April 20, 2011 - The 10 most prescribed drugs in the U.S. aren't the drugs on which we spend the most, according to a report from the IMS Institute for Healthcare Informatics.


The institute is the public face of IMS, a pharmaceutical market intelligence firm. Its latest report provides a wealth of data on U.S. prescription drug use.


Continuing a major trend, IMS finds that 78% of the nearly 4 billion U.S. prescriptions written in 2010 were for generic drugs (both unbranded and those still sold under a brand name). In order of number of prescriptions written in 2010, the 10 most-prescribed drugs in the U.S. are:


Hydrocodone (combined with acetaminophen) -- 131.2 million prescriptions

Generic Zocor (simvastatin), a cholesterol-lowering statin drug -- 94.1 million prescriptions

Lisinopril (brand names include Prinivil and Zestril), a blood pressure drug -- 87.4 million prescriptions

Generic Synthroid (levothyroxine sodium), synthetic thyroid hormone -- 70.5 million prescriptions

Generic Norvasc (amlodipine besylate), an angina/blood pressure drug -- 57.2 million prescriptions

Generic Prilosec (omeprazole), an antacid drug -- 53.4 million prescriptions (does not include over-the-counter sales)

Azithromycin (brand names include Z-Pak and Zithromax), an antibiotic -- 52.6 million prescriptions

Amoxicillin (various brand names), an antibiotic -- 52.3 million prescriptions

Generic Glucophage (metformin), a diabetes drug -- 48.3 million prescriptions

Hydrochlorothiazide (various brand names), a water pill used to lower blood pressure -- 47.8 million prescriptions.



The 10 Best-Selling Drugs


It shouldn't be a surprise that these generic drugs are not the ones bringing in the big bucks for pharmaceutical companies. The drugs on which we spend the most money are those that are still new enough to be protected against generic competition.


The IMS reports that Americans spent $307 billion on prescription drugs in 2010. The 10 drugs on which we spent the most were:


Lipitor, a cholesterol-lowering statin drug -- $7.2 billion

Nexium, an antacid drug -- $6.3 billion

Plavix, a blood thinner -- $6.1 billion

Advair Diskus, an asthma inhaler -- $4.7 billion

Abilify, an antipsychotic drug -- $4.6 billion

Seroquel, an antipsychotic drug -- $4.4 billion

Singulair, an oral asthma drug -- $4.1 billion

Crestor, a cholesterol-lowering statin drug -- $3.8 billion

Actos, a diabetes drug -- $3.5 billion

Epogen, an injectable anemia drug -- $3.3 billion



U.S. Prescription Drug Use: 2010 Factoids


Who's paying for all these drugs? Commercial insurance helped pay for 63% of prescriptions, down from 66% five years ago. Federal government spending through Medicare Part D covered 22% of prescriptions.


For Americans covered by insurance, Medicare, or Medicaid, the average co-payment for a prescription was $10.73 -- down a bit from 2009 due to increased use of generic drugs. The average co-payment for branded drugs for which generic alternatives were available jumped 6% to $22.73.


Other facts from the 2010 IMS report:


Doctor visits were down 4.2% since 2009.

Patients filled more than half of their prescriptions -- 54% -- at chain drugstores, possibly because of discounts on generic drugs.

Brands that lost their protection from generic competition led to $12.6 billion less spending in 2010 than in 2009.

The price increase for drugs without generic competition led to $16.6 billion more spending in 2010 than in 2009.

Drug companies offered $4.5 billion in rebates to assist patients with the high cost of brand name drugs for which there was no generic alternative.




Vicodin is #1. The whole darn country is in pain. :o


And then we wonder why the majority of Michigan medical cannabis recommendations are for severe and chronic pain! People are sick of being hooked on hydrocodone.
