GC + hydroxychloroquine

GC + hydroxychloroquine is a combination therapy consisting of "GC" and hydroxychloroquine. Hydroxychloroquine is an antimalarial and immunomodulatory small molecule, widely used for the treatment of malaria, rheumatoid arthritis, and lupus erythematosus. It acts by interfering with lysosomal activity and autophagy in immune cells, as well as modulating antigen presentation and cytokine production. The identity of "GC" in this context is unclear; it may refer to glucocorticoids (a class of corticosteroids), but no specific drug named "GC" could be confirmed from available sources. Combination regimens involving hydroxychloroquine have been explored in various settings, including COVID-19 research[1][4][5].
