What will work on COVID-19? This question has been on the world's medical and scientific brains for the past few months. A large number of drugs are being tested and evaluated on a trial basis on patients. But many of the medical fraternity feel that whether these drugs and therapies - Remdesivir, Favipiravir, Ivermectin, Doxycycline, Tocilizumab and plasma therapy etc - are working on patients, is debatable.

"We must understand that there are 35,000 medications in the text books. There will be no end to trial and error. People cannot grope in the dark, with change in line of treatment with every new claim made by some experts in the world, without randomised controlled placebo trials. The need of the hour is symptomatic and supportive treatment, like it is done for dengue, which doesn't have any treatment," explained Dr Wiqar Shaikh, senior asthma and allergy specialist.
