It further blocks the receptors of the platelet-activating factor (PAF) according to in vitro and in vivo studies.Rupatadine possesses anti-allergic properties such as the inhibition of the degranulation of mast cells induced by immunological and non-immunological stimuli, and inhibition of the release of cytokines, particularly of the tumor necrosis factors (TNF) in human mast cells and monocytes.andlt;brandgt;andlt;brandgt;Dosage and Administration of Duvent 10 mgandlt;brandgt;Rupatadine Tablet: The recommended dosage is 10 mg once daily, with or without food.

Rare: Palpitations, tachycardia.andlt;brandgt;andlt;brandgt;Pregnancy and Lactationandlt;brandgt;Pregnancy category B2 (by TGA, Australia). There is no clinical data available on the exposure of Rupatadine during pregnancy. Pregnant women should therefore not use Rupatadine, unless the potential benefit outweighs the potential risk for the fetus. No information is available, whether Rupatadine is excreted in the mother's milk. Therefore, it should not be used during lactation, unless the potential benefits for the mother justify the potential risk to the infant.andlt;brandgt;andlt;brandgt;Precautions and Warningsandlt;brandgt;Duvent 10 mg should be used with caution in patients with known prolongation of the QT interval, patients with uncorrected hypokalemia, and patients with ongoing proarrhythmic conditions, such as clinically significant bradycardia or acute myocardial ischemia. Rupatadine should be used with caution in elderly patients (65 years and older). As there is no clinical experience in patients with impaired kidney or liver function, the use of Rupatadine 10 mg tablets is at present not recommended in these patients.andlt;brandgt;andlt;brandgt;Overdose Effects of Duvent 10 mgandlt;brandgt;The most common adverse reaction was somnolence. If accidental ingestion of very high doses occurs, symptomatic treatment together with the required supportive measures should be given.andlt;brandgt;andlt;brandgt;Storage Conditionsandlt;brandgt;Store in cool and dry place below 30°C, protect from light and moisture. Keep out of reach of children.andlt;brandgt;andlt;brandgt;Use In Special Populationsandlt;brandgt;Elderly: Rupatadine should be used with caution in elderly. No information is available that indicates the requirement of any dose adjustment in this population.Children: Neither the safety nor the efficacy of Rupatadine has been established in patients less than 12 years of age.Patients with renal or hepatic insufficiency: Use of Rupatadine is not recommended in patients with renal or hepatic insufficiency. As no relevant clinical data is available.andlt;brandgt;andlt;brandgt;Drug Classesandlt;brandgt;Non-sedating antihistaminesandlt;brandgt;andlt;brandgt;Mode Of Actionandlt;brandgt;Duvent 10 mg is a long-acting, non-sedative antagonist of histamine H1-receptors. It also antagonizes the platelet activating factor (PAF). Both histamine and PAF cause broncho constriction which leads to an increase in the vascular permeability and act as a mediator in the inflammatory process. With the dual mode of action, Rupatadine shows better therapeutic effect than an isolated antihistamine. Rupatadine possesses other anti allergic properties such as the inhibition of the degranulation of mast cells induced by immunological and non immunological stimuli and inhibition of the release of cytokines, particularly of the tumor necrosis factor alpha (TNF α) in human mastocytes and monocytes.andlt;brandgt;andlt;brandgt;Pregnancyandlt;brandgt;There is no clinical data available on the exposure of Rupatadine during pregnancy. Pregnant women should therefore not use Rupatadine unless the potential benefit outweighs the potential risk for the infant.
