Kids’ medicine
‘danger’ shock
SOME children’s medicines have not been approved for
consumption by youngsters according to a report
published yesterday.
It warns that most medicines either prescribed or sold direct
are safe but a minority could do harm in the wrong doses.
They are licensed , but only for adults.

The licensing process


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
It allows a company to
market a drug for;
 specified conditions
 in an agreed dose
range
 by a particular route
 using a tested
formulation
Based on clinical trial
data
EMA / MHRA Product Licence

Paediatric Investigation Plan (PIP)
• Paediatric Regulation to submit a
development plan for new medicines
• Specific class waivers

Paediatric-Use Marketing
Authorisation (PUMA)
• Already authorise medicine
• 10 years market protection
Paediatric clinical trials
“By an odd and unfortunate twist of fate, infants and children are
becoming therapeutic orphans”
Shirkey H 1968
Lack of Clinical trials





80% of new drugs had no
info in paeds
WHY ?
ethics
long term effects
micro-analytical techniques
return for investment
Directive
89/341/EEC
all doctors can prescribe:



there is no statutory requirement to

unlicensed
all unlicensed prescribing /

body of professional opinion
