Weathering the Storm

 


All of us at UniCare want to thank you for your understanding and cooperation during Hurricane Ivan last week and the aftermath.  We hope that all is well at your nursing home now.  It took all of us working together as a team to make sure your residents received their medication when they needed it and we truly appreciate your part.

 

Speaking of storms. . . Medicaid has one that we’ll all have to weather regarding the latest additions to the PDLs beginning in October.

 

Roy Pickering, RPh, whose statement “Hang on; it’s going to be a bumpy ride,” is not referring to a storm but to the following additions to the Medicaid Preferred Drug List:

*Older insulins (Humulin/Novolin N, R, 70/30,etc.) will be preferred over newer ones (Humalog/Novolog), Lantus.

*Exelon will be preferred over Aricept and Reminyl.

*Doing without will be preferred over Namenda.

*Glyburide/Glipizide will be preferred over Amaryl.

 

 

*Starlix is preferred over Prandin.

*Glyset preferred over Precose

*Avandia is preferred over Actos.

*Omeprazole, Prevacid and Protonix will be preferred over Aciphex and Nexium.

 

The October PDL also addresses certain topical agents, including steroids and antifungals.  It’s mostly a story of generics preferred over brands.  Santyl is nonpreffered; Accuzyme and Xenaderm are acceptable.  Generic Bactroban (regular ointment only, at present) is preferred over the branded cream.  Bactroban Nasal is nonpreferred.

Medicaid PDLs and Your Facility

 


If you haven’t already, your facility should soon receive a letter explaining the insulin products with a list of residents currently receiving them.   All other categories will be handled with a PAL (Physician Approval Letter) which we will generate and send to the doctors.  The insulin is too individualized to handle this way.

UniCare has been way ahead of the PDL issue since its beginning.  We have worked behind the scenes on Prior Authorizations and getting approval to make changes to CAID covered drugs from your doctors.  We have internal staff assigned to this process which involves tons of paperwork and phone calls to either get the medication

 

changed or the criteria submitted to Medicaid for Prior Approval of a non-covered drug. 

Annual Survey Information Requested

 

As your time permits, please e-mail Sallie Reynolds the date of your last annual survey.  Her address is sallie.reynolds
@omnicare.com.  We need to update our records so we can better assist you.  The month is fine; we don’t need the actual day.  Thank you in advance.

 

 

 

NEW DRUGS/FORMULARY INFO

First OTC Cholesterol Drug Launched in Britain

Britain became the first country in the world to sell a cholesterol-lowering drug without a prescription on Thursday when a low-dose "over-the-counter" (OTC) form of Merck & Co Inc's Zocor was launched.The new version of Zocor (simvastatin) will be marketed by Johnson & Johnson MSD under the brand name Zocor Heart-Pro.

In a ground-breaking move in May, the British government approved the switch from prescription to over-the-counter status, arguing that easier access would allow more people to protect themselves from the risk of coronary heart disease.

The 10-milligram daily pill is designed for people at moderate risk of heart disease, defined as those with a 10% to 15% risk of a heart attack in the next 10 years. Pharmacists will be able to sell Zocor Heart-Pro to customers after asking about their situation and offering various health tests to ensure it is safe to give them the drug. A cholesterol test will be offered but is not compulsory.

In the United States, Zocor has patent protection until 2006 and Merck is focusing there on seeking OTC status for an older statin called Mevacor.

DRUG INDICATIONS / WARNINGS

FDA Approves Atorvastatin (Lipitor) to Prevent Cardiovascular Disease

The Food and Drug Administration approved Pfizer Inc.'s cholesterol drug Lipitor (atorvastatin calcium) to be used to reduce the risks of heart attack, chest pain and revascularization procedures in people with normal to mildly elevated levels of cholesterol who have other risk factors for heart

disease.

 

Regulators based their decision on a trial involving more than 10,300 patients who had normal or borderline cholesterol and no prior history of heart disease, but who had high blood pressure and at least three other known risk factors for heart disease, such as family history, age older than

55 years, smoking and diabetes.

 

The trial results showed Lipitor, given at its lowest dose of 10 mg, reduced the relative risk of heart attack by 36 percent compared with placebo. The trial was halted two years ahead of schedule "because of the significant benefits seen with Lipitor early in the trial," Pfizer said in a press release.

Acetaminophen Linked to Slight Decline in Renal Function 

Lifetime use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) did not cause a decline in renal function, but acetaminophen slightly increased risk, according to the results of an analysis from the Nurses' Health Study published in the July 26 issue of the Archives of Internal Medicine.

