简要总结
This randomized controled open label clinical trial conducted in patients with hypoxemic respiratory failure admitted to the ICU and requiring ventilatory support (invasive or non-invasive) is to evaluate whether treatment with cyproheptadine, a serotonin receptor antagonist, compared to usual care, increases the number of ventilator-free days.
详细描述
Some studies have shown increased platelet activation and reactivity in patients with COVID-19. This platelet activation is associated with serotonin release. Some characteristics observed during the evolution of COVID-19 may be associated with these increased levels of serotonin. In this scenario, the antagonism of the action of serotonin could improve the clinical course of patients affected by COVID-19. Cyprohepatdine is an anti-serotonergic antihistamine drug with a long track record of safety and tolerability.
Investigators will randomize 274 patients who have tested positive for COVID-19 and who will be admitted to the ICU requiring ventilatory support (invasive or non-invasive).
Patients will be randomized to a 1:1 ratio for receiving usual care + cyproheptadine (8mg three times a day for 10 days) or usual care.
Patients will be followed until discharge to determine length of stay in the ICU and hospital, mortality in the ICU and hospital and days free from ventilatory support during the first 28 days.

研究组 & 干预措施
Cyproheptadine and usual care
Patients allocated to the intervention group will receive cyproheptadine within 6 hours after randomization, at a dose of 8mg every 8 hours for 10 days.
Usual care (diagnostic testing, antibiotic administration, fluid resuscitation, hemodynamic management, and ventilatory support) will be applied in accordance with the clinical practice of each institution.
干预措施: Cyproheptadine (Drug)
