Pharmacology
Rasburicase is a recombinant urate-oxidase that catalyzes enzymatic oxidation of poorly soluble uric acid into allantoin, a more soluble inactive metabolite, rapidly reducing plasma uric acid levels within 4 hours of administration.
Ibrutinib is a small-molecule BTK inhibitor that forms a covalent bond with a cysteine residue in the BTK active site, inhibiting BTK enzymatic activity and blocking B-cell antigen receptor and cytokine receptor signaling pathways necessary for B-cell trafficking, chemotaxis, and adhesion.
