Comparison of levels of different sustained-release drugs and non-sustained-release methylphenidate.

There are a number of drug treatments for ADHD in 2021 Medication available with different active ingredients and mechanisms of action. So-called psychostimulants, which have a dopaminergic effect, are considered to be the most effective and best studied. The most frequently prescribed generic drugs in Germany are methylphenidate (MPH), Lisdexamfetamine and the non-stimulant atomoxetine. In addition to these substances, there are a number of other drugs that can be used to treat ADHD, although they are not approved for the treatment of ADHD (off-label use). Sometimes these drugs are also used to treat comorbidities, for example to treat depression, and can then also have effects on the ADHD symptoms.[1]

Detailed information on ADHD drug treatment can be found in the Pharmacotherapy article.
