Definition: Benzalazine is a drug used to treat certain types of cancer, such as leukaemia and multiple myeloma. It works by inhibiting the activity of a protein called caspase 3, which plays a key role in cell death. The drug is derived from benzyl alcohol and is administered intravenously or by injection. It can be prescribed for various types of cancer, but its use should be carefully monitored due to its potential side effects and interactions with other medications.
