Etiology

Page 13: Ritalin ® & AD/HD just calming the troublemaker ??? Dr.med.Sven Schellberg Global Communications & Brand Manager Psychiatry NOVARTIS Pharma AG, Basel,

Etiology

• Attention, evaluation of situations, learning and activity are functions which are located in dopaminergic areas of the brain

• In animal experiments a depression of dopaminergic function leds to hyperactivity, aggression and worsening of learning procedures

AD/HD

Diagnosis

Page 20: Ritalin ® & AD/HD just calming the troublemaker ??? Dr.med.Sven Schellberg Global Communications & Brand Manager Psychiatry NOVARTIS Pharma AG, Basel,

There is no single diagnostic test for AD/HD

Page 21: Ritalin ® & AD/HD just calming the troublemaker ??? Dr.med.Sven Schellberg Global Communications & Brand Manager Psychiatry NOVARTIS Pharma AG, Basel,

Diagnosis

• History and anamnesis including interviews with patient, parents, teachers

• Symptomatology (differing criterias between DSM IV (AAP) and ICD-10)

• Rating Scales (CRS, CBCL etc.)

• Exclusion of other medical disorders (e.g. epilepsy, brain damage, schizophrenia, hyperthyreosis)

• physical examination including EEG, lab, intelligence testing

AD/HD

Treatment

Page 23: Ritalin ® & AD/HD just calming the troublemaker ??? Dr.med.Sven Schellberg Global Communications & Brand Manager Psychiatry NOVARTIS Pharma AG, Basel,

Treatment of AD/HD always has to combine educational, psychotherapeutical and

psychopharmacological methods

Page 24: Ritalin ® & AD/HD just calming the troublemaker ??? Dr.med.Sven Schellberg Global Communications & Brand Manager Psychiatry NOVARTIS Pharma AG, Basel,

Stimulants

• The use of stimulants started in the 1930‘s when their stimulative effects on the dopamingergic system and their psychotropic effects were discovered

• First Amphetamine and Metamphetamine were used

• First descriptions of an use of Methylphenidate in „MCD“ in the 1960‘s

• Detailed descriptions in the 1980‘s by Wender et al.

Methylphenidat IR vs. SR

Page 32: Ritalin ® & AD/HD just calming the troublemaker ??? Dr.med.Sven Schellberg Global Communications & Brand Manager Psychiatry NOVARTIS Pharma AG, Basel,

Facts and Problems

• Onset of action after 20 – 40 minutes• Duration of action 2-4 hours• Repeated dosing – often over school-time - mandatory• Acute tolerance requires peaked doses with raising

plasma levels over the day and drug free interval at night• Stable plasma levels show poor clinical efficacy, sharp

increase in plasma levels in the morning required

Page 33: Ritalin ® & AD/HD just calming the troublemaker ??? Dr.med.Sven Schellberg Global Communications & Brand Manager Psychiatry NOVARTIS Pharma AG, Basel,

Ritalin® LA - Objectives

• Fast onset of action in the morning, with a high morning dose

• Double peak pharmacokinetic with raising plasma levels over the day

• Duration of action about 8 – 10 h to cover schoolday, but not to interfer with sleep at night

• Easy to swallow, no food interaction• Easy switch from standard medication• Individualized dosing
