Effects of Ivermectin-azithromycin-cholecalciferol combined therapy on COVID-19 infected patients: A proof of concept study

As the world faces COVID-19, the search for effective treatments against the disease and its complications has turned its gaze to drugs that are classically used in other infectious diseases. Some drugs are being examined for the recent evidence on its effects on viral replication and inflammation. The aim of the study was to assess the outcome of Ivermectin-Azithromycin-Cholecalciferol combination therapy on early stages (I-IIa) of COVID-19 patients. This proof of concept study was carried out on confirmed COVID-19 patients in Mexico City, from April 01 to April 20, 2020. Patients who met inclusion criteria were invited to take Ivermectin (6 mg once daily in day 0,1,7 and 8) plus Azithromycin (500 mg once daily for 4 days) plus Cholecalciferol (4000 UI twice daily for 30 days). Treatment outcome was evaluated on the 10th day onward from the first day of the drug intake. Recovery rate of the 28 patients that received the combination therapy was 100%, the mean symptomatic recovery duration was 3.6 days and negative PCR was confirmed on day 10. Imaging findings of patients with pneumonia were improved on day 10. Transient and mild degree of adverse effect like diarrhea and nausea was noted by 3 (10.7%) patients. This study found that the combination treatment might mitigate disease progression without significant adverse effects. Further studies are needed in order to extrapolate these findings to moderate and severe COVID-19.
