Abstract

To evaluate the effect of therapy using modern antihistamines on the condition and severity of symptoms in adult patients with exacerbation of AR caused by plant pollen (seasonal) (SAR) and the development of ARVI. An observational study was conducted at the Department of Otorhinolaryngology of the Evdokimov Moscow State University of Medicine and Dentistry of the Ministry of Health of the Russian Federation from April to August 2021. Included are patients of both sexes aged 18 to 65 years with a previously (at least 1 year ago) verified diagnosis of mild and moderate acute SAR in the acute stage, who sought medical help for ARVI. All patients were prescribed therapy with the inclusion of a drug belonging to the pharmacological group of antihistamines of the 2nd generation (a course of 14 days). In addition, patients received symptomatic ARVI therapy according to indications, including nasal decongestants (as needed), antipyretic and antitussive drugs. Based on the data obtained, it was possible to prove that the use of modern antihistamines in patients comorbid with AR and ARVI has a pronounced therapeutic effect. Theoritin provides a therapeutic effect at an early stage in relation to nasal and non-nasal symptoms of SAR/ARVI, and also quickly improves the quality of life of patients, which makes its use promising for the treatment of ARVI against the background of AR. The drug has an antihistamine activity comparable to cetirizine and surpasses it in its ability to suppress an allergic inflammatory reaction, for example on the skin, as well as in the duration of preservation of the antihistamine effect. The presented results indicate the effectiveness of theoritin and cetirizine in the treatment of patients with seasonal exacerbation of allergic rhinitis, comorbid for acute respiratory viral infections.
