Apixaban (Eliquis) had the lowest overall risks out of direct oral anticoagulants (DOACs) versus warfarin (Coumadin) in a large study.

Researchers at the University of Nottingham in the United Kingdom set out to investigate the associations between DOACs and risks of bleeding, ischemic stroke, venous thromboembolism, and all-cause mortality compared with warfarin, in the 

Using two UK primary care databases-QResearch and Clinical Practice Research Datalink (CPRD) -the researchers evaluated 132,231 patients taking warfarin, 7,744 on dabigatran, 37,863 on rivaroxaban, and 18,223 on apixaban without anticoagulant prescriptions for twelve months before study entry. The patients were subgrouped into 103,270 with atrial fibrillation (AF) and 92,791 without AF.

Apixaban was found to be the safest drug, with reduced risks of major, intracranial, and gastrointestinal bleeding compared with warfarin, the researchers state.

“Anticoagulants are prescribed for a wide range of indications although the adverse events have been studied mostly in patients with atrial fibrillation. Our study has shown that the risk of major bleeding is lower in patients taking apixaban-regardless of the reason for prescribing,” writes Yana Vinogradova, PhD, research statistician in the School of Medicine at the University of Nottingham.

In patients with atrial fibrillation, apixaban was associated with a lower risk of major bleed than warfarin and rivaroxaban (Xarelto). Dabigatran (Pradaxa) and apixaban were associated with lower risks of intracranial bleed than warfarin, and rivaroxaban was associated with a higher risk of intracranial bleeding compared to apixaban.

In the subgroup of patients without AF, apixaban was associated with lower risks of major bleed (adjusted hazard ratio 0.60) than warfarin or rivaroxaban. Rivaroxaban was associated with a lower risk of intracranial bleed (0.54) compared with warfarin, and apixaban use resulted in lower risks of all gastrointestinal (0.55) and upper gastrointestinal bleeds (0.55).

The risk of primary ischemic stroke did not differ between any of the anticoagulants studied. In addition, the risk of primary venous thromboembolism in patients with AF was not different between any drugs. However, in the group without AF compared with warfarin, there was a higher risk in patients taking rivaroxaban and lower risks in patients taking dabigatran.

For both patients with and without AF, the risk of mortality was increased in patients taking rivaroxaban compared with warfarin, the researchers find. “Both rivaroxaban and low-dose apixaban were associated with increased risks of all-cause mortality compared with warfarin,” they write.

An important limitation of the study is the lack of information on patient adherence to their prescribed drugs, according to Vinogradova. “It is not known when exactly a patient stopped taking anticoagulants … Warfarin has been shown to have the highest non-persistence [adherence rate] and apixaban and rivaroxaban the lowest.”

Study Shows Comparative Risks for DOACs

	Sometimes, despite your best efforts, you can't stay up on the latest news. Staying up on local and national politics is hard enough, but what about the latest pharmacy news? Almost impossible.

That's why every month we bring you Small Doses. They're easy-to-swallow little pills (candy-coated!) of information tailored for the busy pharmacist. There's a lot happening out there, but here's the short version of what we think you need to know. 

	This month, read more on depression in the pharmacy, vaccine errors, naloxone, and more. And when you're done, hopefully you'll be well-versed enough to share the news around the water cooler-

assuming you even have time for a water break

	Up next: More pharmacy residents depressed than medical residents.

	More Pharmacy Residents Depressed than Medical Residents

	Pharmacy residents typically carry a high stress load and can become depressed, but more accurate data on depression rates are needed. “We haven’t really studied this a lot,” says Janet A. Silvester, PharmD, vice president of accreditation services for 

. “On the medical side, they have been looking at [the impacts of stress on residents] longer.”

	To obtain more accurate data on pharmacy resident stress, Evan Williams, PharmD, BCPS, assistant professor of pharmacy practice at 

 in Henderson, NV, along with pharmacists who work for Albertsons and Rite Aid, surveyed more than 1,900 pharmacy residents using the depression screening component of the Patient Health Questionnaire (PHQ-9).

