Top 200 Drugs of 2012

Author: Michael Bartholow, PharmD, CACP


This analysis of the top 200 drugs by prescriptions dispensed and total sales reveals key trends in today's pharmaceutical market.
Significant changes in health care utilization contributed to declining costs and slow spending growth of prescription drugs in the United States in 2012. Overall health care spending outpaced prescription drug spending and is likely to continue to do so for the next several years. The impact of recent changes has resulted in a dichotomy between the reduction of overall drug costs and increasing patient costs for specialty drugs.

Top Performers

The top 5 drug classes in terms of spending were oncologics ($25.9 billion), mental health ($23.5 billion), respiratory agents ($22.1 billion), antidiabetics ($22 billion), and pain ($18.2 billion). Patent expiries among oncologic agents resulted in a $744 million drop in spending, while spending on targeted agents grew by $2.5 billion. Spending on mental health agents declined by $6.2 billion, as top agents Zyprexa (olanzapine), Seroquel (quetiapine), Geodon (ziprasidone HCl), and Lexapro (escitalopram) lost patent protection. Antihypertensives were highest in prescription volume, followed by pain and mental health medications, antibacterials, and lipid regulators.

The top-earning single agent based on non-discounted spending was Nexium (esomeprazole) ($6 billion), followed by Abilify (aripiprazole) ($5.9 billion), Crestor (rosuvastatin calcium) ($5.1 billion), Advair Diskus (fluticasone propionate and salmeterol) ($4.9 billion), and Cymbalta (duloxetine delayed-release capsules) ($4.7 billion). Lipitor (atorvastatin calcium) was the top-earning agent of 2011, accounting for $20.1 bil-lion in total sales, but it lost its patent in November 2011. Subsequently, Lipitor was not among the top 20 earning agents in 2012. The newly available generic alternative to Lipitor, atorvastatin, was ranked number 21 last year, but earned almost $17 billion less than the brand product did in 2011.

Health Care Utilization

In 2012, the overall decline of per capita utilization of prescription medications and health care services highlights notable trends in health care spending. The total number of outpatient office visits, which are the lowest-cost medical interventions, declined for a third straight year, although the 0.9% decrease seen in 2012 was a significantly smaller drop than seen in 2010 or 2011. Nonemergency hospitalizations, outpatient treatment, and per capita medication use also declined, while emergency department admissions increased sharply.

Another important trend is the allocation of health care spending. Among privately insured health plan members, over 51% of total health care spending was concentrated among the top 5% most expensive members. Conversely, the bottom 50% of health plan members accounted for only about 3% of total spending. The latter group had a higher concentration of its costs attributed to pharmacy benefits, and thus this group was positively impacted by the increasing number of generic alternatives that have come to market following the large number of patent expiries in recent years.

For members with chronic or oncologic conditions, approximately 52% of total spending was attributed to outpatient medical costs while pharmacy costs for each group were 24.8% and 15.4%, respectively. For members with autoimmune or other specialty conditions, outpatient medical accounted for 32.4% of spending, and pharmacy spending was 45.2% of total spending.

Medication Spending and Growth

Nominal drug spending in 2012 totaled $325.8 billion, representing a 1% drop from the prior year. There was a nominal increase in prescription volume of 1.2% last year, but that equates to a 0.1% decline when adjusted on a per capita basis. Still, this is an improvement over the previous year, which showed a 1.1% decline in per capita utilization.

Areas of the largest volume gains in medication utilization included mental health, nervous system disorders, pain, and respiratory agents. The largest declines were seen in allergy therapies, antibacterials, and osteoporosis agents. Adults older than 50 years consumed the largest amount of medication last year, accounting for 64% of prescriptions dispensed. Adults aged 26 to 49 years and individuals 18 years and younger accounted for the largest decline in medication utilization. Prescription utilization among individuals aged 19 to 25 years also declined in 2012, in contrast to the increased utilization seen in 2011 when the provision of the Affordable Care Act allowing them to remain on their parents’ health insurance took effect. It remains to be seen whether the decrease in prescription drug utilization will positively or negatively impact overall health care costs in the future.

Spending on brand-name medications dropped by $11.4 billion, reaching a total of $230.2 billion. The decrease in the volume of brand name prescriptions accounted for a $3.9 billion reduction in spending, while the loss of patent exclusivity of some products resulted in a $28.9 billion decline. Spending for new brands grew by $5.6 billion, and price increases on existing brand products raised spending another $15.7 billion.

Generics represent 84% of total prescriptions dispensed in 2012 and 28% of total spending. Currently in the retail setting, when a generic option is available, it is dispensed in place of brand products 95% of the time. Over the past decade, generic prescription volume has risen by 30%, although this growth is not expected to exceed 87% of total prescriptions dispensed through 2017 due to fewer upcoming patent expiries compared with previous years.

Patient Costs

Changes in health insurance plans have caused significant shifts in patient costs for prescription medications. Traditional health care plans, such as PPOs and HMOs, are now carrying significantly higher deductibles. Consumer-driven health plans, which combine high deductibles with coinsurance costs of 20% or more after deductibles, have become more popular and currently represent 19% of insured patients. Patient costs correlate directly with treatment adherence and compliance, which can dramatically impact overall clinical outcomes.

While out-of-pocket health care costs are rising overall, prescription drug costs are decreasing for most patients as a result of the increased utilization of generics. Health care deductibles increased by 48% in 2012, averaging $818 per patient. Pharmacy copays and coinsurance actually decreased, dropping from $123 per patient in 2011 to $121 in 2012. Nearly 72% of all prescriptions dispensed in the retail setting had an average copay of $10 or less. Medicare Part D prescriptions cost less than $10 approximately 84% of the time, while 99% of Medicaid prescriptions cost less than $10. Drugs with the highest out-of-pocket costs were biologics and specialty drugs, which account for 3% of the total retail prescriptions dispensed in 2012.

Trends to Watch

In 2012, 28 new molecular entities (NMEs) were launched, which continues the trend seen over the past several years. Several agents with new mechanisms of action in their respective therapy classes became available, including treatments for chronic kidney disease, multiple sclerosis, and HIV. Additionally, 7 orphan disease medications were launched, offering new therapy options for rare diseases affecting fewer than 200,000 patients, such as cystic fibrosis, chronic myeloid leukemia, and Gaucher disease. Nine oncology NMEs were released last year, which was the highest number in the past decade.

It is likely that growing availability of new agents and treatment options for a number of diseases will continue into the next few years. The 2012 FDA Safety and Innovation Act included a provision for the designation of Breakthrough Therapies, which can lessen the burden of the development and review processes for some new medications aimed at treating serious diseases. Additionally, there are several highly anticipated agents on the horizon that have been approved or that are expected to gain FDA approval in 2013. Kadcyla (ado-trastuzumab emtansine) was approved in February 2013 and has been called the “smart bomb” for breast cancer. Invokana (canagliflozin) is the first agent approved in a new class of agents targeting type 2 diabetes. Tecfidera (dimethyl fumarate) is a newly approved oral agent targeting multiple sclerosis. Several new oral hepatitis C regimens are expected to be approved in late 2013 and in 2014.

The decline in prescription drug sales may be the product of drug therapy optimization and streamlining, which would ultimately lead to improved outcomes. Alternatively, this decline may also reflect a tendency for some patients to defer health care costs and preventive treatments, leading to more advanced complications and ultimately higher health care costs. Changes in health care coverage may benefit the majority of patients using low-cost generics for the most commonly treated disease states, but there will likely continue to be a small segment of patients facing large out-of-pocket expenses for specialty medications treating specific conditions.
