MONTPELIER, Vt. — Vermont Attorney General William Sorrell says he’s disappointed by the U.S. Supreme Court ruling that struck down a state law designed to protect patient privacy and reduce health care costs.

Sorrell says the challenge now will be to continue to work to protect medical privacy and reduce health care costs without violating the Supreme Court’s ruling. He calls it a step back, but not the end of the story.

The law would have forbid drug manufacturers from using information about the prescription drugs doctors prescribe to tailor their sales pitches to physicians.

In its 6-3 decision, the Supreme Court ruled Thursday that Vermont couldn’t “engage in content-based discrimination to advance its own side of a debate.”

The ruling imperils similar laws in New Hampshire and Maine.
