The Oregon Division of Financial Regulation released a list of the top 25 most-expensive prescription drugs in Oregon this week. These are the drugs that “contribute the most to annual spending by health insurance companies.”

According to insurance commissioner Andrew Stolfi, this and other lists released by the division "highlight the goal of the drug price transparency program."

“They provide a first step to transparency for Oregonians,” he added, “and help all of us better understand which prescription drugs affect health care costs.”

To determine what drugs are most costly, the division considered the drug’s retail cost as well as rebates and “other price concessions.”

“The most costly drugs are the prescriptions that are the most expensive for insurance companies based on annual health plan spending,” Brad Hilliard, a spokesperson for the Oregon Division of Financial Regulation, said over email. “This includes the net effect of any rebates and other price concessions.”

While drug prices aren’t listed by the state, the website

provides information on prices at different pharmacies. For drugs that are administered by a doctor and therefore not available at a pharmacy, we found price information on the website

.

You may note that some of the prices don’t fall in line with the state’s list. That’s because the state’s list is based on cost to insurance plans.

Also, drugs are sold in different dosages that last patients different lengths of time. So one price may be for a full year of the drug while another could be for just one month.

Here are the top 25 most-expensive prescription drugs in Oregon and how much they cost.
