I've been to two psychiatrists and they both suggests similar meds for focus/concentration/attention/impulsivity:

Stimulants: Vyvanse / Concerta / Adderall

Non-Stimulants: Intuniv / Kapvay / Strattera /Aplenzin

Mood Stabilizer(?): Wellbutrin / Efexxor / Elavil / Lamictal

I haven't tried them yet. Let me know if you had any luck with those listed above.
