Antiallergic activity of loratadine a non sedating antihistamine


Persistent allergic rhinitis is defined as the presence of symptoms for 4 days or more per week and for more than 4 weeks. In two placebo-controlled six week trials in patients with chronic idiopathic urticaria, Neoclarityn was effective in relieving pruritus and decreasing the size and number of hives by the end of the first dosing interval. No clinically relevant changes in desloratadine plasma concentrations were observed in multiple-dose ketoconazole and erythromycin interaction trials. This lack of receptor selectivity is the basis of the poor tolerability profile of some of these agents, especially when compared with the second-generation H1-antihistamines. They are effective in the relief of allergic symptoms, but are typically moderately to highly potent muscarinic acetylcholine receptor anticholinergic antagonists as well. In the single-dose study, the exposure to desloratadine was approximately 2 and 2. Desloratadine does not inhibit CYP3A4 in vivo, and in vitro studies have shown that the medicinal product does not inhibit CYP2D6 and is neither a substrate nor an inhibitor of P-glycoprotein. Since histamine release is a causal factor in all urticarial diseases, desloratadine is expected to be effective in providing symptomatic relief for other urticarial conditions, in addition to chronic idiopathic urticaria, as advised in clinical guidelines. The most common adverse effect is sedation; this "side-effect" is utilized in many OTC sleeping-aid preparations. Biotransformation The enzyme responsible for the metabolism of desloratadine has not been identified yet, and therefore, some interactions with other medicinal products can not be fully excluded. Chronic idiopathic urticaria was studied as a clinical model for urticarial conditions, since the underlying pathophysiology is similar, regardless of etiology, and because chronic patients can be more easily recruited prospectively. In each trial, the effects were sustained over the 24 hour dosing interval. Pharmacodynamic effects Desloratadine has demonstrated antiallergic properties from in vitro studies. The lack of carcinogenic potential was demonstrated in studies conducted with desloratadine and loratadine. There is no evidence of clinically relevant medicine accumulation following once daily dosing of desloratadine 5 mg to 20 mg for 14 days. Symptoms Based on a multiple dose clinical trial, in which up to 45 mg of desloratadine was administered nine times the clinical dose , no clinically relevant effects were observed. Paediatric population The efficacy of Neoclarityn tablets has not been clearly demonstrated in trials with adolescent patients 12 through 17 years of age. Following their discovery, the first-generation H1-antihistamines were developed in the following decades. Other antihistamines for systemic use, ATC code: No clinically relevant changes in desloratadine plasma concentrations were observed in multiple- dose ketoconazole and erythromycin interaction trials. Desloratadine is well absorbed with maximum concentration achieved after approximately 3 hours; the terminal phase half-life is approximately 27 hours. In addition to the established classifications of seasonal and perennial, allergic rhinitis can alternatively be classified as intermittent allergic rhinitis and persistent allergic rhinitis according to the duration of symptoms. Intermittent allergic rhinitis is defined as the presence of symptoms for less than 4 days per week or for less than 4 weeks. R06A X27 Mechanism of action Desloratadine is a non-sedating, long-acting histamine antagonist with selective peripheral H1-receptor antagonist activity. Renally impaired patients The pharmacokinetics of desloratadine in patients with chronic renal insufficiency CRI was compared with that of healthy subjects in one single-dose study and one multiple dose study. The greatest amelioration was seen in the domains of practical problems and daily activities limited by symptoms. The clinical relevance of these observations remains to be confirmed.

There is no evidence of clinically relevant medicine accumulation following once daily dosing of desloratadine 5 mg to 20 mg for 14 days. Neoclarityn effectively controlled symptoms for 24 hours. Desloratadine does not inhibit CYP3A4 in vivo, and in vitro studies have shown that the medicinal product does not inhibit CYP2D6 and is neither a substrate nor an inhibitor of P-glycoprotein. Desloratadine effectively controlled symptoms for 24 hours. Weight increased Paediatric population Other undesirable effects reported during the post-marketing period in paediatric patients with an unknown frequency included QT prolongation, arrhythmia, bradycardia, abnormal behaviour, and aggression. Neoclarityn given at a single daily dose of 7. In another study, grapefruit juice had no effect on the disposition of desloratadine. Pharmacological properties Pharmacotherapeutic group: Desloratadine does not readily penetrate the central nervous system. This percentage may vary according to ethnic background. This is due to their relative lack of selectivity for the H1-receptor and their ability to cross the blood-brain barrier. This lack of receptor selectivity is the basis of the poor tolerability profile of some of these agents, especially when compared with the second-generation H1-antihistamines. Desloratadine does not readily penetrate the central nervous system. Since histamine release is a causal factor in all urticarial diseases, desloratadine is expected to be effective in providing symptomatic relief for other urticarial conditions, in addition to chronic idiopathic urticaria, as advised in clinical guidelines. Symptomatic and supportive treatment is recommended. Intermittent allergic rhinitis is defined as the presence of symptoms for less than 4 days per week or for less than 4 weeks.
