TRENTON On Thursday, June 1, New Jerseyans moved closer to being able to search the Internet for the best prescription drug prices. The Assembly Budget Committee released a bill that would create a state Web site listing pharmacy-by-pharmacy retail prices for the 150 most frequently prescribed drugs. The Web site would be designed to easily allow consumers to find the cheapest prescription drugs and is aimed to decrease prices through enhanced competition. Gov. Jon S. Corzine has vowed to sign the bill, which has also advanced in Senate committees. New Jersey would follow New York, Maryland, Illinois and Florida in creating such a Web site. Under the bill, pharmacies would have to report retail prices weekly to the state to update the registry. Consumers would log into the site to search drug prices by ZIP code. The registry would be made available in writing to consumers who call a toll-free telephone number.
