Balanced approach preferred.

None.
Search terms / synonyms / search strategy
Will search under dexamfetamine at BNF chemical level and review formulations beneath that.
Inclusion criteria for codes
Is a formulation licenced to treat ADHD, and expectation is that it would primarily be prescribed for ADHD.
Exclusion criteria for codes
Is a formulation not licenced to treat ADHD, or expectation is that it would primarily be not be prescribed for ADHD.
Borderline cases
Some formulations, e.g. 'dexamfetamine sulfate 5 mg tablets' are licenced for both ADHD and nacrolepsy. However, given the relative rarity of nacrolepsy in children, the impact of including these formulations on search specificity is likely acceptable.
