of inhaled beta(2)-agonists. Use of desloratadine in patients with chronic idiopathic urticaria was associated with significant reductions in pruritus, number of hives, size of the largest hive, and interference with sleep and daily activities. Clinical experience in over 2300 patients has shown that the adverse event profile of desloratadine is similar to that of placebo; desloratadine has no clinically relevant effects on electrocardiographic parameters, does not impair wakefulness or psychomotor performance, and does not exacerbate the psychomotor impairment associated with alcohol use.

We have planned to demonstrate histopathologic effects of mid- or long-term oral use of desloratadine and cetirizine HCl molecules on middle ear mucosa of rats. Thirty-six rats were randomized equally into six groups. Desloratadine groups received once daily doses of 1 mg/ml desloratadine for 30 (D30 Group) or 60 (D60 Group) days. The Cetirizine study groups were given once daily doses of 1 mg/ml cetirizine for 30 (S30 Group) or 60 (S60 Group) days. Control groups were given 2 cc physiologic saline using orogastric gavage method through a 12 G gavage catheter for 30 (K30 Group) or 60 (K60) days. At the end of 30 days, D30, S30 and K30 Groups were sacrificed. Tissue samples harvested from groups were evaluated between 1 and 4 Grades for histological characteristics of middle ear canal, eardrum, middle ear epithelium and connective tissue, edema, vascular congestion and inflammatory cells. In the control group no pathological finding was encountered in rats sacrificed on 30 and 60 days. No statistical difference was observed when groups were compared on external ear epithelial tissue, external ear sebaceous gland, middle ear inflammation, and middle ear capillary dilatation both on 30 and 60 days. Tympanic membrane collagen was more evident in D30 and D60 groups when compared with C30 and C60 groups. Comparison of histopathological grading results between 30 and 60 days revealed no significant changes. In conclusion, oral intake of cetirizine and desloratadine preparations has effects of tympanic membrane collagen, degrees of edema and vascular congestion being more prominent with desloratadine molecule.
