Testing New Medicines *suitable for home teaching*

A Catalyst article exploring the testing of new medicines to see if they are safe for people to take. The effects on cells of a potential new drug are investigated using tissue cultures of human or animal cells. Some tissue cultures use fresh tissue samples, but most come from well-established laboratory cell strains. If a substance harms abnormal cells, such as cultured cancer cells, or stops viruses infecting cells, it could be useful. At the same time, scientists check that the drug does not affect normal cells. The article looks at the processes involved, from laboratory tests to clinical trials.

This article is from Catalyst: GCSE Science Review 2006, Volume 17, Issue 1.
