Background:

The first case of Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were diagnosed in Wuhan, China in 2019. In the first half of 2020 this disease has already converted into a global pandemic. Objectives: To assess the efficacy of Ivermectin in mild cases of COVID-19 patients on the basis of predefined assessment criteria. Study Settings: Fatima Memorial Hospital, Lahore Study Design: Open label randomized control trial. Duration of Study: From 1st May, 2020 to 30th June, 2020.Patients & Methods: Sample size and technique: Sample size was 50 patients; 25 patients were kept in control group and 25 patients were kept in experimental group

The first case of Infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were diagnosed in Wuhan, China in 2019. In the first half of 2020 this disease has already converted into a global pandemic, having different forms of presentation in different patients.

Exponential rise in its cases along with associated mortality has shaken the world.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a single-stranded ribonucleic acid (RNA) virus that causes a severe acute respiratory syndrome. The virus was originally called SARS-CoV-2 named officially by World Health Organization as COVID-19 and a global health emergency. The first known case of infection was recorded in early December 2019 and subsequently spread to various continents, including Europe and the United States.Generally, 75 percent of patients recover without any notable complication however 25 percent can experience associated complications leading to intensive care unit transfer and even mortality.

Ivermectin has different effects to treat variety of diseases and it has proven antimicrobial, antiviral, and anti-cancer properties and considered as a wonder drug. It is highly effective against many microorganisms including some viruses. Many studies revealed its antiviral effects on RNA viruses such as Zika, dengue, yellow fever, West Nile, Hendra, Newcastle, Venezuelan equine encephalitis, chikungunya, Semliki Forest, Sindbis, Avian influenza A, Porcine Reproductive and Respiratory Syndrome, Human immunodeficiency virus(HIV) type 1, and severe acute respiratory syndrome coronavirus SARS-CoV-2. Fon other hand there are few studies showing antiviral effects of ivermectin against DNA viruses such as Equine herpes type 1, BK polyomavirus, pseudorabies, porcine circovirus 2, and bovine herpesvirus 1.5 Ivermectin plays a vital role in several biological mechanisms, therefore it could emerge as a potential candidate in the treatment of a wide range of viruses including COVID-19 as well as other types of positive-sense single-stranded RNA viruses. In vivo studies of animal models revealed a broad range of antiviral effects of ivermectin, however, more clinical trials are necessary as it's the need of the hour to do so, as we can validate the potential efficacy of ivermectin in clinical settings.

The recent report by Caly et al.6 describing the antiviral potential of ivermectin against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in vitro arrive to the agenda of potential candidates for COVID-19 treatment.

Currently, there is not any Food and drug administration (FDA) approved specific effective antiviral treatment available for COVID-19.Although most of the COVID-19 patients have mild or moderate courses, up to 5%-10% can have severe, potentially life threatening course, there is an urgent need for development of effective & safe drugs to deal with this novel virus. Optimized supportive care remains the mainstay of therapy. There are more than 300 clinical trials going on, various antiviral and immunomodulating agents are in different stages of evaluation for COVID-19 in those trials and results/ primary end points of few trials will be published in the next couple of months. Despite the urgent need to find an effective and safe antiviral treatment for COVID-19 through randomized controlled studies, certain agents are being used all over the world based on either in-vitro or conclusive evidence or observational studies.

The clinical efficacy and utility of ivermectin in SARS-CoV-2-infected patients is unpredictable at this stage, as we are dealing with a completely novel virus.

There is an urgent need for investigation of the mortality causes and development of novel therapeutic options for severe COVID-19.
