## Common cost drivers for Hydrochlorothiazide

- **PBM rebate opacity:** Pharmacy benefit managers (PBMs) negotiate rebates with manufacturers that aren't passed to patients. Cash-pay prices can be LOWER than insurance copays for the same drug.
- **Patent/exclusivity status:** Brand exclusivity on Microzide keeps the price elevated until generics enter the market.
- **Drug class market dynamics:** Thiazide Diuretics pricing is influenced by class-wide demand and competing therapies.
- **Pharmacy markup:** Retail pharmacies mark up acquisition cost 3-10x to cover overhead and PBM clawbacks. Independent and compounding pharmacies bidding on Script Unlock skip the PBM layer entirely.
