Dr Jones, would you use these Wompicillin drug samples if I take you to a baseball game in a luxury box catered by Alfredo’s?
Sure, I love drug samples. I’ve been wanting to try Wompicillin.
Dr Jones, would you use these drug samples if I bring lunch to your office?
Okay, as long as you bring enough lunch for the nurses.
Dr Jones, would you use these drug samples if I just leave some pens in your waiting room?
What kind of physician do you think I am?
Dr Jones, I know what kind of physician you are… we’re just haggling over the price.
The pharmaceutical industry spends billions of dollars each year on drug promotion. A common method of promotion is through drug detailing, in which an individual pharmaceutical representative meets with one or more physicians to discuss their products. These meetings may include travel, sporting or cultural events, conferences, or meals, and often involve gifts from the drug representative to the physician. Gifts may include pens, pads, clocks, watches, bags, calendars, golf balls, shotgun shells, mugs, books, or artwork. These meetings also typically involve the exchange of information verbally and through printed material about the drug. Although the mock dialogue presented above may overstate the problem with interactions between physicians and pharmaceutical representatives, there is genuine concern that these are ethically problematic relationships.
In this issue of the Journal Backer and colleagues1 provide evidence for a wide range of community family physician behaviors involving drug representatives, gifts from pharmaceutical companies, and use of medication samples. Interactions between drug representatives and physicians varied between and within the practices studied. A large number of the practices had formal methods for meeting with these representatives, and several scheduled patient appointment times to meet with them. Gifts varied from pens and candy to meals and tickets to a musical. Medication sample use varied between physicians, but, on average, samples were given in nearly 1 in 5 patient visits.
I contend that the relationship between the physician and the drug representative has more to do with changing physicians’ prescribing patterns than with providing good patient care. However, the language used in this article provides the subtle message that drug samples, gifts, meals, treats, and educational materials are beneficial, but I believe each of these particular benefits is loaded with problems.
Drug samples
The use of medication samples varied widely between and within practices in the study by Backer and colleagues. Although the authors describe physicians who distribute more samples as sensitive to the needs of their patients, they did not measure physician sensitivity or the needs of the patients or the community. The sample types that were distributed represent a wide range of treatments; antibiotics, anti-inflammatory drugs, and antihypertensives were among the most frequently dispensed samples. A quick review of the samples in an office I visited last week revealed only the newest and most expensive formulations of these medicines. There was no sulfamethoxazole-trimethoprim, amoxicillin, hydrochlorothiazide, or ibuprofen. There was plenty of cefuroxime, valsartan, and rofecoxib. Indiscriminant use of the newest antibiotics will certainly exacerbate the crisis of drug-resistant bacteria. Of particular concern is the distribution of samples for chronic illness. For example, a newly diagnosed hypertensive patient is started on amlodipine therapy because there is an “ample supply” in the drug cabinet. However, the evidence still recommends b-blockers and diuretics as first-line therapy for hypertension. A recent study found that despite the evidence and the recommendations of the Joint National Committee on the Detection, Evaluation, and Treatment of High Blood Pressure3 the number of prescriptions for b-blockers and diuretics have dropped, while the number of prescriptions for calcium channel blockers have increased. Calcium channel blockers now represent 38% of antihypertensive medication prescriptions compared with 11% for b-blockers and 8% for diuretics.3
Are drug samples really the best method for providing medicine to those with low income? If samples are given according to what is in the closet, what happens to the hypertensive patient when the amlodipine samples run out? Does she have to buy more pills? Or does she change treatment every few months on the basis of what sample is in? For low-income patients there are better methods for obtaining necessary medicines. Many of the proven therapies are reasonably priced. A 1-month supply of hydrochlorothiazide is $7.92 and sulfamethoxazole-trimethoprim is $9 to $12 for a 2-week course, compared with amlodipine at $74 per month. For those physicians who want to use the newer medicines or brand names, nearly all the major drug companies have programs to supply medicine to low-income patients.
