چکیده
IN THE TITLE COMPOUND (SYSTEMATIC NAME 8-chloro-11-{1-[(5-methyl-pyridin-3-yl)meth-yl]piperidin-4-yl-idene}-6,11-di-hydro-5H-benzo[5,6]cyclo-hepta-[1,2-b]pyridine), C26H26ClN3, the dihedral angle between the mean planes of the chloro-phenyl and cyclo-hepta-[1,2-b]pyridinyl rings fused to the cyclo-heptane ring is 56.6 (1)°. The mean planes of the cyclo-hepta-[1,2-b]pyridinyl and 5-methyl-pyridin-3-yl rings are twisted by 64.9 (4)°. The central piperizene group is in a slightly distorted chair configuration. A weak intra-molecular C-H⋯N inter-action is observed between the cyclo-hepta-[1,2-b]pyridinyl and piperidin-4-yl-idene moieties.

Lack of effects between rupatadine 10 mg and placebo on actual driving performance of healthy volunteers.
INTRODUCTION Rupatadine fumarate is a potent, selective, histamine H(1)-receptor antagonist and PAF inhibitor with demonstrated efficacy for the relief of allergic rhinitis. Rupatadine does not easily cross the blood-brain barrier and is believed to be non-sedating at therapeutic doses. Consequently, rupatadine should show no impairment on car driving. OBJECTIVE This study compared the acute ...
متن کاملAllergy, Asthma & Clinical Immunology
Background: Platelet-activating factor (PAF) is produced by most inflammatory cells and it is involved in inflammatory and allergic reactions. We aimed to assess the anti-PAF effects of rupatadine and levocetirizine in the upper airways. Findings: Healthy volunteers (HV, N = 10) and seasonal allergic rhinitis (SAR, N = 10) asymptomatic patients were treated out of the pollen season with either ...
متن کاملPharmacokinetics, Safety and Cognitive Function Profile of Rupatadine 10, 20 and 40 mg in Healthy Japanese Subjects: A Randomised Placebo-Controlled Trial
INTRODUCTION Rupatadine is a marketed second generation antihistamine, with anti-PAF activity, indicated for symptomatic treatment of allergic rhinitis and urticaria. This study was conducted to evaluate the pharmacokinetics (PK), pharmacodynamics (PD), safety and tolerability of rupatadine in healthy Japanese subjects after single and multiple oral doses. METHODS In this randomised, double-b...
متن کاملEffects of Rupatadine on Platelet- Activating Factor-Induced Human Mast Cell Degranulation Compared With Desloratadine and Levocetirizine (The MASPAF Study).
BACKGROUND AND OBJECTIVE Platelet-activating factor (PAF) is a lipid mediator involved in the pathophysiology of several allergic diseases, for example, in the amplification of mast cell (MC) activation in anaphylaxis. Rupatadine is an antihistamine with a demonstrated anti-PAF effect, although its capacity to inhibit PAF-induced MC degranulation has not been fully evaluated. Objectives: To comp...
متن کاملRupatadine in the treatment of chronic idiopathic urticaria: a double-blind, randomized, placebo-controlled multicentre study.
BACKGROUND Chronic urticaria is one of the most common and disturbing cutaneous condition. The treatment of chronic idiopathic urticaria (CIU) is still a challenge. Antihistamines are recommended as first-line treatment. Rupatadine is a new potent nonsedative anti-H1. OBJECTIVE To study rupatadine efficacy and safety for moderate to severe CIU treatment. METHODS This randomized, double-blin...
متن کاملRupatadine Protects against Pulmonary Fibrosis by Attenuating PAF-Mediated Senescence in Rodents
A similar immune response is implicated in the pathogenesis of pulmonary fibrosis and allergic disorders. We investigated the potential therapeutic efficacy and mechanism of rupatadine, a dual antagonist of histamine and platelet-activation factor (PAF), in bleomycin- (BLM-) and silica-induced pulmonary fibrosis. The indicated dosages of rupatadine were administered in rodents with bleomycin or...
