According to the Centers For Disease Control and Prevention (CDC), nearly half of U.S. adult population takes at least one drug that requires a prescription while almost 11 percent takes five or more prescription drugs. In fact, nearly 20 percent of the nation’s health care costs are from drug expenses.
Prescription drug costs are predicted to increase by 11.6 percent in 2017, at an even quicker pace than the 11.3 percent increase in 2016. Pfizer Inc, one of the largest pharmaceutical companies, raised prices on 133 of its brand-name products in 2016, with more than three-quarters of those increases being over 10 percent. Drug use is predicted to reach 4.5 trillion doses by 2020, costing around $1.4 trillion.

So which drugs are considered the top-selling prescriptions? According to the Motley Fool, the top ten drugs sold from 1996 to 2016 were:
The total lifetime earnings of these top ten drugs is worth over 800 billion dollars. In 2016 alone, Lipitor generated $1.76 billion in sales, pushing its lifetime sales to $148.7 billion. Keep in mind that these sales aren’t just limited to the U.S.
Four out of the top ten selling prescriptions in the U.S. increased in price by more than 100 percent since 2011 while six others increased by over 50 percent. In 2014, sales for the top 10 prescriptions went up 44 percent in 2014, even though prescriptions for the medications dropped 22 percent.
General Use of Prescription Drugs
According to CDC, the most regularly prescribed drug classes are pain killers, lipid-lowering agents, and antidepressants. In 2010, 78 percent of prescriptions filled were for those with chronic illnesses, ranging from diabetes to cancer. Specialty drug therapy for cancer, auto-immune and other chronic illnesses represented around 17 percent of total pharmacy spending.
