(Salem, OR) -- Oregon state lawmakers are pondering legislation that supporters say is aimed at reducing prescription drug prices. The "Portland Tribune" reports the bill would cap patients' out-of-pocket copayment for prescriptions, require pharmaceutical companies to explain steep increases in the cost of a medication, and mandate rebates when prices exceed a certain level. Another measure would also require drug companies to include the average wholesale price of a medication in any type of direct consumer advertising. Public hearings on the legislation will be held in the coming weeks.
