Dec. 31, 2012 ? Generic drugs now comment for over 70 percent of prescriptions dispensed. However, while general drugs are clinically bioequivalent to a brand-name version, they mostly differ in their earthy characteristics, such as tone and shape. Researchers from Brigham and Women’s Hospital (BWH) have found that some patients who accept general drugs that change in their tone are over 50 percent some-more expected to stop holding a drug, heading to potentially critical and potentially inauspicious clinical effects.
The investigate will be published online Dec. 31, 2012 in a Archives of Internal Medicine.
“Pill coming has prolonged been suspected to be related to remedy adherence, nonetheless this is a initial experimental investigate that we know of that directly links pills’ earthy characteristics to patients’ confluence behavior,” explained Aaron S. Kesselheim MD, JD, MPH, partner highbrow of medicine in a Division of Pharmacoepidemiology and Pharmacoeconomics during BWH, and principal questioner of this study. “We found that changes in tablet tone significantly boost a contingency that patients will stop holding their drugs as prescribed.”
The researchers conducted a case-control investigate of patients holding antiepileptic drugs and compared a contingency that patients who did not refill their remedy had been given pills that differed in tone or figure from a before prescriptions. Using a vast inhabitant database of filled prescriptions, when a researchers identified a mangle in a patient’s use of a drug, they looked during a prior dual remedy fillings to see if they were a same tone and shape. They found that interruptions in a remedy stuffing occurred significantly some-more frequently when a pills had opposite color. Interruptions in antiepileptic drug use for even a few days can lift a risk of seizure and have critical medical and amicable consequences for patients.
These commentary offer critical take-home messages for physicians, pharmacists, and patients. As Kesselheim explained, “Patients should be wakeful that their pills competence change tone and shape, though that even differently-appearing general drugs are authorized by a FDA as being bioequivalent to their brand-name counterparts and are protected to take. Physicians should be wakeful that changes in tablet coming competence explain their patients’ non-adherence. Finally, pharmacists should make a indicate to tell patients about a change in tone and figure when they change general suppliers.”
Researchers acknowledge that remedy confluence is a multi-faceted issue, though advise that holding stairs to assent (or even require) likeness in tablet coming among bioequivalent code name and general drugs competence offer a comparatively elementary approach to minister to improved adherence.
This investigate was upheld by a career growth endowment from a Agency for Healthcare Research Quality (K08HS18465-01), and a Robert Wood Johnson Foundation Investigator Award in Health Policy Research. Dr. Choudhry has perceived unlimited investigate grants from CVS Caremark, Aetna, a Commonwealth Fund, and a Robert Wood Johnson Foundation to investigate remedy adherence. Dr. Shrank has perceived unlimited investigate appropriation from CVS Caremark, Aetna, Teva, Lilly, and a National Association of Chain Drug Stores.
