Understanding Acalabrutinib: Benefits, Dosage, and Side Effects #
Acalabrutinib is a chemotherapy drug primarily used to treat certain types of lymphoma and blood cancers, such as mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL). This medication is an inhibitor of protein kinase, an enzyme that plays a crucial role in the growth and division of cancer cells. Acalabrutinib works by hindering this enzyme, thereby preventing cancer cells from growing and spreading, though it is important to note that the drug does not cure cancer outright.
Available in capsule form, Acalabrutinib needs to be taken consistently over the long term. As with all chemotherapy drugs, it is crucial to consult with a healthcare professional before beginning treatment with Acalabrutinib.
