Payments from drug & device makers
What this record shows
This record is dominated by food and beverage: $5,186 of the $7,811 with a category attached, or 66.4%. 20 manufacturers reported payments, led by Ironwood Pharmaceuticals, Inc at 33.6% of the total. Reporting peaked in 2022 at $4,302 and has fallen 89.8% since, to $437 in 2024. Among medical clinicians in TX with any reported payments, this total sits in the top 10% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 142 payments — averaging $55.01 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.
