Examples

Busulfan is available as a pill you can swallow. It is also available in an IV form, used for stem cell transplants.

How It Works

Busulfan is classified as an alkylating agent. It kills cells by interfering with the way they multiply.

How Well It Works

Busulfan may be effective in slowly destroying blood cells in people who cannot take other drugs for their CML.¹
