Kids’ medicine
‘danger’ shock

They are licensed , but only for adults.


To market a drug in the UK a
pharmaceutical company must
obtain a licence from the
licensing authority (health
ministers guided by the MHRA
or EMA)
The aim of a licence is to
ensure that all medicines in
the UK meet acceptable
standards of safety, quality
and efficacy
Extent of a product licence

market a drug for;
 specified conditions
 in an agreed dose
range
 by a particular route
 using a tested
formulation
Based on clinical trial
