“We are in the process of drafting a request for proposal for pharmacy service,’’ says Wendi Norris, of the Miami-Dade Internal Services Department, which manages county buildings and leases. “They are not in default of the contract, but we are looking for a space that can operate in its entirety.’’

The war against prescription drug abuse continues in Florida. After a three-year investigation, federal authorities dismantled four of the nation’s largest pain clinics in August along with two pharmacies and one pharmaceutical supplier. Thirty-two people from across South Florida were indicted. Over the years, the enterprise doled out 20 million pills and profited $40 million from illegal sales of controlled substances. In July, federal authorities arrested a family of five charged as part of a drug and money laundering enterprise based at a Plantation pharmacy. From April, 2009 to May, 2010, the pharmacy ordered 1,038,560 tablets of oxycodone, more than 28 times the national average for dispensing pharmacies, according to federal documents. The profits: nearly $2 million.

Last month, CVS — with more than 700 stores in the state — notified a small number of Florida physicians that it will no longer fill their prescriptions written for Schedule II narcotics, including oxycodone, a measure to “prevent drug abuse and keep controlled substances out of the wrong hands,’’ according to a statement.

CVS spokesman Michael DeAngelis said in an email that letters were sent in late November.

“CVS Pharmacy Inc. has become increasingly concerned with escalating reports of prescription drug abuse in Florida, especially oxycodone abuse,’’ the letter read. “CVS will continue to review information, and will alert you if CVS pharmacy stores may fill these Schedule II narcotic controlled substance prescriptions in the future.’’
