Payments from drug & device makers
What this record shows
The money is spread across several categories — speaking fees (43.3%), consulting fees and travel and lodging — rather than concentrated in one kind of arrangement. Acadia Pharmaceuticals Inc accounts for 64.7% of it on its own, with 17 other manufacturers making up the rest. 2025 is the largest year on record at $19,651, more than ten times the $171 reported in 2021. Among pediatrics clinicians in AZ with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 169 payments — averaging $140.83 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
