(a) The drug is listed as "A" or "B" rated in the most recent version of the United States food and drug administration's approved drug products with therapeutic equivalence evaluations, also known as the orange book, or has an "NR" or "NA" rating or similar rating by a nationally recognized reference; and
(b) The drug is generally available for purchase by pharmacies in this state from a national or regional wholesaler and is not obsolete.