A total of 1,697 women enrolled in the Nurses' Health Study completed a questionnaire in 1999 about lifetime use of acetaminophen, aspirin, and NSAIDs and provided blood samples in 1989 and 2000. Multivariate logistic regression was used to determine the odds of developing the main outcome of change in estimated glomerular filtration rate, or creatinine clearance, (GFR) for 11 years, based on lifetime analgesic intake.

Mean estimated GFR decreased from 88 + 17 mL/minute per 1.73 m2 in 1989 to 79 + 17 mL/minute per 1.73 m2 in 2000. At baseline or after 11 years, there were no substantial differences in the unadjusted or estimated GFR levels among the categories of lifetime intake for the three analgesic groups.

Aspirin and NSAID use were not associated with an increased risk of GFR decline. However, acetaminophen use was associated with an increased risk of GFR decline of at least 30 mL/minute per 1.73 m2 (P for trend = .01) and of a GFR decline of 30% or more (P for trend < .001). For women consuming more than 3,000 g of acetaminophen, multivariate-adjusted odds ratio for a decline in GFR of at least 30 mL/minute per 1.73 m2 was 2.04 (95% confidence interval, 1.28 to 3.24) compared with women consuming less than 100 g.

Ciclopirox Shampoo for Treating Seborrheic Dermatitis

Seborrheic dermatitis is a common inflammatory skin disease, affecting between 1% and 3% of immunocompetent adults. While its cause is unknown, a number of predisposing factors have been reported, including the implications of Malassezia yeasts. Various treatment options are available, such as ciclopirox shampoo, which combines anti-Malassezia activity with an anti-inflammatory action. This agent has been shown to be an effective and safe treatment for seborrheic dermatitis of the scalp.

 

Clinically, seborrheic dermatitis presents as red, flaking, slightly greasy-looking patches, which are located primarily on the scalp, nasolabial folds, ears, eyebrows and chest. Due to the fact that there is an increased prevalence of seborrheic dermatitis in HIV-positive and AIDS patients, it is thought that the disease may be caused by an abnormal immune response to Malassezia.

 

The two main classes of treatment for seborrheic dermatitis are topical corticosteroids and antifungal agents. Corticosteroids reduce inflammation, thus resulting in clinical improvement of seborrheic dermatitis. Because of the adverse effects associated with topical steroids, there has been a shift in treatment strategies for seborrheic dermatitis with an increased interest in antifungal agents.

 

Ciclopirox shampoo 1% is an antifungal agent with antibacterial and anti-inflammatory properties. In placebo-controlled trials, ciclopirox has been shown to reduce signs and symptoms of erythema, scaling, and pruritus in 93% of the ciclopirox shampoo-treated patients compared to 41% in the placebo group (P<0.00001). It is a colorless, translucent solution, which has been used in the treatment of seborrheic dermatitis that is applied after wetting hair. Treatment should be repeated twice per week for 4 weeks, with a minimum of 3 days between each application.

PATIENT CARE INFORMATION

 

Flu Season 2004-2005 Strategy

The Centers for Disease Control and Prevention (CDC) has released the 2004-2005 recommendations for influenza immunization, prevention, and treatment (http://www.cdc.gov/mmwr/preview/mmwrhtml/rr53e430a1.htm).  Most of the recommendations are consistent with those outlined in 2003.  The primary target groups recommended for annual vaccination are 1) persons at increased risk for influenza-related complication (e.g. those ³ 65 years, children aged 6 – 23 months, pregnant women, and persons of any age with certain chronic medical conditions), 2) persons 54-64 years because this group has an elevated prevalence of certain chronic medical conditions, and 3) persons who live with or care for persons at high risk, including health care workers and family members.  Influenza vaccination is associated with reductions in respiratory illness and physician visits among all age groups, hospitalizations and death among persons at high risk, otitis media among children, and work absenteeism among adults.   Influenza vaccination remains the cornerstone for the control and treatment of influenza illness.  Optimal vaccination time is October and November, however the flu season can last through March and adults develop peak antibody protection against influenza infection 2 weeks after vaccination. Antiviral medications play a role in selected populations and circumstances.

 

Primary Changes and Updates in the 2004-2005 CDC Recommendations

 

1.                   Healthy children aged 6-23 months and close contacts of children in those ages, should be vaccinated against influenza.

2.                  Inactivated vaccine is preferred over live, attenuated influenza vaccine (LAIV, i.e. FluMist) for vaccinating household members, health-care workers, and others who have close contact with severely immunosuppressed persons during periods when such persons require care in a protected environment. Recipients of LAIV should refrain from contact with immunosuppressed persons for 7 days following receipt of the vaccine.

 

3.                  Severely immunocompromised individuals should not administer LAIV.

 

4.                  The 2004-2005 trivalent vaccine virus strains are

 

·               A/Fujian/411/2002(H3N2)-like,

·               A/NewCaledonia/20/99 (H1N1)-like, and

·               B/Shanghai 361/2002-like antigens. 

