Brief Summary:
Recently, a new clinical presentation called "long covid" has been reported, for patients with symptoms lasting for more than 4 weeks from the onset of the disease. Typically, the symptoms comprise dyspnea, cough, headache, arthralgia, fever, abdominal pain, asthenia and skin manifestations This project aims to evaluate the efficacy of Montelukast in improving the quality of life associated with respiratory symptoms in patients with persistent COVID-19 symptoms. The main objective is to compare the efficacy of low-dose Montelukast versus placebo to improve respiratory symptoms in patients with persistent COVID-19 symptoms.

Primary Outcome Measures :
  1. COP Assessment Test Scale (CAT) [ Time Frame: 7, 14, 21 and 28 days ]
    The COPD Assessment Test (CAT) is a questionnaire for people with COPD, designed to measure the impact of COPD on a person's life, and how this changes over time.

Secondary Outcome Measures :
  1. 1min sit-to-stand test [ Time Frame: 14 and 28 days ]
    Exercise capacity: number of repetitions performed in the 1min sit-to-stand test

  2. O2 desaturation [ Time Frame: 14 and 28 days ]
    O2 desaturation ≥ 4% with effort (1min sit-to-stand test)

  3. Visual Analogical Scale (VAS) [ Time Frame: 7, 14, 21 and 28 days ]
    Symptoms evaluated using numeric Visual Analogical Scale (VAS): asthenia, headache, ageusia, anosmia, and rhinitis.

  4. All-cause mortality [ Time Frame: 7, 14, 21 and 28 days ]
    Mortality from any cause during the study

  5. Number of visits to primary care [ Time Frame: 28 days ]
    Number of visits of any kind to primary health care settings (phone visit or face to face visit) during the study period.

  6. Number of visits to the emergency room [ Time Frame: 28 days ]
    Number of visits to emergency room form primary health o hospital settings during the study period.

  7. Number of hospital admissions. [ Time Frame: 28 days ]
    Number of hospital admissions during the study period.

  8. Medication side effects [ Time Frame: 7, 14, 21 and 28 days ]
    Number and type of adverse reactions during the study period related to medication.

  9. Days of sick leave [ Time Frame: 28 days ]
