How Captabine works
Captabine is an anticancer medication. Inside the body, this medicine gets converted into 5-fluorouracil (chemical). This chemical hampers the synthesis of genetic materials (RNA and DNA) in the cancer cells, thereby interferes with their growth. This slows down the growth of cancer cells and eventually kills them.
