Primary Outcome Measures:
  • AUC of TSS [ Time Frame: 14 days ]
    The area under curve (AUC) of the total symptom score (TSS) since basal visit to D14 visit according to the patient's assessment

Secondary Outcome Measures:
  • Change in TSS. Reflective symptoms [ Time Frame: 14 days ]
    Change in the reflective total score on symptom scale on D14 visit and day7 visit versus D0 visit (baseline) according to the patient´s assessment on the previous 12 hours.

  • Change in TSS. Instantaneous score [ Time Frame: 14days ]
    Change in the total score on symptom scale on D7 and D14 visits versus D0 visit (baseline) according to the patient's assessment (instantaneous score).

  • Change in total nasal symptom score (TNSS) [ Time Frame: 14 days ]
    Change in nasal symptom score on symptom scale on D7 and D14 visits versus D0 visit (baseline) according to the patient's and investigator's assessment

  • •Change in total non-nasal symptom score (TNNSS) [ Time Frame: 14 days ]
    Change in non-nasal symptom score on symptom scale on D7 and D14 visits versus D0 visit (baseline) according to the patient's and investigator's assessment

  • VAS of discomfort [ Time Frame: 14 days ]
    Overall assessment of discomfort caused by allergic rhinitis using a visual analog scale (VAS) on D7 and D14 versus D0.

  • CGI [ Time Frame: 14 days ]
    Investigator's overall clinical impression (CGI)

  • •Allergic rhinitis (AR) quality of life (QoL) questionnaire (RQLQ) [ Time Frame: 14 days ]
    Quality of Life change versus baseline.

  • responde's rate [ Time Frame: 14 days ]
    Patients were analysed based on their total symptoms score decrease from baseline (<25%, 25%-50%, 50%-75%, >75%).

  • safety assessment [ Time Frame: 14 days ]
    comparison of the adverse event profiles throughout the course of the study, ECGs and safety blood tests on D0 and D14.

Ages Eligible for Study:   12 Years to 70 Years   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • The study disease was diagnosed on the basis of clinical criteria: Nasal symptoms (presence of nasal blockage, sneezing, nasal itching and rhinorrhea) and non-nasal symptoms (ocular itching, lacrimation, itching of ears and/or palate and ocular redness), as well as the skin prick test performed at the time of selection or within the year prior to entering.
  • Patients with history of Seasonal Allergic Rhinitis, positive skin prick test and symptoms were included if they were between 12 and 70 years old, gave their informed consent, attended the required visits scheduled and also underwent a complete medical examination..

Exclusion Criteria:

  • Patients were excluded if they had a significant nasal abnormality which could interfere with the aim of the study, acute or chronic sinusitis, asthma or any condition, disease or hypersensitivity that could be harmed.
  • Patients were not allowed to take forbidden medications or not comply the study requirements.
  • Patients who were currently participating in or had participated in another clinical trial within the previous three months or were planning to travel outside of the study area during the course of the study were excluded.
  • Pregnant or breast-feeding women were also excluded.
  • Women of childbearing potential had a pregnancy test done
