Eligibility Criteria
-----------------
Inclusion Criteria: Patients of both sexes aged from 18 to 60 inclusively. Patients with body temperature >37,8°C at the moment of examination by the doctor; with at least one catarrh symptom (cough, rhinitis, sore throat) and one intoxication symptom (myalgia, fever/hyperhidrosis, malaise, weakness, headache) during seasonal influenza morbidity. Diagnosed influenza confirmed by express diagnostics (presence of antigens of influenza virus in nasal passages epithelium and proved by QuickVue immunological test). The possibility to start therapy within 24 hours after the onset of the first influenza symptoms. Signed Informed Consent form for participation in the study. Exclusion Criteria: Patients aged below 18 years and above 60 years. Suspected invasive bacterial infection or presence of severe disease requiring use of antibacterial drugs (including sulfanilamides). Vaccination against influenza prior to epidemic season onset. Medical history of polyvalent allergy. Allergy/ intolerance to any of the components of medications used in the treatment. Exacerbation or decompensation of chronic diseases affecting the patient's ability to participate in the clinical trial. Chronic renal insufficiency. Intake of medicines listed in the section Prohibited concomitant treatment for 15 days prior to the inclusion in the trial. Pregnancy, breast feeding, unwillingness to keeping to contraception method during the study. Drug addiction, alcohol usage in the amount over 2 units of alcohol per day. Patients, who from investigator's point o view, will fail to comply with the observation requirements of the trial or with the intake regimen of the investigated medicines. Participation in other clinical trials in the course of 1 month prior to the inclusion in the trial. The patient is related to the research personnel of the investigative site, who are directly involved in the trial or are the immediate relative of the reseacher. The immediate relatives includes husband / wife, parents, children, brothers (or sisters), regardless of whether they are natural or adopted. The patient works for OOO NPF Materia Medica Holding (i.e. is the company's employee, temporary contract worker or designated official responsible for carrying out the research) or the immediate relative.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Patients With Normal Body Temperature | Axillary temperature (morning and evening) decline to or below 37.0 ºС (without subsequent increase during ≥24 h) | Day 1 to Day 5 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Patients With Resolution of Influenza Symptoms | Assessment of the proportion of subjects with no clinical symptoms of the disease (fever, common and respiratory symptoms) at Study Day 7 (Visit 3). The severity of influenza symptoms was assessed by a physician with 0 to 3 point scale, where 0 means no symptom, 1=mild symptom, 2=moderate symptom, and 3=severe symptom | on the day 7 of the observation | 
| Time to Resolution of the Influenza | Time to resolution was considered as time to the absence of any flu symptom. Absence of symptoms was considered as axillary temperature decline to or below 37.0 ºС without subsequent rise, resolution of the common and respiratory symptoms. The duration of a symptom was defined by physician recorded presence/absence of the symptoms during a physical examination at Day 1 to Day 7. | Day 1 to Day 7 | 
| Mean Body Temperature | The axillary temperature was assessed during a physical examination at Day 1, 3 and 7; axillary temperature was assessed in degrees (Celsius, °С) | on days 1, 3 and 7 of the observation | 
| Severity of Influenza Symptoms (Total Score of the Common Symptoms and Respiratory Symptoms) | The severity of influenza symptoms was assessed during a physical examination at Day 1, 3 and 7; common (10 symptoms) and respiratory (5 symptoms) symptom's total score was assessed with using the point scale: 0=No symptom; 1=Mild symptom; 2=Moderate symptom ; 3=Severe symptom. The Common Symptoms total score ranged from 0 (no symptoms) to 30 (severe symptoms). The Respiration Symptoms total score ranged from 0 (no symptoms) to 15 (severe symptoms) | on days 1, 3 and 7 of the observation | 
| The Number of the Antipyretic Intake | A subject recorded the number of antipyretic intake in patient diary. | Day 1 to Day 5 | 
| Change in the Patient's Quality of Life. | The quality of life was assessed in influenza patients at baseline and at the end of the treatment period using the European Quality of Life Questionnaire (EQ5D) measuring the health status by five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression (each dimension is assessed by 1 to 3 point scale; the minimum score 5 points refers to the best status, 15 points refers to the worst status). | Day 7 vs. Day 1 | 
| Change in the Subjective Health Status | The patient subjective health status assessment was based on Visual Analogue Scale - VAS). VAS includes a rating of current health status from 0 (worst) to 100 (best). | Day 7 vs. Day 1 | 
| Percentage of Patients With Complications of the Influenza | Pneumonia, sinusitis, otitis media are examples of the influenza complications | Day 1 to Day 7 |