, published in the March 2018 issue of the 

American Journal of Health-System Pharmacy

, found 39% reported moderate to severe depressive symptoms during March 2016. Rates among medical residents have been reported to be about 30%. In the general population, the depression rate ranges from 6.6% to 7.6%.

	“The rate was higher than what I expected,” says Williams.

	Now, he and his colleagues are working to reproduce the results in a two-year study, surveying pharmacy residents about their 

 rates at various times of the year. “Hopefully, we are able to publish this and get more of a cluster of data, to describe how frequently we think this is happening,” Williams says.

Pharmacy School Helps Community with Naloxone Training

 at Auburn University in Alabama is looking to expand the 

	The school’s pharmacy residents and pharmacists are supplying the city’s police and firefighters with naloxone, and training them to use the opioid overdose reversal medication.

	“The Auburn pharmacy faculty and students are working to be proactive, and prepare the Auburn community to react and respond if and when the United States opioid epidemic extends to the Auburn community,” says Kimberly Braxton-Lloyd, PharmD, assistant dean in Auburn’s Department of Pharmacy Health Services. “We want to increase awareness and preparedness among our students, faculty, advisors, and first responders, so we can act quickly and decisively in emergencies and potentially save lives.”

	Braxton-Lloyd is working to raise funds for 

. “We would like to continue to expand this program to further educate and equip others who may be in a position to respond during an opioid overdose,” Braxton-Lloyd says. “We believe the more people who are trained and equipped throughout campus, the more likely it will be that we are prepared when an overdose situation does occur on our campus.”

	Alabama leads the country in opioid prescribing, according to the CDC, with an estimated 96 to 142 prescriptions per 100 people per year.

	Specialty drugs will contribute all of the growth in drug spending in 2018. In fact, these medicines are expected to reach 48% of total spending in developed markets by 2022, according to a 

 from the IQVIA Institute for Human Data Science.

	This year, the $318 billion specialty medicines market will represent 41% of developed market spending, up from $172 billion in 2013, IQVIA said in its 

2018 and Beyond: Outlook and Turning Points 

study. However, the growth of spending on specialty medicines will be constrained by cost and access controls and a greater focus on assessments of value, IQVIA notes.

Considering Specialty Pharmacy? Make Your Move

	Biosimilar drugs will also have a much bigger impact on drug spending in 2018 and beyond. In 2018, $19 billion of current biotech spending in developed markets will have competition from biosimilars for the first time. “That amount is significantly greater than the $3 billion in biosimilar revenue that became exposed in 2017, and it adds to the $26 billion already facing competition,” IQVIA says. “The new exposure to competition in 2018 is the largest single-year change to date and signals the start of the next large wave of biosimilars.”

	The study also found that real net per capita spending on medicines in the United States will decline in 2018 and continue almost unchanged at roughly $800 per person through 2022. “Spending will remain flat after factoring in the robust pipeline of new drugs, moderating brand price increases of 2% to 5% on a net basis (7% to 10% on a list price basis) and the impact of brand losses of exclusivity, which will be greater in the next five years than the last five,” according to an IQVIA statement.

	Patients taking over-the-counter medications such as acetaminophen reported less pain intensity than patients taking prescription opioids such as Vicodin, during a recent study.

, involved Veterans Affairs patients who had moderate to severe chronic back pain, or hip or knee osteoarthritis pain, despite analgesic use.

	Researchers compared patients’ pain intensity, pain-related function, and the adverse effects between opioids such as morphine, oxycodone, or fentanyl patches, versus nonopioids, including generic Tylenol, ibuprofen, and prescription nerve and muscle pain drugs.

	While the two groups did not significantly differ on pain-related function over a 12-month period, pain intensity was significantly better in the nonopioid group. The 

 (BPI) severity was 4.0 for the opioid group and 3.5 for the nonopioid group.

