Ohio Region Drug Therapy ADVISORY Crestor to Atorvastatin Conversion (Paul Bandfield, PharmD, Formulary Management Services) All strengths of atorvastatin (10, 20, 40 and 80mg) have recently been added to the Commercial formulary Atorvastatin is on the generic tier for members with a Commercial HMO benefit and tier 2 nonpreferred generic for members with a Medicare Part D benefit All strengths of rosuvastatin (Crestor) are non-formulary for Commercial HMO members and tier 4 nonpreferred brand for members with a Medicare Part D benefit Since atorvastatin is available at a generic copay, members converted from Crestor to atorvastatin will save an average of $200 annually depending on an individual member’s copay structure Atorvastatin is indicated for primary and secondary prevention of cardiovascular events Atorvastatin is metabolized by the cytochrome P450 3A4 enzyme (CYP3A4) and has many of the same interactions as simvastatin and lovastatin o Unlike simvastatin, atorvastatin is not currently listed as having a clinically significant interaction with amlodipine o Although interactions have been documented between atorvastatin with amiodarone, diltiazem or verapamil, no maximum interacting doses of atorvastatin have been advised by the Food and Drug Administration (FDA) Crestor undergoes minimal hepatic metabolism (about 10%), primarily via CYP2C9 enzyme; there is essentially no metabolism via CYP3A4, indicating a low propensity for interactions compared to other statins Approximately 25 patients can be treated with atorvastatin 80mg for the same cost as treating one patient with Crestor 40mg or 20mg Table 1 provides equipotent doses for Crestor and atorvastatin Table 1: Daily Dose Providing Similar LDL-Lowering 20mg (47%-55%) 5mg 10mg (46-52%) (45%) 20 mg (47%-55%) 40 mg (55%-63%) 20mg Atorvastatin 40 mg (50%) 80 mg (55%-60%) (43%) Conversions Earlier in 2012, a therapeutic interchange from Vytorin 10/80mg and 10/40mg to atorvastatin 80mg was approved by the Ohio Pharmacy and Therapeutics Committee The Crestor to atorvastatin initiative is a conversion and not a therapeutic interchange Ohio Kaiser Permanente pharmacists will contact OPMG and Network prescribers for conversion of each qualifying patient individually o Members with a documented allergy to atorvastatin or who are taking medications with clinically significant interactions to atorvastatin will not be converted o Each converted member will receive a letter explaining the conversion Crestor Issue 7 July 2012 Network Edition Conversions will be conducted according to the following: Crestor Dose Consider Conversion to Crestor 40mg → Atorvastatin 80mg Crestor 20mg → Atorvastatin 80mg or 40mg Crestor 10mg → Atorvastatin 40mg Crestor 5mg → Atorvastatin 20mg Affordable Care Act: $0 Contraceptive Benefit (Alynn Anzevino, PharmD, Manager, Formulary Management Services and Pharmacy Benefits) • The Affordable Care Act requires insurance plans to provide access to prescription contraception with zero dollar patient cost share • KP will offer a $0 contraceptive copay for formulary products for Commercial plans effective after August 1, 2012 and when the plan renews o For example, if a plan renews on November 2, the member would pay their current copays for contraceptives between August 1 and November 1 and would pay $0 copay after November 1 • If HMO member receives a formulary exception for a nonformulary contraceptive, it will be covered at $0 copay • The zero patient cost share does not apply to Commercial plans exempt from covering contraceptives Potential Administration Errors with Rotarix (Paul Bandfield, PharmD, Formulary Management Services) In 2006, RotaTEQ, the first rotavirus vaccine, was approved by the FDA RotaRIX became available in 2008 and is the preferred product at KP facilities since it is a two-dose regimen Since these two products both contain rotavirus and have similar names, there is a significant potential for confusion and mix-ups Both RotaRIX and RotaTEQ are oral vaccines and should never be given intramuscularly RotaRIX is supplied as a 2-dose regimen for infants o Usually given at the 2-month (age 6 weeks+) and 4-month well child visits o A 4-week interval is required between the first and second doses o Manufacturer-supplied diluent in a prefilled oral applicator is used to reconstitute the vial of lyophilized vaccine with the supplied vial adaptor o The final oral dose is 1mL; Refer to the vaccine’s approved labeling for reconstitution instructions (Continues on reverse side) Issue 7 — Network Edition (Continued from reverse side) RotaTEQ is supplied as a squeeze packet designed for dispensing the oral dose to the patient o RotaTEQ is given in 3 doses to infants at the 2, 4, and 6 month well child visits o Patients who started dosing with RotaTEQ should complete the series with the same product Recommendations Always store complete packages of RotaRIX and do not separate the contents Be aware of “spare” parts (e.g., syringes, adaptors, vials) that may be in stock supply areas, as this could be an indicator that the vaccine is being reconstituted or administered incorrectly Safety Update: QT Prolongation With Ondansetron Use (Andrea Nixon, PharmD, Formulary Management Services) FDA informed healthcare professionals that preliminary results from a clinical study suggests ondansetron (Zofran) may prolong the QT interval in a dose-dependent manner, which could predispose patients to develop an abnormal and potentially fatal heart rhythm, torsades de pointes GlaxoSmithKline announced changes to ondansetron drug label to remove the 32mg single intravenous dose Updated label states intravenous ondansetron can be used in adults and children with chemotherapy-induced nausea and vomiting at 0.15mg/kg up to a maximum of 16mg per dose, administered every 4 hours for three doses No single intravenous ondansetron dose should exceed 16mg New information on QT prolongation does not change any of the recommended oral dose regimens for ondansetron including the single oral dose of 24mg for chemotherapy induced nausea and vomiting or the recommended lower intravenous ondansetron dose to prevent post-operative nausea and vomiting Electrolyte abnormalities should be corrected prior to the infusion of ondansetron More information can be found at: http://www.fda.gov/Drugs/DrugSafety/ucm310190.htm FDA Alerts Hospira Injectable Drug Products: Recall - Visible Particulates from Defective Glass Vials http://www.fda.gov/Safety/MedWatch/SafetyInformation/SafetyAler tsforHumanMedicalProducts/ucm312048.htm Leucovorin Calcium Injection (Bedford Laboratories): Recall Visible Particulate Matter http://www.fda.gov/Safety/MedWatch/SafetyInformation/SafetyAler tsforHumanMedicalProducts/ucm310782.htm Vecuronium Bromide For Injection Preservative Free (Bedford Laboratories): Recall - Particulate Matter http://www.fda.gov/Safety/MedWatch/SafetyInformation/SafetyAler tsforHumanMedicalProducts/ucm310210.htm Initiatives Inter-Regional Clinical Pharmacy Services Subcommittee (ICPSS) Initiatives Dulera preferred over Advair and Symbicort OxyContin use discouraged over other long-acting opioids Atorvastatin preferred over Vytorin and Crestor Skeletal muscle relaxant use discouraged in elderly Hydroxyzine use discouraged in elderly Pharmacy Conversion Team Projects Half-Tab Initiatives ProAir day supply review Sumatriptan day supply review July 2012 Current Half-Tab Initiatives Abilify Crestor Levitra Nuvigil Viagra Aricept Imitrex Lexapro* Paxil Zocor Celexa Lamictal Lipitor Provigil Zoloft *Both brand and generic tablet products are half-tab initiatives Formulary Changes The Ohio Regional Pharmacy & Therapeutics Committee approved the following formulary changes.
