Participants were aged ≥ 18 years, with diagnosis of PAR and a Total 4 Nasal Symptom Score (T4NSS) ≥ 5. We evaluated the T4NSS and Total 5 Symptom Score (T5SS) for 28 days of treatment, the responder proportion (50% and 75% response), and the time to response.\nRESULTS: Efficacy data from 1486 patients were analysed: 585 received placebo, 682 rupatadine 10 mg, and 219 rupatadine 20 mg. Compared with placebo, rupatadine promoted greater symptom improvements and higher responder proportions (50% and 75% response) for T4NSS and T5SS over 28 days. Symptom improvements and responder proportions were higher in the rupatadine 20 mg group vs the 10 mg group. The time to response was shorter in the rupatadine 20 mg group vs the 10 mg group for T4NSS (16 and 9 days for the 50% and 75% responses, respectively) and for T5SS (13 and 8 days for the 50% and 75% responses, respectively).\nCONCLUSIONS: Rupatadine was efficacious in reducing allergic rhinitis symptoms, showing high responder proportions. The faster and stronger effect of rupatadine 20 mg may suggest its use in patients with severe PAR or not responding to the standard dose.","tracks":[{"project":"chenxin_473849_800_3","denotations":[{"id":"T1","span":{"begin":243,"end":270},"obj":"DP"},{"id":"T2","span":{"begin":78,"end":105},"obj":"DP"},{"id":"T3","span":{"begin":272,"end":275},"obj":"DP"},{"id":"T4","span":{"begin":394,"end":397},"obj":"DP"},{"id":"T5","span":{"begin":512,"end":515},"obj":"DP"},{"id":"T6","span":{"begin":1554,"end":1557},"obj":"DP"},{"id":"T7","span":{"begin":19,"end":29},"obj":"CI"},{"id":"T8","span":{"begin":173,"end":183},"obj":"CI"},{"id":"T9","span":{"begin":420,"end":430},"obj":"CI"},{"id":"T10","span":{"begin":803,"end":813},"obj":"CI"},{"id":"T11","span":{"begin":829,"end":839},"obj":"CI"},{"id":"T12","span":{"begin":870,"end":880},"obj":"CI"},{"id":"T13","span":{"begin":1074,"end":1084},"obj":"CI"},{"id":"T14","span":{"begin":1157,"end":1167},"obj":"CI"},{"id":"T15","span":{"begin":1493,"end":1503},"obj":"CI"},{"id":"T17","span":{"begin":53,"end":60},"obj":"CI"},{"id":"T18","span":{"begin":450,"end":457},"obj":"CI"},{"id":"T19","span":{"begin":790,"end":797},"obj":"CI"},{"id":"T20","span":{"begin":861,"end":868},"obj":"CI"},{"id":"T21","span":{"begin":1356,"end":1366},"obj":"CI"}],"attributes":[{"subj":"T1","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T2","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T3","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T4","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T5","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T6","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T7","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T8","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T9","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T10","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T11","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T12","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T13","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T14","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T15","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T17","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T18","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T19","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T20","pred":"source","obj":"chenxin_473849_800_3"},{"subj":"T21","pred":"source","obj":"chenxin_473849_800_3"}]},{"project":"yangbin123xm_800_3","denotations":[{"id":"T1","span":{"begin":78,"end":105},"obj":"DP"},{"id":"T10","span":{"begin":803,"end":813},"obj":"CI"},{"id":"T11","span":{"begin":829,"end":839},"obj":"CI"},{"id":"T12","span":{"begin":870,"end":880},"obj":"CI"},{"id":"T13","span":{"begin":1074,"end":1084},"obj":"CI"},{"id":"T14","span":{"begin":1157,"end":1167},"obj":"CI"},{"id":"T15","span":{"begin":1493,"end":1503},"obj":"CI"},{"id":"T16","span":{"begin":53,"end":60},"obj":"CI"},{"id":"T18","span":{"begin":450,"end":457},"obj":"CI"},{"id":"T19","span":{"begin":790,"end":797},"obj":"CI"},{"id":"T2","span":{"begin":243,"end":270},"obj":"DP"},{"id":"T20","span":{"begin":861,"end":868},"obj":"CI"},{"id":"T3","span":{"begin":272,"end":275},"obj":"DP"},{"id":"T4","span":{"begin":394,"end":397},"obj":"DP"},{"id":"T5","span":{"begin":512,"end":515},"obj":"DP"},{"id":"T6","span":{"begin":1554,"end":1557},"obj":"DP"},{"id":"T7","span":{"begin":19,"end":29},"obj":"CI"},{"id":"T8","span":{"begin":173,"end":183},"obj":"CI"},{"id":"T9","span":{"begin":420,"end":430},"obj":"CI"},{"id":"T21","span":{"begin":1356,"end":1366},"obj":"CI"}],"attributes":[{"subj":"T1","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T10","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T11","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T12","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T13","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T14","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T15","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T16","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T18","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T19","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T2","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T20","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T3","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T4","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T5","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T6","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T7","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T8","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T9","pred":"source","obj":"yangbin123xm_800_3"},{"subj":"T21","pred":"source","obj":"yangbin123xm_800_3"}]}],"config":{"attribute
