Doctors spend a lot of time telling patients that there are no easy fixes. There is no substitute for regular physical activity, a sensible diet, and constant seatbelt use. Although Americans love shortcuts, there isn't a pill for everything, we say.
Except that we may be wrong. In this issue we reprint papers and an abstract by Wald and Law (BMJ USA p 476, BMJ USA p 482, BMJ USA p 498) proposing what they call the Polypill, which would combine six commonly available medications into one chemoprophylactic tablet. If taken by patients with heart disease and everyone over 55, Wald and Law state, the Polypill could reduce heart disease - related deaths by up to 80 percent: an astounding and already controversial claim.
BMJ readers clearly did not all agree that the Polypill articles made the June 28 issue what editor Richard Smith called “the most important BMJ in 50 years.” We've reprinted some of their most trenchant comments as well (BMJ USA p 481).
The press coverage of Wald and Law's modest proposal usually did not mention a second important finding of their work: the efficacy of low-dose combinations of antihypertensive medications. One of their meta-analyses (BMJ USA p 482) demonstrated that three antihypertensives taken at half dose provide 80 percent of the benefit with a dramatically reduced incidence of adverse effects. A case of where more may in fact be less, flying in the face of standard teaching that we shouldn't prescribe multiple medications for the same condition.
In another challenge to conventional wisdom, Hinman et al (BMJ USA p 493) studied physical therapist - applied therapeutic taping as a treatment for osteoarthritis of the knees. In a six-week randomized controlled trial they found a significant improvement in pain and disability scores in patients who had their knees taped, compared with two types of controls: a no-tape group and a group who received control taping. But a US orthopedic surgeon we asked to comment is not convinced (BMJ USA p 497).
Finally, Noakes points out (BMJ USA p 467) that the common practice of drinking large amounts of sports drinks before and during exercise is not only wrong but potentially dangerous. The evidence-based take-home message is to let thirst guide intake.
Common sense validated.
