Studying the structure of molecular graphs of drugs, especially drugs effective in treating Covid-19, is practical and essential. Gourava indices have critical applications in chemistry; they have a high correlation with entropy and acentric factor. In this article, first, neighborhood Gourava indices are introduced. Then the mathematical relationship between NM-polynomial and neighborhood Gourava indices are obtained. Using NM-polynomial, neighborhood Gourava indices are computed for the molecular graphs of Dexamethasone, Chloroquine, Hydroxychloroquine, and Remedsivir.
