It's hard to turn on TV without being bombarded with ads for prescription drugs, offering cures for everything from EDS to acid reflux. The American Medical Association says many of the ads contain misleading information and need tighter controls.

AMA President-elect Dr. Nancy Nielsen expressed her organizations concerns in testimony before the House Energy and Commerce Committee Subcommittee on Oversight and Investigations.

"Direct-to-consumer ads often portray drugs through rose-colored glasses by including more information about a drug's benefits than risks," said Nielsen. "Imbalances in these ads can diminish patient understanding of certain drug risks, and increase the need for an ongoing dialogue between patients and physicians about the benefits and risks of prescription drugs."

Critics have long pointed out that consumers are in no position to purchase prescription drugs without their doctor. The sole point of advertising to consumers, they claim, is to prompt consumers to specifically request a particular prescription drug.

At the hearing, the AMA discussed the need for FDA regulation over DTCA and shared guidelines for DTCA that address advertising content, disclosures, and audiences targeted.

"The AMA guidelines for DTCA can help ensure that patients receive information about prescription drugs that is accurate, educational, well-balanced and encourages patient-physician communication," Nielsen said.

"We look forward to working with Congress to achieve our shared goal - that direct-to-consumer advertisements focus on truly helping patients rather than maximizing pharmaceutical companies' bottom line," she added.

The ads work

A study last year bolsters the doctors' argument. A poll of Pennsylvania adults, taken 10 years after the first direct-to-consumer pharmaceutical television advertisement ran, suggests that nearly half of the participants have asked their doctor about a specific prescription drug or medical procedure they saw advertised.

According to The Patient Poll, conducted by the Pennsylvania Medical Societys Institute for Good Medicine, 45 percent of Pennsylvania adults participating in the summer 2007 poll indicated that they have talked to their doctor about a specific drug and/or procedure that they saw advertised on television or in a magazine.

Critics of the ads say they lead to more prescriptions being written, often when it's not in the best interest of the patient. But theres also a flip side: instead of getting upset about this situation, one physician says its better for his colleagues to be prepared for questions.

Most physicians are divided about whether or not pharmaceutical advertisements directed towards patients are good, said Dr. Peter Lund, founder of the Pennsylvania Medical Societys Institute for Good Medicine.

Some say its good to have patients informed, while others say its bad because of induced demand and incorrect self-diagnosing. Our advice to Pennsylvania physicians is to be alert to whats being advertised and be prepared to answer questions since theres a good chance theyll be asked.

A study published in the August 16, 2007, edition of The New England Journal of Medicine tracks a rise in total spending on pharmaceutical promotion from $11.4 billion in 1996 to $29.9 billion in 2005. Real spending on direct-to-consumer advertising increased by 330 percent during those years.

Theres clear evidence that the pharmaceutical industry is spending more to promote medications, Lund, an Erie, Pennsylvania urologist and incoming president of the Pennsylvania Medical Society, said. If it wasnt working for them, they wouldnt be pumping more money into that budget area.

While direct-to-consumer pharmaceutical advertisements can be traced back to 1981, the debate on advertising directly to patients accelerated within the medical community 10 years ago when the Food and Drug Administration changed policy to allow television advertisements directed towards patients.

I dont know a physician who hasnt been asked by at least one patient about a specific drug they saw advertised, Lund said.

Viagra ads

Some drug ads are more controversial than others. The AIDS Healthcare Foundation (AHF) last year filed a lawsuit against Pfizer Inc., the world's largest pharmaceutical company and manufacturer of impotence drug Viagra, over its marketing tactics and advertising.

AHF claims that Pfizer's Viagra advertising "has caused an increase in the spread of sexually transmitted diseases including but not limited to HIV/AIDS."

"Pfizer has engaged in and continues to engage in this conduct despite clear evidence of its illegality and harmful effects," the foundation charged. The lawsuit was filed in Los Angeles Superior Court.
