What health systems spend on each medicine
The cost of every medicine dispensed in the community in England, and every drug reimbursed by US Medicaid, from the two systems' own published data.
NHS England spent £11.89bn on medicines and appliances dispensed in the community from Aug 2025 to Jul 2026, +6.6% on the previous 12 months, at list price before discounts. Tirzepatide cost the most, at £795.3m, and the ten costliest items took 22.6% of the total. US Medicaid paid $111.94bn for outpatient drugs in 2025 before manufacturer rebates, led by semaglutide (Ozempic, Wegovy, Rybelsus) at $6.50bn. Both figures are gross: neither system publishes the discounts and rebates it receives per drug.
Showing medicines matching “Omeprazole”: 2 in England, 5 in Medicaid (first 100 of each).
NHS England: cost by medicine
Aug 2025 to Jul 2026, net ingredient cost| # | Medicine (BNF chemical substance) | Cost, 12 months | Change | Items | Cost per item |
|---|---|---|---|---|---|
| Omeprazole Gastro-Intestinal System |
£98.5m | -2.8% | 35,214,426 | £2.80 | |
| Esomeprazole Gastro-Intestinal System |
£14.7m | +16.9% | 2,922,865 | £5.02 |
Net ingredient cost is the list price of what was dispensed, before discounts, fees and patient charges. It covers prescriptions dispensed in the community in England, including appliances such as glucose sensors and catheters, not hospital medicines. Where the BNF moved products to a new code during the year, no change is shown because the two periods count different products. Cost per item is calculated here.
US Medicaid: spending by drug

The amount Medicaid reimbursed pharmacies for outpatient drugs, national totals from all states, before the manufacturer rebates Medicaid receives (CMS does not publish rebates per drug). Rows CMS suppresses because they cover fewer than 11 prescriptions are left out. Products are grouped by active ingredient using the FDA NDC Directory, which named 99.4% of the spending; the rest keeps CMS's short product name and is only in the product totals. Cost per prescription is calculated here.
