Ethical pharmacists should not sequa

Ethical pharmacists should not sell quackery
Pharmacists often sneer at homeopathy and
other natural health quackery. But they do sell it, which on the face of it
contravenes the South African Pharmacy Council’s ethical rules. There should be
an “ethical pharmacy” certification in South Africa .
My
local pharmacy sells a product called Septoguard. On the box, it claims to be a
“natural antibiotic”. Unlike other antibiotics, however, it is freely
available, requiring no prescription.
Being
a curious, scientific sort, I rummaged inside the box, where I found a package
insert, just like you would with real medicine. Reading it, a few oddities
struck me.
The
pharmacological classification is “D: Unani-Tibb”. It is surprising that an
antibiotic would not be classified under the usual “A.20: Antimicrobial agents”
heading, or one of its sub-headings, because that is where antibiotics intended
for use in humans go.
It
is even more notable, however, that category D does not exist. Medicines Control
Council (MCC)regulation 25,
under the Medicines and Related Substances Control Act, says that there are
three classifications of medicine: A, intended for use in humans; B, for stuff
that doesn’t work on its own; and C, intended for veterinary use.
There
is no category D. So the pharmacological classification is entirely bogus,
designed only to make this snake oil look like real medicine.
For
the meaning of “Unani Tibb”, we go not to some weird new-age holistic magic
site, but, surprisingly, to the Western Cape
University ’s “School of Natural Medicine ”.
It flogs courses in alternative medicine, and belongs right up there with South Africa ’s
other schools of witchcraft and
wizardry.
It
claims that Unani Tibb is a “complete, scientific and
natural system of medicine”. However, it also admits that two thirds
of “natural medicines”
have no published scientific literature supporting their use. That leaves one
third, for which there is “some published literature”. That hardly sounds
complete and scientific. Frankly, there is “some published literature” for
almost anything.10
Unani
Tibb is based on “temperament”, and divides people into four broad categories:
“sanguinous, phlegmatic, melancholic and bilious”. Ergo, it still believes in
the four “humours”. It turns out that this is based on the 11th-century
writings of Avicenna, a Persian scholar, who in turn took the ideas from the
Greco-Roman writings of Hippocrates and Galen.
The
problem is that all this humour claptrap was scientifically discredited and
superceded in the mid-19th century by the “father of modern pathology”,Rudolf Virchow. Unlike with art, science does
not improve with age, and ancient “science” is not very far removed from
superstitious nonsense. Which is exactly what Unani Tibb is.
According
to the UWC, Unani Tibb includes “regimental therapies” such as cupping and
colour therapy, which have no basis in the credible medical literature. One journal,
dedicated to colour research, treats the subject with sarcasm bordering on
contempt, saying there is “compelling support for applying the caveat emptor principle
to colour psychology and colour therapy claims found in non-academic sources”.
In
other words, this stuff is unscientific bullshit, taught by a supposed
“university”. They should be ashamed of themselves.
This
antibiotic, Septoguard, says its “pharmacological action … is based on the
Unani-Tibb philosophy”. That’s as vague and non-specific as saying aspirin’s
pharmacological action is based on medical theory, except that it has even less
credibility. This makes it clear that there is no science that explains its
action, nor has it been subjected to testing, let alone to large-scale,
randomised, double-blind, placebo-controlled trials.
Often
viewed as a “gold standard” in medical testing, these trials are not as objective and distortion-free
as one might wish, but they go furthest to eliminate sources of
artefacts and bias in research. So-called natural remedies are
rarely tested for quality, safety, or efficacy, because such testing would
likely show the concoction to be ineffective, or have too many unwanted
side-effects.
As
a result of this lack of testing, Septoguard’s insert says there are no known
side-effects, nor are there symptoms of overdose. This is unlike any real
medicine ever. You can overdose on water, but not on this magic
concoction! But it you do happen get side-effects, the manufacturers urge you
to go see a real doctor.
The
claims of no side-effects are also implausible because Septoguard does contain
active herbal ingredients. These extracts are impure, containing everything and
anything they can squeeze out of a plant. Sometimes, herbs do contain useful
active ingredients – for example, aspirin is derived
from the bark of a willow tree – but they are also likely to contain
ingredients that have unwanted side-effects.
That’s
the difference between ancient herbal medicine (or “phytotherapy”, as the UWC
likes to call it) and modern pharmacy. Modern pharmacy tries to identify active
ingredients, provide them in a measured dose, and exclude ingredients that do
not contribute towards the desired outcome, thereby eliminating unnecessary
side-effects.
Herbal
medicine, by contrast, can be harmful,
because it has more ingredients, they are often toxic, and their composition
and dose are far less rigorously controlled. The notion that herbal medicine is
somehow safer than modern pharmaceuticals is logically nonsense.
By
definition, an antibiotic, natural or otherwise, is supposed to kill bacteria
and other microbes. This is why oral antibiotics are usually prescribed for a
limited time, because they often cause gastro-intestinal complications: they
kill essential gut microbes just as easily as they kill the microbes that cause
infection.
For
Septoguard, however, things are different. The package insert says you can use
it to treat various infections, but primarily, you should take it as a “daily
health supplement to boost the immunity”. If you’re taking an antibiotic that
you can take every day, indefinitely, without prescription, you’re not taking
an antibiotic. You’re taking a placebo with no known action.
The
Septoguard insert says is has not been evaluated by the Medicines Control
Council. Not that I hold much stock in government bureaucrats. Laws about
medicine classification, evaluation and scheduling do not prevent quacks from
sellingindustrial bleach enemas to the gullible mothers of children,
who proceed to burn out the child’s intestinal lining, fish it out of the
toilet, and post pictures to Facebook, believing them to be the parasites that
supposedly cause autism.
