For these reasons, it has been restrict- ed in both adult and pediatric patients. Methadone restrictions were modified to address conflicts between the pediatric and adult criteria for use. The goal is to limit methadone use to prescribers who can safely The following revised methadone criteria were developed.

Pediatric patients in adult units will follow adult restrictions. Pediatric use for pain will be approved by a Hematolo- gy-Oncology progress note. Continuation of a home regimen for opioid addiction is allowed. For patients greater than 18 years of age, methadone will not be included in any order set. Continuation of a home regimen for the treatment of opioid addiction continues to be acceptable. Continuation of a home regimen for chronic or cancer pain is allowed. The pre- hospitalization dosage must be verified, and the dose cannot be modified.

distribution drugs
I n last month’s Bulletin, various formulary
viewed. The term restricted drug distribution program was used, and some readers of the Bulletin were not familiar with this term. Restricted drug distribution programs [or systems] are methods used by drug compa-nies to limit access to drugs, primarily for safety reasons.1-5 These agents are some-times called “limited distribution drugs.” The restrictions or limitations fall under the FDA’s Risk Evaluation and Mitigation Strategies (REMS). Restricting drug access has a long history, and this article briefly explains these heterogeneous programs. When these programs were last reviewed in the Bulletin in 2003, the legal authority to restrict access to FDA approved drugs was questionable.3 In 2007, legal authority was given by the FDA Amendments Act (FDAAA) by establishing REMS, which allows for “re-strictions on distribution.” Prior to 2007, a small number of drugs that offered substantial therapeutic benefits, but significantly increased risks relative to most drugs in that therapeutic area were available only by restriction distribution.3 Clozapine was an early example of this. Clozapine is still the gold standard for treat-ment-resistant schizophrenia. In early clinical trials, it was estimated that approximately 1% of patients treated with clozapine developed agran-ulocytosis. Drugs usually never make the market when 1 in 100 patients are at risk of dying. Yet, in treatment-resistant patients who have white blood cells (WBCs) monitored closely, it can be used safely and provide relief for patients who do not respond to less risky options. Clozapine was only dispensed in small amounts after the patient provided a blood sample that showed that they were tolerat-ing therapy. This “blood for drug” program prevented patients from from a fatal adverse effect, while treating their condition. If clozap-ine was stopped before WBCs dropped too far, the adverse effect was reversible. Many restricted drug distribution systems are administered by specialty pharmacies like Accredo, Caremark, or CuraScript. These pharmacies limit their activities to high cost/low volume drugs that are often “high profit” and/or “high risk.” Low patient volumes allow more time to monitor the restrictions placed on the drugs before they are delivered to patients. Not all restricted drug distribution pro-grams are limited to specific pharmacies. For example, any pharmacy willing to abide by the clozapine restrictions can dispense this drug. The safety checks might require special laboratory testing (eg, pregnancy testing for a Category X teratogen) or diagnostic criteria. Shands at the University of Florida
