Patients with cheaper drugs tended to take their medicine more consistently
A new study in the Annals of Internal Medicine found that the cost difference between generic and brand-name drugs seems to be a big factor when it comes to sticking with a medication–especially when it comes to statins, one of the most-prescribed drugs in the country. People who got the generic versions of the cholesterol-lowering medication were more likely to consistently take it and avoid cardiovascular disorders than those who filled the brand-name kind.
“Initiating a generic versus a brand-name statin seems to be associated with lower out-of-pocket costs, improved adherence to therapy, and improved clinical outcomes,” the study said.
The study, which looked at more than 90,000 patients over age of 65, found that people taking generic drugs were more likely to stick to their medication regimen. Price played a role in this disparity, the study suggests. The average cost to fill a prescription for the consumer was $10 for generic statins versus $48 for brand names.
“Given this substantial cost difference, it is perhaps not surprising that adherence and cardiovascular outcomes were worse among patients receiving brand-name statins,” study authors wrote. Overall, people who took generic drugs had 8% fewer incidents than people who used brand-name drugs.
The study received grant support from drug manufacturer Teva Pharmaceutical (which makes both generic and brand-name drugs) and acknowledges that the results may not be generalizable for certain populations: particularly those with greater incomes or access to insurance plans that provide better coverage for brand-name drugs.
