Prescription of psychotropic drugs in paediatry: approved indications and therapeutic perspectives

In France, psychotropic drugs may be classified in four categories according to their official data. The first category corresponds to psychotropic drugs with an approved indication available in paediatry. Theyare old agents (e.g. haloperidol, amitriptyline, benzodiazepines...) with the exception of methylphenidate (hyperactivity). The second one corresponds to pharmacological agents approved for some indications obtained with adults but not for a1l (i.e. restricted indication: e.g. sertraline approved in paediatry only for OCD but not for depression, risperidone approved only for the treatment of disruptive behaviors in children with subaverage IQs). For the third category, the psychotropic agent is either contraindicated or unadvised under the age of 15 or 18 years, by lack of data (e.g. most of SSRI or atypical antipsychotic drugs). For the last category, official data available in brief summaries offer no information on paediatric use and consequently their administration does not appear possible. Up to now, no approved use has been delivered to injection route (IM or IV) in France, except for an IM formulation of zuclopenthixol. Prescribing psychotropic drug has to respect good practices including close psychological and somatic monitoring that associates the young patient and his relative (psycho-education program). Particular key-points should be taken into consideration (i.e. pharmacokinetic and physiological specificities, risk of false passage under the age of 6 years with capsules or tablets, presence of alcohol in some oral solution or bitter aroma...). Beside these official data, many studies have been published but must be carefully interpreted according to their level of pertinence. Meta-analysis gather all randomised controlled trials published or not, analyse their specific pertinence and thus provide clinically relevant elements. Randomised controlled trials present clinical interest but key-points in study design must be checked (e.g. number of patients, inclusion and exclusion criteria, length of the study and clinical relevance of clinical scales...). Other studies like open trials or clinical cases do not offersufficient guarantees. Some randomised controlled trials of clinical relevance have been carried out in this population with new pharmacological classes (eg SSRI, atypical antipsychotic drugs) and may lead to extended indications in children and adolescents. According to bibliographic and official data, the main criteria in the
