Vitroâ€ is derived from the Latin referring to glass. Thus in vitro means occurring in laboratory apparatus, such as a test tube. When a medication is effective in vitro it means it has been shown in a laboratory to have an action in an artificial or â€œglassâ€ environment â€“ a test tube, for example. Usually the first stage of testing a new medication is in vitro research.
