Antipsychotic Utilization: Oregon State Medicaid Ann M. Hamer, PharmD BCPP This presentation was made possible by a grant from the State Attorney General Consumer and Prescriber Education Program which is funded by the multi-state settlement of consumer fraud claims regarding the marketing of the prescription drug Neurontin

Background In 2004, Warner-Lambert (now a division of Pfizer, Inc.) paid $430 million to settle claims that it was using continuing education grants to promote off-label uses of Neurontin.

Background The 50 state attorneys general who accepted the settlement of the Neurontin case have used $21 million to establish the Consumer and Prescriber Grant Program, designed to provide healthcare professionals and consumers information related to prescription drugs and their marketing.

Objectives Develop critical skills to promote an evidence-based approach to the medical literature; Create awareness of the persuasive marketing practices of the pharmaceutical industry; Assess the impact that pharmaceutical costs can have on other healthcare priorities; Balance the ethical responsibility to the patient vs. the ethical needs of society in prescribing practices; and Develop skepticism about off-label indications for a drug without compelling evidence-based research that supports such use.

Methods Academic Detailing Focused on the utilization of behavioral health medications Didactic Lectures Focused on the evaluation of medical literature and pharmaceutical marketing Web-Based Tutorials Focused on the evaluation of medical literature and pharmaceutical marketing

Topic Selection Antipsychotics After specialty pharmaceuticals, antipsychotics are the most expensive drug class for the Oregon Health Plan Costing approximately $3.2 million each quarter Drug class where small changes can have a big impact on overall cost Provides a good example of some off-label use

Seroquel 69% of patients on therapy for 90 or more days were on low dose (<300mg/day). Total n=24 31% of patients on therapy for 90 or more days were on therapeutic dose ( mg/day) Total n=6 No patients were on duplicate antipsychotic therapy with Seroquel for 90 or more days. Roughly 50% of patients started on Seroquel maintain treatment for 90 or more days.

Low Dose Seroquel The use of Seroquel as a sedative has not been studied and efficacy and safety are questionable. Adverse effects = anticholinergic side effects, hypotension, hyperprolactinemia, metabolic abnormalities, agitation and akathisia.

Low Dose Seroquel Cases of Seroquel misuse and abuse have been reported in the medical literature. Street name = “quell” and “Susie-Q”
