Rupafen Tablet: Each tablet contains Rupatadine fumarate INN equivalent to Rupatadine 10 mg
Rupatadine acts as a long-acting, non-sedative antagonist of histamine H1 receptors and also, antagonizes the platelet-activating factor (PAF). Both histamine and PAF causes bronchoconstriction and lead to an increase in the vascular permeability, acting as a mediator in the inflammatory process. This double mechanism of action gives Rupatadine a major clinical efficacy regarding agents that show an isolated antihistamine action. 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 TNF a in human mast cells and monocytes.
Rupatadine is rapidly absorbed after oral administration, with a tmax of approximately 0.75 hours. The mean Cmax was 2.6 ng/mL after a single oral dose of 10 mg and 4.6 ng/mL after a single oral dose of 20 mg. After a dose of 10 mg/day for 7 days, the mean Cmax was 3.8 ng/mL. The elimination half-life was 5.9 hours. The plasma proteins binding rate was 98.5-99 %.
Rupatadine is indicated for the symptomatic treatment of allergic rhinitis and urticaria.

USE IN PREGNANCY & LACTATION:
Use in pregnancy:There is no clinical data available on the exposure of Rupatadine during pregnancy. Studies in animals did not show direct or indirect damaging effects, which refer to the pregnancy, embryonic/fetal development, delivery or pre-natal development. Pregnant women should therefore not use Rupatadine, unless the potential benefit outweighs the potential risk for the infant.
Use in lactation: 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.
CYP3A4 inhibitors like erythromycin & ketoconazole inhibit both the presystemic and systemic metabolism of Rupatadine. Due to this Potential interaction, it is not recommended to use Rupatadine in combination with ketoconazole, macrolides or any other inhibitors of CYP3A4. Co-administration of Rupatadine and CNS depressants or alcohol may increase CNS depressant effect.
PATIENT WITH LIVER OR KIDNEY INSUFFICIENCY:
