Aprepitant as a combinant with Dexamethasone reduces the inflammation via Neurokinin 1 Receptor Antagonism in severe to critical Covid-19 patients and potentiates respiratory recovery: A novel therapeutic approach
AbstractCorona virus infection is a respiratory infection, compromising the normal breathing in critical patients by damaging the lungs. The aim of this study was to evaluate the clinical outcomes of Substance P receptor Neurokinin 1 antagonist in Covid-19 patients against the usual treatments as controls.MethodsIt is a randomized clinical trial, open label, having two arms, one receiving normal management and care while other receiving Neurokinin-1 Receptor antagonist, Aprepitant, in addition. Dexamethasone, a corticosteroid is also administered orally to both the groups. PCR positive, hospitalized patients with more than 18 years of age, both genders, moderate to critical phase were included. 41 patients were randomly allocated in both arms, having 21 patients in group A and 20 patients in group B. Lab investigations were performed in both the groups before and after the intervention.ResultsMean age of patients in group A was 50 ±18 years while 55±11 years in group B. There were 14/21 males in group A and 15/20 in group B. There were 3 critical patients in group A and 5 in group B. Biochemical and hematological parameters in both groups didn’t show much difference except the C-reactive protein reduction in the intervention group, indicative of a reduced inflammation.ConclusionsThe findings of this current study give a strong clue for the therapeutic potential of Aprepitant. Patients who received a combination therapy of Aprepitant and Dexamethasone showed improved clinical outcomes, laboratory findings and reduced C-reactive protein which is an inflammatory marker.Trial RegistrationThis trial is registered inclinicaltrials.gov(NCT04468646).