	Adverse medication-related symptoms were significantly more common in the opioid group over 12 months:1.8 in the opioid group versus 0.9 in the nonopioid group.

Treatment with opioids was not superior to treatment with nonopioid medications for improving pain-related function over 12 months,” the researchers wrote. “Results do not support initiation of opioid therapy for moderate to severe chronic back pain or hip or knee osteoarthritis pain.”

Errors Reported with Herpes Zoster Vaccines

	Confusion over the two herpes zoster vaccines on the market, has led to a “small number of error reports” involving differences between the two vaccines, the Institute for Safe Medication Practices (ISMP) reports.

 (zoster vaccine recombinant, adjuvanted) from GlaxoSmithKline, referred to as RZV by the CDC, was approved by the FDA last October. However, for more than 10 years, healthcare professionals have been accustomed to the storage and administration requirements of Merck’s Zostavax (zoster vaccine live, or ZVL).

	“Shingrix and Zostavax have different storage requirements, components/diluents, and routes of administration,” according to 

ISMP Medication Safety Alert! Community/Ambulatory Care Edition.

	Both components of the Shingrix vaccine, its lyophilized gE antigen component and its adjuvant suspension component, should be stored under refrigeration before and after reconstitution, according to ISMP. If the lyophilized component or its adjuvant suspension are improperly stored in a freezer, they must be discarded.

, the lyophilized vaccine (attenuated varicellazoster virus) should be stored in a freezer, and the Merck-supplied sterile water diluent can be stored in a refrigerator or at room temperature.

	“The product components are not interchangeable. A system should be employed to ensure the Shingrix lyophilized component and adjuvant suspension vials are stored with one another to reduce the risk of using a diluent from another vaccine,” ISMP says.

	Another major difference is that Shingrix is given intramuscularly, while Zostavax is given subcutaneously.

 (ACA) recently acquired the pharmacy buying group The Compounders Group (TCG) to help independent pharmacists stay competitive in today’s marketplace, ACA says.

	“The costs of running an independent pharmacy continue to escalate, especially with challenges like USP 800. It’s more important than ever that independent pharmacies work together,” says ACA Executive Vice President Donnie Calhoun, who is also a longtime member of TCG. “We will see more collaboration as TCG grows to an even larger, stronger group, leveraging its buying power and helping independent pharmacies face the challenging pharmacy landscape.”

	Since the acquisition, TCG has experienced an almost 20% increase in membership and has expanded to 52 vendors.

	“The founders of TCG have watched it grow over the past six years, from serving primarily compounders with an increasing number of members that own hybrid, specialty, and traditional pharmacies. With ACA at the helm, TCG’s goal of helping its members buy smarter and stronger will remain the same,” says David Rochefort, one of TCG’s five founding members.

ASHP: 340B Provides Access to Pharmacy Services

 lauded the benefits of the government’s 340B Drug Discount Program during a Senate hearing on drug pricing in mid-March.

	“The increasing shift throughout healthcare toward ambulatory care, including more outpatient pharmacy services, has contributed to the growth of the 340B program and has allowed for better access to medications by low-income and uninsured patients,” Joe Hill, director of 

, told the Senate Health, Education, Labor, and Pensions Committee. “It is important to note that drugs subject to the 340B drug-pricing program make up a fraction of the nation’s total drug expenditures.”

	The 340B program also reduces government expenditures and lessens the burden on taxpayers who would otherwise be financing the indigent care federal 340B-participating hospitals provide, said Hill. He added that the 340B program results in savings that:

		Improve access to primary care, behavioral health services, and pharmacist-led substance abuse treatment;

		Enable discounts or free prescription medications; and

		Provide many other services for uninsured and underinsured patients.

Easy-to-swallow bits of news and studies for the busy pharmacist.