 

Manufacturers may substitute A/Wyoming/3/2003 for A/Fujian and B/Jilin/20/2003 or B/Jiangsu/10/2003 for B/Shanghai strains.

 

Considerations for Adults Aged ³ 65 Years

Persons ³ 65 years of age should all receive inactivated influenza vaccine. Older persons and persons with certain chronic conditions might develop lower postvaccination antibody titers than healthy young adults and thus can remain susceptible to influenza-related upper respiratory tract infection. A randomized controlled trial among noninstitutionalized persons greater than or equal to 60 years of age reported a vaccine efficacy of 58% against influenza respiratory illness, but indicated that efficacy might be lower among those aged ³ 70 years. Among elderly persons not living in nursing homes, influenza vaccine is 30 – 70% effective in preventing hospitalization for pneumonia and influenza.  Among older persons who do reside in nursing homes, influenza vaccination is most effective in preventing severe illness, secondary complications, and death. In nursing home residents, the vaccine can be 50 – 60% effective in preventing hospitalization or pneumonia, and 80% effective in preventing death, although the effectiveness in preventing influenza illness often ranges from 30 – 40%.  LAIV is not indicated for use in persons older than 50 years.

Antiviral agents are effective for treatment of influenza infection and chemoprophylaxis of exposed persons, including those ³ 65 years of age.  However, dosage reductions are recommended for nursing home residents and those with renal impairment (table).

 

The Role of Antiviral Agents for Treatment

Amantadine and rimantadine are adamantanes with activity against influenza A but not B viruses. The neuraminidase inhibitors zanamivir (Relenza) and oseltamivir (Tamiflu) are effective for treatment of uncomplicated infections of both influenza A and B viruses.  When administered within 2 days of illness onset to otherwise healthy adults antiviral drugs can reduce the duration of uncomplicated influenza illness by approximately 1 day, compared to placebo.

Data are limited regarding the effectiveness of the four antiviral agents in preventing serious influenza-related complications. Oseltamivir (Tamiflu) treatment of influenza illness has been shown to reduce antibiotic use and lower respiratory tract complications such as bronchitis and pneumonia in otherwise healthy young adults and those at risk due to underlying conditions and/or age greater than 65 years (Kaiser et al. Arch Intern Med 2003;163:1667-72).

The Role of Antiviral Agents for Chemoprophylaxis Following Exposure

Chemoprophylaxis is not a replacement for vaccination. Amantadine and rimantadine are 70-90% effective in preventing illness from influenza A but not influenza B infection. The adamantanes can prevent or blunt clinical illness while permitting the development of protective antibodies to circulating influenza viruses. Both drugs have been shown to decrease nursing home outbreaks of influenza A.  As many as one third of influenza A strains are resistant to adamantanes.

Among the neuraminidase inhibitors, only oseltamivir (Tamiflu) has been approved for chemoprophylaxis although in community studies both neuraminidase inhibitors have demonstrated an efficacy rate of 82 – 84% in preventing laboratory confirmed influenza. A six-week study in nursing home residents reported a 92% reduction in influenza illness with the use of oseltamivir prophylaxis.

Persons at high risk of infection who have been vaccinated should be considered for chemoprophylaxis.  During an outbreak, persons who have NOT been vaccinated, should receive the vaccine and receive chemoprophylaxis to cover the exposure for the two weeks before the vaccine is effective. The table outlines dosing considerations for antiviral medications in elderly nursing home residents.

Recommendations

1.       Education regarding appropriate influenza prevention, vaccination, chemoprophylaxis and treatment should be provided in September.

2.       All residents should be vaccinated against the 2004-2005 strains of influenza.

3.       All employees should be vaccinated against the 2004-2005 strains of influenza.

4.       If a resident develops influenza, he/she should be treated with either rimantadine or oseltamivir (Tamiflu) (see table).

5.       There are no head-to-head trials comparing rimantadine to oseltamivir (Tamiflu) for treatment or chemoprophylaxis of influenza A virus.

6.       Other exposed residents (same hallway, same healthcare workers) should undergo chemoprophylaxis with either rimantadine or oseltamivir (Tamiflu). Based on superior safety and equal efficacy over amantadine, rimantadine should be recommended when ONLY influenza A is suspected, or the resident is not a candidate for chemoprophylaxis or treatment with oseltamivir (Tamiflu).

7.       Most influenza outbreaks are associated with strains of influenza A, however, if influenza B is suspected or documented, residents should receive treatment and/or chemoprophylaxis with oseltamivir ONLY.  Rimantadine is NOT effective treatment for influenza B.
