we will evaluate the impact of addition of tablet Pentoxifylline to conventional treatment in patients with moderate COVID -19 disease on reduction in need for invasive ventilation (IV) i.e. intubation and mechanical ventilation. <br/ >Lesser number of patients with moderate COVID disease on WHO ordinal scale 4 ( i.e those who require oxygen therapy through face mask/ nasal prongs) would deteriorate to WHO Ordinal scale 6 (i.e. those needing intubation and mechanical ventilation)Timepoint: 28 days
