This clinical trial is focused on studying treatments for COVID-19 in patients who are at a higher risk of experiencing severe illness. The trial will explore the effectiveness of different treatments provided in primary care settings. One of the treatments being studied is a medication called Montelukast, which is taken as a film-coated tablet. This medication is commonly used to manage asthma and allergies by reducing inflammation in the airways.
The purpose of the study is to determine how well these treatments help patients recover from COVID-19. Participants in the study will be randomly assigned to receive either the treatment or usual care, which may include a placebo. The study will track the time it takes for participants to feel fully recovered from their symptoms, as well as other health outcomes such as hospital visits and overall well-being.
Throughout the study, participants will be asked to keep a daily diary to record their recovery progress. This will help researchers understand how the treatments impact recovery time and overall health. The trial aims to create a framework for future studies in primary care settings, not only for COVID-19 but also for other emerging diseases.
