(1) The board shall prepare by regulation a nonequivalent drug product formulary of drugs with their generic names for which there are no equivalent drug products, and which should not be interchanged by pharmacists. The nonequivalent drug product formulary shall list all drugs, drug products, and dosage formulations that the United States Food and Drug Administration has determined to be therapeutically nonequivalent.
(2) The board shall provide for annual distribution of copies of such formulary and revisions and additions thereto among pharmacies licensed within the Commonwealth and shall supply a copy to any person on request upon payment of the price established by the board. Such formulary shall be revised and distributed as often as new and pertinent information on drugs, drug products, and dosage formulations becomes available from the United States Food and Drug Administration.