But
not having been evaluated by the Medicines Control Council (MCC) is an
admission that Septoguard has not been tested for quality, safety and efficacy for its intended purpose.
One might hope that the makers appealed to a private alternative for scientific
testing, but there is no claim whatsoever about the product’s quality, safety
or efficacy.
On
the contrary. The insert concludes by saying, “This medicine is not intended to
diagnose, treat, cure or prevent any disease.”
There
we have it. The product’s own insert says it doesn’t work, and is not intended
to work.
Of
course, this statement exploits a legal loophole. By not claiming to be
medicine, it avoids having to be registered as a medicine by the MCC. It does,
however, suggest that the maker has no confidence that the substance would pass
tests for quality, safety and efficacy.
Yet
the University of the Western Cape
will teach you all about its scientific underpinnings, and pharmacists will
proudly display it on their shelves, lending it a veneer of respectability that
real medical practitioners ought to be ashamed of.
Septoguard
is, of course, far from the only quackery sold in pharmacies. There are all
sorts of diet concoctions, supplements, and “natural” cures for everything that
would otherwise cost a lifestyle change or the price of a doctor’s visit.
Dis-Chem proudly advertises homeopathic remedies, despite the fact that
they consist of nothing but fairy-dust and magic.
As
a reminder, homeopathy is pseudoscience. It hasn’t just not been proven to
work, it has beenproven not to work any better than a placebo. Papers that
appear to conclude the opposite (but were actually inconclusive) have been
soundly discredited.
Homeopathy
holds that “like cures like”. This is, of course, absurd on the face of it.
Supporters like to compare it to vaccines (even though they’re typically
anti-vaxxers) because vaccines appear to be a scientific case of “like cures
like”. But they aren’t, and are nothing like homeopathy. Vaccines have active
ingredients in meaningful concentrations. They work to help the body fight
disease by training the immune system to respond effectively to pathogens. They
cure nothing, and in fact sometimes cause the disease against which they’re
meant to immunise. If you have polio, or smallpox, an additional dose of polio
or smallpox isn’t going to cure you. It’s going to make it worse. A vaccine
would only have helped if you received it before contracting the disease, not
after, as a cure.
Homeopathic
remedies are made from all sorts of poisons. The reason they rarely kill
anyone, however, is because they are diluted so much that none of the original
substance is likely to remain present in the solvent, which is usually water or
ethanol. (The exceptions are cases in which the dilution was not done
correctly.)
To
make it effective, and counter-intuitively make each successive dilution
stronger, homeopaths vigorously shake it to “potentise” it. This has something
to do with the “structure” of water (it has none, on normal timescales), which
gives it “memory”. If it did, of course, it would retain “memory” of a lot of
stuff other than the ingredients the homeopath intended, like sewerage. If it
had any potency at all, it would probably kill you.
There
simply is no plausible scientific explanation for why homeopathy might work,
and it has never been shown to work in large-scale, randomised, double-blind,
placebo-controlled trials.
Herbal
and other untested remedies can have actual harmful effects, but homeopathy’s
harm lies exclusively in convincing people to forgo real medicine, and becoming
sicker or dying when they might have been cured. It ought not to be sold by
responsible pharmacies that claim to act in the best interests of their
customers’ health.
It
is ironic that proponents of various natural and alternative health products so
often accuse the pharmaceutical industry of being craven, greedy corporations
driven by profit above human health. Sure they are. But every business is
driven by profit.
That
is true for pharmacies, but also for naturopathic quackery. This junk gets sold
to ignorant, gullible or desperate people, with no intention of healing them
and every intention of parting them from their money. Most pharmacists will
happily sell you both proven pharmaceuticals and untested quackery, because it
makes a profit.
But
they shouldn’t. When a pharmacist openly admits that some of the stuff on his
shelves doesn’t work, and is overpriced to boot, it is unethical to continue
selling it to ignorant people, desperate for a cure for whatever ails them.
In
fact, the South African Pharmaceutical Council (SAPC), in its ethics rules,
says a pharmacist may not advertise medicines “in any manner that is not
factually correct; that is misleading; or that harms the dignity or honour of
the profession”.
Most
natural and alternative remedies, not to mention slimming products,
muscle-building products, immune-boosting products, vitamins, and countless
other products on the pharmacy shelves, cannot be called “medicine” without
being factually incorrect and misleading. A tiny line in the package insert
that says it isn’t really medicine is not sufficient to change that.
When
there is no credible scientific evidence for the safety and efficacy of a
product, and the package insert even admits this, it should not be on the
shelves of a respectable pharmacist. It should be limited to the shopfronts of
quacks and charlatans. At least when you buy from them, you know you’re not
giving your money to someone who claims to uphold scientific standards.
Of
course, one could make a law about this, but the law is a blunt tool. And it
appears that the statutory SAPC is unable or unwilling to enforce its own
ethical rules.
Instead,
professional associations or patients’ advocacy groups might compete to issue
“ethical pharmacist” certifications, which assure customers that pharmacies do
not sell ineffective or even dangerous quackery. It might appear more
profitable to do so, but only in the sense that fraud and misrepresentation are
“profitable”. In the long run, most people will want to patronise honest
professionals for their healthcare.
I,
for one, find it deeply troublesome that my medicine gets selected from stock
that includes snake oil and magic. This fraud harms people, and ethical
pharmacists should see an end to it. DM