Small Doses: News for Pharmacists in April

	The Centers for Medicare & Medicaid Services’ new Medicare Part D proposal calls for a seven-day supply limit on opioid prescriptions and other efforts to help battle the opioid epidemic.

, which would go into effect in 2019, includes new hard formulary levels at pharmacies that would restrict the amount of initial fills on prescription opioids to seven days for the treatment of acute pain with or without a daily dose maximum (such as 50 MME).

	CMS would also expect all sponsors to implement soft POS safety edits (which can be overridden by a pharmacist) based on duplicative therapy of multiple long-acting opioids, and request feedback on concurrent prescription opioid and benzodiazepine soft edits, the agency said in a 

	CMS also proposes enhancing the Overutilization Monitoring System (OMS) by identifying high risk beneficiaries who use “potentiator” drugs such as gabapentin (brand names Neurontin, Gralise, and others) and pregabalin (brand name Lyrica) in combination with prescription opioids to “ensure that plans provide appropriate case management,” CMS said.

	OMS already flags concurrent benzodiazepine use by plan enrollees.

 executives have not been able to fully review the proposal, the organization in general advocates for “a change in public policy to create a seven-day supply limit for initial opioid prescriptions issued for acute pain, which is consistent with the Centers for Disease Control and Prevention (CDC) Guideline for Prescribing Opioids for Chronic Pain,” Chris Krese, spokesman for NACDS, told 

	“CDC’s clinical evidence suggests that a greater amount of initial opioid exposure is associated with a greater risk for long-term use and addiction. More than 20 states already have taken action, and federal action is needed for consistent patient care,” Krese added.

	Meanwhile, NACDS is reviewing the exact details of CMS' Medicare Part D, to determine if they are consistent with NACDS’s position. “Following that review, NACDS will submit comments to CMS,” Krese said.

	In related news, the National Conference of Pharmaceutical Organizations (NCPO) 

 “immediate action on components of the President’s Commission on Combating Drug Addiction and the Opioid Crisis report” and requested the opportunity to dialogue with the President and others in the Administration for continued collaboration on opioid-related issues.

	The coalition of 11 trade associations and professional societies includes NACDS, NCPA, ASHP, and APhA.

	“Pharmacy has significant insights about the complexity of this issue, given the role of pharmacists on the front lines of healthcare every day, and we are committed to working proactively with NCPO members and with all levels and branches of government for the safety of our families and communities,” said NACDS President and CEO Steven C. Anderson.

Pharmacy groups are praising new Medicare Part D opioid limits.

	The Flu’s Impact on IV Saline Shortages

	This year’s severe flu season may continue to further impact the IV saline shortage, which worsened last fall after Hurricanes Maria and Irma struck Puerto Rico. “The tight supply of saline products has been exacerbated by an increased demand for saline we’re seeing as a result of the worse-than-typical flu season. ... As such, we encourage healthcare organizations and hospitals to

	Cannabidiol Drug for Epilepsy Expected Later This Year

 therapy-the first in a new category of antiepileptic drugs-is expected to launch in the second half of this year, after its manufacturer’s New Drug Application was accepted by FDA.

	Epidiolex, manufactured by GW Pharmaceuticals, demonstrated a reduced monthly drop in seizure frequency compared to placebo in highly-treatment-resistant patients with Lennox-Gastaut syndrome (LGS), a rare form of epilepsy, according to a study published in 

. Over a 14-week treatment period, 44% of patients taking Epidiolex saw a significant reduction in seizures, compared with 22% of the placebo group.

	"LGS is one of the most difficult types of epilepsy to treat, and the majority of patients do not have an adequate response to existing therapies," said Elizabeth Thiele, MD, PhD, a professor of Neurology at Harvard Medical School, and lead author of the Lancet study. "These results show that Epidiolex may provide clinically meaningful benefits for patients with LGS."

	FDA accepted the NDA for Epidiolex to treat LGS and Draven syndrome, another rare childhood-onset epilepsy, in December.
