The Drugs Work- and for More than One Purpose
Most drugs have a number of effects. Usually there is one purpose for which a drug licence is obtained, for example, aspirin as a painkiller. But often a drug can have another practical use: low-dose aspirin can be used for stroke prevention, for example. Prof Patrick Murray, Dean, School of Medicine and Prof of Clinical Pharmacology, UCD said
If it makes sense that a drug for one condition also has another effect on the body, doctors may prescribe “off-label” for purposes other than those covered by the drug licence. Sometimes enough evidence is gathered over time that a drug is safe and effective in this second disorder and it is repurposed gaining a licence for this second use.
